hi

im ready to upgrade my sig i wanted to add a i5 2500k and a hd 6870 but not sure if my power supply is good enough its a corsair 400w cmpsu-400cx

if its not good enough would i be best of getting a hd 6850 or just dropping the core i5 and going with a hd6870

thanks in advance

I would say you should be able to power up, but if you're oced and gaming you might run into some shutdowns.

(i got around 390ish watts OCed....on a different calculator...with a few extras)

I think it'll be enough with a 2500K and a 6870.

You'll need to use a pic-E adapter as that psu has only one pci-E cable.

You guys are so brave...I guess I've ran into "under powered" problems before which makes me cowardly and skeptical... however it's good to know I can do more with that PSU than I thought (i have the same one in my htpc...sorry for the thread jacking)

your i3 SB is as powerful as the PIIX4s. i think you should just get the 6870 and a recommended psu of 500W.

going with the i5K - you will need a better cooler, a better gpu, a better mobo, a better . . . just wait for ivy or the actual performance results of BD and decide to upgrade.
