## Summary description

The Chieftec PowerUp GPX-850FC is an 850 W ATX power supply unit designed for PCs. It features a 20+4 pin motherboard connector, 80 PLUS Gold certification for energy efficiency, and operates on an AC input voltage of 100-240 V. With a fan diameter of 12 cm and one fan for cooling, it ensures reliable performance. The included cables support various connections including AC, CPU, PCIe, and SATA, with lengths suitable for flexible installation.

## Long description

The Chieftec PowerUp GPX-850FC is an 850 W ATX power supply unit designed for desktop PCs. It uses modern full-bridge LLC and DC-to-DC topology to provide stable voltages with low ripple, and its compact 140 mm length supports installations in smaller cases while delivering 80 PLUS Gold efficiency.
Advantages
The PowerUp GPX-850FC combines high power density and efficient energy conversion to supply up to 850 W from a relatively short chassis. Tight voltage regulation and low ripple make it suitable for systems that require stable power delivery. Fully modular cables and long flat black leads simplify cable routing and improve airflow in both compact and larger gaming cases.
Suitable for
Mid to high-end gaming PCs with single or multiple graphics cards
Compact ATX builds where a short-depth power supply is required
Systems that value 80 PLUS Gold efficiency and stable power rails
When it may not be suitable
This unit is not intended for very small SFX or proprietary cases that require non-standard PSU form factors. Extremely power-hungry multi-GPU or server configurations that exceed an 850 W budget will require a higher-wattage supply.
Key specifications
Total power: 850 W
Form factor: ATX (short-depth, 140 mm length)
Motherboard connector: 20+4 pin ATX
Efficiency rating: 80 PLUS Gold
Cooling: 120 mm fan (single)
Colour: Black
Weight: 2.4 kg
Input voltage range: 100–240 V AC
How to use
Install the power supply into a compatible ATX case following the case manufacturer’s instructions, secure it with the supplied screws, and connect the modular cables to the unit before routing them to components. Attach the 20+4 pin connector to the motherboard, connect PCIe cables to graphics cards and SATA/Molex cables to drives and peripherals as needed. Ensure the input voltage selector (if present) or the outlet supports 100–240 V AC and switch on the system after confirming all connections are secure.
What to consider before purchase
Measure available PSU depth in your case to confirm the 140 mm length fits your build.
Check total system power draw to ensure 850 W is sufficient for CPU, GPU, and peripherals.
Confirm the provided cable types and lengths match your motherboard and drive layout.
Usage recommendations
For balanced cooling and cable management, use the modular cables provided and route GPU and motherboard power cables along the case edges. Maintain good airflow by keeping dust filters clean and ensuring the 120 mm fan intake/exhaust is unobstructed.
