EPS12V

EPS12V refers to a power supply connector standard developed by Intel for server and high-end desktop computer systems. The "EPS" stands for Entry-Level Power Supply, and "12V" indicates the primary voltage supplied by the connector. This standard was introduced to provide more robust power delivery capabilities compared to older ATX standards, particularly for power-hungry components like multi-core CPUs and high-end graphics cards.

The EPS12V connector typically features 8 pins, though it can sometimes be found as a 4+4 pin configuration that can be split to accommodate older 4-pin CPU power sockets. Its primary purpose is to deliver a dedicated 12V power rail to the motherboard's CPU voltage regulator module (VRM). This separate and robust 12V supply is crucial for maintaining stable operation under heavy computational loads. While ATX power supplies also provide 12V power, the EPS12V standard is designed for higher current delivery and greater stability, making it a common feature in professional workstations and servers where reliability is paramount.
