Following a hopefully thorough investigation, the Huntkey Enterprise Group has concluded that 900W is the "most useful and suitable" wattage for a power supply used by gamers and enthusiasts. As a result, the company has constructed the X7, a 900W modular PSU that puts the emphasis on four things – efficiency, enhanced performance, effectiveness and environmental friendliness.Efficiency is the biggest concern of most enthusiasts. How does Huntkey X7 900W PSU measure up?
"Interleaved PFC": It turns one traditional big PFC into two smaller CCM PFCs that operate in turns. By doing this, it reduces the ripple currents both of input and output and current stress on PFC FETs and improves the PFC efficiency by one or two percent. "Phase-shifted ZVS full bridge": Lots of PSU on the market now works by traditional "hard switching" topology such as double-forward or half-bridge. "Soft switching" topology such as in the Huntkey X7 900W normally uses high efficiency server power supply and telecom power supply over 3000W to realize up to 90% transfer efficiency.
