I'm yust buying new graphic card. I'm yust a bit confused about watt requirement, amp requirement and PSU requirement. Let's take this card for example:
http://www.game-debate.com/hardware/index.php?gid=847&graphics=Radeon%20HD%207570%201GB%20GDDR3
Here are formula:
amp = watt / volt
So 7570 max needs are 44 wats and 20 amps and 400W psu.
I know that wattage use differ in PC parts (better CPU = bigger wattage)
But what about that 20 amps? Does that mean that you need 20 amps on 12V rail to make GPU work?
I can't connect formula with informations i have.
I will be happy to see some answers. TNX
