Can my OCZ ModXtreme 700w Modular handle another R 7950 for crossfire?

Specs of PC:

FX-8350

990FXA-UD3

8GB Vengeance ram

XFX R7950 Core Edition

1TB HDD

64GB SSD

OCZ 700W

Any help would be appreciated.
 
depends on how much overclocking you do, I had a tagan piperock 700W, it ran my spec in my cig fine not overclocked at all. and I only have 1 fan inside my pc, my cpu cooler fan, no extra controller cards or sound cards or fan controllers or anything that requires power. and if I overclocked my cards and cpu, it would just lock up. so it depends on how many extras ya got that require power.

I decided to get rid of that psu, and got my self a corsair 1000w, its the best most future proof decision iv ever made in buying any component in my history I think, iv always gon for a power supply that has "enough" for what I need, rather than going for the full fat overkill that will run anything no matter what I upgrade to. for the price iv paid for 450w.. 550w.. 600w.. then 700w psus in the past when upgrading my system, I should have just gone for a 1000w from the start haha, could have had enough money for a third 7950 probs :D also this corsair 1000w is 100% silent. literally 100% silent, the fan doesn't even spin unless its under a lot of load, my specs in my cigs just manages to turn the fan on to its 100% silent lowest setting after 45 mins of gaming or so at full overclocks.

Also, it removed all my graphics cards coil whine :D
 
Is that PSU the one with 46a on the 12v line?

It would be tight, very tight. You can run a 7950 on 18a, and an 8350 could easily pull another 10a on top, so already with just 2 7950's and the CPU you're close to the max.
 
To give you some idea, others will come in and be a lot more knowledgeable about this.

I have a Sunflower 650 PSU.

Which runs two Sapphire 7950s in Xfire.
A I5 2500k at 4.4
P8Z68 Gen3 M/Board
8gig ram
4 SSD drives
2 SATA Drives.
3 cooling fans..

Mine runs great, was a bit worried about putting the load onto the PSU, but I have not had any problems what so ever and I have benched them hard in the past week..
