1200W ATX 3.1 power supply for high-end builds

This fully modular unit delivers 1200W continuous output at 40°C and meets 80 PLUS Platinum efficiency at 115Vac input. It targets enthusiasts building systems that demand a strong single +12V rail and native PCIe 5.1 12V-2x6 connectors for next-generation graphics cards.

Dual native 12V-2x6 cables and etched flat cable set

Two included PCIe 5.1 cables each support up to 600W, removing the need for adapters on compatible GPUs. The flat etched cable design improves routing flexibility, while matcha-coloured H++ connectors show a visible colour cue when fully seated. A 135mm hydraulic bearing fan and 100% Japanese 105°C capacitors contribute to quiet operation and a 100,000-hour MTBF rating.

Verify ATX 3.1 motherboard support

Confirm your motherboard implements the ATX 3.1 specification to use the low-power C6 and C7 states. The unit measures 5.9 in by 5.5 in by 3.4 in, so check that your chassis can accommodate a 140mm-deep power supply. Ensure the 100-240Vac input range matches your local mains supply.

Questions about this item

How long is the 135mm hydraulic bearing fan rated to run before it may need replacement?

The fan is part of a unit with a minimum MTBF of 100,000 hrs, so the bearing is designed for very long continuous operation.

Which protection circuit activates first when the +12V rail is pushed to its 1200W limit for extended periods?

Over Power Protection (OPP) will trigger if total output exceeds the rated 1200W, while Over Temperature Protection (OTP) engages if internal temperatures rise above safe thresholds.

What is the typical noise and heat output when the supply runs at full load all day in a 40°C ambient?

The 135mm hydraulic bearing fan is designed for ultra-quiet operation; the unit delivers 1200W continuous at 40°C with 80 PLUS Platinum efficiency, minimising waste heat.
