KHACHIMO

KHACHIMO 3020 7020 9020 T7100 255W Power Supply

SKU CH-2WQ7-209WY

ATX 255W unit with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for fast wake times

  • Product typeATX
  • Modern Standby support enables extremely fast wake-from-sleep
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption
  • Zero RPM fan mode stops the fan at low loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine
  • 255 W output powers compatible 3020 7020 9020 T7100 systems

Compatible System Models

The KHACHIMO 255W power supply is designed for systems identified as 3020 7020 9020 T7100. It fits builds that require an ATX form factor unit and benefit from Modern Standby support for rapid wake-from-sleep response.

Capacity and Headroom

Rated at 255W, the unit delivers enough power for typical office and home configurations running at low to medium loads. Under sustained heavy demand the available headroom diminishes, so workloads that regularly push toward the rated limit will reduce efficiency and acoustic advantages.

Upgrade Context

This supply replaces earlier units lacking 80 PLUS Gold certification and Zero RPM fan operation. The jump is worthwhile when cleaner power delivery, lower idle consumption and near-silent running at modest loads are priorities over maximum wattage headroom.

Questions about this item

Will the 255 W unit power a Dell OptiPlex 3020, 7020 or 9020 without an adapter?

The PSU is listed as compatible with the 3020, 7020, 9020 and T7100 chassis and uses standard ATX connectors, so it fits those systems directly.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

At typical loads the unit should run cool and quiet; the Zero RPM fan mode keeps the fan stopped at low and medium loads, which is a direct sign of high-efficiency operation.

Does the box include every cable needed for a 3020, 7020 or 9020 build?

The PSU ships with the fixed ATX cables required for those models; no extra cables are required for a standard installation.
