SKU CH-YGN8-WZEW9

A 500 W ATX power supply with active PFC, 20+4-pin motherboard connector, two SATA connectors and a 4-pin CPU connector for desktop or server builds

  • Delivers 500 W for desktop and server builds
  • Active PFC keeps efficiency high under load
  • 20 + 4-pin main connector fits 20- and 24-pin boards
  • Two SATA connectors power drives and peripherals
  • Seven protection circuits guard against voltage and current faults

500W ATX desktop power supply

This 500W ATX power supply delivers active PFC and a 20+4-pin main connector for standard desktop and server boards. It includes two SATA power ports and a 4-pin CPU connector, supporting Intel and AMD platforms with quad-core processors and discrete graphics. The non-modular design keeps cabling fixed inside the chassis.

Sustained-load behaviour with seven protections

Active PFC and a magnetic-amplifier circuit maintain high efficiency and low ripple during continuous operation. Seven heavy protections — overvoltage, undervoltage, overcurrent, overload, short-circuit, and light-load — guard components when the system runs at full load for extended periods. A built-in 12cm fan provides quiet cooling under sustained thermal stress.

Fixed-cable installation and compatibility notes

The non-modular loom means every cable stays in the case, so routing space must accommodate all leads at once. Only two SATA connectors are provided, limiting drive counts without splitters. No PCIe 12V pins are present, so graphics cards needing external power cannot be used. The 4-pin CPU connector may not fit motherboards requiring an 8-pin EPS header.
