1600W ATX power supply for high-output builds

This unit delivers 1600W of continuous ATX power for workstations and multi-GPU systems that demand sustained headroom. It targets builders who need a single rail capable of feeding power-hungry components without daisy-chaining cables.

80 PLUS Gold efficiency with Zero RPM fan mode

Gold certification means less waste heat and lower running costs under typical loads. The resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight while suppressing coil whine. At low and medium loads the fan stops completely, leaving the system audible only under heavy demand.

Modern Standby compatibility for instant wake

Modern Standby support allows the PC to enter and exit ultra-low-power sleep states in seconds rather than minutes. This changes daily use by keeping network tasks alive while the machine appears off. No extra software or accessories are mentioned in the specifications.
