550 W ATX power supply for modern desktops

This 550 W ATX unit delivers 80 PLUS Gold efficiency and Modern Standby support for fast wake times and low-load savings. It suits mainstream PC builds that need reliable power without excess capacity.

Verify ATX fit and cable reach before ordering

Confirm your chassis accepts a standard ATX power supply and that the fixed cables reach your motherboard, CPU and graphics connectors. The unit uses a resonant LLC topology with DC-to-DC conversion for stable voltage regulation.

Gold-rated efficiency with semi-passive cooling

Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. The resonant LLC design reduces coil whine and supports deeper sleep states for everyday quiet performance.

Questions about this item

Does the box include cables or do I need to buy a PCIe 8-pin cable separately?

The PSU ships with fixed and modular cables covering the 24-pin ATX, 4+4-pin CPU and PCIe connectors; no extra cables are required for a standard build.

The title lists Z1, G6, 800, 880, G4 and G5 — which one do I order for a 550 W ATX unit?

All references point to the same 550 W ATX power supply; choose the listing that matches your region or SKU preference.

What does the 80 PLUS Gold rating mean for daily power draw on this 550 W unit?

It certifies high efficiency across typical loads, so the PSU wastes less electricity, runs cooler and keeps fan noise lower.
