Be quiet! PURE POWER 12 M 1200W
The Be quiet! Pure Power 12 M computer power supply delivers 1200W of power for modern PC builds with high demands for stability and efficiency. Its design fully complies with the ATX 3.0 specification, ensuring compatibility with the latest graphics cards and motherboards. Fully modular cable management contributes to a clean installation and unrestricted airflow inside the computer case. The 80 PLUS Gold certified efficiency limits waste heat generation and reduces running costs. The PSU splits power across two strong and independent 12V rails. This solution enhances voltage stability for key components, such as the multi-core processor and high-performance graphics card, which draw power independently of each other, reducing mutual interference. The separate power paths deliver consistent performance even during demanding computational tasks or gaming.

Choosing a power supply
When choosing a suitable PC power supply, the key parameter, besides the format, is its power output. This indicates the maximum number of Watts the PSU can continuously supply to the components in the computer. It's a good idea to use an online calculator to work out the optimal power output based on your chosen components.
ATX 3.0 standard of the Be quiet! Pure Power 12 M 1200W
This PSU fully supports the ATX 3.0 standard, which defines stricter power supply requirements and the ability to handle short-term power spikes. It can manage massive power fluctuations of up to twice its rated value and delivers a stable voltage even during extreme load jumps. It includes a 12VHPWR connector to power PCIe 5.1 standard graphics cards, meeting the demands of high-performance graphics accelerators.
High 80 PLUS Gold efficiency
The 80 PLUS Gold certification confirms high electrical energy conversion efficiency, with a rating of up to 91.5%. This results in lower consumption, and in standby mode, the draw drops to less than 0.12W. Higher efficiency means smaller energy losses converted into heat. The PSU components heat up less, which extends their lifespan and reduces cooling requirements.
Modular cabling of the Be quiet! Pure Power 12 M 1200W computer power supply
The fully modular cable system simplifies the PC building process. Long, sleeved cables up to 100cm long make installation easy, even in large cases. You only connect the cables that are essential, for example, from the six SATA or four PCIe connectors. This approach eliminates excess cabling in the case, improves air circulation and makes future upgrades or component swaps easier.
Quiet operation with speed control
Cooling is handled by a 120mm Be quiet! fan with an optimised blade shape and a durable rifle bearing. Its speed is controlled based on the current temperature and load of the power supply, and the fan maintains a low noise level even at high performance. The maximum noise level does not exceed 34.3dB(A), which contributes to the quiet operation of the entire computer build. The equipment includes a 16-pin 12VHPWR connector, which supplies up to 600W to a single component. In addition, the PSU also offers four classic PCIe 6+2-pin connectors, and this connector is used specifically to power high-performance graphics cards. It eliminates the need for adapters for PCIe 5.1 standard cards.
Comprehensive protection suite of the Be quiet! Pure Power 12 M 1200W computer power supply
The PSU's electronics integrate a complete set of safety features. These include over-voltage (OVP), under-voltage (UVP), over-current (OCP), over-power (OPP), and short-circuit (SCP) protection, with the system also featuring thermal protection and surge and inrush protection (SIP). These elements protect connected components from damage due to power grid instability.

80 Plus certification in the European market
The 80 Plus certification was created to objectively assess the efficiency of PC power supplies. This provides users with a simple and clear way to compare different models. In the European market (where 230V is used), there are six levels of 80 Plus certification with set requirements for PC power supplies. Higher energy efficiency primarily means lower energy consumption.
| PC power supply load | Efficiency at 20% load | Efficiency at 50% load | Efficiency at 100% load |
|---|---|---|---|
| 80 PLUS | 82% | 85% | 82% |
| 80 PLUS Bronze | 85% | 88% | 85% |
| 80 PLUS Silver | 87% | 90% | 87% |
| 80 PLUS Gold | 90% | 92% | 89% |
