Psu running gtx460

Hi all,
Thought i would start a new thread on this rather than continue it on my other thread.

My system

Phenom II 965 be
wd 500gb hdd
4gb ddr3 1333mhz
asus mobo
antec 902
gtx460
xfx 650w 52a +12v


The problem is my psu seems to be arcing so it is being rma'd.

I needed my system running asap as i do work through it.

I wemt to my local shop and got a ezcool 650w

it is dual rail with 20a on each rail (40a in total), i have been looking and that seems fine to run my system but not sure on this brand as i use corsair xfx and so on.

Also the gtx460 uses 2 pci-e connectors and this has two but they are both on the same cable about 5 inches from each other, all the other power supplys i have had have them on seperate cables, two pci-e connectors on one cable? is that right or is it just a extension. It also states sli on the box for the psu, dont think that is right.

I am only going to be running this psu for about 10-14days at max, but use it for gaming

Thanks all
