So, I'm thinking on getting a new graphics card soon, my humble GTS 250 really can't cut it at 1920x1080. I'm thinking of something like a 6850/6870 but my PSU is only a 400w, do you guys think that'll I'll need a higher wattage supply for running one of these cards?
Depends what quality the PSU is. It is a decent seasonic one or Corsair it should be fine for anything along the lines of 460GTX/6850/6870. EDIT: Getting ninjae'd too much lately
Although i love the CX400 and had a few serve me very well, i think on this occasion you need something a bit bigger. Maybe a VX450W or VX550W. They are about £55 and £65 respectively on Scan.
If you have two spare molex connectors just just a molex(x2) to 6-pin adapter. I do with my 400W Corsair
me too and ive read an article here and there that show why it's a bad idea. but on a single rail psu it's probably ok...
