ATX 3.1 power supply for modern builds

This Thermaltake Toughpower GT unit delivers 850 W through a fully modular design that meets the ATX 3.1 specification. It is intended for system builders who need a native 12VHPWR connection for current graphics cards and a clean cable layout.

Snow finish with hydraulic bearing fan and full

The 140 mm deep chassis uses a 12 cm hydraulic bearing fan that stops at low load under Smart Zero Fan control. Full modular cabling lets you attach only the 24 pin ATX, two 4+4 pin CPU, four 6+2 pin PCIe, one 12VHPWR, SATA and peripheral leads required for the build.

Check case depth and cable routing before ordering

Verify that your chassis can accommodate a 140 mm long power supply and that the 550 mm main cable reaches the motherboard connector. Confirm the 600 mm 12VHPWR lead suits your graphics card position and that the 700 mm CPU cables reach the socket without strain.

Questions about this item

What does the ATX 3.1 standard mean for the 12VHPWR connector on this unit?

The native 12VHPWR (12+4) PCIe connector is rated for 450 W and complies with the ATX 3.1 power excursion requirements for modern graphics cards.

Will the 140 mm depth fit in a standard mid-tower case?

At 140 mm long and 150 x 86 mm wide, it matches the typical ATX form factor used in most mid-tower chassis.

How do I connect the 12VHPWR cable without melting the plug?

Push the 12+4 pin connector straight in until the latch clicks; the 600 mm cable reaches most GPU positions without sharp bends.
