Compact SFX power supply for small-form-factor

This Thermaltake Toughpower SFX unit delivers 750 W from a 125 mm deep chassis that fits SFX bays. An included SFX-to-ATX adapter bracket lets the same PSU work in standard ATX cases as well. It targets builders who need high output in a minimal footprint.

90 mm fluid-dynamic-bearing fan runs under 80

At 115 V input the supply meets Platinum efficiency, reducing waste heat and fan speed in typical loads. Active PFC and a 100–150 ms power-good signal keep voltage stable. The fan diameter and bearing type are chosen for quiet operation at normal desktop power levels.

Full modular cabling with native 12V-2x6 connector

Only the cables you need stay in the case, freeing space for airflow and cable routing. Two 6+2-pin PCIe connectors serve conventional graphics cards while the 12V-2x6 interface supports newer 12+4-pin GPUs. The 125 mm length leaves room in tight layouts.

Questions about this item

How do I install the SFX unit in a standard ATX case, and which bracket step is often missed?

Mount the 125 mm long SFX body using the included SFX-to-ATX adapter bracket; the step often missed is securing all four bracket screws before sliding the PSU into the case.

What maintenance or replacement will the 9 cm FDB fan need later?

The fluid-dynamic-bearing fan is rated for over 100,000 hours MTBF; under normal use it rarely needs replacement, but if noise rises a direct 9 cm FDB swap is the only service item.

At what point does the 80 PLUS Platinum efficiency limit appear under sustained load?

Efficiency is certified at 115 V input; the first limit under sustained use is thermal — the 90 mm fan must move enough air to keep internal temperatures within the Platinum spec.
