Thermaltake PS-TPD-0850NNFAGU-3 850 W power supply

Thermaltake Toughpower GX3 850 W ATX 3.0 PSU

This Thermaltake Toughpower GX3 unit delivers 850 W of continuous power in an ATX 3.0 compatible design. It includes a native 12VHPWR connector and four 6+2-pin PCIe cables for modern graphics cards. A 120 mm fluid-dynamic-bearing fan and 105°C electrolytic capacitors keep operation quiet and reliable. The unit carries 80 PLUS Gold certification and a full suite of protection circuits.

Ideal for mid-range to high-end gaming builds

Builders assembling systems with current-generation GPUs that draw power through the 12VHPWR interface will find the native connector and 850 W headroom a direct fit. Systems that require higher wattage, modular cabling, or a smaller form factor such as SFX should consider other models. The fixed cable layout also means cable management space must be available in the case.

The deciding spec is the ATX 3.0 compliant 12VHPWR

This single specification determines whether the PSU can power a modern graphics card without an adapter. If the target GPU uses the 12VHPWR socket, this unit connects natively and meets the ATX 3.0 transient-response requirements. If the GPU relies solely on traditional 6+2-pin plugs, the 12VHPWR cable simply remains unused.
