Cooler Master V750 White SFX Gold ITX SFF Modular Power Supply, 750W 80Plus Gold, ATX 3.1 | 90° | PCIe 5.1, Designed Ready Nvidia RTX 5070 Ti | AMD RX 9070 XT, Customized Cable, 100mm|3.9", 10-Year

It's a modular power supply with good efficiency, and has good ratings for the power supply purchasing guides I read. No issues on a Ryzen 5 9600x and rx9070 xt. Fits well in an ITX case, haven't noticed any issues with it at all.

First off, clearly no one complaining about these cables has dealt with other SFX or SFX-L PSUs with worse cable stiffness like the SIlverstone SX1000. I've had plenty a PSU with worse cables, these were surprisingly easy to work with in a SFF build. That said, I do wish the GPU cables were a bit shorter since there's three individual cables I am having to hide 2/3 length for in my case.Too many actual SFF cases that "support SFX-L" really don't in any usable way (looking at you Lian Li Dan A4-H2O, Phanteks Evolv Shift XT, and Hyte Revolt 3)... You end up with the cables absolutely SMASHED against the PSU trying to get a higher wattage SFX-L in there.Enter this beauty and despite having the connectors protrude a bit more than some SFF PSUs, it's a dream by comparison. I had enough room to actually put the cable managing cover back on in my Hyte Revolt 3 and keep from having cables push my GPU at an angle a bit in the case.The noise is totally fine, I don't hear it really at all at idle or load. I DID have a coil whine issue when my computer was powered off, actually, but after some searching and adjusting BIOS settings for ErP/S5/whatever power saving settings you have options of that went away entirely. Now it stays silent and operates wonderfully.If you have a higher power SFF system or want to save space in the case, this thing is great and I'd absolutely recommend it with the same level of quality as things like the Silverstone SX1000 or 850R, Phanteks Revolt, or Corsair SF750. When on sale this was ~$20 more than those and was a no brainer for the additional headroom and 10 year warranty.

Like any power supply, and I have had lots of them through my computer building years. Some good and some were terrible. I had three higher end corsairs fail right out of the box's during testing. The first one lit my board on fire before I started getting smarter. So ya never know right? This mighty little 850w fired right up, the testing mod says it is hitting at 110ms boot up speed which is at the highest end of the spectrum. May be due to the smaller caps they are using? My very first water-cooled mini ITX build so a small form size supply is crucial. I did my homework before ordering this one and time will tell how well it functions after I run it for awhile. Sadly my Mini ITX board is bad (turns out someone substituted a used bad board in a new box, yeah it happens to other people also). So this will sit a little longer before I can review it properly under load. All I have done so far is power up my water pump circuit and the fan hasn't come on yet. All I can say is the build quality is top notch!

I wish the cables were a bit smaller, but they're easy enough to manage, even in an SFF case

TL;DR: Do yourself a favor and buy the Corsair SF1000 instead.I bought this PSU admittedly after not doing a lot of research. I saw that it was a >1000w SFX PSU from a major brand and kinda assumed it'd be fine.It took about 30 min after finishing my build to realize my mistake.This PSU was by far the loudest component in my build at load, which included a 9800x3D cooled by a Nocuta D15, an AMD 7900xtx, 2 140mm fans and 4 120mm fans.That alone would be fine - at load, I expect my PC to be a little noisy. But what ultimately led me to look at a different PSU entirely was the idle noise. The fan in this POS runs CONSTANTLY, and is incredibly noisy.I replaced the V1100 with a Corsair SF1000, and it is DEAD silent at idle because it has a zero RPM mode. Shockingly, it doesn't even turn on very often with my 9800x3D.Sadly I couldn't even return this because I took a couple of months to accumulate all of the parts for my build and by the time I had it installed, the return window closed. I feel BAD about re-selling it on the used market knowing that I'm jumanji-ing some poor unfortunate soul who ends up with this absolute howler.If I could give it zero stars, I would.
