PSU for my gaming rig

[Donleo17]

im looking into a new power supply to power my gaming rig.
currently i have 8gb ram
3570k
560ti
3 HDDS
i may also get another 560 ti so i want to get high enough wattage for sli

i found this one and was wondering if it was any good
http://www.amazon.co.uk/OCZ-OCZ700MXSP-UK-ModXStream-Power-Supply/dp/B001R28LRY/ref=sr_1_2?s=computers&ie=UTF8&qid=1349460766&sr=1-2

and how much wattage would i need to sli a 560ti?

For the same price this is much better:
Antec Truepower New TP-750 (£70 @ Scan)

Better because it is more efficient, modular, longer cables, more cables, better built, uses indy regulation (vs group on the OCZ), longer warranty (although I don't believe Antec are based in the UK, whereas OCZ do have a base). It also has a better +12V rail distribution compared to the OCZ MXSP700W.

For a system with two GTX 560 Tis you need a PSU with four PCIe connectors, which the OCZ MXSP700W doesn't have.
650W/~50A combined on +12V rail(s) is more than enough for a system with two GTX 560 Tis.
