Product information

Description

The Thermaltake Toughpower SFX 850W Gold (model SFX-850AH8FKG) is a fully modular 850 W SFX power supply unit designed for small form-factor and ATX builds. It is 80 PLUS Gold certified, complies with Intel ATX 3.0 specifications and includes a native 16‑pin (12VHPWR) PCIe Gen 5.0 connector for next‑generation GPUs. The compact SFX form factor fits ITX and ATX cases and the unit ships with an SFX-to-ATX adapter bracket for flexible installation options.

Advantages

The PSU offers native PCIe Gen 5.0 support via a 16‑pin 12VHPWR connector capable of delivering up to 450 W to compatible graphics cards, full compatibility with Intel ATX 3.0 power‑timing and excursion requirements, and high energy efficiency with 80 PLUS Gold certification. It features low ripple noise (<30 mV across +12V, +5V and +3.3V), strict voltage regulation (±2% on major rails), a minimum 17 ms hold‑up time at full load, and a high‑quality design with 100% Japanese 105°C electrolytic capacitors. The unit includes fully modular low‑profile flat cables, a 92 mm fluid dynamic bearing fan with Smart Zero Fan operation, and an SFX-to-ATX bracket for case compatibility.

Suitable for

  • Compact gaming PCs with PCIe Gen 5.0 graphics cards
  • Mini-ITX systems where space is limited
  • Small form-factor workstations requiring stable, high-current +12V supply
  • Upgrades to systems needing Intel ATX 3.0 compliance

Key specifications

  • Total power: 850 W
  • 80 PLUS certification: 80 PLUS Gold
  • Motherboard connector: 24‑pin ATX
  • PCIe connector: Native 16‑pin (12VHPWR) supporting up to 450 W for GPU
  • Form factor: SFX (includes SFX-to-ATX adapter bracket)
  • Fan: 92 mm fluid dynamic bearing with Smart Zero Fan
  • Ripple noise: <30 mV on +12V, +5V, +3.3V
  • Voltage regulation: <±2% on major rails
  • Hold‑up time: ≥17 ms at 100% load
  • Capacitors: 100% Japanese 105°C electrolytic capacitors
  • Product colour: Black
  • Weight: 1 kg

How to use

Install the SFX power supply into your ITX or suitable ATX case using the included mounting hardware; if your case requires, attach the supplied SFX-to-ATX adapter bracket before mounting. Connect the 24‑pin ATX main power cable to the motherboard, attach CPU power and peripheral cables as required, and plug the native 16‑pin (12VHPWR) connector directly to a compatible PCIe Gen 5.0 GPU when needed. Use the modular cable selection to route low‑profile flat cables for improved airflow and tidy cable management. Observe standard safety precautions: power off and unplug the system before installation and ensure all connectors are fully seated.

Usage recommendations

For stable operation with high‑power graphics cards, follow the GPU manufacturer’s recommended wattage printed near the 12VHPWR connector and ensure your total system load stays within the 850 W rated capacity. Enable Smart Zero Fan behavior by allowing the PSU to operate under light loads to keep noise minimal; if sustained heavy loads are expected, verify case ventilation to maintain optimal cooling.
