AI Verdict
This 3.65-slot behemoth delivers dead-silent 4K gaming and dual HDMI ports for VR setups, provided your case has 348mm of clearance and you can tolerate potential coil whine.
The 3.65-slot thickness and 348mm length make this card a physical impossibility for standard ATX cases without removing front radiators or drive cages. If you have the physical space, the 2640 MHz OC mode and 3.65-slot cooler deliver 60+ FPS in 4K at 65°C.
Measure your case clearance from the PCIe slot to the front fans — if you have less than 350mm, buy the 304mm Founders Edition instead.

Chance this product isn't for you
Pros
- Runs 4.4°C cooler than the Founders Edition under full load thanks to the 3.65-slot heatsink.
- Includes two HDMI 2.1a ports alongside three DisplayPorts, letting you run a TV and a VR headset simultaneously.
- Die-cast metal exoskeleton prevents the 1.9kg PCB from flexing or sagging over time.
- Dual BIOS switch lets you drop fan speeds to near-silent levels without sacrificing the 2640 MHz boost clock.
Cons
- At 348.2mm long, it requires taking a Dremel to the hard drive cages in older mid-tower cases.
- Multiple buyers report aggressive coil whine that buzzes loudly when pushing past 120 FPS.
- The 150mm width pushes the 12VHPWR power cable right against the glass in standard cases like the Hyte Y60.
- ASUS RMA process is notoriously slow if you get a unit with the 110°C hotspot defect.
Dimension Scores
Maxes out the AD103 silicon with 10,240 CUDA cores for 60+ FPS in 4K Cyberpunk 2077.
The 3.65-slot cooler keeps core temps around 65°C, but frequent coil whine complaints drag the score down.
Pulls roughly 270W under typical gaming loads, which is highly efficient for the performance but requires an 850W PSU.
16GB of GDDR6X is plenty for current 4K textures, though 24GB would be better for heavy AI workloads.
Best For
- 4K gamers using massive full-tower cases like the Fractal Define 7 XL or Lian Li Lancool 216.
- Sim racing rigs that need the dual HDMI 2.1a ports for multiple high-refresh-rate OLED TVs.
- Silent PC builders who want to use the Quiet BIOS to keep fan RPMs under 1000 during heavy loads.
Not Recommended For
- Mini-ITX or compact mid-tower builds restricted to 340mm GPU clearance.
- Gamers who play with open-back headphones and are sensitive to high-pitched electrical buzzing.
Watch Out For
- The 348.2mm length means you literally cannot close the side panel or fit front intake fans in popular compact cases like the Fractal Define 7 Compact.
- Coil whine is a massive lottery here — you might get a silent card, or you might get one that sounds like a cicada when rendering menus at 200 FPS.
- The 150mm width means the 16-pin power cable will bend aggressively against your side panel unless you buy a 90-degree adapter.
- Some units ship with poor factory thermal paste application, causing the GPU hotspot to hit 110°C and forcing the fans to scream at 3,000 RPM.

What Buyers Say
The sheer physical size of this card catches almost everyone off guard, forcing many buyers to buy a new case or hack apart their hard drive cages. When it fits, the thermal performance is universally praised, with the 3.65-slot heatsink keeping the GPU under 65°C even during 4K ray-tracing workloads. The extra HDMI 2.1 port is a massive hit for users running LG OLED TVs alongside VR headsets. The glaring issue ruining the experience for a vocal chunk of buyers is severe coil whine that pierces through closed cases during high-FPS gameplay.
“Had to literally saw off my hard drive cage to make this 14-inch brick fit, and now it buzzes like a pissed off hornet when I boot up Diablo 4, but hey at least I'm getting 120fps in 4K.”
Common Praise
- Fans rarely spin up past 30% because the 3.65-slot heatsink does all the heavy lifting.
- The die-cast metal shroud and backplate completely eliminate GPU sag despite the 1.9kg weight.
- Having two HDMI 2.1 ports saves you from buying active DisplayPort adapters for multi-TV setups.
- Runs consistently 4.4 degrees cooler than the Founders Edition during extended stress tests.
Common Complaints
- The 348mm length blocks front-mounted AIO radiators in standard mid-tower cases.
- Loud electrical buzzing kicks in the second a game menu hits 144 FPS.
- The 150mm width crushes the 12VHPWR cable against the glass side panel in cases like the Hyte Y60.
- ASUS Armoury Crate software is bloated and frustrating to use just to change the RGB logo.
Ownership Tips
- The included GPU support pillar is mandatory — the 1.9kg card will rip your PCIe slot out without it.
- Undervolting the card to 950mV drops power draw by 50W and completely eliminates the coil whine for most users.
- The Quiet BIOS switch on the PCB is the way to go; it drops fan noise to zero without costing you any noticeable frames.
Frequently Asked Questions
Will this fit in an NZXT H7 Flow?
Yes, the H7 Flow supports GPUs up to 400mm. You will have plenty of room for the 348mm length and the power cable bend.
Does the TUF 4080 Super have coil whine?
It is a frequent complaint on Reddit and forums. Many units emit a loud buzzing noise under heavy gaming loads, especially at framerates above 120 FPS.
What power supply do I need for this card?
You need an 850W or higher PSU. Make sure it has a native 12VHPWR cable so you avoid using the bulky 3x8-pin adapter.
Is the OC edition worth the extra money over the non-OC TUF?
No. The OC edition boosts to 2640 MHz compared to the standard 2550 MHz, which translates to a 1-2 FPS difference in 4K gaming.
Why does this card have two HDMI ports?
ASUS includes two HDMI 2.1a ports and three DisplayPort 1.4a outputs. This lets you plug in an HDMI 2.1 OLED TV and an HDMI VR headset at the same time.
Buying Guide
You are buying a cooler attached to a chip, not just a chip. The RTX 4080 Super silicon is identical across all brands, so you are paying ASUS for the metal shroud, the extra HDMI port, and the 104mm fans. Measure your case with a tape measure before clicking buy. You need 350mm of length and at least 160mm of width to safely route the power cable without starting a fire.
348.2mm Length
This is the physical footprint. Think of it like trying to park a Ford F-150 in a compact garage — if your case only has 340mm of clearance, this card physically will not go in.
16GB GDDR6X VRAM
This is the card's short-term memory for high-res textures. 16GB is the sweet spot for 4K gaming right now, ensuring textures don't look muddy or pop in late.
Dual HDMI 2.1a Ports
Most cards only have one HDMI port. Having two is like having a dual-car driveway — you can plug in your 4K TV and your VR headset without constantly swapping cables.
Alternatives
If your case maxes out at 320mm, search for the RTX 4080 Super Founders Edition or a dual-fan variant. If you want to avoid coil whine entirely, look for models with over-engineered VRM phases and water-cooling blocks.
