If you are looking for a newer PSU (power supply unit) that packs a punch and can utilize more cable space, this is the one for you! Granted, the only downside is that it uses the newer micro-cut (type 5) cables, so that means the connectors that plug into the PSU is alot smaller so normal cables bought elsewhere will NOT fit. So keep that in mind. There are PLENTY of cables inside the box to even power a 4080 graphics card. Cables are a bit rigid so make sure the case you have is not a small form factor build, or you might have to consider getting custom sleeved cables! Overall, fantasitc quality and the zero-rpm fan is always a plus feature!

Great in a Cooler Master NR200P - the cables are short (as expected for SFF builds) but not too short. It worked really well and the cables were flexible enough to fit without getting in the way of airflow.

Quiet and efficient, does everything a good PSU should. Only complaint is the cables are a little too short and rigid, so it might be an issue depending on your PC case.

I got this PSU for a SFF build and never had problems so far. My main complaint is that the type 5 cables are super stiff and hard to bend unlike the cables they provided for the sf750 and sf600. You have to pay extra to get the individually sleeved cables that corsair has and its super long for a SFF. Considering returning this and getting the SF750 for their braided easy to manage cables.

I know most SFX builds don’t use this much power, but my 7900XT had some major coil whine. Replaced my 750w with this 850w and the coil whine went away.

I love this psu! I built a mini itx that infortunately had water spilled on it and killed it. I had such a good experience with the power supply(the only part on the old pc that I hand had to replace at some point) that I had to buy it again when it met its unfortunate demise. Would recommend!

Buzzes while playing games

The PSU makes a distinct buzzing noise while playing games. I couldn't figure it out at first, but I finally isolated and replicated the sound. It is most definitely the power supply.
I have a 7900xtx and 7800x3d PC. I can't quite figure out if it's normal. There doesn't seem to be a lot of consensus online. Some say it's harmless and others say it could be defective. My case sits on my desk, so it's pretty annoying to hear. It's like a fly buzzing in my ear. It's not the fan because it's not moving when it happens.
I wish Best Buy had longer return windows. I would defintely return it if I could. This is why I don't like buying from Best Buy.
