## Long description

INTER-TECH SAMA XPH-850A is an 850 W ATX power supply designed for modern desktop PCs. It features fully modular cabling, a 20+4 pin ATX motherboard connector and supports 100–240 V AC input at 50/60 Hz. The unit complies with Intel ATX 3.0 requirements and includes a 12VHPWR connector for compatibility with current PCIe 5.0 graphics cards while also supporting GPUs with PCIe 6+2 connectors.
Advantages
The SAMA XPH series achieves high conversion efficiency certified by 80 PLUS Platinum, which reduces heat loss and lowers electricity consumption. An intelligent fan control regulates the 120 mm fan between 0 and 1600 rpm according to temperature, balancing effective cooling and quiet operation. The PSU incorporates DC/DC conversion and multiple protection circuits for stable voltage regulation and protection against overcurrent, overvoltage, undervoltage and short circuits. A five-year full warranty is provided.
Suitable for
Gaming and high-performance desktop PCs requiring up to 850 W
Systems with PCIe 5.0 GPUs (12VHPWR) and legacy GPUs using PCIe 6+2 connectors
High-efficiency builds where low standby and operating losses are important

How to use
Install the power supply in a compatible ATX case, secure it with screws and connect the 20+4 pin ATX cable to the motherboard. Use the fully modular cables to connect storage devices, fans and the GPU; for PCIe 5.0 graphics cards use the 12VHPWR connector, or use PCIe 6+2 cables for legacy GPUs. Ensure AC mains connection matches the input range (100–240 V) and verify all connections before powering the system. During first startup monitor system voltages and fan operation to confirm stable operation.
Usage recommendations
For reliable performance, allow unobstructed airflow around the PSU intake and avoid routing modular cables across the fan. Match the PSU capacity to your system’s continuous power draw rather than peak spikes, and update GPU power connectors according to the card manufacturer’s instructions. Keep firmware and system components up to date and maintain dust-free airflow for long-term stability.
