I recently upgraded to a Sentey ERP650-PS and a radeon 7850 from a hd 2400. The power supply works fine with the 2400 but on powering on the setup with the 7850 I cant boot, and the CPU fan goes on high until I power off, no error beep code. I have double checked gpu connections and the 7850 fans are working when powering on. I am using a i7-2600 cpu.

Any advice for troubleshooting?
