Power Supply for Dell Vostro Systems

This 220W ATX power supply is designed as a direct replacement for Dell Vostro 270s and 660s desktops. It carries the DPS-220UB A model designation and is supplied new. The unit delivers the rated wattage through a standard ATX form factor suitable for these specific chassis.

Efficiency Features and Noise Profile

The power supply holds 80 PLUS Gold certification, indicating high efficiency that reduces power consumption and heat output. A Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. These traits suit office or home PCs where quiet running and quick resume matter.

Builders Who Need More Power Should Look Elsewhere

The 220W rating limits this unit to systems with modest power requirements such as the listed Vostro models. Builders planning to add a discrete graphics card, multiple drives or high-wattage components will need a higher-capacity supply. Verify that your motherboard uses the standard ATX power connectors expected by this unit before ordering.

Questions about this item

What motherboard power connector does the 220W ATX supply use?

It uses a standard ATX 24-pin motherboard connector and a 4-pin CPU power connector, matching the Dell Vostro 270s and 660s chassis it replaces.

Will the DPS-220UB A fit in a Dell Vostro 270s or 660s case?

Yes, it is a direct replacement for the original DPS-220UB series units used in those models, sharing the same mounting points and cable layout.

How can I confirm the Zero RPM fan mode is active after installation?

Under light loads the fan will remain still and the 80 PLUS Gold efficiency keeps temperatures low; you will hear no fan noise until the load increases.
