Pure Power 12 650W ATX 3.1 PSU

The be quiet! Pure Power 12 650W is an ATX 3.1 compliant power supply with 80 PLUS Gold certification. It delivers up to 650 W from a single +12V rail and includes a native 12V-2x6 connector rated for 450 W plus two PCIe 6+2 pin cables. A 120 mm fan and LLC topology keep operation quiet and voltages stable.

Suitable for mid-range builds with one modern GPU

This unit fits builders who need a single 12VHPWR connection for a current graphics card and do not require modular cabling. It is not for systems that demand multiple 12VHPWR connectors or fully modular cable management for a clean interior. Buyers planning dual high-end GPUs should look elsewhere.

Steady output under continuous load

The single 12V rail maintains consistent voltage regulation during extended gaming or rendering sessions. Gold-rated efficiency up to 92.7 % reduces waste heat, allowing the 120 mm fan to spin slower over long periods. Over-voltage and overload protections engage if limits are exceeded, preserving component safety.

Questions about this item

What motherboard power connector does this 650W unit require to turn on?

It uses the standard ATX 12V 24-pin main connector and a 4+4 pin CPU power connector, both permanently attached because the PSU is non-modular.

Can the included 12VHPWR cable run an older graphics card that only has 6+2 pin sockets?

No, the 12VHPWR cable is keyed for PCIe 5.1 GPUs; for older cards you must use the two separate 6+2 pin PCIe cables that are also fixed to the unit.

How do I confirm the fan is running quietly after I build the system?

The 120 mm be quiet! fan spins at low RPM under typical loads; you should hear barely any noise while the 80 PLUS Gold efficiency keeps waste heat low.
