Description

80 PLUS Platinum energy efficiency certificate, received by this power supply unit, guarantees at least 92% efficiency at 50% load. In other words, for every 100 W of energy that the power supply unit receives from the power grid, at least 92 W reaches your computer components, while the remaining 8 W is lost as heat.

The color of this power supply is Melna. The cable color is Melna and they are flat.

This is a power supply that complies with ATX 2.0 requirements. The power supply has only 6-pin and 8-pin connectors, which can handle only 75 W and 150 W of power, respectively. Modern graphics cards' high power needs exceed the capabilities of ATX 2.0 connectors. When building a system with a very powerful GPU, such as an RTX 4070, you will need an ATX 3.* standard power supply.

This power supply unit has fully-modular cables (Fully-modular) – you can connect and disconnect all the included cables as needed, reducing clutter and improving ventilation. This will be useful for those with a partially transparent computer case and for whom the aesthetic factor is particularly important.

Description - The PRIME Fanless PX series utilizes the fanless technology, which eliminates the fan noise completely, ensuring truly quiet operation. The unit not only is rated to be 80PLUS Platinum efficient, but it also has the highest power output on the fanless power supply market at the moment. The power supply is ideal any situations that demand silence from the equipment. The high quality components inside and the innovative circuit design result in clean and stable power output. The fully modular cables allow for better cable management in the computer case. 80 PLUS® Platinum
The PRIME Platinum Series achieves 80 PLUS® Platinum certification with its 92 % efficiency at 50 % system load. Micro Tolerance Load Regulation
Seasonic’s latest design keeps the output voltage within a very tight range, achieving under 0.5 % load regulation. This impressive electrical performance and stability makes this power supply an ideal choice for high-performance systems. Seasonic Fanless Design
Cooling fans inside the power supply are replaced by passive cooling based on heat dissipation. Silent operation does not only provide a more pleasant working environment but it also results in less power consumption and lower utility bills.ATX 12 VFull Modular80 PLUS Platinum CertifiedDimensions: 140 mm (L) x 150 mm (W) x 86 mm (H)Micro Tolerance Load Regulation (0.5 %)True Fanless DesignMulti-GPU setupGold plated connectors
