Hi all,

I'm just curious if getting a 750w PSU for a system that currently requires around 400w of power can be problematic in terms of longevity / power consumption?

I might SLI two 770s about a year down the road and I've added one just to check the wattage I would need and it adds up to 628w.

Is it a "problem" to get a 750w 80+ BRONZE from the get go? Thanks, as always.
