Quick specs

Semi-passive cooling for silent operation

The Pure Power 13 M features intelligent semi-passive cooling that keeps the fan off during low to medium loads, ensuring near-silent operation during everyday tasks. When cooling is required, the 12 cm fan operates at speeds between 0-2000 RPM, maintaining optimal temperatures without excessive noise. This makes it perfect for noise-sensitive environments where acoustic performance matters as much as raw power.

Next-gen graphics card ready

With both a PCIe 5.1 cable and multiple PCIe 6+2 cables included, this PSU offers outstanding compatibility with current and next-generation graphics cards. The 1000W total power and 1050W peak capacity provide ample headroom for high-end GPUs, while the fully-modular cabling design allows clean, organised builds without unnecessary cable clutter. The ATX 3.1 compliance ensures stable power delivery even under heavy transient loads from modern graphics cards.

Premium build quality and protection

Built with reliability in mind, the Pure Power 13 M includes comprehensive protection features: over current, over power, over voltage, overheating, short circuit, surge & inrush protection, and under voltage protection. The 100,000-hour MTBF rating demonstrates exceptional durability, while the 0.98 power factor and active PFC ensure efficient power usage. The 150 x 160 x 86 mm form factor fits standard ATX cases, and the 2.64 kg weight reflects quality components throughout.
