I first built my PC in August 2011, which consisted of fairly low end parts and a 450w generic £5 psu.
However, I upgraded my GPU and CPU (about 170w extra load) in March 2012
Then the problems started, constant BSOD's, Unstable OC's and stupid voltage ripple out of ATX12v Regulations.
Under load the CiT 450w psu would drop from a measly 11.6V at idle to 10.8V under load, oh dear.
I was just playing a game and the pc just shut off, not happy (September 2012)
10minutes later, fire up PC and smoke.
I purchased the XFX PSU to replace it and boy was I impressed.
Good sleeving, Nice looking PSU, 44A on a single 12v rail from a 550W!
6 Months on, PSU is very quiet (under a 400-450w load) (Phenom X4 955 OC @ 4.0Ghz and Radeon 6850 OC at 950/1100)
+12V - 12.1 - 12.2V
+5V - 5.09 - 5.14V
+3.3 - 3.35V
+12V - 11.98 - 12.05V
Holds its 12v very well even under a fair load, great psu.
All in all, I spent £30 originally on Case + PSU, bought this for £50 and a new Zalman Z9 Plus to go with it totaling with express delivery @ about £100
Awesome Job XFX (also have 2 of your graphics cards:)
