1200W ATX12V 3.1 power supply
The be quiet! BP030US delivers 1200 W through a single 12 V rail, meeting ATX12V 3.1 and PCIe 5.1 specifications. It targets high-end gaming and workstation builds that demand stable, high-wattage power. Two 90° angled 12V-2x6 connectors simplify cable routing for modern graphics cards.
Semi-passive zero-RPM cooling
A 140 mm Pure Wings 3 fan stops completely at low load for silent operation. When active, it continues running for two to five minutes after load drops to prevent frequent start-stop cycles. Dual 80 PLUS Platinum and Cybenetics Platinum ratings certify up to 94.3 % efficiency across typical loads.
Sustained load stability through LLC regulation
LLC resonant topology provides tight voltage regulation during prolonged heavy workloads. The single massive 12 V rail maintains consistent output without multi-rail balancing overhead. Active PFC and a 100-500 ms power-good signal ensure clean, reliable power delivery throughout extended sessions.

Questions about this item
How do I install the 12V-2x6 connectors and what step is often missed?
Route each 90° angled 12V-2x6 cable to the GPU, seat both plugs fully until the latch clicks, then verify the PSU side is locked into the correct PCIe 5.1 port; the angled heads can feel seated before the latch actually engages.
What maintenance will the Pure Wings 3 140mm fan need later?
The 140 mm fan uses a rifle bearing; clean dust from its blades and the mesh intake every 6-12 months with low-pressure air, and expect the semi-passive zero-RPM mode to keep the fan off at low load, reducing wear.
What limit appears first during sustained full-load operation?
The single 12 V rail delivers the full 1200 W, so the first constraint is thermal — the 140 mm fan must spin up from zero-RPM and maintain airflow through the 160 x 150 x 86 mm chassis to keep efficiency near 94.3%.
