Thanks.

That's lower than I expected.

I thought maybe around 750 watts or something.

I would recommend at least 750w for specs like that, it would give you a fair amount of OC/upgrade headroom and wouldn't be too stressed. Something from EVGA or Sea Sonic would be good.

Naah even a high quality 550W is enough, your system will use around 450w~480w on max load.

550 watt is enough for any consumer system.

 

Just pick up a CX550 or TX550M

While that is true, that leaves relatively little left in terms of upgradability. Also, keeping it that close to max is probably not the best.

He is talking maximum peak combined load......

 

 

You are not gonna reach that unless you torture test it. 

 

Edit: tl;dr: 550 watts is enough
