How long will a Smart-UPS 1500 run my kit?
Roughly fifteen to twenty minutes at half load, much less if you load it fully. Send the equipment list and we will give you a realistic figure rather than the headline one.

Overview
APC Smart-UPS 1500VA — Supplied and Configured in the UK
The 1500VA Smart-UPS is the most common size we quote: enough to hold a comms cabinet or a small server and switch stack long enough to ride out a cut or shut down cleanly.

What a 1500VA Unit Actually Holds
Around 1,000W of usable load. In practice that is a switch stack with a firewall and one small server, or a comms cabinet with access points and a NAS — for ten to twenty minutes depending on how loaded it is.
- Pure sine-wave output, safe for server power supplies
- Tower (SMT1500) and 2U rack (SMT1500RMI2U) versions
- Hot-swap batteries so replacement does not mean downtime
- Network management card slot for alerting and safe shutdown
1500VA or Step Up?
If the rack is already near capacity or you want longer than about fifteen minutes, go up a size rather than adding load to a full unit.
| Deployment | Model | Usable load | Typical runtime at half load |
|---|---|---|---|
| Smart-UPS 750VA | ~500W | Around 20 minutes | |
| Smart-UPS 1500VA | ~1,000W | Around 20 minutes | |
| Smart-UPS 2200VA | ~1,980W | Around 20 minutes |

FAQs
Questions We Are Asked Most
Is there a rack-mount version?
Yes, a 2U rack model alongside the tower. Same electronics, different chassis — we supply whichever fits your cabinet.
Can it shut my server down automatically?
Yes, with a network management card or USB connection and APC's shutdown software. We configure it before dispatch if you want.
