Dell 3Y147 160W Server Power Supply

The Dell 3Y147 is a new ATX12V internal power supply rated at 160 watts. It accepts 110 V AC and 220 V AC input voltage. The unit measures 2.3 inches high, 2.8 inches wide and 8.5 inches deep. It is designed for Dell Dimension and OptiPlex desktop computers.

Suitable for Dell Dimension and OptiPlex owners

This supply fits Dell Dimension 2400, 2400c, 2400n, 4600 and 4600C models. It also fits Dell OptiPlex GX260, GX260n, GX270 and GX270n systems. Builders working on other brands or newer Dell chassis should look elsewhere because the connector layout and mounting holes are specific to these legacy platforms.

160 watt output rating

The single specification that decides fit is the 160 W output power. If the target system requires more than 160 watts, this unit will not deliver enough power. If the system matches the listed Dell models and needs 160 watts or less, the 3Y147 is the correct replacement.
