1200 W ATX 3.1 Power Supply

The Thermaltake Toughpower GT Snow is a fully modular ATX 3.1 power supply rated at 1200 W. It carries 80 PLUS Gold certification and uses Japanese main capacitors. A 120 mm hydraulic-bearing fan with Smart Zero Fan mode keeps noise low. White flat cables and colour-matched connectors suit clean white builds.

Suits single-GPU builds needing native 12V-2x6 power

Builders running one PCIe 5.1 graphics card will appreciate the two native 12V-2x6 connectors rated for 600 W each. The unit meets ATX 3.1 transient-response and low-load efficiency requirements. Systems that require more than two such connectors, or that need a higher total wattage, should look at a different power supply.

Two native 12V-2x6 connectors for PCIe 5.1 graphics

The supply includes two native PCIe 5.1 12V-2x6 cables, each capable of delivering up to 600 W to a compatible graphics card. This connector count and per-cable limit are the key specification to verify against your GPU power requirements before purchase.

Questions about this item

What case clearance does the 140 mm depth require?

The unit is 140 mm deep, so the case must provide at least that much clear space behind the PSU mounting face for the body and cable bends.

Which modular ports must be used for the two native 12V-2x6 cables during installation?

Plug each supplied 12V-2x6 cable into a dedicated PCIe port on the PSU; the printed 600 W marking on the connector shows the per-cable limit.

When should the 120 mm hydraulic-bearing fan be cleaned or replaced?

Clean dust from the fan blades whenever case filters are serviced; the bearing is rated for 100,000 hours of continuous operation.
