My Rosewill Green Series 630w PSU which I got 3 weeks ago from newegg has been making strange noises. Tonight, I took it out and will RMA it. Luckily I had a spare Rosewill Stallion Series 450w, so that is my current PSU. I will be getting a Radeon 7770 for Christmas next week (hehe) and know the RMA will probably take longer than a week, especially with the holidays coming up. The Radeon 7770 has a Max TPD of 80 watts, which a 450-500w PSU could easily handle. My question is, what PSU should I get instead of the Green Series? My budget will be $50-70. It will need to support an FX 4100 @4.2GHz and Radeon 7770. Will the Rosewill Stallion 450w be able to handle the 7770 until my new PSU arrives?
