PSU For The Following Specs?
To determine wattage, the formula V x A = W (voltage times amperage equals watts). By RK on 16 Jun. 2014 Verified Purchase Some people say 650w is useless because the wattage is too high for single graphics card systems and too low for dual. Retrieved 2014-06-29. ^ John Benatti (2009-08-01). "MTBF and power supply reliability". External power supply could send data about itself (power, current and voltage ratings) to the computer. Source
For certain graphics cards, the PSU's 12V rating is crucial. Originally, a power supply featuring "multiple +12V rails" implied one able to deliver more than 20A of +12V power, and was seen as a good thing.
