So for the build listed above, I have spec'd out a 650 watt PSU, which I think may be overkill. The newegg.com calculator doesn't provide estimates for the 7870HD GPU.... I ran some calculations in Excel using estimates from Scott Mueller's upgrading and repairing PC book and came out with a worst case number of 582 watts (I chose high for all estimates).
Couple of questions:
If the power supply is oversized and the components don't draw the full amount does it still waste power?
Is it ideal to have a smaller supply to the system?
Can someone describe the whole bronze, silver, gold, etc certifications?
Thanks for any input!
