How many UPS can I plug into one power socket (in India)

[Anonymous user]

This is my first post here, so pardon me if I make any mistakes.

I have 2 APC UPSs

1) Back UPS ES 500 (old one)
2) Back UPS RS 1100 (New one)

I've purchased the new ups to support my system having AMD Phenom 955 BE Quadcore processor (No overclocking), 1GB DDR5 graphics card (No overclocking) and Antec 500W 80+ Bronze SMPS. As this system was overloading my older UPS which has an output of 500Va, 300W i purchased the new one which has 1100Va, 660W output.

Now my question is whether I can plug both the UPS into one power supply (which is 230V, 50Hz in India) using extension cords? With the new UPS I'll run my system, 20 inch LED monitor and 5.1 speakers and from the old one I want to run my modem/wireless router and printer. Does plugging 2 UPSs into one power supply cause any damage to my system/peripherals or to the power supply?

Hi cyber2222, we do not typically recommend the use of extension cords with any ups system (as it can effect the surge protection of the ups itself). As far as the power supplies go ( I assume you mean the wall AC power?) you should be able to put more than more ups on the same circuit in your household (given they do not overload the circuit). Also make sure that you do not plug the UPS's into one another (i.e. each use should be plugged directly into its own wall outlet). Hope this helps, Rob.

Thanks Rob. I'll not use the extension cords anymore.
