Ok to that^^.

However what about other gaming activities for more than an hour or 2. Longer gaming sessions such as 4 - 6 hours, should I also multiply by 1.5?

AMD 1100T, 2 Lightning 6970s 4 hdds etc etc.

By the calculations I'm at 700, but should I be at more, just in case?

Thinking AX 850?

the 700 already includes the "more, just in case"

Thanks!

Nice AX850 it is. I thought I would need at least a 1200 lololol.

But then again, it is OCN so maybe.....

That didnt make any sense... Clearly a 750W could run your whole system well...

only $20 difference between the AX750 and AX850 though and there is a $20 rebate on the 850 so after the rebate they are the same price

question:

i have an i7 920, GTX 570, and am looking to watercool. according to the calcs, i'm at 525W. does that mean i need to go up to 600W, or can i get by with 500W?

i'm looking at Silverstone only, since i do SFF builds and use the PP05 cables.

thanks!

First of all, thanks a lot for this guide, it's VERY helpful and I think it saves a lot of threads

Does this includes 80+ ratings in mind?
As I'm looking at something within my rig range with an additional 6870; 650W would be perfect but kind of on the limit since I also have a watercooling system and fold most of the time (not 24/7 though).
Taking a Gold rated PSU (SeaSonic X Series X650 Gold) would give me additional freedom since it's able to go past the specs; or am I not understand this correctly?
EDIT: Or a Seasonic M12II 620W Bronze would do the job; it's a 50$ difference between the 650W Gold?

Power supplies are rated for output power to the components (DC). Good power supplies that are recommended can do their rated power in spec for hours at a time, maybe a little more (but overloading them is not good). One power supply rated for 650W may require 800W from the wall to output 650W to your computer. Another may only take 720W from the wall to output 650W to your computer.

Efficiency is therefore irrelevant when looking at what you need in terms of the labeled wattage.

Seasonic M12II 620W should be fine, but if you're looking for a modular unit around that price range, generally you may as well get something else as the M12II's price tends to be a little high for what it is.

Actually the same can usually be said for the Corsair HX650, but 100 CAD is an okay price and probably close to what the M12II was?

A unit comparable to the Seasonic X Series is the XFX Pro XXX Edition 750W, for 123 CAD before rebate:
