Review: A wonderful PSU, and Cheaper than comparable 1000w SFX-L PSU's on the Market! - The Many Good things: -Price point is great - there is no other SFX-L 1000-watt psu on the market for under $300 (at least at the time of writing). - PSU is powerful and is easily able to handle an overclocked PSU and overclocked GPU - even the most recent, newest GPU's are compatible like the 7900 xtx and 40-series cards (at least, at the time of writing)! - Its seriously super quiet. The Fan doesn't even need to turn itself on most of the time. That might be a problem for some but come on.... youve got an ITX build. You know its gonna run hotter than most build anyways. - Its got a TON of PCI-e connectors, all fully modular! That means that you've got many options for linking it up to that power-hungry graphics card you've been dreaming about. You can use one dedicated cable per power connector on your GPU. Im using an AMD 7900 xtx with three power connectors - each using their own dedicated cable! -Wires are NOT braided, but I think that this is actually a GOOD thing! Hear me out - Braiding equals unnecessary bulk and additional inflexibility, making wires harder to hide within the smallest of ITX build. The wires as well as connectors going into the PSU are super small, more flexible than competitor's PSU's and easy to route! The only BAD thing I encountered: I originally purchased this PSU with the intention on pairing it with the Phanteks Shift XT ITX Form Factor PC Chassis... but for some reason this was a bad combination. The Shift XT Chassis wasn't able to properly ground itself with this PSU. And as a result, any random contact with the Shift XT Chassis metal plating would result in a static shock and ZAAAP! The computer would turn itself off. This was fixed by changing the PC case from Phanteks Shift XT to a Lian Li A4-H20 - and I never experienced the issue ever again.
Review: Gold standard for SFX power supplies - This is probably the best power supply available at a reasonable price (~$160). The design is sleek and the cables are high quality and sleeved. It also includes a SFX to ATX bracket to use in larger builds, though that obviously isn't ideal. There is a zero RPM mode for the fan that essentially means the fan will stay off until needed, making your computer run quieter. I would avoid using this with high TDP components, but you can always check this using a wattage calculator. I used an older model of this power supply a couple years ago and the computer still works great. I expect this from the new CORSAIR SF750 and would recommend it, especially on sale.

### ⭐⭐⭐⭐⭐ Corsair quality all the way...
*by L***D on January 5, 2026*

I've had my last few rigs in the Lian Li 011 mini (OG version) so I need SFX PSUs. Prior to this I had the Cooler Master V850, which served me just fine for the last couple of years. However, recently I upgraded all my Corsair fans and AIO to the new LINK ones and the controller requires a PCIe power cable connection as SATA is insufficient for the power requirements. The CM V850 did not come with enough PCIe cables. Sure, I could have bought another cable but I'm actually glad I bought this Corsair PSU instead, it was definitely an upgrade over the V850. First of all, the included cables are braided and are very nice, that alone was worth it for me. In addition, the Corsair has 5 PCIe ports and includes 3 standard type 5 PCIe cables, 2 CPU cables, and a 600W cable for modern GPUs (this was a nice surprise for me when I opened the box, I didn't know it came with this PSU). That allowed me to get rid of the nVidia adapter I was using, which further cleaned up my case. All in all I'm very pleased with this PSU, its dead silent and the cables are amazing.
