750W enough? or 850 for new build

[marktruman]

Would 750 watts be good enough? Thinking of corsair 750w modular. I won't be overclocking

Yep, 650w wouldn't break a sweat either. Shop around, more won't hurt a thing if it's the same price as a smaller unit.

Yea you good with anything above 650.

If you're not overclocking even a corsair 550w would be plenty, really.
