Basically question is in the title. (all text below is with PSU 800+W and UPS 630W)
My problem is (and I havent found an answer anywhere) that I dont know if the UPS takes priority over PSU when supplying the PC when the electricity is working (as in, the time when we dont need UPS to do anything).
I have a gaming PC, just GPU, CPU and monitor combined account for 450W, with all the other things connected, i get over 700W while using a 800W or 850W PSU. Thats all fine.
BUT, If I use UPS that has lower wattage than the PSU...what is going to do all the power supplying when electricity works? PSU with its 800 or850W meaning I will never have problems when electricity is working or will it get limited to the UPSs 630W meaning it might shutdown?
Wall socket => UPS (doing nothing, just transfering what PSU needs) => PSU (supplying its own 800W) => "PC" (getting upto 800)
Or
Wall socket => UPS (sending only 630W) => PSU (supplying only 630W) => "PC" (getting only upto 630)
I know the usual mantra "Get UPS to match your maximum power usage", I dont care about that, I really dont care about the borderline cases where it might shutdown when electricity is out, I only care about when electricity is working. What is used as "maximum" being supplied, PSUs 800 or UPSs 600W.
PS: CyberPower UT GreenPower UT1050EG-FR , the price jump between 630W to 720W or 900W where I live is about 2-3x
