Thermaltake Toughpower SFX 1000W ATX 3.1

This SFX form-factor power supply delivers 1000 W through a full-modular design. It targets compact-system builders who need high output in a 125 mm chassis. The unit meets 80 Plus Platinum efficiency at 115 V input and supports the ATX 12V 3.1 standard. A native 12V-2x6 connector is included for modern graphics cards.

Build quality and daily connectors

A 9 cm fluid-dynamic-bearing fan provides cooling inside the black enclosure. Full-modular cabling lets you attach only the leads required, reducing clutter in tight cases. Four 6+2-pin PCIe connectors handle multiple GPUs or high-draw add-in cards. Active PFC and a 100-150 ms power-good signal contribute to stable rail delivery. Approvals cover CE, UKCA, FCC and other major safety marks.

Check before ordering

Verify that your case accepts a 125 mm deep SFX supply and that the 9 cm fan orientation matches your airflow path. Confirm the motherboard requires an ATX 12V 3.1 compliant unit with a 12V-2x6 connector. Ensure the four 6+2-pin PCIe leads satisfy every graphics card or accelerator you plan to install. Input range is 100-240 V at 50/60 Hz for worldwide use.

Questions about this item

What does the ATX 12V 3.1 standard mean for the 12V-2x6 connector on this unit?

The ATX 12V 3.1 design lets the included 12V-2x6 connector deliver up to 600 W to a compatible graphics card, while the full unit is rated for 1000 W total output.

Will the 125 mm length fit my SFX case?

The power supply measures 125 mm long, so it fits standard SFX bays; verify your chassis clearance before ordering.

How do I install the fully modular cables without missing a connection?

Plug only the cables your build needs into the unit’s modular sockets, then route each to the motherboard, GPU and drives; a common mistake is leaving the 12V-2x6 or 4+4-pin CPU connector unseated.
