Summary: pretty quiet considering the output easy to install, just follow the instructions is a little big as far as PSU's go, but understandable *be sure to check your cables! being fully modular means there is room for human error in which cables you end up using to connect to your motherboard- the 8pin CPU cable vs PCI-E looks similar, but check the labels!
Summary: AX1200i in service since early September 2013 abruptly died on Oct 14, 2013 after approximately 1.5 months of home use. Self-Test Feature indicated a continuous red light. All fans were running appropriately with internals running at normal temps when checked recently. Immediately after failure, internal components were appropriately warm to touch but none were hot. No AC electrical issues (e.g. power loss, brown-out, lightning, etc...) observed.
Summary: This PSU is much better than the Antec Quattro 1200 watt unit it was replacing. It is quieter, more power efficient, and fully modular which really makes for easy and tidy cable mangement. Still running strong after 2 years, and worth every penny.
Corsair Professional Series AX 1200 Watt Digital ATX/EPS Modular 80 PLUS...
24 September 2013
Summary: corsair always makes amazing products and this one is another one . this is a great power supply. it only spins up when u turn on your system. its extremely loud only at that point besides then it is super quiet.
Summary: This power supply when i got it (but probably still is) the best power supply out it is so effecient and doesn't make a sound the fan doesn't turn on because i don't use enough power to make it hot enough. (I use about 450-550 Maxed) I was planning on getting another graphics card is why i got this even though a 850 watt probably would be just fine i wanted the biggest and best. it looks great and feels the same you can tell its high quality as soon as you touch it.
Summary: This is the BEST PSU I have ever bought. I love that it's Modular so you can customize your cables and plug in the ones you absolutely need. A great selection can be found in Corsair's website, different variety of colors and also for different power supplies. It runs my system with absolutely no problem and I'm running 2 power hungry GPU's that are over clocked (GTX 690's).
Summary: I bought this power supply for a server with 6 hard disks, 2 SSDs, and 2 DVD drives 1200 watts should have been more than enough While hooking up the last two drives, the power supply threw a puff of smoke (twice) The PC will run if I only attach 4 drives, but wont supply for 6 Why did I waste the extra money?
