Outlaw 7140 Power Requirements

Outlaw 7140 Power Requirements - 03/20/17 02:16 PM

Saving my pennies for a 7140 and while I wait impatiently, I have a question about power requirements. My current setup (Oppo BDP-93, Denon 2313ci, Toshiba 47" screen) is all drawn through a UPS for power conditioning and spike/surge protection.
I'm guessing that attaching the 7140 to that as well might not be the thing to do if I want the performance I'm looking for (not to mention overdrawing the UPS). Sort of like sucking through a straw and expecting the flow of a fire hose. Everything from that side of the room is all on one breaker in any event, so I can't avoid pulling from the same source no matter what I do. Is the 7140 OK to be plugged in without protection or would standard rules of caution apply to it as well?

Depends on the power rating of your UPS. If it's rated for the same (or greater) power rating than the wall outlet then you should be fine although with the 7140 drawing a max of 1440 watts you should probably do the math and see how close you are.

How often are you really going to max out the amp though? I'm thinking you'll be fine.

Typically a wall outlet is rated for 1800 watts for a 15 amp circuit and 2400 watts on a 20 amp circuit. I would not use a UPS to power any amp of the size you are looking at. It is unlikely that you are ever going to push the 7140 to its limits for power output and thus you won't approach the power capacity of the outlet, However, it is always a good idea to have something protecting your system from lightning and other disturbances on line voltages. What many folks don't realize is that both the ground and the neutral are tied together at the breaker box and when lightning hits close to your house that path is wide open to your equipment. That is why I use power conditioners to protect my system because lightning is the destroyer. Powering your low draw equipment from a UPS is probably fine but the current draw from an amp or a sub may be a bit much. Take a look at the APC-H15 and similar equipment.

Maybe something like this?

or this:

Makes sense. I can leave my other stuff on the existing UPS circuit and run the 7140 through one of the above.

Thanks for the feedback folks!
