AI Verdict
A cheap, all-aluminum GPU brace that screws directly into your bottom case fans, perfect for compact builds where standard magnetic stands won't fit.
This bracket is a lifesaver if you have bottom intake fans directly under your GPU, but it fails completely in standard ATX cases with empty space above the PSU shroud. The 128mm max height strictly limits it to compact builds or thick 4-slot cards.
If you have a standard mid-tower case, look for a magnetic base bracket that extends up to 190mm instead.

Chance this product isn't for you
Pros
- Mounts directly to 120mm or 140mm bottom intake fans using included screws
- Adjustable height up to 128mm accommodates thick 3-slot and 4-slot GPUs
- CNC anodized aluminum construction prevents the bending common in cheap plastic brackets
- Includes a mini bubble spirit level to guarantee your graphics card sits perfectly flat
- Rubberized contact pads prevent the metal arms from scratching your GPU shroud
Cons
- Base mounting holes are sometimes poorly machined, making the included screws hard to thread
- Maximum 128mm height is too short for mid-tower cases without bottom fans
- Black anodized coating chips easily during installation
- Requires exposed bottom fan mounts directly under the GPU to work
Dimension Scores
It's a piece of metal that holds your card up, it won't give you extra frames.
The narrow base plate mounts directly over the fan hub without blocking airflow to the GPU.
Requires 0W of power since it has no RGB lighting or electronic components.
This is a structural bracket, not a graphics card, so it has 0GB of VRAM.
Best For
- Mini-ITX and Micro-ATX builds with bottom intake fans
- Heavy triple-fan GPUs like the RTX 4080 or 4090 in compact cases
- Cases where a traditional magnetic base bracket has nowhere flat to sit
Not Recommended For
- Standard ATX mid-towers with a large gap between the PSU shroud and the GPU
- Cases without bottom-mounted 120mm or 140mm fans
Watch Out For
- The included mounting screws don't always fit the base plate holes cleanly due to rough machining.
- The 128mm maximum height means this won't reach your GPU if you have a standard ATX case with a low PSU shroud.
- You must have a 120mm or 140mm fan positioned exactly under the GPU sag point, or the bracket has nothing to mount to.

What Buyers Say
The most surprising thing about this bracket is that it actually includes a tiny bubble level, which takes the guesswork out of fixing GPU sag. Buyers constantly mention it solves the specific problem of mounting a brace in cases where the bottom is entirely covered by intake fans. The machining quality is a gamble, with multiple reports of poorly threaded screw holes. The 128mm height limit also catches a lot of people off guard when it fails to reach their graphics card.
“Finally a bracket that works with my bottom fans, but I had to force the screws in because the holes were machined so poorly.”
Common Praise
- Mounts securely to bottom fans where magnetic stands would just fall over
- Included bubble level makes it incredibly easy to get the card perfectly straight
- Thick aluminum construction doesn't flex even under 2.2kg RTX 4090 cards
- Narrow base design doesn't restrict airflow from the intake fans
Common Complaints
- Screw holes on the base plate are often poorly threaded or too small
- 128mm maximum height is way too short for standard mid-tower cases
- Black paint chips off easily if you scrape the metal parts together
- Instructions are practically non-existent in the box
Ownership Tips
- The rubber pads compress slightly over the first week, requiring a minor height readjustment.
- If your bottom fans vibrate at high RPMs, the bracket can transfer that vibration to the GPU shroud.
- The dual-brace arms can be rotated to support the card from the side rather than just the bottom.
Frequently Asked Questions
Does this mount to the case or the fan?
It screws directly into the mounting holes of a 120mm or 140mm bottom case fan. You use the included longer screws to secure it through the fan frame.
Will this reach my GPU in a standard ATX case?
Probably not. The maximum height is 128mm, which is usually too short to bridge the gap from a PSU shroud to the GPU in a full-size case.
Does it block airflow from the bottom fan?
No. The base plate is a narrow metal strip that sits across the fan hub and frame, leaving the fan blades completely unobstructed.
What tools do I need to install this?
None. The package includes a small screwdriver, the necessary mounting screws, and a mini bubble level to check your GPU alignment.
Can I use this without a bottom fan?
Yes. If your case has 120mm or 140mm fan mounting rails directly under the GPU, you can screw the bracket into those rails.
Buying Guide
When buying a GPU support bracket, the only thing that actually matters is the distance between your case floor and the bottom of your graphics card. Measure this gap before you buy anything. This specific bracket is designed to screw into bottom-mounted case fans, making it a niche solution for compact cases. If you have a flat metal PSU shroud under your GPU, you don't need this—get a magnetic stand instead.
128mm Maximum Height
This is the absolute tallest the bracket can reach. Think of it like a ladder—if the roof is 6 inches away and your ladder is only 5 inches, it's useless.
120mm/140mm Fan Mounting
The base plate holes are spaced exactly to match standard PC case fans, letting you piggyback the bracket onto your existing cooling setup.
CNC Aluminum Construction
Unlike cheap plastic brackets that warp under the heat of a gaming PC, aluminum stays rigid and won't slowly bend over time.
Alternatives
If the gap under your GPU is larger than 128mm, search for a 'magnetic GPU support stand 190mm'. If you want something that hides completely, look for a 'motherboard standoff GPU bracket'.
