SLI and CrossFire Push Power Supplies to the Limit
 

Dobro pogledajte kakvo napajanje zahtjevaju dvije mrcine u SLI/CrossFire modu...grozno: hitthewa

"512MB gaming cards in SLI/CrossFire will pull anywhere from around 15A to slightly over 20A (taking 120W divided by 12V = 10A per card) meaning that our +12V3 rail was overloaded as it has to share the power draw from the motherboard as well (which typically draws around 2 ~ 3A on its own). Since we rate our power supplies conservatively, the ST60F could actually run Kelt's 7800GTX 512MB SLI system for a while despite being technically overloaded on the +12V3 rail. As soon as the over current protection point of 20A on the +12V3 is reached, the power will automatically shut down."

Sve će se to vratit na 1 12v rail i amen:)
