1000 W ATX 12V v2.31 Power Supply

This fully modular unit delivers 1000 W of continuous power and carries 80 PLUS Gold certification for 90% typical-load efficiency. It targets builders who need reliable energy for high-end graphics cards and multi-drive systems. The compact 140 mm chassis fits standard ATX cases while keeping cable routing tidy.

Sustained Load Behaviour

Dual +12 V rails rated at 55 A on the 12VHPWR connector and 60 A on the standard +12 V rail maintain stable voltage during extended gaming or render sessions. Active PFC and a hold-up time above 16 ms keep output clean when mains fluctuate. Six protection circuits guard against over-voltage, over-power, short-circuit, under-voltage, over-current and over-temperature events.

Thermals Noise and Power Draw

A 120 mm hydraulic bearing fan runs under smart control to balance airflow and acoustic output. Main Japanese capacitors and an enhanced thermal solution dissipate heat efficiently during normal operation. The supply accepts 100–240 V input at 50/60 Hz, drawing 15–6.5 A depending on load, while the power-good signal settles within 100–150 ms.

Questions about this item

Will the native 16-pin cable power my PCIe 5.0 graphics card without an adapter?

Yes, the included native 16-pin cable delivers up to 600W directly to a PCIe 5.0 graphics card, so no adapter is required.

Does the 140 mm length leave enough clearance for cable routing in a mid-tower case?

At 140 mm long, the unit fits most mid-tower cases and the fully modular design lets you connect only the cables you need for cleaner routing.

What protections guard the system if a rail exceeds its limit?

The PSU includes OVP, OPP, SCP, UVP, OCP and OTP circuits that shut down the affected rail before damage can occur.
