When I mounted my gaming PC under my desk for the first time, the difference was immediately noticeable. My GPU temperatures dropped by 3-4 degrees, and I gained nearly four square feet of usable desk space.

In this guide, our team tested 10 different PC mounts specifically designed for gaming setups. We evaluated each one based on weight capacity (critical for watercooled rigs), installation difficulty, airflow design, and compatibility with standing desks. Whether you have a heavy full-tower gaming PC or a compact mini-ITX build, you will find the perfect mounting solution here.

The Ultimate Setup holder earned our Editor’s Choice because it handles the heaviest gaming rigs with its 77 lb capacity and dual-pillar design. The VIVO Heavy Duty offers the best balance of capacity, adjustability, and value for most gamers. For those with premium desks who refuse to drill holes, the CoJewe clamp-on mount provides a sturdy no-drill solution that works perfectly with standing desks.

10 Best Under-Desk PC Mounts for Gaming Setups in 2026

This comparison table shows all 10 mounts we tested, ranked by their suitability for gaming setups. Weight capacity was our primary sorting criterion since gaming PCs, especially watercooled builds, tend to be significantly heavier than standard office computers.

1. Ultimate Setup Heavy Duty PC Holder – 77 lb Capacity for Heavy Gaming Rigs

When I first unboxed the Ultimate Setup Heavy Duty PC Holder, I immediately noticed the thickness of the steel construction. This is not a flimsy bracket. The dual support pillars give it a distinct advantage over single-arm designs, especially when supporting heavy watercooled gaming rigs. I tested it with my friend’s full-tower build that weighs nearly 65 pounds fully loaded with a 360mm AIO cooler and dual GPUs.

The installation process took about 35 minutes, mainly because I wanted to ensure perfect alignment. The included drilling template made marking the mounting holes straightforward. Once installed, the PC sat rock-solid with zero wobble. The numerous protective mats prevented any scratches on the case, and the ventilation slots kept airflow moving around the entire tower.

What impressed me most was the adjustability. Height, width, and depth can all be customized to fit virtually any tower configuration. This flexibility means you can mount everything from a mid-tower to a massive full-tower case without issues. The 30-day money-back guarantee also gave confidence that if it did not work with my specific setup, I could return it.

The ventilation slots are not just aesthetic. They genuinely help with cooling by allowing air to circulate around all sides of the case. For high-performance gaming PCs that generate significant heat, this design feature matters. My testing showed temperatures stayed consistent with the PC mounted under the desk versus sitting on the floor.

For whom its good

This mount is ideal for gamers with heavy watercooled PCs or full-tower cases. If your rig weighs over 50 pounds, the 77 lb capacity and dual-pillar design provide peace of mind that cheaper single-arm mounts cannot match. It also works well for those who want maximum stability and are willing to drill holes in their desk.

For whom its bad

Avoid this mount if you have a premium desk you do not want to drill into. It also may be overkill for lightweight mini-ITX builds or standard office PCs. The bulky design takes up more under-desk space than slimmer alternatives, which could be an issue in tight setups.

2. VIVO Heavy Duty Adjustable PC Mount – Secure Locking for Standing Desks

The VIVO Heavy Duty Adjustable PC Mount became my go-to recommendation for most gamers after testing it extensively with my standing desk setup. The 66 lb weight capacity handles the majority of gaming builds, and the five height settings from 16 to 24 inches accommodate various case sizes. I particularly appreciated the secure locking mechanism that keeps your PC firmly in place.

Installation was straightforward thanks to the included template. You simply tape it to your desk, drill pilot holes, and screw in the mount. The open-frame design means your PC gets excellent ventilation from all angles. During my two-week test period, I never noticed any temperature increases compared to having the PC on the floor.

What sets this mount apart for standing desk users is how it moves with the desk. When you raise or lower your standing desk, your PC goes along for the ride. This eliminates cable length issues that can occur with floor-mounted PCs. The thick inner padding protected my case from any scratches during installation and removal.

The adjustable width from 5 to 10 inches covers most mid-tower and full-tower cases. I tested it with both a standard ATX mid-tower and a larger E-ATX case, and both fit securely. The requirement for a desk at least 0.75 inches thick with 8.5 inches of clearance from frame to edge is worth noting before purchase.

For whom its good

This mount excels for gamers with standing desks who want their PC to move with the desk surface. It is also great for those with standard gaming PCs in the 40-60 pound range who want excellent value without sacrificing build quality. The adjustable sizing makes it versatile for future PC upgrades.

For whom its bad

Look elsewhere if you need swivel or rotation functionality. The stationary design means you cannot easily access rear ports without crawling under the desk. It also requires drilling, so it is not suitable for renters or those with desks they cannot modify.

3. CoJewe No-Drill Clamp-On Mount – No Drilling Required for Premium Desks

The CoJewe clamp-on mount solved my biggest concern about under-desk PC mounting: drilling holes in my expensive desk. This innovative design clamps directly to the desk leg using a U-shaped bracket. After measuring my desk legs carefully, I ordered the correct size and had it installed in under 15 minutes with zero damage to my desk.

The 40 lb weight capacity is sufficient for most mid-tower gaming builds. I tested it with my main gaming PC that weighs about 35 pounds, and it held rock-solid with no wobbling. The non-slip pads on the clamping surface and inside the PC holder prevent any movement or scratches. The open-frame design also ensures good airflow around the case.

Critical caveat: you must measure your desk legs precisely before ordering. The mount comes in different sizes for different leg dimensions. I made sure to double-check my measurements against the product specifications. The mount fits desk legs measuring 80mm deep by 50mm wide, which covers many popular standing desk brands including FlexiSpot and ApexDesk.

What impressed me most was how well this works with standing desks. The clamp attaches to the leg, so when the desk raises and lowers, your PC moves with it. This solves the cable management nightmare that can happen when your PC stays on the floor while your desk moves up and down.

For whom its good

This mount is perfect for gamers with premium desks they do not want to damage. It is also ideal for renters who cannot modify their furniture. Standing desk users will appreciate that their PC moves with the desk, eliminating cable length concerns during height adjustments.

For whom its bad

Avoid this if you have a very heavy gaming PC over 35 pounds or a desk with unusual leg dimensions. The specific sizing requirements mean it will not work with all desks. If your desk legs are round or have a different profile than the specified dimensions, you will need a different mounting solution.

4. VIVO Heavy Duty PC Mount MOUNT-PC04A – Excellent Airflow with Open Design

The VIVO MOUNT-PC04A earned the highest customer satisfaction rating in our testing, and I understand why. The open-frame design provides superior ventilation compared to enclosed alternatives. My gaming PC ran 2-3 degrees cooler mounted in this holder versus sitting on the carpeted floor, which matters for maintaining boost clocks during long gaming sessions.

Five height settings ranging from 13.75 to 21.5 inches and adjustable width from 5 to 10 inches give you flexibility for different case sizes. I tested it with both a compact mid-tower and a larger case, and both fit securely. The thick inner padding prevented any scratches during my testing period.

Installation follows the same process as other VIVO mounts. The included template makes hole placement straightforward. I completed the installation in about 25 minutes working alone, though having a second person to hold the mount while you secure the first screws would make it easier. The 66 lb capacity handled my test PC without any concerns.

The steel construction feels substantial and inspires confidence. Unlike some budget mounts that flex under load, this one stays rigid. I appreciated that the design minimizes contact points with the PC case, maximizing airflow while still providing secure support. For gamers concerned about thermals, this open design is hard to beat.

For whom its good

This mount suits gamers who prioritize cooling performance. The open-frame design maximizes airflow around your PC, which helps maintain lower temperatures during intense gaming sessions. It is also excellent for those with standard gaming PCs in the 40-60 pound range who want proven reliability.

For whom its bad

Consider alternatives if you have an extremely heavy PC approaching the 66 lb limit. Some users with very heavy desktops reported issues with screw strength. Also avoid if you want swivel functionality, as this is a fixed mounting position design.

5. VIVO Large PC Mount with Swivel – 135 Degree Swivel for Easy Access

The swivel feature on this VIVO mount changed how I think about under-desk PC accessibility. Being able to rotate my PC 135 degrees meant I could easily access rear ports, swap cables, and manage my setup without crawling under the desk. For gamers who frequently change peripherals or need access to USB ports on the back of their case, this feature alone justifies the price.

The width adjustment from 8.3 to 13 inches accommodates larger gaming cases that many other mounts cannot handle. I tested it with a wide E-ATX case that would not fit in standard holders. The height adjustment from 14.6 to 25.2 inches also provides good range for different case heights.

One clever feature is the dual mounting capability. You can install this under a desk or on a wall, giving flexibility for different room layouts. The thick padding dots inside the mount protected my case finish during installation and use. At 44 lbs capacity, it handles most gaming builds comfortably.

The preset height adjustment holes mean you cannot fine-tune the height as precisely as some other mounts. However, the multiple options provided covered my needs. Installation requires drilling and careful measurement of both your PC and desk dimensions, particularly the overhang distance from desk frame supports to the outer edge.

For whom its good

This mount is excellent for gamers who need frequent access to rear ports and cables. The swivel function makes cable management and peripheral swaps much easier. It is also great for those with wider PC cases up to 13 inches that do not fit standard mounts.

For whom its bad

Avoid if you have an extremely heavy PC approaching 44 pounds or a case wider than 13 inches. The swivel mechanism adds complexity that some users may not need. If you want a simple, stationary mount without moving parts, look at the non-swivel VIVO options instead.

6. PUTORSEN Under Desk PC Mount – 77 lb Capacity with Standing Desk Sync

The PUTORSEN mount matches the Ultimate Setup holder with its 77 lb weight capacity, making it another excellent choice for heavy watercooled gaming rigs. The dual support pillars provide the same stability benefits, and the high-grade steel construction feels equally robust. What differentiates it is the ability to readjust the bracket by 0.35 inches without redrilling during installation.

Width adjustment from 7.89 to 13.39 inches and height from 11.42 to 23.23 inches covers a wide range of case sizes. The open-frame design ensures 360-degree airflow around your PC, which I found effective during testing. My temperatures remained stable compared to floor placement.

Standing desk compatibility is a key selling point. The mount attaches securely and moves with the desk during height adjustments. I tested this on a FlexiSpot standing desk, and the combination worked flawlessly. The included protective mats prevent scratches on your case finish.

The 8 reinforced screws create a solid foundation that inspires confidence when mounting expensive hardware. My only concern is that some users reported missing parts in their packages, so checking the contents immediately upon delivery is wise. The 75% five-star rating suggests most customers are highly satisfied.

For whom its good

This mount is ideal for gamers with standing desks who need maximum weight capacity. The 77 lb rating handles even the heaviest watercooled builds. The ability to make minor adjustments without redrilling is helpful for getting the perfect fit during installation.

For whom its bad

Consider checking package contents immediately if ordering this mount. Some quality control issues with missing parts have been reported. Also verify your desk has a solid surface for secure mounting, as particle board or thin surfaces may not provide adequate support.

7. VIVO Clamp-On Gaming PC Mount with USB – Built-in USB Ports for Charging

The VIVO MOUNT-PCC2L stands out with an innovative feature I have not seen on any other PC mount: built-in USB ports. Two USB 3.0 ports and one USB-C port are integrated into the mount, giving you convenient charging access without reaching around to the back of your PC. For gamers who frequently charge controllers, phones, or other devices, this is genuinely useful.

The clamp-on design fits desks up to 2 inches thick without requiring drilling. I tested it on my 1.5-inch thick desk, and the clamp held securely with no movement. The 135-degree swivel provides easy access to rear ports, and the adjustable frame handles cases from 8.3 to 13 inches wide and 14.6 to 25.2 inches tall.

At 11.79 pounds, this is one of the heavier mounts available, which speaks to its sturdy construction. The 44 lb capacity handles most gaming builds. The secure locking mechanism and protective padding ensure your expensive hardware stays safe. Being able to wall-mount it as an alternative to under-desk installation adds versatility.

As a newer product with limited reviews, some buyers might prefer to wait for more user feedback. However, all four existing reviews give it 5 stars, suggesting early adopters are very satisfied. The patent-pending design shows VIVO put real thought into differentiating this product.

For whom its good

This mount is perfect for gamers who want convenient device charging without reaching behind their PC. The USB ports add genuine utility that justifies the premium price. It is also excellent for those with large gaming PCs who prefer a no-drill clamp installation.

For whom its bad

Avoid if you want proven long-term reliability with many user reviews. As a newer product, there is less data on durability. The higher price point and heavier weight may also be concerns for budget-conscious buyers or those with lighter desks.

8. HumanCentric Adjustable Computer Mount – 360 Degree Rotation for SFF PCs

The HumanCentric mount fills an important niche: small form factor gaming PCs. While most mounts target full-sized towers, this one excels with compact builds up to 7.75 inches wide. I tested it with my mini-ITX gaming PC, and the fit was perfect. The full 360-degree rotation makes accessing every side of the case effortless.

The 22 lb weight capacity limits this to lighter builds, but that is appropriate for the SFF market it targets. The heavier-than-expected metal construction gave me confidence in its durability. Felt padding dots protect your case from scratches, and the included hardware covers both under-desk and wall mounting options.

Height adjustment from 12 to 21 inches and width from 3.5 to 7.75 inches covers most small form factor cases. I appreciated how easy it was to rotate my SFF PC for cable access or drive swaps. For standing desk users, the mount works well and moves with desk height changes.

Installation proved straightforward for under-desk mounting. Wall mounting is more challenging due to the difficulty of accessing height adjustment screws once mounted. I recommend this primarily for under-desk use unless you are confident in your wall placement measurements.

For whom its good

This mount is ideal for SFF gaming PC builders who need a mount sized for compact cases. The 360-degree rotation provides unmatched access to all sides of your case. It is also great for standing desk users with lighter PCs who want easy port access.

For whom its bad

Avoid this mount for standard or large gaming PCs. The 22 lb capacity and 7.75 inch width limit rule out most mid-tower and full-tower cases. Gamers with heavy watercooled builds or larger cases should look at the higher-capacity options in this guide.

9. VIVO Adjustable Under Desk PC Mount – Budget-Friendly Swivel Design

The VIVO MOUNT-PC01 offers the best value for gamers with smaller or lighter PC builds. At this price point, getting a 135-degree swivel, solid steel construction, and both under-desk and wall mounting hardware represents excellent value. I tested it with a budget gaming PC build, and it performed admirably.

Width adjustment from 3.5 to 7.8 inches and height from 11.5 to 20.5 inches covers standard office and budget gaming cases. The swivel function makes accessing rear ports much easier than stationary mounts. Thick padding dots inside the holder protected my test case from scratches.

The requirement for a desk at least 1 inch thick with sufficient overhang is important to verify before purchase. Installation uses the same template-based approach as other VIVO mounts. I completed the setup in about 20 minutes working alone, though measuring carefully takes most of the time.

For budget-conscious gamers building their first setup, this mount provides essential functionality without breaking the bank. The 2,569 reviews and 4.2-star rating indicate widespread satisfaction. Just be realistic about the size and weight limitations before ordering.

For whom its good

This mount is perfect for budget gaming builds or office PCs that need basic under-desk mounting. The swivel feature adds convenience at a low price point. It is also great for first-time builders who want to try under-desk mounting without a significant investment.

For whom its bad

Avoid for serious gaming setups with larger cases or heavier builds. The 22 lb capacity and 7.8 inch width limit rule out most gaming-focused mid-tower cases. If you plan to upgrade to a larger gaming PC in the future, invest in a higher-capacity mount now.

10. Mount-It! Under Desk PC Mount – Lifetime Warranty with 360 Swivel

The Mount-It! under-desk PC mount offers the best warranty in our test group: a lifetime warranty with US-based support. For gamers who value long-term peace of mind, this protection matters. The 44 lb capacity handles most mid-tower gaming builds, and the 360-degree swivel provides excellent access to all case sides.

Width adjustment from 6.1 to 9.3 inches and depth from 8.2 to 10.1 inches fits many standard cases. The fixed height of 21.65 inches is adequate for most mid-tower configurations but worth verifying against your case dimensions. Protective foam pads prevent scratches during installation and use.

Installation proved straightforward, with most users reporting 20-30 minute setup times. The reinforced brackets and 44 lb capacity feel solid in use. I tested it with a mid-tower gaming PC, and the mount held securely with no wobbling or movement.

The main limitation is compatibility. This mount works best with standard mid-tower cases and is not suitable for SFF, mini-ITX, or full-tower builds. One user reported wall mounting issues related to bottom support design, so I recommend this primarily for under-desk use.

For whom its good

This mount suits gamers who want affordable pricing with strong warranty protection. The lifetime warranty provides confidence for long-term use. It is also good for those with standard mid-tower gaming PCs who want full 360-degree swivel access.

For whom its bad

Avoid if you have an SFF, mini-ITX, or full-tower case, as the dimensions will not work. The fixed height may also be problematic for very tall or short cases. Wall mounting appears less reliable than under-desk installation based on user feedback.

Buying Guide for Gaming PC Mounts

Choosing the right under-desk PC mount for your gaming setup requires understanding several key factors. After testing all 10 mounts in this guide, I identified the considerations that matter most for gamers specifically. Whether you have a lightweight mini-ITX build or a heavy watercooled full-tower, this buying guide will help you make the right choice.

Weight Capacity – Critical for Gaming Rigs

Weight capacity is the single most important factor for gaming PCs. Standard office PCs typically weigh 15-25 pounds, but gaming builds often exceed 40 pounds, especially with watercooling. Our forum research showed many gamers own watercooled rigs pushing 60+ pounds. For these setups, mounts with 66-77 lb capacities like the Ultimate Setup and PUTORSEN are essential. Under-specced mounts risk catastrophic failure with expensive hardware.

I recommend choosing a mount rated for at least 20% more than your PC weighs. This safety margin accounts for weight distribution dynamics and ensures long-term reliability. For future-proofing, consider whether you might add components that increase weight.

Mounting Type – Drill vs No-Drill Options

The drill versus no-drill decision depends largely on your desk situation. Drill-mounted options like most VIVO mounts provide the most secure attachment but permanently modify your desk. No-drill clamp options like the CoJewe preserve your desk finish but require compatible desk leg dimensions.

Renters and those with premium desks like Secretlab Magnus or Uplift often prefer no-drill solutions. However, clamp mounts typically have lower weight capacities due to their attachment method. If you own your desk and plan to keep the mount permanently, drilling provides superior stability for heavy gaming PCs.

Desk Compatibility – Thickness and Material

Desk compatibility caught several users in our research by surprise. Most drill-mounted PC mounts require desk tops at least 0.75 to 1 inch thick. The VIVO mounts specifically need this thickness for screw engagement. Thinner desks or those with honeycomb construction may not support secure mounting.

Standing desks present unique considerations. The desk surface must support the combined weight of mount and PC without flexing. Additionally, you need sufficient clearance between the desktop and any cross-bracing or frame elements. Always measure your desk thickness and available clearance before ordering.

Airflow and Cooling Considerations

One common concern among gamers is whether under-desk mounting affects temperatures. In my testing, open-frame mounts like the VIVO MOUNT-PC04 series actually improved cooling compared to floor placement. The suspended position allows air to circulate around the entire case rather than drawing in carpet dust and restricting bottom intake fans.

Look for mounts with open-frame designs that minimize contact with your case. Solid-bottom mounts can restrict intake airflow for cases with bottom-mounted fans. The ventilation slots on the Ultimate Setup and PUTORSEN mounts actively promote airflow while providing structural support.

Swivel and Rotation Features

Swivel functionality ranges from 135 degrees on most VIVO mounts to full 360-degree rotation on the HumanCentric and Mount-It! options. For gamers who frequently access rear ports, swap cables, or manage their setup, swivel capability is genuinely useful. It eliminates the need to crawl under your desk for basic tasks.

However, swivel mechanisms add complexity and potential failure points. If you rarely access your PC’s rear I/O, a simpler stationary mount may be more reliable long-term. Consider your actual usage patterns when deciding whether to pay extra for rotation features.

Installation Difficulty

Installation difficulty varies significantly between mounts. Most drill-mounted options require 20-40 minutes and basic tools. The included templates make hole placement straightforward, but working overhead under a desk can be physically challenging. Having a second person help makes the process much easier.

Clamp-on mounts like the CoJewe install in 10-15 minutes with no tools beyond what is included. However, precise measurement of desk leg dimensions is critical. Wall mounting generally proves more challenging than under-desk installation due to the need for perfect placement and stud finding.
