Chieftec Polaris power supply unit 750 W 20+4 pin ATX PS/2 Black

The Chieftec Polaris 750 W is a fully modular ATX power supply designed for desktop PCs. It delivers 750 W of total power with an 80 PLUS Gold efficiency rating and compact dimensions (140 mm length). The unit includes a 20+4 pin ATX motherboard connector, multiple SATA power leads, and an active cooling solution with a 120 mm fan, meeting RoHS compliance for safer materials.

Advantages

The Polaris 750 W combines a high-efficiency 80 PLUS Gold certification with a modern LLC half-bridge converter and DC-to-DC topology to provide stable voltages and improved power density. Fully modular cabling simplifies installation and cable management, while the 140 mm compact length and long cable runs (up to 650 mm) make the PSU suitable for both compact and larger PC builds.

Suitable for

• Gaming desktops with mid to high power requirements
• Workstations requiring stable 12 V rails and modular cabling
• Compact ATX builds where a shorter PSU is needed
• Systems needing multiple SATA devices
