With its ability to output 500 Watts continuously, it is ideally suited for gaming PCs and, thanks to its powerful 12V rail rated for 41A, also perfect for use with demanding high-performance hardware.

Thanks to the automatically controlled 120mm fan, users will benefit from the low noise produced by the unit, being virtually silent at low loads. The high efficiency of the Seasonic Core GC-500 means that it maintains 92 percent efficiency at 50% load, successfully earning it the sought after 80 PLUS Gold certification. This means that not only is the power supply efficient, it also produces less heat and uses less power - a blessing when it comes to constantly rising energy prices.

For drives and the like, the PSU includes four SATA and three 4-Pin Molex connectors. The cables are optimised for airflow and for minimising their footprint within the case.
