I was thinking of getting a new GPU so I can play Call of Duty, TF2, and other games with my friends. I have recently run into a problem though, I don't know if my PSU can handle the 6570 (44w), so I was thinking of dropping down to a 6450 (27w) to be on the safe side. I have an OEM 300 watt ATX PSU that came with my HP P6-2103w.
So how many amps do I need on my +12v rail to run the 6570 or the 6450, because people have said you can run it on a 300 watt PSU, but never said the number of amps you need on the +12v.
Other Specs:
Pentium G630 (65w)
4GB DDR3 RAM (1 DIMM)
2; 7,200 RPM SATA HDD's
DVD R/W
The system's 2-3 years old.

Your system should be barely above 100W at most. You should be able to use a HD7730 in there.

As for "how many amps," a reasonable guess is simple: take the power requirement and divide by 12. A 60W GPU card would require ~5A.

Thanks I'll definitely go with the 6570 then, but for the amps question, I was asking about how many amps I needed on the rail, I think it might be +12v/18a or +12v/16a, I'm not sure, but I'm still good to go, right?
