KHACHIMO

KHACHIMO 3020 7020 9020 8Pin 290W Power Supply

SKU CH-BG99-0TQHQ

ATX power supply for 3020 7020 9020 systems with 8-pin connector and 290W output

  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • Lower power draw and heat thanks to 80 PLUS Gold efficiency
  • Near-silent operation at low load via Zero RPM fan mode
  • Clean, stable power delivery through Resonant LLC with DC-to-DC conversion
  • Compatible with KHACHIMO 3020, 7020, 9020 systems

Compatible Desktop Models

The KHACHIMO 290 W ATX power supply fits the 3020, 7020 and 9020 chassis and delivers 8-pin CPU power. It is built for system integrators and owners of those specific desktops who need a direct replacement unit.

Sustained Load Behaviour

An 80 PLUS Gold rating means efficiency stays high across the load curve, so heat and fan noise remain low during extended workloads. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and suppresses coil whine when the system runs for hours.

Upgrade Context

This unit replaces the original HU290AM-01, D290EM-01, AC290EM-00, F290EM-00, HU290EM-00 or L290BM-01 supply when the old one fails or becomes noisy. The jump is worth it if the desktop must support Modern Standby sleep states or the owner wants zero-RPM fan silence at idle.

Perguntas sobre este artigo

How much noise and heat does the 290W unit produce when running continuously?

The 80 PLUS Gold certification means high efficiency, so the 290W supply draws less power from the wall and generates less heat. Zero RPM Fan Mode stops the fan at low and medium loads, giving near-silent operation during typical all-day use.

Which connectors must my Dell OptiPlex 3020, 7020 or 9020 already have for this supply to work?

This unit is built as a direct replacement for the HU290AM-01, D290EM-01, AC290EM-00, F290EM-00, HU290EM-00 and L290BM-01 models. It uses the same ATX form factor and the 8-pin connector found on those chassis.

Will the Modern Standby feature work with the older motherboard in my 3020, 7020 or 9020?

Modern Standby compatibility enables extremely fast wake-from-sleep and better low-load efficiency on supported platforms. The resonant LLC topology with DC-to-DC conversion also allows more energy-efficient sleep states on compatible hardware.
