  • Zero RPM fan mode stops the fan at low and medium loads for near-silent running

Dell OptiPlex Compatible PSU

This 315 W ATX power supply is built for Dell OptiPlex 3020, 9020, XE2 and T1700 desktops. It delivers the exact connector layout and form factor those systems expect, making it a direct replacement for the original D315ES-00, H315ES-00, 4FCWX, VX372, L255ES-00 or L255AS-00 unit. The 80 PLUS Gold rating means lower running costs and less waste heat inside a compact chassis.

Best for OptiPlex owners

Ideal for IT teams refreshing fleets of OptiPlex 3020, 9020, XE2 or T1700 machines where a like-for-like 315 W unit is required. Builders assembling custom ATX rigs, systems needing auxiliary GPU power connectors, or anyone wanting modular cables should look elsewhere because this unit uses fixed cables and the native Dell pin-out.

Sustained-load behaviour

Under continuous load the resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and reduces coil whine. The Zero RPM fan mode stays off at low and medium loads, so the supply runs silently during typical office workloads, then spins up only when thermal limits demand it. Modern Standby support allows near-instant wake from sleep without sacrificing efficiency.

Questions about this item

Does this 315 W ATX unit fit the Dell OptiPlex 3020, 9020, XE2 or T1700 chassis I already own?

Yes — the supplier lists it as a direct replacement for OptiPlex 3020, 9020, XE2 and T1700 systems.

Will the 80 PLUS Gold efficiency and Zero RPM fan mode still work if I keep my older motherboard and CPU?

Yes, the Gold rating and fan-stop feature operate independently of the host platform; they engage whenever load stays in the low-to-medium range.

How can I confirm Modern Standby is active after installing the D315ES-00?

Put the PC to sleep; if it wakes almost instantly and the fan remains off at idle, Modern Standby and Zero RPM mode are functioning.
