hi i am thinking of buying my first ups
but i have a few questions my biggest concern is electric bill
i stayed away from a ups purchase a while back when i saw a youtube comment from someone that said a ups will actually use alot of power and result in higher electric bill

also i was thinking of buying a apc ups be750g 10 outlets

i plan on conecting my synology ds209 nas, time machine, 2010 21.5" imac, and another external hdd to the 5 battery outlets and then connect my switch, tv, 5.1 sound system and usb hub to the other outlets

i just wanted to know if that is a ok setup for the ups and if that ups will be good for me

i have a couple other devices like a sony shelf system, harmony control dock, wdtvlive, directv box and printer but i think i will buy a surge protector for those or maybe even buy another apc ups with less outlets or just two be750g ups

any advice would be great
 
I currently use the BE750G to backup my HP EX485, cable modem, and wireless router... and as it stands, it's at 40% load (a little over 200W). I'm not too sure how much the iMac draws... but just be aware that this UPS is only capable of 450W. A UPS will start beeping / alerting you when it's at 80% load (360W).

Look at what each of your devices draws (in watts) and make sure it adds up to under 360W. Another way to tell is to install the PowerChute software. It'll tell you the load on the UPS. As long as you are under 80%, you should be fine.... and obviously the lower the load, the longer the uptime for all devices connected.
 
There are several outlets on the UPS, some outlets protected by battery backup and some only via surge protection (I think the ones outlined in white are protected by battery backup).... I think the outlets should be labeled. You should be able to tell which ones are battery protected vs surge protected.

The load is measured by whatever is connected to battery backup. If you connect your nas, time machine, ext hhd, and imac into the outlets that are protected by battery backup, that counts against the load on battery. Your other devices (switch, tv, etc) are only protected via surge protection and do not count towards the load on battery.
 
o ok i only want a few items on the battery but the load means how much it can handle and not how much is in use correct?

if so i think i might go with two be750g ups

you wouldnt happen to know an answer to my electric bill question on my first post would you?

i really only want a ups incase of outage or that sort of thing we dont have outage problems in my area injust would use the ups to quickly be able to properly shutdown my imac and nas and external hdds properly to avoid data loss or damage
 
Instead of getting two ge750g... why not just get on UPS that's rated at 1500va?? Probably cheaper... but not 100% sure.

As for electric bill, I have three UPS in my house. Two 1500va and one 750va. I have not noticed a huge difference from before I used it to now.
 
Normally, the outlet is rated for the same load as your circuit breaker (15A). Using two outlets won't allow you to draw more power unless they are on different breakers, which is generally not the case for outlets in the same room.

As for efficiency, you have a good point - it would be nice to see efficiency ratings for UPS like we do for PSUs.
