debating between a 850w and a 1200w

post #1 of 13
Thread Starter 
I know its quite a big window but the rig in my sig is what I am using currently, I want to upgrade my psu because I will be going 6970 Xfire soon, as well as Bulldozer with overclocks on a majority of my cooling as well as a couple more hard drives/fans/water cooling. I want to have enough head room but I feel as though 1200 is a little overkill and I only want a Corsair PSU (AX series) and that is the two they use. That being said, how big of a PSU do I really need for all of that? I don't want to have an ineffecient psu. thanks for all the help

For that system I would recommend a 750w psu, so 850w should be the highest you should go. 1200w would be a complete waste of money.

I think the 1200 watt would be complete overkill. I would go with and 850, or even that corsair tx 950 if you dont care to much about modular. I think 850 would be more than enough for what you got going on though.

Like the others, a 1200watt is overkill... I say get it. Will make your e-peen very large.

But an 850 will be fine too.

850 all the way. You'll be in the perfect efficiency range for an 850w.
1200 is way overkill.

You could pull it off with your 650w, but if you want headroom get a 750w

As stated, 1200w is a bit overambitious.

Even an 850 gives you a lot of headroom..don't go 1200
