Okay thanks. I posted the information about my system when I started this thread. Is it possible to give a recommendation of a proper PSU, or should I take it to a local shop?
Do you know how to change a PSU and hook up harness to Hard Drives/ CD, fans etc.?
If not take it to a computer shop. Tell them you want a good Quality 80+ Certified PSU around 600 watt.
They can quickly check for any other issues as well.
