Windows 10: Does a HP 180 W PSU have the capability to run three large screens?

I am endeavoring to determine the load on my power supply as a first step in in sizing a new Battery Back-Up Power Supply.

That thought led me to purchase a Kill-O-Watt meter. I have been thinking that I would start by measuring the loads of my current components: Computer alone, then add monitor 1, then replace it with monitor 2, then add up the values to get a total load. Maybe this is not a good take?

I am using two large screen monitors now without any noticeable decay in performance.

Ultimately I would like to add two more monitors and a battery back-up with a significant run times ideally an hour or more.

Digging in I have been reading up on PS's.

It occurred to me that I may be on a Fool's Mission with this computer?

I will appreciate guidance on the measuring and sizing and determining the limits of my current machine's power supply.

Thanks for any thoughts.

:)

Will a 300 W video card work with a 270 W PSU ?

I notice that the other posters missed an essential point: you write that your PC requires a low profile card. A full height card won't fit at all.

If you need a low-profile GT 710, they exist:

The card doesn't need an auxiliary PCI-E power connection. The maximum power used by it is 25W. Your CPU (Intel E7400) has a TDP of 65W. I doubt that you'd need a 300W PSU with that combination.

A also see that the Pavilion was sold with a GT 220 card, which needs up to 58W. (I'm not sure that the PSU is the same, but I'd bet that it is.)

A suggestion: don't sink much money into an old Socket 775 system.
