Replacement PSU for Dell Vostro Slim and SFF

This 320W TFX power supply fits Dell Vostro 200, 200S, 400 and 220S slimline and small-form-factor desktops. It replaces the original unit in systems that shipped with 200W, 250W, 300W or 350W supplies. The unit is new and built to the TFX form factor required by these chassis.

TFX form factor with 80mm double ball-bearing fan

The supply uses the compact TFX layout and cools via an 80mm fan fitted with double ball bearings for longer service life. Connectors provided are a 20+4-pin motherboard plug, a 4-pin CPU plug, two Molex, one floppy and two SATA leads. Input voltage ranges from 100V to 240V for worldwide use.

Upgrade path from 200W to 350W originals

Moving to this 320W unit adds headroom for extra drives or a modest graphics card where the original 200W, 250W, 300W or 350W supply was limiting. The supplier notes an upgrade option to 420W for builds that need more power than this model delivers.

Questions about this item

Does the 20+4 pin ATX connector on this 320W TFX unit deliver the full 320W to the motherboard?

Yes, the 20+4 pin motherboard connector carries the full 320W output to the board.

Will this TFX power supply fit the Dell Vostro 200 Slim chassis without modification?

It is built to TFX dimensions and matches the mounting holes for Vostro 200 Slim, 200S, 400 and 220S SFF cases.

How do I connect the 4-pin CPU cable when the old PSU only had a 20-pin main plug?

Plug the 20+4 pin main connector first, then attach the separate 4-pin CPU cable to the board’s CPU power socket; skipping the CPU cable is the common mistake.
