June 26, 201213 yr According to Palit's tech spec their Sonic Platinum GTX 570 uses 219 watts of power so a PSU providing 30 amps on the 12v rail should be more than adequate. However searching the web many suggest that a minimum of 38 amps is needed on the 12v rail. When I went to school, albeit a long time ago, 219 watts @12v = 18.25 amps, or has this now changed with inflation? I am talking about a single card not 2 in SLi mode. Advice appreciated please.
