Related Questions and Answers

Q: 1. 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.

Q: 2. What is the battery life after power is disconnected?

A: There is no simple answer to that question, as it depends on what the load is. It could be 30 minutes or it could be 5 minutes. A small, low power computer with the monitor not on battery might last 30-40 minutes, where a PC with a large power supply, high power video card, 4 hard drives, and three 27 monitors all connected to battery will go pretty fast. If you know the actual power requirements of your connected gear, you can approximate with your own math. If unsure, get a bigger unit.

Q: 3. Can B&H supply a 220v version of this or something comparable? If so, kindly send a link. Thanks.

A: Unfortunately, we do not have a 220v UPS.

Q: 5. can this be mounted underneath my standing desk's tabletop?

A: We do not currently carry a mounting bracket for this UPS, but it may be possible to mount the CyberPower SL700U underneath a desk with hook and loop fasteners or similar hardware.

Q: 6. Can I plug in a power conditioner to this (Furman SS-6B Power Strip) or would that be redundant, or cause a problem? I’m in residential with power issues that are causing odd hums in audio recordings, and the electrician says a UPC is the way to go, but the studio engineer says a power conditioner is necessary.

A: I'm an electrician and concur with the other answers, you need to look into grounding issues, specifically what's called a "ground loop". As for the UPS, it won't fix this issue, it fixes voltage and power factor issues as well as backup power of course, but it won't hurt anything either. They do make "ground loop isolators" that may do the trick, but sometimes won't help either.

Q: 7. Does this allow remote monitoring/email alerts?

A: Hello David, Yes this unit will support remote monitoring/email alerts with the addition of the optional RMCARD205.
