    in hindsight I wish i had gotten the 1000w but this has work perfectly. Some of my programs cause the GPU and CPU to spike together which causes a strong load.

    Low sound & reliable power, but stiff and ugly cables.

    Just few details with some cases, some screw problems and position problems in my case but ok at all.

    The quality is questionable, it gradually failed in a few weeks, very hard to troubleshoot. The computer would go completely powered off but you can boot it power cycle it again, and it would be working for hours without any problem but then as youre working on important documents, its powered off suddently without any warning. It kept on doing this for over two weeks wihtout us being able to identify thats going on. Then one day, it just went completely off, no warning, just dead.

    I dont know who at corsair decided to use these cables but they are terrible. At each connector they use about 2 inches of heat shrink. This basically means there is a 2 inch hard piece of plastic at each end of the cables that cannot bend. Essentially what happens is the cable sticks straight out from the connector about 3 inches and there is nothing you can do about it without potentially damaging the cables. This is a nightmare for cable management. Who the hell thought this would be a good idea and why has corsair not fixed this yet?

    Ive had my Rig running 24/7 with this new PSU since Dec 17th 2020 with no problems! I upgraded the cables that came with it, looks at pics, for the upgraded Corsair cables that cost $99 extra & it was so worth it. I game, web browse & media stream for hours at a time many days of the week. I currently have a GTX 1080 Video Card BUT will soon be upgrading to a RTX 3080. This PSU will be able to provide all the power I need for the devices listed below & in the future for any upgrades, I recommend this product highly. My current specs are the following.
