PRIME Fanless PX
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.

자주 묻는 질문
PRIME Fanless PX makes the most sense when silence is a priority and the system does not need a high-wattage PSU. With 450 W and 500 W models available, it can work well for efficient desktop PCs, media systems and other builds where passive cooling is preferred. For more ideas on building a quiet PC, you can also check our guide to Seasonic power supplies for quiet builds.
The difference is simply the available power. If 450 W comfortably covers your components, there is no need to move up just because 500 W is available. For a system that sits closer to the limit or may receive a small upgrade later, the 500 W version gives a little more room. Our Wattage Calculator can help you check the complete configuration.
Both use a completely fanless design, but they cover different wattages and efficiency levels. Fanless PX comes in 450 W and 500 W with 80 PLUS Platinum certification. Fanless TX moves up to 600 W and 700 W and carries an 80 PLUS Titanium rating. If your system needs more than 500 W, PRIME Fanless TX is the natural step up.
It can be a useful option where PSU depth is limited. PRIME Fanless PX measures only 140 mm long, while still using the standard ATX/EPS form factor. Just remember that compact dimensions do not remove the need for ventilation, especially with a PSU that relies entirely on passive cooling. Our guide to choosing a PSU for your case covers PSU size and cooling considerations in more detail.
Yes, with the correct cable. PRIME Fanless PX can use a compatible Seasonic 2×8-pin to 12V-2×6 cable, but it does not support a native PSU-side 12V-2×6 cable. Always check our Seasonic Cable Compatibility page first, and make sure the PSU wattage is suitable for the graphics card and complete system.
