The power supply is like the heart of a PC, providing power to various hardware components. The constantly advancing technology nowadays has led to a continuous decrease in the total power consumption of PC central processing units (CPUs). However, with the extremely fast increase in GPU power consumption, the overall power consumption of PCs has brought new challenges to the power supply. At the same time, OEM PC power supplies also have an essential demand for smaller size and better cost-effectiveness in the DIY market.
