APC Smart-UPS C SMC1000IC review

The SMC1000IC is a line-interactive UPS rated at 1000 VA / 600 W. With a 600 W rating and 9 min 9 s of runtime at that full load, it suits a small homelab, a desk-side server or a compact rack where you want protection and a controlled shutdown more than hours of backup.

The output is pure sine wave on battery. Owners praise this because it suits modern power supplies with power factor correction. That is a reasonable point in its favour if your NAS or mini server uses one, since the UPS keeps feeding it a clean waveform when the mains drops.

The topology is line interactive, not online double-conversion. The manufacturer lists a typical transfer time of 6 ms and a maximum of 10 ms. The input voltage range is 180-287V.

The unit has an RJ-45 serial port, a USB port and a SmartConnect Ethernet port. APC's PowerChute Business Edition software handles unattended shutdown over a serial or USB cable. That covers machines where you can install the software.

There is one gap you should know about. No source confirmed that Synology, QNAP, TrueNAS or NUT recognise this unit over USB HID. If your NAS relies on its built-in UPS support for automatic shutdown, check compatibility with your platform before you buy.

Owners like the LCD. It shows load, runtime and input voltage, which helps when you are sizing what to plug in.

APC publishes 9 min 9 s at the full 600 W load. Owners raise short runtime as a complaint and say it limits the unit to protection and shutdown. With a runtime figure given only at full load and that owner feedback, treat this as a unit for riding out blips and shutting down cleanly, not for working through long outages.

The battery is sealed lead-acid and built in. APC lists the replacement as APCRBC142 and describes it as user-replaceable, with an expected life of 3-5 years. Plan for a battery swap within that window.

Some owner feedback comes from the US 120V model, so treat comments on runtime and display as general rather than specific to the UK unit.

There are eight IEC 320 C13 outlets. Certifications listed are CE, GOST, UK PSTI and VDE.

The unit measures 439mm deep, 219mm high and 171mm wide, and weighs 17.27kg. That is heavy for something you might lift into a rack or onto a shelf, so plan the placement.

The manufacturer states a 2-year warranty. One retailer claims a lifetime warranty, which conflicts with that. Go by the manufacturer's figure unless the seller confirms otherwise in writing.

The SMC1000IC gives you a 600 W line-interactive UPS with pure sine output, eight C13 outlets and a replaceable battery. The weak points are the short full-load runtime, the unpublished half-load figure and the lack of confirmed USB HID recognition by common NAS platforms. If you can run PowerChute, or you confirm your platform supports it, it fits the job.
