520W ATX Power Supply with 24-pin connector

This 520 watt ATX power supply delivers 500 watts of continuous power through a fixed 20+4 pin motherboard connector. It includes an 8-pin CPU connector, two 6-pin PCIe connectors, two SATA ports and two D-type connectors for internal drives. Active PFC corrects the power factor across a 170 to 260 volt input range. The unit carries an 80 PLUS certification rated as Other Certification.

Compact desktop and server builds needing fixed

This non-modular unit suits small-chassis desktops and entry-level servers where a single 24-pin ATX connection and basic peripheral power are sufficient. Builders who need fully modular cabling for cable management or higher GPU power delivery should look elsewhere. The fixed cable set cannot be reduced or replaced.

520 watt rated output

The 520 watt peak rating and the 80 PLUS Other Certification level are the key figures that determine whether this supply meets a system's power budget and efficiency target.

Questions about this item

How much heat and fan noise should I expect from the 520W ATX500 running continuously?

The unit uses active PFC and a non-modular design rated for 520W output, so sustained loads will generate noticeable warmth and fan spin; ensure your case has adequate airflow to keep temperatures stable.

Which connectors must my motherboard and drives already provide for this PSU to work?

Your motherboard needs a 20+4 pin ATX socket and an 8-pin CPU power header, while each SATA drive requires one of the two SATA power plugs and a graphics card needs two 6-pin PCIe connectors.

Will the 520W ATX500 reliably power an older system that still uses a 24-pin main connector and 4-pin CPU plug?

Yes, the 20+4 pin main connector splits to fit legacy 24-pin boards, and the 8-pin CPU plug separates into two 4-pin halves for older sockets, while the two 6-pin PCIe and two SATA ports cover period-correct GPUs and drives.
