PRIME Fanless PX-500 Unboxing
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.
