Generic "Ask the Experts" HOW MANY WATTS GAME.

post #1 of 16
Thread Starter 
In all seriousness, I've been back and forth between a 850w and a 1200w, and I'm scared of:

A) the 950w not being enough at load,
and
B) the 1200w not being very efficient idle/50% load which is where I'll be at most of the time.

I don't plan on OC'ing above 4.3ghz (in turbo, so..)

-i5 2500k
-Corsair H70
-2x 6970
-16gb RAM (I know I know, like 2w difference)
-240gb SSD
-Crap tons of fans due to the HAF X, dunno if it makes a difference, most will be on the mobo controller
-Maximus IV Extreme board
-Titanium HD sound card too, don't know if that'll affect it much
-24x DVD-RW, shouldn't pull too much power?

I hate not knowing how to calculate this out without the help of an online calculator too, if anyone could graciously explain in detail.


EDIT: Btw, the PSUs are both Professional Series from Corsair.

A good 850 watt unit such as the Seasonic X-850 would do well IIRC

A good 850 would be more then ample, heck a decent 850 will work fine. I had a raidmax 1000 running my sig rig just fine

a really good 750 would likely be just dandy as well

Good 750W will work just as well as a 850W. But if you want that little assurance go with a 850W.
