Related Questions and Answers

Q: 1. can you power an Aputure 300x LED light with this?

A: Yes, the CyberPower BL1450U Battery Back-UPS can provide enough power for the Aputure 300x.

Q: 2. If my PC has a 1200 watt Power supply will this be strong enough at 900 watts? Is this a pass through design?

A: The 900 watt rating is how many watts it will deliver when on battery. It's rated at 1500 watts pass-through when on line power. Even though your computer has a 1200 watt power supply, it more than likely never pulls that much. Most modern computers only draw 100-200 watts when idle or doing light tasks like email/web browsing. If you have 2-3 high-end power hungry video cards, are doing rendering or video processing, with a pile of hard drives, you could start getting up to the 900 watt limit. Buy a kill-a-watt and measure for sure. Also note that at 100% utilization on battery (drawing 900 watts) the run time is very short; maybe a minute or two. My workstation has an 850 watt power supply, a single GeForce 960 video card, i7-6700k, 16gb ram, 4 hdds and an ssd. With the router, a switch, and 2 monitors, I draw 350 watts when playing games & working on video encoding. I get approx. 15 minutes runtime. Idle it uses 75-100 watts, and a 30 min run time.
