I have assembled a system with the following specs: CPU: AMD FX9590, MB: ASUS M5 A99FX Pro r2.0, GPU: Radeon HD 5450, AVEXIER 16GB and SSD: CORSAIR FORCE LS 240Gb. The system had a few problems. It kept freezing at random. It also break down two 600 W PSUs when I tried to run a heavy computational program in parallel on 8 and then 6 of the cores. Do you think I need a better PSU? What power supply do you recommend?
