Power supply DeepCool GAMERSTORM PQ850G 850W, 120mm fan, Fully modular, 80+ Gold, ATX 3.1, black

DeepCool GAMERSTORM PQ850G is an 850W ATX 3.1 power supply engineered for desktop computers that require stable, efficient power delivery. The unit integrates a 120mm fan for active cooling, fully modular cabling to simplify installation and cable routing, and 80+ Gold efficiency to reduce heat and energy loss. Designed with modern gaming PCs and workstations in mind, this black PSU supports high-performance components while keeping system cable management compact and accessible.

Advantages

The power supply offers high conversion efficiency with an 80+ Gold rating, which helps maintain lower operating temperatures and improved energy use under load. Fully modular connectors enable tailored cabling for cleaner builds and easier upgrades. A 120mm fan provides regulated airflow and quieter cooling compared with smaller fans at similar output levels. Compliance with ATX 3.1 ensures compatibility with current motherboards and improved transient response for modern CPUs and GPUs.

Suitable for

• Gaming desktops with mid-to-high power graphics cards
• Workstations for content creation and 3D rendering
• PC builds prioritizing neat cable management and modular wiring
• System upgrades requiring ATX 3.1 compatibility and stable multi-rail power

Key specifications

• Rated output: 850 watts continuous
• Efficiency certification: 80+ Gold
• Form factor: ATX 3.1 compatible
• Cooling: 120mm fan with automatic speed control
• Cabling: Fully modular cable design for PSU-to-component connections
• Protection features: standard over-voltage, under-voltage, over-current and short-circuit protections
• Color: black chassis

How to use

Install the power supply into a compatible ATX chassis following the case manufacturer’s installation instructions. Connect only the required modular cables to the PSU to maintain tidy cable routing. Attach the 24-pin motherboard connector first, then the CPU 8-pin (or 4+4) connector, followed by GPU and storage power connectors as needed. Ensure all connections are fully seated and secure, and verify that the PSU switch (if present) is off before connecting the mains power. After powering on the system, monitor for stable boot and proper fan operation.

Recommendations

For reliable operation, keep ventilation unobstructed and maintain dust-free surroundings. Use high-quality modular cables provided with the unit or manufacturer-approved replacements. When planning a high-end GPU or CPU upgrade, allow headroom above peak system power draw to preserve efficiency and reduce stress on the PSU.
