The FSP Vita GM 850W power supply measures 140x150x86mm (LxWxH). This is a small power supply which will suit a wide variety of large and small cases on the market today.
The fan is underneath a solid grille on top of the unit. It looks quite stylish, but it's quite a thick grille – hopefully it won't interfere too much with airflow when we get around to testing.
One side of the power supply is home to a vented panel, a power connector and power switch. As mentioned, there is no semi-passive fan button on these units.
The modular bay on the other side of the power supply is split across several rows, with each connector labelled. On the far left is a triple row of peripheral connector slots.
The FSP VITA GM 850W delivers 20A via the +3.3V and +5V rails and 70.83A via the +12V rail.
