I saw these two calculators but got very different results from them. I'm not sure which to trust. Any help is much appreciated.
http://support.asus.com/powersupply.aspx This one told me 550 to 600 watts.
and
http://extreme.outervision.com/psucalculatorlite.jsp This one told me ~350 watts.
Here are my build specs:
CPU: Intel Core i5 3570K
Mobo: Asus P8Z77-V
Video Card: ATI Radeon HD 7850
RAM: Corsair 8GB (2 x 4GB) DDR3 1600
HDD: 500 GB 7,200 RPM SATA 6.0
Optical: DVD-RW
Right now I'm going with a 750 watt PSU from Antec. I figure better safe than sorry.
I don't plan on overclocking right now but in the future I think I will.
