I haven't received it yet. She just told me today what she bought me. I went to the site. But it doesn't really say what make and model for the psu. Unless I'm not seeing it?
Call or email iBuyPower.
The only system I see currently on their site with that CPU starts out with a FX-6300, and offers a free upgrade to the 8320. It also starts out with a 400w PSU, and offers a free upgrade to a 800w bronze certified unit.
Maybe if you're lucky you can catch them before they ship it and ask your gal to have them upgrade the PSU. A 400w unit won't cut it for a decent GPU upgrade though.
On the chance that it IS actually a 500w and can't be upgraded due to time of purchase possibly not being at time of current deals, then ask them who it's made by and what certification if any.
If it hasn't shipped yet, I'd also ask them if you can have them swap to a better GPU and pay the difference. As long as it's cheaper than buying the GPU yourself, it's better on your end.
