What do you think of that PSU?

Can someone also explain to me what ripple is ?
The 750W TruePower New is better than the TX850, and it costs less:

I am very confident that it has enough power.

Easily!

Tweaktown did a test with two air cooled 580s in sli power consumption for the test rig with only an ssd and an optical drive was 859 watts when they were overclocked. A little under 700 when the 580s were stock.

Those are figures measured at the wall, which mean they include the entire system and do not account for efficiency.
859W measured at the wall means 730W drawn from the PSU assuming it's 85% efficient, and 700W at the wall means 595WDC. Well within what a good 750W unit like the TP-750 can do.
