Hard disks typically use < 10W, SSD's only use a few. They should not be your primary concern with respect to power requirements.

Yes thats enough for your whole system and then some if you were considering SLI with another 460 down the road.

One of my systems has an OC'd Q9550, 4 GB RAM, a GTX260 - a card with similar power requirements to yours, a Gigabyte EP45-UD3P motherboard, 3 hard drives and an optical, and a Soundblaster card all powered by a Corsair 750TX.

Running 3 instances of Prime95 to load the CPU and 3DMark06 to load the GPU, it pulls 375 watts from the wall as measured by my Kill-a-Watt meter. Figuring 80% efficiency, the system pulls 300 watts from the PSU.

So I estimate that your PSU will be running at less than 50% load.

yes 750w is way enough. i mean even a 600w branded psu can run your system.
i have a much higher system than you have i7-950 w/c is a power hungrier than i5-760 but im only running a 600w fsp everest and has no problems.
your corsair 750w is way enough.
