Corsair SF750
Reddit take
AI summary of the Reddit excerpts below — not a quote
The Corsair SF750 is widely regarded as a gold-standard SFX power supply, frequently praised for its high build quality, 80+ Platinum efficiency, and premium braided cables. While it is a top choice for small form factor (SFF) builds and capable of powering high-end GPUs like the 7900XTX, its specialized design means cables are intentionally short, which can be a significant drawback in larger cases.
Pros
- High build quality and long-term reliability
- 80+ Platinum efficiency rating
- Individually sleeved, braided cables are flexible and easy to manage
- Strong performance capable of handling high-end CPU and GPU combinations
Cons
- Cables are very short, designed specifically for small form factor cases
- Higher price point compared to standard ATX power supplies
- SATA connector spacing can be awkward for reaching multiple drives
Caveats
- Using this in a standard ATX mid-tower typically requires purchasing cable extensions for the motherboard and other components
- One user reported system blackscreens with a unit from 2020, though most feedback remains highly positive regarding longevity
Best for
- Small Form Factor (SFF) and Mini-ITX builds
- Users who want easy cable routing without the bulk of plastic-sleeved cables
- High-performance compact gaming PCs
Avoid if
- You are building in a large ATX case and do not want to use cable extensions
- You are on a strict budget and do not require the SFX form factor

PSU: CORSAIR SF750 - $160
The SF750 is a good quality unit.
As others have mentioned, you've selected an SFX PSU meant for small form factor (mITX cases), not large ATX cases like you currently have. ... However, using extensions cables isn't an issue. I have a Corsair SF750 that I had moved from a compact cast into an ATX mid-tower. I've been using universal cable extensions for the motherboard connections for a couple of years now without issues. So it's perfectly fine, but if I were starting out new, I would get an ATX PSU.
I ran a 7900xtx and 13700K on an sf750 and that was totally fine. Gaming components are only getting more efficient
PSU - Corsair SF750
That should be fine then---get the GPU and if need be, a CPU. A 5700x or 5800xt would be a good upgrade and they should be in the $150-$175 range (hopefully still for that price).
I wouldn't have needed to get a new power supply today if I had just paid the few dollar extra for the SF750.
Components in question: GPU 7900XTX reference undervolted to 1100mV, CPU 9700X, RAM 32G DDR5 (grabbed before the RAM price hike), PSU - OLD Corsair SF750 from 2020. ... recently I've been experiencing complete blackscreens in the middle of a game session - system does not CTD, instead just a blackscreen and nothing happens next.
I am not sure how to rule out (check) PSU failure so I am attaching some graphs from HWinfo during gaming and I have no idea if they are good or bad. Seems everything is a bit underpowered? PSU: Corsair SF750
The cables that come with it seem….incredibly short? I ordered a new motherboard cable extension as that didn’t reach, but the hard drive cables are confusing me. Only the very last sata connector can reach a hard drive the rest are so ridiculously close to the PSU.
