Looking for a free psu

[amd64skater]

does anyone out there have a free psu i can have for my new system. My g/f wont let me upgrade nothing so i have to do everything behind her back. My current rig has a stock 300 watt psu my specs are on the side my gpu is demanding a bunch of power so im thing if i get a new psu i can get through a friend i can get a new gpu. I'm looking for a at least 400 watts or better for free so i can upgrade. Thank you to anyone that can help

I actually have an Enermax 420W PSU here (Noisetaker 2) that has a 20 pin connection on it. Youd have to at least pay for shipping and Im not even sure how much that is.
