Corsair AX850 enough or should i get the AX1200?

post #1 of 11
Thread Starter 
Just between these 2 power supplies please for my system below but with 2 of these

http://powercolor.com/us/products_features.asp?id=314

edit: oh and i plan on overclocking them as much as i can

instead of my 5770's

right now i idle at around ~225w and running 100% cpu and gpu load put me at 575w (at the socket)

Newegg got rid of their combo deal with the corsair 800D and the AX1200 so its quite a bit more money now so if i dont have to spend the money ill just get the AX850 (i almost would rather anyways because it should let me fit a 360 radiator in the bottom if i want) but i dont want my psu to be running near its max all the time

850 Watt should be fine I believe. I know it can power 2 GTX580's.
But I am no expert, see others opinion as well.

Get the 1200... you can save yourself a few bones by buying it on Amazon.

The AX850 wil allow you to SLI or crossfire any two cards, so no problem at all.

AX850 is more than enough, but if you have money to spend why not go for the top dog

The AX1200 would be completely silly. A good 750W can run that setup fine with room to spare. Feel free to get a 850W unit but that's unnecessary. And like I said, a 1200W unit would be a huge waste.

Meter shows my rig pulling 640 watts FTW with Furmark and P95 running concurrently.
Estimate 88% efficiency would bring it down to 563 watts system demand.

My AX750 yawns at the load, so I'm sure the AX850 will be fine and the AX1200 will ask you why you bought it for such light duty.

Get the AX850 because spending the xtra money for an AX1200 with your rig isn't worth it.
