The Rosewill VMG850 is an 850W, 80 PLUS Gold, fully modular ATX 3.1 power supply for gaming PCs and performance builds, with a native PCIe 5.1 12V-2x6 cable rated to deliver up to 600W to compatible graphics cards.
Recommended For
- PC gamers building around a current graphics card with a native 12V-2x6 power input can use the included PCIe 5.1 cable instead of relying on a separate adapter; community build discussions mention the VMG850 alongside modern GPU configurations.
- Builders with limited PSU-length clearance in an ATX-compatible case can consider it: its listed 140 mm length is shorter than many standard-length power supplies, while still providing 850 W.
- DIY builders who want to route only the cables their system needs can benefit from its fully modular design, particularly in a gaming build with a modern GPU and multiple storage devices.
- Cost-conscious gaming-PC builders comparing 850 W Gold units may find it worth considering; community discussions include it among options for modern gaming builds, while noting that model-specific independent testing is limited.
