DeepCool PF400D
The DeepCool PF400D computer power supply provides stable and efficient power for computer builds. With a total output of 400W, it's a reliable foundation for office and multimedia setups without high-consumption dedicated graphics cards. The 80 PLUS certification confirms a minimum efficiency of 85% at a typical 50% load, which contributes to lower electricity consumption and less residual heat production. The internal topology uses active power factor correction and includes Taiwanese capacitors to ensure a stable power delivery.

Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the format is the power output. This indicates the maximum number of watts the power supply can continuously provide to the components in the computer. It is advisable to use an online calculator to determine the optimal power output based on your chosen components.
Efficient operation
The 80 PLUS certification confirms that the power supply efficiently converts energy from the mains into usable power for the individual components. Lower energy losses in the form of heat contribute to lower running costs and temperatures inside the case. The reduced heat production also limits the need for high system fan speeds, which has a positive effect on the overall noise level of the computer build.
Quiet cooling
Heat dissipation is handled by a 120mm fan, whose design supports quiet operation. The hydraulic bearing reduces friction and operating noise compared to standard sleeve bearings. This solution contributes to long-term reliability, which the manufacturer specifies with a mean time between failures (MTBF) of 100000 hours, even under regular load.
Easy cable management
The power supply includes fixed flat black cables that make it easier to organise the internal space of the case. Because their flat profile simplifies cable routing behind the motherboard and in tight spaces, it's possible to achieve a cleaner build aesthetic. Tidy cabling is less likely to obstruct airflow, which helps to cool all components more efficiently.
Comprehensive power supply protection
Integrated protection circuits monitor operating values and protect connected components from damage due to mains instability. This complete set of safety features protects connected components from electrical damage and supports the stable functioning of the entire system. The power supply includes over power protection, over voltage protection, short circuit protection, and under voltage protection.

80 PLUS certification in the European market
The 80 PLUS certification was created to objectively assess the efficiency of computer power supplies. This gives users a simple and clear comparison of different models. In the European market (where a 230V voltage is used), there are six levels of 80 PLUS certification with set requirements for computer 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 % |
| 80 PLUS Platinum | 92 % | 94 % | 90 % |
| 80 PLUS Titanium | 94 % | 96 % | 94 % |
