What it is

The be quiet Pure Power 12 750W is an ATX 12V power supply rated for 750 W continuous output. It targets builders who want a quiet, gold-efficient unit for a modern gaming PC or workstation. Non-modular cabling keeps the price down while still delivering the connectors current GPUs expect. The single 120 mm fan is tuned for low noise across typical loads.

The connector that matters

This unit ships with one native 12VHPWR cable rated for 300 W and two PCIe 6+2 pin cables. If your graphics card requires the new 12V-2x6 connection you can plug it in directly without an adapter. Builders whose cards still use 6+2 pin plugs are also covered, but anyone needing more than two such connectors will need a different power supply.

Behaviour under sustained load

80 PLUS Gold certification means efficiency stays above 90 % at typical loads and peaks at 92.8 %, so waste heat remains low even during long rendering or gaming sessions. A single 12 V rail rated for the full 750 W delivers stable voltage without rail-balancing hassles. LLC resonant topology and the 120 mm fan keep temperatures and acoustics in check when the system runs flat out for hours.

Questions about this item

How does the 750 W maximum power hold up when the system is under full load?

The single 12 V rail can deliver the full 750 W continuously, so CPU and GPU draw their peak power without hitting a per-rail limit.

What does the PCIe 5.1 12VHPWR connector actually supply to a modern graphics card?

The native 12V-2x6 cable is rated for 600 W, letting a PCIe 5.1 GPU run at its specified maximum without an adapter.

Will the non-modular cable bundle fit a standard ATX case without blocking airflow?

All cables are fixed to the unit; the 120 mm fan exhausts heat directly out the rear, so cable routing stays clear of the intake path.
