Lowest price of all time on Amazon. 1500VA pure sine wave UPS with detachable LCD screen for desktop monitoring and RGB lighting to match your gaming rig. May seem a bit gimmicky, but why not?? Includes USB hookup for free monitoring and shutdown software. I bought one of these a couple years ago and the first one Amazon sent was defective, but the replacement worked great and I’ve had it since then. Super quiet as well when not running on battery, and Tripp Lite is a reputable brand.
