Seems the PSU is the cause to my computer switch off, after reading this review:

"This PSU advertises 650watts with 36amps down the 12v rail.
In this case there are 2 x 12v rails each one "apparently" delivering 18amps each.

Having installed this PSU in my own machine, i soon found that the computer instantly powered off as soon as any stress was put on it ( ie: by starting a game with the video card pulling power ).

Upon further inspection with a voltmeter i found that not only was this so called 650w PSU not delivering the promised 36 amps, but each rail was delivering a staggering 11 amps each.... for a total of 22amps.
This is incredibly weak for a 650w PSU and is the kind of output i would expect from a good 300w supply.

In short, if you require a PSU for any kind of gaming at all, this is NOT the PSU you want and is a waste of money.
A good quality 550w will produce 40+ amps and would be a much better idea.

NOT worth it!"



Could some please say what PSU wattage i need minimum for my rig as i want to spend the least but get the best.
MSI GTX n760
FX-8320
Gigabyte AMD 78LMT-USB3 (on its way)

Ive been shopping, here is the list of PSU ive seen to buy.
What is your opinion on the best one if there is much difference? Thank you.
(Im not sure the difference on the Corsair PSU's except the wires can be attached at your will.)
