I'm planning to add another CLUB 3D 7870xt Joker Edition to my rig for CF. For this purpose i'm planning to buy ThermalTake Tough Power 700W 80plus.

I want to know that is this PSU good enough to support my rig or it will create bottleneck situation?

Current specs:

ASUS P8Z77-V LK .
i5-3550@BCLK Frequency: 104 and Clock Multiplier: 41 @1.135v @( 4.25Ghz max which I have seen in turbo monitor :D) .
CM TX3 Evo cpu cooler .
CLUB 3D 7870xt Joker Edition @ stock .
Corsair Vengeance 2x4G @ 1632 mhz .
1TB Hitachi and 3TB Seagate Hard Drives .
3x120mm LED Fans .
CM 550W psu.
2x Flex LED@12v .

Never did CrossFire ever .
Any advice will be appreciated. Thank You.

750w with a better price and a little headroom , the TX650 only has 2 PCIE connections.

btw my friend is selling CORSAIR TX650W that's why im a little bit more interested and he has just used it for just 2 or 3 weeks and he is giving for 50$. and for the PCIe connectors I can use 2 dual molex to 6-Pin PCIe connectors.. right??
