SFX 850W ATX 3.1 unit

This Vetroo power supply delivers 850 watts in the compact SFX form factor and meets the ATX 3.1 and PCIe 5.1 specifications. A 90 mm fluid-dynamic-bearing fan handles cooling while keeping noise low. The package includes an SFX-to-ATX bracket so the unit fits both mini-ITX and standard ATX cases. Full modular cabling lets you install only the leads your build requires.

Small-form-factor builders and GPU upgraders

The SFX footprint and included bracket suit compact cases and allow easy migration to a larger chassis later. One 12VHPWR connector plus two 6+2-pin PCIe plugs support current and previous-generation graphics cards. Builds that need more than three SATA power connectors or that require additional PCIe cables for multi-GPU arrays should consider a unit with higher connector counts.

Single 12VHPWR connector

The specification that decides fitment is the presence of exactly one 12+4-pin PCIe 5.1 connector. If your graphics card draws power through two such connectors, or if your motherboard requires dual EPS cables, this model will not meet the requirement without adapters that add bulk and failure points.

Questions about this item

What does the ATX 3.1 standard cap the 12VHPWR connector at in practice?

The unit includes one 12+4 pin connector built to the ATX 3.1 specification and PCIe 5.1, delivering up to 850 W total across all rails

What does it physically need to fit or mount in a standard ATX case?

An SFX-to-ATX bracket is included so the 4.9 x 3.9 x 2.5 inch SFX body can be secured in a regular ATX power-supply opening

How is it installed, and which step do builders often get wrong?

Mount the PSU with the bracket, connect only the fully modular cables your build needs, and remember to seat the 12+4 pin GPU cable firmly until it clicks
