Cooler Master V1100 SFX Platinum 1100W Fully Modular Power Supply – 80+ Platinum Certified SFF PSU, ATX 3.0 & PCIe 5.0 Ready, 90° Angled Cable, Low Noise, Small Form Factor ITX PSU, 10-Year Warranty

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.

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.

Not as loud as some would have you believe, however, the cables that come with it, suck, point blank. It doesn't come with any 90 degree bend cables, and the wiring is very difficult to bend to shape to fit easily in the case. Apart from that, works flawlessly, provides consistent power, and was very very easy to install/connect to the motherboard. 1100w in a small form factor like this is incredible.

The noise of the fan is not nearly as noticeable as some people have mentioned in their reviews. The cables are worthless though. I ordered custom cables and to better manage the cables and the psu has been without issues for a few months now. I have it driving a 5950x and a RX 6950 XT without any issues.

Only "con" i could find is that the fan is active 100% of the time but it's not really noticeable at a reasonable distance(4ft from me on the desk)

It’s powerful, obviously at 1100w in sfx form is fantastic. That’s where the pros end. First it’s always running, no matter when even in sleep mode, it’s the loudest part in my whole sff build. Second the connections actually protrude so it’s bigger than an actual sfx psu, so clearance can be an issue and it was in my case. I had to cut my psu shroud for it to fit. And third for $250 you don’t even get sleeved cables. I’m so sick of companies selling cheap cables especially for this price range. I would only recommend this if you really need this much power and need a sff psu!

it is a great psu but does not come with a power switch. had to provide my own. UPDATE* works very well with the added power switch. np

I bought this PSU first for a while and didn't install until all the pieces come together until about 6 months later. 9800X3D was very hard to come by at the time. For the first 3 or 4 months after the build, it was working fine. I don't actually have noise, coil issues like many do. However, last two months or so, PC started acting up just like a few reviewers on Amazon complained. Symptom is that you get a random black screen and then you hear all full fan blast noise -- until you have no choice to manually shut it down. So, I reseated the power plugs and that fixed for a while but issue keeps coming back. This PSU being SFX that naturally goes into smaller cases, it would be tedious, inconvenient, harder to replace compared to mid or large PC cases. I thought Cooler Master was a brand that I count on to have no issues like this but I was wrong. And I'm two weeks over since 1 year warranty that I'm SOL for replacement or support.

J' ai du le retourner une fois comme j'avais obtenu un Power supply ne fonctionnant pas, mais le nouveau fonctionne à merveille.

My unit was DOA. Couldn't power on my new system and couldn't power on my PSU tester. I cross checked that my PSU tester works with a working PSU. I'm glad this PSU didn't kill the system that I hooked it up to. You folks should invest in a PSU tester that you have confirmed to be working. It will save you a lot of troubleshooting.

After reading horror stories about 100mV of ripple on the 12v rail I decided to return it. I was too scared to hook it up.
