Deepcool is the first to offer highly affordable ATX v3.1 PSUs through its PL-D series. I have already evaluated the PL800D and the PL750D, both of which performed decently given their price tags. It is not easy for an older design to output 200% of its max power to be compatible with the requirements of the PCIe 5.1 CEM, but Helly Technology achieves that. The PL-D line consists of four members, with capacities ranging from 550W to 800W. In this review, I will evaluate the third member of the line.
