So my girlfriend got herself an i7 3930k processor. I got her a geforce 660 for x-mas, she has a 240 gb ssd from Kingston. She has this old psu laying around and i'm a little bit worried about throwing that in with her system. She says she doesnt want to be wasteful and use it, but I had an old thermaltake and when I threw in my geforce 480 (which admittedly draws a bit more power) completely overloaded my power supply and in turn took out quite a few of my components along with the motherboard. My suggestion was to get an enthusiast series corsair 650 watt or maybe the season x series 650 watt that they have for 90 dollars on egg. She didn't really understand and didn't think it would be much of an upgrade. I told her just because it was similar in rated wattage didn't make them equal. What are you guys thinking? Can she get away with this guy or should she splurge a little. She would also like to let it be known that the psu has barely been used.
