Product information

Description

The Qoltec 50350 1850 W power supply unit delivers 1850 W of continuous power and is certified 80 PLUS Platinum for high energy efficiency. Designed for high-demand systems and cryptocurrency miners, it supports an AC input of 180–240 V at 47–63 Hz, uses non-modular cabling, and includes PCIe cables for straightforward connectivity. The unit has a 60 mm active cooling fan, a noise level around 50 dB and comes in a grey finish. It is backed by a 24-month warranty and packed in an eco-friendly biodegradable box.

Advantages

The product is certified (CE, RoHS), offers a long rated service life and arrives in environmentally friendly packaging.

Suitable for

  • High-performance gaming PCs and workstations
  • Cryptocurrency mining rigs
  • Systems with multiple GPUs requiring stable PCIe power
  • Environments where energy efficiency and lower cooling noise are desired

Key specifications

  • Total power: 1850 W
  • Certification: 80 PLUS Platinum
  • AC input: 180–240 V, 47–63 Hz
  • Cabling: non-modular (PCIe cables included)

How to use

Install the power supply in a compatible PC or mining chassis following the manufacturer’s installation points and secure it with the appropriate screws. Connect the main ATX power cable to the motherboard and attach PCIe power connectors to graphics cards or other devices that require dedicated PCIe power. Ensure the AC mains voltage matches the unit’s 180–240 V input range before powering on. Maintain sufficient airflow around the unit and keep dust away from the fan to preserve cooling efficiency.

Usage recommendations

For reliable operation choose components with combined power draw below the unit’s 1850 W rating and allow headroom for peaks. Periodically inspect the fan and connectors, and use a surge protector or UPS in locations with unstable mains supply to protect against overvoltage events.
