  • Faster wake from sleep with Modern Standby support
  • Lower power draw and cooler running thanks to 80 PLUS Gold efficiency
  • Near-silent operation at typical loads with Zero RPM fan mode
  • Clean, stable power delivery from resonant LLC topology with DC-to-DC conversion
  • Compatible with Optiplex 3020, 7020, 9020 and T1700 systems

Dell Optiplex Compatibility

This 315W ATX power supply is built for Dell Optiplex 3020, 7020 and 9020 desktops as well as the Precision T1700 workstation. It targets IT departments and home users who need a direct replacement that fits the original mounting points and connectors without adapters. The unit is new and carries the 4FCWX and H315ES-00 part identifiers for easy cross-reference.

Sustained Load Behaviour

The resonant LLC topology with DC-to-DC conversion delivers stable voltages during continuous workloads rather than only in short bursts. Clean power output reduces coil whine and supports modern sleep states so the system remains efficient when left running for long periods. 80 PLUS Gold certification confirms high efficiency across the load range, lowering waste heat during extended use.

Thermals Noise and Power Draw

Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation in typical office tasks. When the fan does spin, the efficient design keeps temperatures lower than less certified units. Modern Standby compatibility enables extremely fast wake-from-sleep times while maintaining low power draw at idle.

Questions sur cet article

How loud and hot does the 315W unit run when it powers a Dell OptiPlex 9020 all day?

The 80 PLUS Gold rating and Zero RPM fan mode keep noise and heat low; the fan stops completely at low and medium loads.

Which cables or adapters must I already have to install this 4FCWX supply in a T1700 chassis?

It uses a standard ATX connector layout, so the motherboard and drive cables already fitted in the OptiPlex 3020, 7020 or 9020 are sufficient.

Will this H315ES-00 supply work reliably with the older components kept from a 3020 build?

Yes, the resonant LLC topology with DC-to-DC conversion delivers clean, stable power that supports legacy sleep states and protects older parts.
