Recently came to the forums in search of advice for a graphics card upgrade. The result was a slew of fantastic suggestions that led me to the purchase of a XFX 7850 2gb double d I absolutely love. Now I return looking for power supply upgrade advice. Currently I'm using a Dell 525w psu. My motherboard is a micro atx (I want to note that while I'm learning about PC building, I still consider myself amateur at best) so I don't think I can get much more in the way of power, but it's more an upgrade of quality. What would you guys/gals suggest?
