  • TypeATX
  • 80 PLUS Gold efficiency cuts power draw and heat

  • Resonant LLC with DC-to-DC delivers clean, stable power
  • ATX 400 W design fits standard desktop builds

400W ATX power supply for compact PCs

This 400W ATX unit delivers 80 PLUS Gold certified efficiency and Modern Standby compatibility for rapid wake times. Resonant LLC topology with DC-to-DC conversion provides clean, stable power output. The Zero RPM fan mode stops the fan completely at low and medium loads for silent running.

Capacity and headroom for mainstream builds

The 400W rating handles typical office processors and mid-range graphics cards without strain. Gold efficiency keeps heat and power draw low across the load range. At sustained heavy loads near the maximum rating the fan will spin up and headroom becomes tight for overclocked components.

Replaces older Bronze or standard units

Upgrading from a basic 80 PLUS Bronze or unrated supply brings measurable efficiency gains and quieter operation thanks to the Zero RPM mode. The jump is worthwhile when building a Modern Standby system or when coil whine and sleep-state issues need resolving. It is not suited for high-end multi-GPU configurations or extreme overclocking headroom.

Questions about this item

Will the FSP400-70PFL fit and power an older ATX chassis I already own?

Yes — it follows the ATX form factor and delivers 400 W through the standard 24-pin, CPU and PCIe connectors used by legacy boards.

How can I confirm the Zero RPM mode is active after installation?

Under light loads the fan stops completely; you can verify silent operation by listening for zero fan noise while the system idles.

Which cables come attached to the FSP400-60GHN and what must I source separately?

The unit ships with fixed ATX 24-pin, CPU 4+4-pin and PCIe 6+2-pin cables; any extra peripheral or drive cables need to be purchased separately.
