I almost RMA'd a perfectly good motherboard due to two faulty power supplies. Had intermittent system shut downs oftentimes while the system was idling. This was with a Corsair AX860I which would trip and shut the system down. Swapped out CPU and then GPU. Still had the same issue. Then swapped PSU out for Corsair AX1200I. Same problem. Thought I had a bad motherboard. Tried another motherboard. Same issue. Hard to believe I had two High end PSU's fail. Swapped in cheap 550W HEC PSU I had laying around. Problem solved. Ordered this PSU and system has been running fine with no problems so far. Runs quiet and I like that the fan doesn't stop completely just turns extremely slowly. My water pump is the noisiest component in the case now. System specs - MSI B550m Mortar / Ryzen 9 3900x / Nvidia 2070 Super / 2 - 1TB M.2 drives / 1 - 1TB WD HDD / 2 - 200GB HDD - Water cooled Swiftech 240mm radiator w/MCP55x pump / 6 - 120mm RGB fans / 1 - 200mm RGB fan.

Great PSU.. dumb quiet I installed it in my Montech Air X case. At idle I don't hear and coil wind what's so ever.On full load I hear my GPU fans more then anything. This bequiet PSU replaced my thermal take 750 smart fan which was getting loud under full load. As for the cables supplied that comes with this unit. I prefer ribbon style cables mainly for the look the 24 pin and 8Pin CPU plug. I cant really complain as for ease of cable management. The cables are nice and stiff so I recommend before installing the ones you need give them a little work out so you minimize any unwanted damage to the parts your gonna be installing them too.I recommend this PSU for anyone attempting a quiet PC build.

This has plenty of power to drive my Intel i7 CPU and an NVidia 4080 graphics card and it has all the power connections I could need for a gaming PC. It's so quiet I can't really hear my PC start even in a very quiet room. It's much quieter than the air ducts for the furnace in my house. I'd definitely buy this power supply again if my PC were stolen.

I am a stickler for having a quiet PC. I bought this power supply because it had great reviews and it did not disappoint. Very easy to install. Comes with all necessary power cables. And most importantly of all for me is that it’s extremely quiet. I highly recommend this power supply to anybody that wants to build a quiet computer.
