APC Power Saving Back-UPS 750 with a 1000watts Power Supply

InfiniteLoop · Mar 8, 2016

Hopefully I'm asking this question in the right thread. I bought a used APC Power Saving Back-UPS 750, I have a computer with a 1000 watt power supply and don't think I'm drawing the full 1000 watts. I have a 50 dollar video card, no optical drives, an i7 processor.

Is it okay connecting my computer to this UPS?

On their website, it says :Output power capacity 450 Watts / 750 VA Max Configurable Power (Watts) 450 Watts / 750 VA

.. but I'm not very hardware savvy unfortunately

Here's a link to the official site I found: http://www.apc.com/shop/us/en/products/APC-Power-Saving-Back-UPS-750/P-BE750G

I'm just hoping I'm able to use it. Thank you very much in advanced.

You certainly have an overkill of a PSU for that system that you are running.
Bear in mind that the 1000W is what is provided by your PSU to your PC and is in Direct Current.
Your PSU draws Alternating Current from the UPS and will not draw anywhere near the 450 Watts that the UPS is able to supply, even under a hard load.

Thanks for the detailed answer! I'm glad I'll be able to use it safely with my system.

No problem.
Bear in mind that it is a low capacity UPS and as such will not be able to keep your system running for too long in the event of an outage (maybe 15 minutes or so).
So, if power goes out, I always recommend start saving what is being done and then shutting the system down in an orderly way.
