V1100 SFX Platinum ITX SFF Modular Power Supply, ATX 3.0 90° 12VHPWR|600W PCIe 5.0, 1000W 80Plus Platinum, Supports RTX 5090|RX 9070 XT, Customized Cable, 100mm|3.9", 10-Year

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.

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.

This is a good PSU, looking at reviews I ended up returning it. For the price there are better options for the price in 2024. That said, if you have your heart set on this or already have it, it is not a bad choice.

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!

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.

After a couple weeks, started having random black screens with no warning, and fans would go full speed. Classic sign of hardware issue. Swapped a whole bunch of parts out to test. Got the PSU and swapped it with another unit. No more black screens, and find that the new PSU supplies draws more power from the wall seen on a kill-a-watt. So some defect in the PSU causing it to deliver insufficient power, or some other power delivery issue that caused the computer to crash repeatedly.Inquiries to Cooler Master for an RMA (< 6 months old) have been ignored (3+ weeks). Amazon won't do anything about it since it is past their return window.It looks like it is now no longer in stock, which isn't surprising since it was probably a faulty design or component.

yes the cables are annoyingly stiff, but you simply can’t pack this much wattage and efficiency into an sfx unit for 200 bucks without atleast a couple corners cut. with a 10 year warranty i have full confidence that i wont need a new psu til i have children
