Antec TruePower Quattro (TPQ-1000-EC) for SLI

[adeepersilence]

'afternoon.

I am currently looking into building a gaming rig from scratch, and was wondering if the Antec TruePower Quattro (TPQ-1000-EC - 1000w) is a recommended PSU or overkill for this system:

Asus P8P67 PRO
Intel Core i7 2600-K
2x EVGA GeForce GTX 560 Ti
1x 4 GB DDR3 1333
(Case= Antec 1200 if it matters)

I'm not sure if I want to go into overclocking somewhere along the road, but I do want to get the most out of the SLI setup. I realise a 750w PSU is "enough" for this system, but was wondering if it would limit my vidcard performances at all in the high-end range of games nowadays.

Also, would there be any recommended tools to calculate these things for myself? I am not too familiar with the related physics.

1Kw will leave a whole lot of headroom.
Try the psu calculator

Use 100% TDP and 100 % System load, don't bother with capacitor aging.

750 watts wouldn't limit the performance of the cards.
