Our buying advice pertaining to PSUs has fluctuated over time. In light of significant energy efficiency improvements made by manufacturers of CPUs and GPUs, where a high-end system chews through no more than 300W, we have wondered at the need for 800W-plus supplies.
Yet the nascent craze of coin mining has brought high-wattage, high-efficiency PSUs back into the spotlight. Ideally such a supply would have a long warranty, 80 PLUS Platinum efficiency and a roster of fully-modular outputs that cater for every need. Antec believes it has such a supply in the High Current Pro Platinum (HCPP) 850W.
