Hello,
I plan to buy new graphic card 'Gainward GTX 460 GS GLH 1GB'. My PSU is 'Cooler Master Real Power 550W (certified SLI, but i don't plan to use SLI or CrossFire)' Minimum PSU required for that card is 450W with two 6-pin PCI-E power connectors (have them). So, i really worry about amperage needed to power this card...
This PSU has 3 v12+ rails (360W max power for all 3 v12+ rails). 1st and 2nd rails are at 12A and 3rd is at 6A. That makes total of 30A (in continuity) or 48A (peak)
DOES CARD USES AMPS ONLY FROM ONE RAIL, OR FROM 2 or 3 RAILS COMBINED? Considering it has two PCI-E power connectors plus power from the PCI-E 16x port on MB.
Cooler Master recommended minimum PSU Wattage for my pc with GTX 460 included at 90% load is 439W. And right now pc in idle uses 100W with my Radeon X1650, shown by front PSU wattage meter.
Please help me,my old GeForce 8800 GTS died after 3 years maybe because of this issue and i don't want to have same fate with GeForce GTX 460.
I'm gamer, student, hardware geek, but this is too much for me. There is no one who can help me, this is delicate matter. Please help me!
