PSU for overclocking

[JSgamer]

I originally planed to get a 750 watt powersupply for my core i7 pc. If I plan to overclock the CPU and GPU should I get a higher watt powersupply or will 750 watts be enough?

Setup:
920 core i7 (plan to overclock)
TRUE cpu cooler
6 GB ddr3 ram
1 TB HD x2 raid 0
GTX 285 (plan to overclock)
Antec 1200
Corsair 750 psu
evga x58 motherboard

I'm not too big into oc'ing knowledge but 750 seems likely to be adequate.

What PSU are you talking about because wattage means little.

Wattage does fill a requirement, but I agree it's not the only important spec.

Amperage is the key.

Will you have only one graphics card? Then that 60amp psu may work fine.
This one is a better choice for 72Amps:

If you're going to be overclocking and using more than one gpu, you should
look into the 1000watt range.

That will be fine with your setup.

That's not how you calculate the rails. Take the total watts provided on the +12V rails and divide that by 12. that will give you a more approximate estimation. With that unit, you get about 48 amps.

For now I'll only be running one graphics card.

The corsair 750watt should be fine for your use. I personally would spend the extra $20 to get the 10A more on 12v rail of a corsair 850 watt:

corsair makes the best psu's! but ocz makes good ones too and they are cheaper.

I think that has already been established in this thread... and at the moment the corsair power supplies are on sale for cheaper than ocz power supplies.

really?

Yup, $129 for a TX850 at the moment, and after rebate its only $109...The ocz 850 watt is around $140 and only has ~65 amps on the 12v rail vs 70 on the corsair.
