TFX 400 W replacement for AcBel PC8046

This TFX power supply delivers 400 W continuous output to replace the original AcBel PC8046 unit in slimline and small-form-factor desktops. It upgrades systems that shipped with 200, 250, 300 or 350 W units and fits the same mounting pattern. The AT-type design targets owners of compatible Dell and other SFF chassis needing a direct swap.

Verify connector fit and chassis clearance

Confirm the motherboard accepts a 20+4 pin main connector and a 4-pin CPU plug before ordering. The unit also provides two Molex, one floppy and two SATA power leads for drives and peripherals. Ensure the TFX form factor matches your case internal layout and that the 80 mm fan orientation aligns with the chassis airflow path.

Steady 400 W under sustained load

The supply is rated for 400 W continuous power rather than a short-term peak, supporting extended workloads without throttling. An 80 mm double ball-bearing fan provides active cooling across the operating range. Input voltage auto-ranges from 100 to 240 V, so output remains stable during prolonged sessions.

Preguntas sobre este artículo

Does the TFX 400 W unit ship with every cable I need, or must I buy extra connectors?

The box includes a 20+4 pin motherboard cable, a 4-pin CPU cable, two Molex leads, a floppy lead and two SATA leads — everything required for a standard slimline build.

My AcBel PC8046 originally had a 300 W supply; is the 400 W version the right upgrade?

Yes — this 400 W TFX unit replaces 200, 250, 300 or 350 W models and is rated for up to 420 W peak, so it covers your 300 W original with headroom.

Will the 400 W rating hold up when the PC is running a full load of drives and a discrete graphics card?

The supply delivers a steady 400 W through its 20+4 pin, 4-pin CPU, two Molex and two SATA connectors, and the 80 mm double ball-bearing fan keeps temperatures stable under continuous load.
