Alright, so i'm getting a new 7770 graphics card for my birthday in a few weeks. But the required power supply wattage is 450. I have a 350W PSU. 🙁 So I was wondering if anyone could find me a cheap one that is less than around $50. I know that that is a low price, I just need a good deal or else the GPU would be useless for me. 🙁 Any help would be appreciated! Thanks.
