  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • Lower energy draw from 80 PLUS Gold efficiency
  • Silent running at low loads via Zero RPM fan mode
  • Clean, stable power delivery through LLC resonant topology
  • Direct replacement for Optiplex 3020, 7020, 9020 and T1700 systems

Dell OptiPlex Compatible 315W ATX PSU

This 315W ATX power supply is built as a direct replacement for Dell OptiPlex 3020, 7020, 9020 and T1700 desktop systems. It fits the standard chassis and connector layout used across those models, so IT teams and home users can swap a failed or ageing unit without rewiring or adapter cables. The unit ships new and ready for immediate installation in supported workstations.

80 PLUS Gold Efficiency with Zero RPM Fan

The supply carries 80 PLUS Gold certification, delivering high efficiency that reduces waste heat and lowers overall power draw during typical office workloads. A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation for quiet environments. Resonant LLC topology with DC-to-DC conversion further cuts coil whine and supports modern low-power sleep states.

Modern Standby Support for Faster Wake Times

Modern Standby compatibility enables extremely fast wake-from-sleep performance, a noticeable upgrade over older units that only support legacy S3 sleep. The jump is worth it when users need instant resume for productivity workflows or when replacing a noisy, less efficient supply that cannot enter the deeper sleep states required by current Windows power management. Buyers needing higher wattage for discrete graphics upgrades should look elsewhere.

Questions about this item

How do I install this 315W ATX unit in a Dell Optiplex 3020, 7020 or 9020 and what is the step most people miss?

Fit the PSU into the chassis, connect the 24-pin ATX and CPU power cables, then enable Modern Standby in the system BIOS or the fast wake and low-load efficiency features will not activate.

What maintenance will this power supply need over its life?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, so dust builds up more slowly; clean the intake vents with compressed air once a year and verify the fan spins freely under heavy load.

Which limit appears first when this 315W supply runs at sustained high load?

The 315W total output ceiling is reached before any thermal or noise limit, so the unit will trigger over-power protection if the system draws more than 315W continuously.
