Built around the ATX 3.1 standard, this unit combines solid performance with an accessible price point, making it a practical choice for a wide range of system configurations. The non-modular cabling design keeps things straightforward, and the all-black finish gives it a clean, no-fuss appearance that fits neatly into most cases.

Efficient Power Delivery and Protection
The BC-850 carries an 80 PLUS Bronze certification, reflecting a reasonable level of energy efficiency during operation. It delivers up to 840W on the combined +12V rail with a maximum output current of 70A, ensuring demanding components receive stable power. The unit supports a wide input voltage range of 100 to 240V at 50/60Hz, making it suitable for use in various regions. Built-in protection features include over current, over voltage, over power, and short circuit protection, helping to safeguard your components during unexpected electrical events.
