Compact 850 W SFX power supply

This Vetroo SFX unit delivers 850 W of continuous power in a 4.9 x 3.9 x 2.5 inch chassis. It carries 80 PLUS Gold certification and meets ATX 3.1 and PCIe 5.1 specifications. A 90 mm FDB fan provides cooling while keeping noise low. The fully modular cable set reduces clutter in small-form-factor builds.

Suited for high-wattage SFF and ATX conversions

Builders fitting a power-hungry GPU into a mini-ITX case or adapting the unit to a standard ATX chassis with the included bracket will find the connectors and clearance they need. Systems that require more than three SATA power connections or additional PCIe cables beyond the one 12+4 pin and two 6+2 pin plugs should look at a different unit.

Single 12VHPWR connector limits multi-GPU use

The power supply includes exactly one 12+4 pin PCIe 5.1 connector alongside two 6+2 pin PCIe connectors. Rigs that need two native 12VHPWR cables for dual modern graphics cards cannot be supported without adapters, which are not recommended for sustained high loads.

Questions about this item

Will the included SFX-to-ATX bracket let me mount this 850SFX unit in my older ATX case?

Yes, the supplied bracket adapts the SFX form factor to standard ATX mounting points so the 850W unit fits older full-size chassis.

How can I verify the 90mm FDB fan is running quietly after installation?

Listen for low-noise operation at idle; the fluid-dynamic bearing fan spins only when needed and stays near silent under light loads.

Does the box contain the 12+4 pin PCIe 5.1 cable and the three SATA power cables, or must I buy them separately?

All modular cables including the 12+4 pin PCIe 5.1 connector, two 6+2 pin PCIe cables and three SATA connectors are included in the package.
