Hey...Sarah is Back!
Hello . I will to purchase a Brand new Video card ( ati Radeon 4870 ) . Will my " old " Coolermaster 400W psu do it ? I am running on a mid end PC : AMD Athlon X2 4200+ Oc ed to 2.7 GHZ 4x1 GB Transcend DDR2 memory ( 800 Mhz ) Nvidia 8600GT Biostar NF-560 AM2 motherboard So the question is that will my Ati work with a 400 W coolermaster Psu ??? I made a PSU calculator , and it showed that i need 341 W at 100% load . I dont want to buy a new PSU , cuz i live in a *** country ( peoples here arent that rich )
Yes it will be fine but make sure you have 2 6-pin connectors.

You should be ok, I have run a 4870 on a 400w psu before with no issues, and it was a lot worse than any coolermaster. Just dont start running furmark etc 'to test' and i'm sure you'll do fine.
