APC Back-UPS Pro BR1500G, US plug

Part numberBR1500G

The short answer

Backup power for a mini PC desk: the APC Back-UPS Pro BR1500G, US plug, is a UPS of 1500 VA and 865 W with 5 outlets. Its output is not pure sine, so it suits an owner who first confirms the machine's power supply accepts the simulated sine wave on battery.

Specifications

The 1500 VA and 865 W figures are the limit on what you can run from it, so add up the draw of your mini PC and anything else on its outlets first. With 5 outlets there is room for a mini PC, a monitor and a few extras. It also has USB management. The maker's own page carries the full specification.

Which mini PCs it fits

Fit here is decided by the power supply, not by a port or a slot. On battery this unit gives a simulated sine wave rather than pure sine, so a machine works with it only if its power supply accepts that.

Examples with that caveat are the GMKtec NucBox K13, the HP Z2 Mini G1a and the Lenovo ThinkCentre M70q Gen 5. For each, the reason is the same: the sine wave is simulated on battery, so check the power supply accepts it. No machine fits it without that check.

Checked against every mini PC sold on amazon.com, from the specifications we hold for each machine.

Before you buy

The simulated sine wave on battery is the real limit: the output is not pure sine, so confirm your mini PC's power supply accepts it before you rely on this unit. For a machine not named here, we have not confirmed the fit, so check its power supply yourself.

Common questions

Does the BR1500G output a pure sine wave?

No. Its output is not pure sine, and on battery it is a simulated sine wave, so check that your mini PC's power supply accepts it before you depend on it.

How much load can the BR1500G handle?

It is built for 1500 VA and 865 W, so total the draw of your mini PC and everything else on its 5 outlets and keep that total under those figures.

Can I manage the BR1500G over USB?

Yes, the BR1500G has USB management. For the details of what that covers, read the specification on the maker's own page, where the maker publishes it.
