These compact APC uninterruptible power supplies won’t be able to keep your gaming PC running at full throttle during a power outage, but they can provide enough juice to power NAS enclosures, external hard drives, or even your home networking gear during a power outage, at least until you can get everything powered down safely.
Both are $5 off when you clip the on-screen coupon, but the $52 model is more powerful, and includes a USB port.
