I know this is gonna sound totally out there... but compare the weight and see which one is heavier. A quality 300watt will easily beat a cheapo 450watt.

Interesting point.

IMO (all things being equal) I would say yes.

you could always test the 450 w/ a multimeter that can place a load on the unit. You might have to network yourself to see if someone you know owns one that you could borrow.

Weight is usually a very good indicator of the quality of a PSU. Notice how all case PSU's feel hollow and a nice PSU will feel like lead?

Ya, "If it's heavy, it's quality" is more than a colloquialism. There is a substatial amount of truth to the statement.

No. No I did not. But I will from now on

Makes sense, heavier means either A) better quality parts, or B)no slacking on anything for the sake of weight?
