Power and standard compliance

The Thermaltake Toughpower GT delivers 850 W through an ATX 3.1 design that includes native PCIe 5.1 support. A single 12V rail supplies stable current for high-end gaming and workstation builds. 80 PLUS Gold certification confirms efficiency above 85% at typical loads.

Cable layout and case fit

The unit is fully modular with low-profile flat black cables and provides 16 SATA power connectors for storage arrays. Maximum PSU length is 140 mm, so verify that your chassis accommodates this depth before ordering. The main board connector uses a 20+4 pin arrangement.

Thermal behaviour under load

Smart Zero Fan technology keeps the 12 cm hydraulic bearing fan stationary during light workloads, then ramps speed as power draw rises. Hold-up time exceeds 17 ms at 80% load, while protection circuits cover OVP, UVP, OCP, OPP, OTP and SCP for sustained operation.

Questions about this item

Does the Toughpower GT 850W come with all cables attached or do I need to buy any separately?

The unit is fully modular so only the cables you need are connected; the package includes the low-profile flat black cable set and the native 12V-2x6 (12+4 pin) GPU connector, nothing extra is required.

Should I choose this 850W model or a higher wattage for a GPU that draws up to 450W?

An 850W Gold-rated supply with a single high-amperage +12V rail covers a 450W graphics card plus CPU and peripherals with headroom for transient spikes.

What does the 80 PLUS Gold rating actually deliver once the PSU is inside my PC?

It guarantees at least 85% efficiency at typical loads and up to 90% at 115V input, meaning less waste heat and lower electricity draw during gaming or workstation tasks.
