I was wondering what psu I would need to get. I don't know if my current one is modular or non-modular. Here's the PC I bought the summer, the CyberPower GU380. Its got a 350w ThermalTake PurePower PSU now, but I know that it won't run the R9 270x that I am buying. So my question is, what is a fair priced PSU to get that suits my needs?
