Cooler MasterV850 SFX Gold ITX SFF Modular Power Supply, ATX 3.1 90° 12VHPWR|600W PCIe 5.1, 850W 80Plus Gold, Supports RTX 5080|RX 9070 XT, Customized Cable, 100mm|3.9", 10-Year

Power supplies have been annoyingly expensive as of late, but this is still my favorite for a decent price.Small, light, and easily fit into my compact build. The modular cables keep things clean, especially if you don't need SATA. One of the easiest parts I installed.The all-black looks good, although a lot of the plugs are daisy-chained so you might see an unused PCIE power or something if you don't space it right.Works with anything you could want. Plenty of CPU and PCIE power, loads of SATA, and 850W behind all that.

I've had this psu in my computer for 4 years now. Never had a single problem with it! A few years back I needed an additional pcie cable, I reached out to Cooler Master's customer service and they sent me one free of charge.It's now been thru some component upgrades and many many hours of gaming and YouTube sessions lolHighly recommend this brand as my experience has been great.

Really solid PSU, comes with short cables for SFF and worked really well in my Fractal Terra.

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.

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.

Why did you pick this product vs others?:it is a great psu but does not come with a power switch.

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!
