Product information

Description

SAMA Gears P850 White is an 850 W ATX 3.1 power supply designed for desktop PCs. It delivers high efficiency with 80 PLUS Platinum certification and offers a fully modular cable system to simplify cable management and create a cleaner build. The unit includes a native PCIe 12V-2x6 connector and cable for compatibility with next‑generation GPUs, a 140 mm ECO fan with Fluid Dynamic Bearings for quiet cooling, and uses 100% high‑quality Japanese capacitors to ensure stable operation under load. The power supply is available in white and supports universal AC input (100–240 V).

Advantages

The P850 provides high energy efficiency to reduce waste and heat, while ATX 3.1 compliance and tight load regulation (±1%) ensure stable and reliable power delivery for modern components. Fully modular cabling reduces clutter and improves airflow. Additional design details—such as dual rubber pads on the fan corners and a low‑noise 140 mm FDB fan—help minimize vibration and acoustic noise. Built‑in protections cover over voltage, under voltage, over current, over power, short circuit, over temperature, surge & inrush, and no load conditions. A 10‑year warranty supports long‑term use.

Suitable for

High‑performance desktop PCs with modern GPUs
Compact builds that require a high power density
Systems where quiet operation and clean cable routing are important
PCs requiring ATX 3.1 compliance and tight voltage regulation

When it may not be suitable

This 850 W model may be excessive for very low‑power office or HTPC systems where a lower wattage, less expensive PSU would suffice. Also, if a system requires non‑standard connectors or proprietary PSU form factors, this standard ATX supply will not fit those requirements.

Key specifications

Output power: 850 W
Efficiency rating: 80 PLUS Platinum (approx. 92% typical)
Standard: ATX 3.1 compliant
Input voltage: 100–240 V AC
Connector: 24‑pin ATX motherboard connector
Native PCIe connector: 12V‑2x6 (PCIe 5.1 compatible)
Cooling: 140 mm ECO fan with Fluid Dynamic Bearing (FDB)
Capacitors: 100% Japanese electrolytic capacitors (105°C rated)
Regulation: load regulation ±1%
Protection features: OVP, UVP, OCP, OPP, OTP, SCP, surge & inrush protection, no load protection
Form factor: ATX (compact compatible)
Color: White

How to use

Install the PSU into a compatible ATX chassis, secure it with screws and connect the 24‑pin ATX cable to the motherboard. Use only the required modular cables for CPU, GPU and drives to minimize clutter. Verify AC input range matches mains supply (100–240 V). Ensure adequate airflow around the 140 mm fan and route cables to avoid obstructing other components. After connections, power on the system and check stability and voltages in BIOS or with monitoring software.

What to consider before purchase

System power requirements and headroom for peak GPU/CPU loads
Compatibility of the native 12V‑2x6 PCIe connector with your graphics card(s)
Case size and mounting space for an ATX power supply
Preference for white color to match your build aesthetic
Need for a long warranty and high‑temperature rated capacitors

Usage recommendations

For reliable long‑term operation, keep the PSU clean and ensure good case ventilation. Use only the supplied or compatible modular cables and periodically check connections and fan operation. This unit is best paired with modern high‑performance GPUs that support the native 12V‑2x6 connector.
