Hello, I've been OC lately, and my PSU is holding me back a ton. I'm thinking of getting the http://www.amazon.com/Corsair-Builder-Series-Watt-CX500/dp/B0092ML0MY but is there another one that is pretty much the same and cheaper? Such as; reliability, almost same or better performance. I'm on a low budget, but if i have to ill grab that one. Thanks!
