AI Verdict
This $10 aluminum cylinder uses a simple screw mechanism and magnetic base to fix GPU sag for anyone with a 74-120mm gap above their power supply shroud.
This bracket is flawless for standard ATX cases with steel shrouds, but its 74mm minimum height makes it physically incompatible with many modern micro-ATX setups housing 3.5-slot GPUs. You must measure the exact clearance under your graphics card before ordering.
If your clearance is under 74mm, buy the nkomax Mini (26-50mm) version instead.

Chance this product isn't for you
Pros
- All-aluminum construction easily supports 2.2kg cards like the RTX 4090 without flexing
- Threaded screw mechanism allows precise millimeter-by-millimeter height adjustments from 74mm to 120mm
- Hidden magnetic base snaps firmly onto steel PSU shrouds to prevent accidental knock-overs
- Top rubber anti-scratch pad protects your GPU backplate or fan shroud from metal-on-metal contact
- Compact footprint doesn't block bottom intake fans or disrupt case airflow
Cons
- Magnetic base is useless on plastic PSU shrouds or aluminum cases like the Lian Li O11 Dynamic
- Minimum height of 74mm means it won't fit in tight micro-ATX builds with thick GPUs
- Lacks a locking nut, so heavy case vibrations could theoretically cause the screw to slowly unthread
Dimension Scores
It is a metal stick that prevents your heavy GPU from snapping its PCIe slot, keeping your rig alive to game.
The tiny footprint blocks zero airflow, and the rubber pad prevents metal-on-metal rattling noises.
It is a passive piece of aluminum that draws exactly 0 watts.
This cylinder contains zero gigabytes of VRAM.
Best For
- Mid-tower and full-tower ATX cases with steel power supply shrouds
- Heavy 3-slot and 4-slot GPUs like the RTX 4080 or 4090
- Minimalist PC builds where you want to hide the support bracket
Not Recommended For
- Small form factor (SFF) or ITX builds where the GPU-to-floor gap is under 74mm
- Cases with plastic or glass bottoms where the magnet cannot grip
Watch Out For
- Measure your gap before buying — if the distance from your case floor to the GPU is less than 74mm (2.9 inches), this Large size will not fit and you need the Mini version.
- The magnet only sticks to steel — if your case has a plastic shroud or is made of aluminum, the bracket can slide around if you move the PC.
- Watch your fan blades — you must position the top rubber pad precisely on the GPU's plastic frame so it doesn't rub against spinning fans.

What Buyers Say
Reading through reviews, the sheer relief of fixing severe GPU sag on massive 40-series cards with a $10 piece of metal is obvious. The heavy-duty aluminum feel and the rubberized top protecting the GPU shrouds get constant shoutouts. The biggest point of frustration comes from people who skipped measuring their case clearance and found the 74mm minimum height too tall for their micro-ATX builds. A few people also noted the magnet is completely useless on premium aluminum cases or plastic PSU shrouds.
“Fixed the terrifying lean on my 4080 super in 10 seconds flat, just make sure you actually measure the gap first because I almost bought the wrong size.”
Common Praise
- Eliminates up to 5mm of sag instantly on heavy 3-slot and 4-slot cards
- Threaded design allows for exact millimeter-perfect height adjustments
- All-aluminum build feels significantly more premium than plastic alternatives
- Magnetic base snaps securely to steel case basements
Common Complaints
- 74mm minimum height is too tall for thick GPUs in smaller cases
- Magnet does not stick to aluminum cases or plastic shrouds
- Base is too wide to sit securely on the center hub of some 120mm bottom intake fans
- Lacks a locking nut to secure the height permanently
Ownership Tips
- The threading stays firmly in place under the weight of the GPU, even without a locking nut
- If you move your PC to clean it, you'll need to double-check the bracket as it can slide slightly
- The rubber pad collects a bit of dust over time but remains grippy
Frequently Asked Questions
Will the magnet damage my hard drives or PC components?
No. The magnet is relatively weak and localized to the base, posing zero risk to modern SSDs or shielded components.
Does this fit the RTX 4090?
Yes. The aluminum body easily supports the 4+ pound weight of an RTX 4090 without bending.
How do I know if I need the Large or Small size?
Grab a ruler and measure the gap between your case floor and the bottom of your GPU. If it is between 74mm and 120mm, buy this Large version.
Can I use this if I have bottom intake fans?
Yes, but you have to rest the base on the fan hub (the solid center) or the narrow plastic frame between the fans.
Does it lock in place once adjusted?
There is no dedicated locking nut, but the threading is tight enough that the weight of the GPU keeps it from spinning down on its own.
Buying Guide
You are buying a threaded aluminum cylinder to hold up a heavy piece of tech. The only thing that actually matters here is the physical distance between your case floor and your graphics card. Grab a tape measure before you hit buy. If your case is made of aluminum or has a plastic shroud, know that the magnetic base won't do anything, and the bracket will just rest in place via gravity.
74-120mm Height Range
This is the exact physical gap this bracket can fill. Think of it like a car jack — if your car is too low to the ground, the jack won't fit underneath.
All-Aluminum Construction
Unlike cheap plastic brackets that can warp under the heat and weight of a 4-pound GPU, metal stays rigid forever.
Magnetic Base
Helps the stand grip the steel floor of your PC case so it doesn't get knocked over when you bump your desk.
Alternatives
If your gap is smaller than 74mm, search for a 'mini GPU brace' or '26-50mm GPU stand'. If you want something that doesn't rest on the floor of your case, look for a 'PCIe slot GPU support bracket'.
