1200W ATX Power Supply for High-End Builds

This 1200W ATX power supply delivers high-output power for demanding desktop systems. It suits enthusiasts and workstation users who require stable, efficient energy delivery for multi-GPU configurations or heavy compute workloads. The unit is brand new and built to the ATX form factor.

Modern Standby Support with Zero RPM Fan Mode

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Upgrade from Lower-Efficiency or Noisier Units

This supply replaces older units that lack 80 PLUS Gold certification, which delivers high efficiency for lower power consumption, less noise, and cooler temperatures. The jump is worthwhile when moving from a power supply without Modern Standby support, without a zero-fan mode, or with a topology that produces audible coil whine under load.
