If you need a 300 Watt P.S. go pick up a cheap brand 300Watt P.S. for 30 or 40 bux and save yourself a lil bit of money, that would have otherwise been wasted on the the same thing with a Name Brand label on it.

P = IV , or Power(P) equals Current(I) multiplied by Voltage(V). And the voltage is always constant for a particular output from the power supply, this implies that a certain component cannot pull too much current while operating at its given Power rating.
So I still say the same thing, power is power, if you need 300W, buy the cheapest 300W P.S. you can find, if you need more connectors, buy splitters, and as long as you dont go above 300W you are fine.

Yup, power is power. But there are several caveats. It's like saying a car is a car, both get you from point A to point B.
Is a brand new Mercedes Benz S500 the same as a brand new Hyundai Accent? Hell no! It doesn't matter if Albert Einstein tells you "Ach mein lieben! Der both Cars!" You'd say, "Shut up Einstein; go play with some warped space" as you 'Moe-slapped' him.

Now take a switching power supply used in a PC and do the same thing. You'll notice that various brands of power supply provide varying levels of "pure DC" current. You'll notice variations in noise patterns, different amounts of bumpiness to that ideal straight line battery-provided DC current. Under load, you'll notice even more variations.
There are numerous other examples where power supplies designed to minimize component cost and those with a bias towards sound engineering principles differ.

(A: Because most of them don't have oscilloscopes. Many hardware review sites couldn't even spell "silly scope"...)
