Fully modular 1200 W ATX power supply with 80 PLUS Platinum efficiency, a single 135 mm fluid dynamic bearing fan, and eight 6+2-pin PCIe connectors
Options ATX 80+ Platinum (1200W) HX Series
The Corsair HX1200 CP-9020140-NA is a fully modular ATX unit rated for 1200 W continuous output. It carries 80 PLUS Platinum certification for up to 90 % efficiency at typical loads. The 135 mm fluid dynamic bearing fan runs quietly under low demand.
This unit fits systems drawing near its 1200 W limit, such as workstations or enthusiast rigs with multiple high-power graphics cards. Builds requiring less headroom may prefer a smaller unit to avoid unnecessary capacity.
A hardware switch selects between single-rail mode delivering 100 A on the +12 V line and multi-rail mode splitting current across eight rails rated at 40 A each. Choose the mode that matches your over-current protection strategy.

The PSU supplies a 24Pin ATX connector for the motherboard main power input and an EPS12V 2.92 connector for the CPU power input. Both must be attached for the system to start.
Yes. The fan runs in Zero RPM mode at low loads, so it remains off until internal temperature rises, regardless of whether the GPU is a modern or legacy model.
Use software such as HWMonitor or Corsair Link to read the PSU's reported input and output wattage; a ratio at or above 90% under typical load confirms Platinum-level operation.
