Compact 850W ATX 3.1 unit
The Rosewill VMG850 is an 850W ATX 3.1 compatible power supply built in a 140 mm deep chassis. Its fully modular design and 120 mm FDB fan suit builders fitting a high-wattage unit into restricted space. The single +12V rail and 80 PLUS Gold certification target systems that need steady, efficient delivery.
Native 12V-2x6 cable and modular set
A dedicated 12+4-pin 12V-2x6 connector ships attached to a native PCIe 5.1 cable, removing adapters for new graphics cards. Three 6+2-pin PCI-E leads, two 4+4-pin EPS cables, eight SATA connectors and four peripheral plugs cover storage and CPU power without surplus cables crowding the case.
Excursion headroom and hold-up limits
The platform allows up to 235% total power excursion and 300% GPU power excursion for short bursts, while minimum hold-up time sits at 16 ms. Efficiency peaks at 85% under typical load, so sustained draws near the 850 W rating will generate more heat than lower-load scenarios.

商品問答
Will the 120mm FDB fan need replacement after years of continuous operation?
The fluid-dynamic-bearing fan is rated for long service life; no user-serviceable parts are inside, so replacement would require a full unit swap if the bearing ever wears out.
What thermal limit appears first when the 850W output is sustained for hours?
The 120mm FDB fan ramps up to move heat through the large vents; the over-temperature protection will trip before any component exceeds its safe operating point.
How loud is the 120mm FDB fan and how much heat does the unit exhaust when running all day at typical load?
The fan runs quietly at low loads and increases speed only as needed; the steel shell and large vents dissipate heat efficiently so case temperatures stay manageable during extended use.
