  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • Lower energy use and heat via 80 PLUS Gold efficiency
  • Silent low-load operation with Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC with DC-to-DC
  • 5 V output at 30 A or 40 A up to 200 W

ATX 200 W unit for modern standby PCs

This ATX power supply delivers 200 W of continuous power and carries 80 PLUS Gold certification for high efficiency. It targets compact or low-draw systems that benefit from Modern Standby support and near-silent operation at typical desktop loads.

30 A and 40 A rails on the single 4.5 V output

The single 4.5 V rail is rated at 30 A with a 40 A peak capability, providing ample headroom for low-voltage components. It will run out of capacity when total system draw approaches the 200 W limit, so it suits builds that stay well below that threshold.

Resonant LLC with DC-to-DC and zero-RPM fan

Resonant LLC topology paired with DC-to-DC conversion supplies clean power while reducing coil whine. The zero-RPM fan mode stops the fan completely at low and medium loads, giving silent running for everyday tasks.

Questions about this item

Will the 4.5V 30A 40A 200W unit fit my existing ATX case and cable routing?

It follows the ATX form factor so it mounts in standard ATX cases and uses the usual ATX power connectors for motherboard, CPU and peripherals.

How can I confirm the 80 PLUS Gold efficiency and Zero RPM fan mode are active after installation?

Monitor system power draw with a hardware utility; the fan should stay off at low and medium loads and efficiency will meet 80 PLUS Gold thresholds under typical loads.

Does the box include every cable I need or must I buy extra modular leads?

The supplier data lists only the power supply itself; check the packaging contents for fixed or modular cables and obtain any missing leads separately if required.
