What Power Supply?

[dfedders]

What are some decent power supplies for an i5 750. I'll probably grab a Gigabyte UD3R motherboard. I'm thinking of also getting an ATI 5850 card. I will do some overclocking, but nothing extreme.

What is a decent, yet not crazy expensive, power supply?

Thanks. So 450-550 is enough, even for moderate overclocking? No need for a 700-750 watt?

Both of those reviews are for the LS not the GS

GS is made by Huntkey and it is rated at 25C and Peak output.

The LS-450 is a better PSU than the GS-550 IMO.

Also the OEM of the Corsair VX550 is CWT not Seasonic

No way you need 700W for the setup you suggested, even with heavy OCing.
