Phanteks (PH-P850PSF_02) Revolt SFX 850W 80PLUS Platinum, Super Compact SFX Form Factor, ATX 3.0, PCIe 5.0 Power Supply, Fully Modular, Platinum-Rated Efficiency, Silent Fan, Black

Great PSU, the cables are stiff, i hope the cables can be softer

I was slowly building an itx build in a 10 liter case. The entire community seems to agree the competitors 750 sfx power supply was the go to. Waited for ever but it was never in stock. This was readily available and 100w more capable. So far its quiet, the right size for a 10l case and it seems to have stable power output. Only con are the cables. They were incredibly tough to connect to the power supply and to each part. Sizes were shorter than typical which shows thought to the idea of an ITX psu being used in a small case, but they were still too long and tough to fold so I opted for custom cables (hard to find someone who supports this particular model - dreambigbyray did and delivered perfectly). Bought it for the power supply not the cables so for what I wanted 5/5

No coil whine, finally! And I tried many. Has a 5th power port, perfect for my 4090.

The included cables that come with the PSU are horrible, they are a pain in the ass to clip into the PSU fully or just don't at all, so you'll end up spending more money on better, custom cables that have no issue going into their slot.

So I took the plunge and picked up this PSU as I've got a 4090 and have a SFF Case. The PSU itself seems to be a decent quality. Fairly quiet and the fan only ramps up when it gets taxed, and quickly shuts off again when the power draw is at a minimal. Not very loud either and not even noticeable through my case fans. The cables are also very flexible. This is great for cable management, however might be a detriment to durability. I ended up having issues right after installing it. The S1 wire on the 16 pin 12VHPWR cable was loose and was causing some issues. My monitor kept going to black screen and I couldn't figure it out until I decided to take my system apart and check the cables and connectors. I did my best to be careful with this cable as I know there have been several issues with these connectors. I've contacted Phanteks for a replacement and they hopefully get back to me soon. Besides this issue the PSU seems to be a very solid. Unfortunately for me, the whole point of getting it was for the 12VHPWR native connection. *Edit: added a star for the prompt service from Phanteks in sending out a replacement cable.

I was building an ITX build and wanted breathing room for power, while also getting something platinum rated so I went with this. Unfortunately it was the loudest part of the build. The fan was extremely loud and I could not control the curve so it was a nightmare whenever it was drawing a lot of power. Would not recommend

The only reason I took a star off is due to the PCIE cables. One normal 6 + 2 then one 6 + 2 with a splitter. I wish it had two normal 6+2.

There are too few cables to actually connect all ports to the motherboard. There is only 1 EPS 8pin. You'd expect 2. The cables are too short to actually reach the motherboard/GPU in a conventional case. Phanteks really cheaped out on the cables and forced us to buy custom cables here. It would be good if the solution above actually works. This particular unit is not compatible with the cablemod kit with the pcie ports because there is a notch on the plug that prevents insertion into the psu because on psu side there isn't a opening even though the pinouts match. I ended up with buying extension kits from cablemod and using some spare server pcie-eps adapter . It was awkward.

Ottimo alimentatore SFX Atx 3.0 da 850W certificato Platinum. Silenzioso e con un piacevole rumore all'avvio e lo spegnimento. Si puó impostare modalità senza ventola. Preso per affiancare una 4070ti con cavo 12vhpwr diretto. Dimensioni minimamente differenti rispetto al psu originale del case NZXT H1v2; dal lato connettori, gli stessi sporgono nell'alimentatore di serie per incastrarsi con una piccola staffa sul case, questione di 3-4mm... Il fattore di forma é comunque lo stesso (SFX) e puó essere installato tranquillamente.

I've searched long and hard for a PSU that was SFX and top-of-the-line. I found it. It has a quiet fan switch that you can switch on and off. Powers a 4070 in egpu setup. Worth every penny of the price.

I have purchased this SFX PSU solely for the reason of having 12pwhr connector but I was surprised of how silent it is. The fan is not always working, only under load and it stays completely silent. PSU is one of the best in this price range.
