be quiet! PURE POWER 12 1000W napájací zdroj 20+4-polový ATX ATX čierny

The be quiet! PURE POWER 12 1000W is an ATX 3.1-compliant power supply unit offering 1000 W continuous output (1050 W peak) and 80 PLUS Gold efficiency. Designed for desktop systems, it supports 110–240 V AC input and comes in a compact black housing with an active cooling system that includes a 120 mm fan. The unit includes a 20+4 pin ATX motherboard connector and multiple SATA power cables in different lengths for flexible installation.

Advantages

PURE POWER 12 combines ATX 3.1 compliance and PCIe 5.1 compatibility, providing modern connector support including a dedicated PCIe 5.1 cable plus additional PCIe 6+2 cables. The 80 PLUS Gold certification ensures high conversion efficiency (approximately 90.6%), reducing wasted energy and heat. A 120 mm fan delivers active cooling while keeping noise levels low, and a range of cable lengths simplifies routing in various chassis sizes. The unit’s 1000 W capacity suits high-power components while maintaining stable delivery.

How to use

Install the power supply into a compatible ATX chassis following the chassis manufacturer’s instructions. Connect the 20+4 pin ATX cable to the motherboard, attach PCIe power cables to the GPU as required, and connect SATA power cables to storage devices. Ensure the input voltage selector (if present) matches your mains supply and route cables to maintain adequate airflow around the 120 mm fan. Power on the system and verify stable operation under load.

Recommendations

For reliable performance, allow sufficient clearance for airflow around the PSU fan, use the provided PCIe 5.1 cable for GPUs requiring the new standard, and choose cable lengths that avoid sharp bends. Maintain regular dust cleaning to preserve fan efficiency and thermal performance.
