Power supply for PCIe 5.1 builds

The be quiet! Pure Power 13 M 1000W is an ATX 3.1 compliant unit rated at 1000 W with 80 PLUS Gold efficiency up to 94.4 percent. It uses a single 12 V rail, LLC technology and a semi-passive 120 mm fan for quiet operation. Fully modular cables keep the interior tidy.

Suits high-end GPU systems; not for multi-GPU rigs

This unit fits builds that need one PCIe 5.1 12V-2x6 connector rated for 600 W plus four 6+2 pin connectors for overclocked graphics cards. It also provides six SATA and two PATA plugs for drives. Builders planning multiple flagship GPUs or workstations requiring more PCIe power leads should look elsewhere.

Deciding spec: one PCIe 5.1 12V-2x6 600W connector

The presence of a single native 12V-2x6 connector delivering up to 600 W determines compatibility with the latest graphics cards. If the target GPU demands that connector, this supply meets the requirement; if the build needs two such connectors, it does not.

Questions about this item

What does the 1000W maximum power mean for a real build?

The 1000W rating means the unit can deliver up to 1000 watts continuously to all components combined, supporting high-end CPUs and a power-hungry GPU without hitting its limit.

What does ATX 3.1 and PCIe 5.1 support cap in practice?

ATX 3.1 compliance and PCIe 5.1 support let the PSU handle the new 12V-2x6 connector rated for 600W, so a single modern graphics card can draw its full power through one cable.

What does the 120mm fan and semi-passive design need to fit in my case?

The 120mm fan sits in a standard ATX power-supply housing, so any case with a regular ATX PSU bay and enough clearance for the modular cable plugs will accommodate it.
