Review on HVVH High Power 1600W Fully Modular ATX Power Supply - Ideal for Double CPU Mining Servers and Computers, Designed for US Voltage 110V by Jeff Jones

Just built a new system. I powered it from the PSU after all the cards and cables were installed. No energy. I hope this turns out to be a mistake I made and can be fixed and not junk sold by unscrupulous companies. Fingers crossed. Edit: The PSU is fine. The motherboard I connected had a hidden power switch. The company was kind enough to help me troubleshoot and I finally found the problem.
