Help choosing a power supply

[sharatmath]

Hi

My rig is
Intel Core i5 2500 (mild over clocking - may be)
Asus P8H67 M LE
4GB DDR3 RAM
1 TB HDD
1 DVD Writer
2-3 USB Devices
2 12 inch Fans

and probably ATI Radeon HD 6750 Graphics card


What power supply will i need?

I would assume you would need a 550W would be enough for a single card setup and leave you a lot of room to overclock.

IIRC, 6750s don't even need a 6pin peripheral connector, so you really don't need much at all.

Another good option:
Antec High Current Gamer HCG-520 80Plus Bronze $69 ($3 shipping)

Any high quality 400-500 PSU should be more then fine.

First of all, both your CPU and motherboard do not support overclocking. You have to rely on turbo. Your current setup can easily be handled by a Corsair CX 430 V2.
