Cooler Master V550 Gold V2 PSU, UK Plug - 550W, 80 PLUS Gold, Fully Modular, ATX Power Supply Unit, Quiet 135 mm FDB Fan, Semi-Fanless Mode, 10-Year Warranty - Black Edition

I returned this item and still I don’t receive my money from 5 April until now

I see that a lot of the reviews here lumped together mentioning lower capacity units, 750W, 650W 550W etc. Just to be clear this review is only for the Cooler Master V850 Gold V2 PSU.This is a good power supply, which is able to support power-hungry graphics cards up to an RTX 3090 Ti. It arrived well packed, the box contained the PSU, which is fully modular with a separate bag containing all the cables you would need for a normal build, they are are either fully sleeved or the flat ribbon type. Finishing the contents is the AC input cord, some mounting screws and a good user manual.It's nice to see that this PSU has three PCIe cables, which you can use in super high-end graphics cards with three PCIe sockets. Please note that it is best to avoid using both PCIe connectors of the same cable in high-wattage graphics cards like the Nvidia RTX 3080 and RTX 3090, I would actually avoid doing so with any card. If your GPU has two or three sockets then you should use two or three cables and not one cable with both connectors.It was disappointing to find that the PCIe cables only come with double connectors on them, I was trying to go the extra mile with my cable management for my build. My Strix RTX 3070 needs two PCIe cables and this now means that I had two extra connectors hanging down doing nothing, even after using cable ties to tidy it up a little, it still didn't look good. At this price range it would be nice to see Cooler Master include some single connectors as well as maybe some cable caps too.I wasn't going for a super quiet build on purpose but my choice of a BeQuiet CPU Fan and Fractal Case Fans were were certainly taking me that route and this PSU did too. It runs very quiet at idle and even under load it is not at all noisy.If you are looking for actual test results then there are full reviews on tomshardware and tweaktown which cover those, which are overall very favourable.This seems to be a high-performance PSU with quiet operation and good build quality. There are other cheaper ones out there but not many, if any are supported by a hefty ten-year warranty.

UPDATE - after posting my review, the price doubled to over £80. Still reasonable value, but certainly not the bargain it was.I build a lot of PCs. Many are just basic office workstations, so they don't run games or have to perform any other cpu intensive or graphics intensive tasks. The PC I'm building at the moment is intended as a music streamer for my hifi.What I value above all else is silence. Not just quiet, I mean absolute silence: passive cpu cooling, solid state storage, and the hard part: silent power supplies.I couldn't believe this was a modular, silent PSU at a reasonable price. The white 550W version is £30 cheaper than the black one. (Seriously? People pay nearly double the price for the right colour PSU???)The PSU comes in a sturdy box with foam padding. Both the PSU and cable pack have further cloth bags. There's the usual selection of cables which are a good length and look well made. There's also a pack of cable ties and screws and a UK 3 pin plug.Plugged it in and it just works, and the PC is what it should be, silent.I'm so impressed I've just gone and ordered another one for my next project.

Had this in my system with a Ryzen 5800X & RTX 3070 for over 6 months now and not had one single issue with the PSU, would buy again for sure.

I've had my 550W PSU for 18 months now, and performance wise it has been great - no issues whatsoever. When I bought it, I didn't have a graphics card, due to prices being crazy, so my PC's power consumption was minimal - unfortunately, this meant I didn't notice my PSU's issue until too late. As soon as I got my graphics card, and started playing any sort of moderately demanding titles, I realised that once the power consumption of my system reaches a certain threshold (around 160W by my reckoning), the power supply fan turns on and becomes ridiculously loud. My system is fairly quiet, making this even more noticeable, but the difference is night & day regardless - the noise floor in my room is around 28dB (pretty quiet), but as soon as the power supply fan switches on (all other fans remaining off), this jumps to 54dB (about the same volume as me talking). For reference, with all 5 of my case & CPU fans at maximum speed, the volume is 47dB. Maybe I just have a faulty unit, I don't know, but it is really unpleasant to deal with, especially when playing games whose power draw lies roughly on the threshold, meaning the fan is constantly ramping up and down.
