Your problem is the power supply already almost at limit. Once you overclock means you are pushing even more. Minimum requirements for 4890 is 500W.

Get a higher capacity PSU for overclocking.
eh, who said it's "MINIMUM REQUIREMENT"?http://ati.amd.com/products/radeonhd4800/r...ments-4890.html

check the site carefully, it says "500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended"
see, RECOMMENDED. meaning you can settle for something less than that because they (AMD, or the company who holds the product) will surely state a rating that gives MUCH more headroom than the minimum requirement.
and the stated RECOMMENDED would surely be covering 500 non-true power PSU as well.
so IMO ts punya ST56F would be enough.
I'm using Odin GT 550 with E7200 @ 3.6ghz with +0.25vcore AND a GTX295 (previously HD4870x2), which i think the graphic card alone already beats the HD4890 / X3 + OCing total.

blindbox, how did you derive the OVERHEAT theory? it could be just some bad components.

Don't forget about capacitor aging. You will get less power supply after every year depending on how you use your computer.
btw his PSU not even 2 weeks old.

EDIT: Well, one to one exchange is not possible after more than a week(it's now 8 days, sucks).
