psu company: "Hey guys, lets put some rocks in our products to weigh them down, so the guys at the tech forums will think it's a good psu."
honestly, I know usually more expensive psu's weigh more, but just because one is heavier than the other doesn't always mean it preforms any better.
Also, it isn't even that light, I've held my brother's and it doesn't feel too heavy nor too light.
He's not turning down the advice, but since he has a decent powersupply anywho, why spend money on another when it could go to something better.
I know the thread is pretty much over, sorry.
