My desktop's running off a corsair cxm 750 I got off the marketplace. It's never done me wrong but As I've recently upgraded almost everything else and need an extra psu for my new file server I figured I may as well look at swapping this out. Current spec: Asus X99-S 5820k, currently stock but will likely oc a bit in future, nothing extreme. 980 Sm951 512GB Samsung evo 840 250GB Some other 250GB crucial ssd 1.5TB Samsung F3 H110 H110i GT Corsair link and half a dozen 140mm fans A dozen or so assorted usb peripherals, none particularly high power. I'd like to go fully modular if possible, so what sort of wattage should I be looking at, and does anyone have any suggestions? I also need a low end gpu for the file server; as it will also do some transcoding is there much advantage to going with a better/newer low end card, e.g. Gt610 (48 cores) vs gt720 (192 cores)? I'm assuming memory won't really be an issue.
