220 W ATX power supply

The KHACHIMO DPS-220TB is a new 220 W ATX power supply designed for low-power systems such as video recorders or monitoring appliances. Its 80 PLUS Gold certification ensures high efficiency, reducing consumption, noise and heat during everyday operation. Modern Standby compatibility allows extremely fast wake-from-sleep transitions and improved low-load performance.

Suits compact monitoring builds

Builders assembling small-footprint recorders or surveillance boxes that demand quiet, efficient power will benefit from the Zero RPM fan mode and resonant LLC topology with DC-to-DC conversion. Systems requiring higher wattage for multiple GPUs or heavy compute workloads should look at larger-capacity units instead.

80 PLUS Gold efficiency rating

The single specification that decides fit is the 80 PLUS Gold certification, which guarantees high-efficiency operation across typical loads, directly lowering power draw and enabling cooler, quieter running. Verify that 220 W meets the total power budget of every component in the chassis before purchasing.

Questions about this item

How do I install this ATX power supply and what step do builders often miss?

Secure the unit in the case with four screws, attach the 24-pin motherboard and CPU power cables, then ensure the rear master switch is turned on — many builders leave it off after wiring.

What maintenance or replacement will this 220W supply need over time?

The fan may eventually require cleaning or replacement; 80 PLUS Gold efficiency and LLC resonant topology reduce component stress, extending the interval before any service is necessary.

Which limit appears first when this supply runs under sustained load?

The 220W maximum output is the primary ceiling; Zero RPM mode disengages as temperature rises, and the Gold-rated design keeps thermals in check until that power limit is reached.
