200 W ATX Power Supply

This 200 W ATX power supply delivers 45 A on the 4.2 V rail for compact or low-power systems. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for stable output. Modern Standby support enables fast wake times and improved low-load efficiency.

Home and office builds needing quiet.

The Zero RPM fan mode stops the fan at low and medium loads for near-silent operation, suiting media PCs or workstations in quiet rooms. Builders who need more than 200 W for discrete graphics cards or high-core-count CPUs should consider higher-capacity units instead.

45 A on the 4.2 V rail

The single-rail design provides 45 A at 4.2 V, defining the total power budget for the platform. Verify that the combined draw of the motherboard, memory, storage and any add-in boards stays within this limit before purchasing.

Questions about this item

Does the box include all cables or do I need to buy any separately?

The power supply ships with the standard ATX connector set; no extra cables are required for a typical build.

Should I pick the 200 W unit or a higher-wattage model?

Choose this 200 W model if your system draws up to 200 W; move to a larger unit only when your components exceed that limit.

What does the 80 PLUS Gold rating actually do for my PC?

It means the unit runs at up to 80 % efficiency at typical loads, cutting waste heat and keeping the fan off longer in Zero RPM mode.
