Re: How big PSU for HD 5770 card
Make sure your PSU has that wattage on th 12v rail. Some cheat by including the other rails in their wattage number. It'll say what you need on the label, just take the +12v amperage, multiply by 12, and there you go.
Now, AMD recommends 450w for the 57xx cards. This is usually not necessary, it depends on your other hardware. The card itself uses about 80w.
