I will be equipping it with a HX1050 PSU. I'm thinking of purchasing the CP1500PFCLCD would this be enough to power my whole rig or is my PSU wattage too big or would the UPS only take into account the actual load that's being used at the time. Hope you can help thanks
I'm no expert on PSU sizing, but I think you are going a bit big if you don't plan to add in anything later on and I also have seen it mentioned a few times that those calculators are usually pretty wrong and I believe overshoot the requirements.
If you dont get much of a response here you may want to do a separate thread to look over your build plans and likely someone with PSU experience will give good suggestions.
In regards to the UPS, it will only use the actual load that the PC is consuming plus anything else plugged into the surge side so maybe a monitor and modem which isn't much extra.
In the event of a power outage, as long as the true used power is under the rated wattage of the UPS, then you will be good to go.
Run times will vary depending on power used, but the 1500 should give you a good chunk of time while under load to close out and save anything.
On idle it will likely be good for 20 minutes or so.
I like the CP units and think you have a good one chosen, but yes I would get feedback and reconsider the PSU size.
