New 240W Power Supply for Dell Optiplex SFF - Reliable Fit

In this review of the New 240W Power Supply for Dell Optiplex SFF series, the bottom line is simple: this replacement unit is for owners of Small Form Factor Dell Optiplex desktops who need a direct-fit power supply that restores a machine to working order without fuss. The reviewer found it most compelling for technicians and DIYers because it matches multiple Dell part numbers and model variants, delivers the rated 240W output, and uses the same SFF 8-pin and 4-pin connectors found in the original hardware.

Key Features

• Wide compatibility: Matches many Dell Optiplex SFF model numbers so it fits Optiplex 3040, 3046, 3250, 3650, 3656, 5040 and 7040 without modification.
• Multiple part numbers supported: Accepts a long list of compatible part numbers so it can replace units labeled THRJK, 4GTN5, 4R1KT and other OEM codes.
• Correct connectors: Provides the required P1 8-pin and P2 4-pin SFF power connectors to plug directly into the system board.
• Dual AC input range: Operates on 100-127V at 7A or 200-240V at 3.5A making it usable in varied mains environments.
• Full 240W output: Supplies up to 240W max which is suitable for standard SFF configurations that do not need a high-wattage graphics upgrade.

Who It's For

This power supply is aimed at IT technicians, refurbishers, and small-business owners who maintain fleets of Dell Optiplex SFF desktops and need a like-for-like replacement. The clear advantage is that it restores compatible systems quickly because it follows the original connector layout and part numbering.

It is not intended for users who plan to add high-power discrete GPUs or heavily overclock their systems; SFF chassis and a 240W supply impose limits. Buyers who require a non-standard cable set or higher wattage should look for an alternate full-size or higher-capacity supply.

Pros & Cons

Pros
