hell yeah it can! I had a modxtream powering a q9450 a gtx 260 with a 9600gt for physx, 6Gb's of ram, and a 250GB hdd. This thing can easily power that stuff man. Oh, and mine was the 600w one too, so dont sweat it bro

Really, because I heard I need 40a on a 12v rail for one XFX! The specs say 25a, but I am very new to all this

On the back of my XFX box it says 600w needed, but on a certain review I saw that I had only 550w total with all my 12v rails.
Still waiting on more info, and thanks for posting +rep

yeah, im not too technical when it comes to psu's either. The thing i see when im picking a psu is whether it is over 80+ certified and preferably modular. I never listen to the power req. on the box, that is rubbish. I remember my 9600gt's box said it needed like 500w

lol. Trust me man, you are fine here, most modern psu's like this can handle some pretty high end cards, just remember that your pc will use much less than 700w at max load, so i would not see any issues arise.

i am purchasing in 1 hour, but still waiting on a response
i know you guys said 40a for the whole system so add 10a for cf <normally>
but what about 3x 5770s? can i do it, mana to use a cpu cooler..and maybe OC a wee bit?

and i cant even use 3 right? cuz i have only 2x 12v rrails?

Rails have nothing to do with it. You are fine, 3 will work.

It depends where the OCP is actually set at. Sometimes it isn't anywhere close to what is listed. The two PCIe and the molex connectors are on the same rail. If you were to use molex adapters to power a third 5770 they would all be on the same rail (apart from what it draws through the PCIe slot which is on the other rail). From what I have seen a 5770 will draw ~80-90W. I'd guess about 30 of that is through the PCIe slot. That would mean ~150-180W through the PCIe connectors on the second rail. With a limit of 25A there shouldn't be problems with the OCP tripping and the PSU shutting down, assuming you don't have a ton of stuff hooked up to the molex and sata connectors. But then I personally wouldn't run three on the 700W ModX Pro. Based on the 12V capacity (46A) and it's performance under higher temps I am more comfortable calling it an acceptable 600W. With a quad and some OCing involved I would stop at two 5770s, but it would probably run three.

hmm, i do want to oc my 965 125w and my g.skill ripjaw 1600 4gb ram
so what do you recommend
the asus formula III for 2 or a gigabyte

Here's the psu selector chart from OCZs site.
http://www.ocztechnology.com/support...pply-selector/
Based on it if you run 2 of those cards you sound be fine because that card only requires one 6 pin pci-e connector to run it. But it doesn't even show one of there psu's running 3 cards until you get to the Z-Series psu's. In my opinion I wouldn't run more than two on it. It may be able to get the job done but I'd rather be safe than sorry. Power failure isn't something you want putting your rig down. Besides, even the card it self recommends a good 600 to 800watt psu just for running in crossfire. Unless you go Antec or PC Power & Cooling, I wouldn't go under 1000watts for running 3 cards. Just my opinion. Hope this helps.
Did I mention that I purchased that same deal during the black friday sale?!
