Dell 220 W ATX12V power supply

This internal power supply delivers 220 W through the ATX12V standard and is built specifically for the Dell Optiplex 210L and Optiplex GX520 desktop computers. It meets RoHS environmental requirements and carries the Dell part number NC912.

Practical limits of the ATX12V standard at 220 W

The 220 W ceiling restricts the unit to systems with modest processor and peripheral loads; high-end graphics cards or multiple drives will exceed the available headroom. Only the connectors native to the Optiplex 210L and GX520 are provided, so adapters cannot add missing rails.

Installation notes for Optiplex 210L and GX520

The supply fits directly into the Optiplex 210L and GX520 chassis using the original mounting points and connector layout. Builders who need more power or a different connector set will find this unit unsuitable. A common mistake is assuming the unit fits other Dell towers without verifying the exact model match.

Questions about this item

Which Dell Optiplex desktop is the 220 W unit designed for?

The supply is built for the Optiplex 210L and also fits the Optiplex GX520, so choose it when you are replacing the original brick in either of those chassis.

What does the 220 W rating mean once the supply is installed?

It is the maximum continuous output the unit can deliver to the motherboard, drives and add-in cards; typical office workloads on these desktops draw well below that ceiling.

What power standard does the ATX12V label refer to and what does it limit?

ATX12V defines the 12 V rail layout and connector set used by these Optiplex boards; the 220 W cap is the total power budget across all rails combined.
