Pure Power 13 M 1200W ATX 3.1 PSU

This 1200W ATX 3.1 power supply delivers 80 PLUS Gold certified efficiency up to 93.5%. It features a single high-performance 12V rail and LLC technology for stable voltage regulation. The semi-passive 120mm fan runs only when needed for quiet operation.

Check ATX 3.1 compatibility and cable needs

Verify your motherboard accepts the 20+4 pin main connector and that your case fits the 160 x 150 x 86mm form factor. Ensure your GPU requires the PCIe 5.1 12V-2x6 connector or up to four PCIe 6+2 connectors supplied. Confirm your mains supply provides 110 to 240V at 50/60Hz.

Sustained load behaviour with semi-passive cooling

Under continuous load the single 12V rail maintains tight regulation through LLC topology. The temperature-controlled fan spins up gradually to dissipate heat without sudden noise spikes. 80 PLUS Gold efficiency keeps waste heat low even during prolonged high-wattage operation.

Questions about this item

What cables are included with the BP029US and what must I buy separately?

The unit ships with a 20+4 pin main connector, one PCIe 5.1 12V-2x6 cable rated for 600 W and up to four PCIe 6+2 pin cables for high-end GPUs. No extra cables are required for a standard ATX 3.1 build.

How do I decide between the available versions or capacities of the Pure Power 13 M line?

This model is the 1200 W variant (BP029US). If your planned GPU and CPU combination approaches that ceiling, or if you want maximum headroom for power excursions, select this capacity. Lower-wattage units in the same series suit lighter configurations.

What does the 1200 W rating mean once the PSU is installed in a real system?

The single 12 V rail can deliver the full 1200 W continuously. The 80 PLUS Gold certification guarantees up to 93.5 % efficiency at typical loads, and the semi-passive 120 mm fan stays off until thermal thresholds are reached.
