In Win 300 W TFX server power supply

This proprietary TFX12V v2.31 unit delivers 300 W and supports Intel Haswell processors. It accepts 115/230 V AC input and provides +3.3 V at 16 A, +5 V at 16 A, dual +12 V rails at 18 A each, -12 V at .3 A and +5 Vsb at 2.5 A. An 80 mm fan with smart thermal control balances noise and cooling while the unit meets MTBF of 100 K hours at 25 °C.

Who this suits and who should look elsewhere

Ideal for technicians servicing In Win BL or BP series servers that require a TFX form-factor replacement. The fixed cable set includes a 20+4 pin main connector, a 4+4 pin CPU connector, three SATA connectors, one peripheral connector and one FDD connector. Builders needing higher wattage, modular cabling, or a standard ATX form factor should look elsewhere.

Deciding specification: TFX12V v2.31 proprietary

This supply fits only chassis designed for the TFX12V v2.31 standard with the exact 85.0 x 175.0 x 65.0 mm dimensions. Verify that your server cabinet matches these measurements and the proprietary pin-out before ordering. Operating temperature range is +10 °C to +40 °C.

Questions about this item

What are the exact dimensions of the TFX unit so I can confirm it fits my server chassis?

The power supply measures 85.0 mm wide, 175.0 mm long and 65.0 mm high, matching the standard TFX12V v2.31 form factor.

Does the 4+4-pin 12 V CPU connector split for boards that only take a 4-pin plug?

Yes, the 4+4-pin connector separates into two 4-pin halves; install only the half that matches your motherboard socket and leave the other half unconnected.

Is the 80 mm cooling fan user-replaceable if it becomes noisy after the rated MTBF?

The 80 mm fan is mounted inside the sealed supply; replacing it requires opening the unit, which voids safety certifications, so the entire supply is normally swapped once the 100 K-hour MTBF is reached.
