850 W ATX 3.0 power supply

This AZZA unit delivers 850 W of continuous power and meets the ATX 3.0 specification. It carries 80 PLUS Gold certification for 90 percent efficiency at typical load. The fully modular design lets builders connect only the cables their system needs.

Sustained-load behaviour

Active PFC and a full suite of protections — UVP, OVP, OPP, OCP, SCP and OTP — keep output stable during long sessions. Hold-up time exceeds 16 ms and the power-good signal settles within 100 to 500 ms. A 120 mm fan manages thermals while the unit is rated for more than 100,000 hours MTBF.

Installation and common issues

The 160 mm depth fits most standard ATX cases, but builders should verify clearance before ordering. Four 6+2-pin PCIe cables plus a native 12VHPWR 12+4 connector support modern graphics cards. Nine SATA and four peripheral connectors cover storage and accessories. Missing the EPS cable or mixing modular leads from other units are the typical mistakes.

Questions about this item

How loud does the 120 mm fan get when the 850 W unit runs at typical load all day?

The 80 PLUS GOLD rating means 90 % efficiency at typical load, so less waste heat and lower fan speeds during extended use.

Which cables must I already have to connect the 20+4 pin main and 12VHPWR 12+4 pin GPU connectors?

All required cables — 24-pin ATX, two 4+4-pin EPS, four 6+2-pin PCIe, one 12VHPWR, nine SATA and four Molex — are included in the full-modular set.

Will the 160 mm depth and ATX 3.0 spec fit my older case and motherboard that only have 20+4 pin and 6+2 pin sockets?

Yes, the 160 mm length matches standard ATX bays, and the 20+4 pin main plus 6+2 pin PCIe cables are backward compatible with legacy boards and GPUs.
