Okay, so the PSU of the PC that I'm going to buy has a generic PSU. I also have tried Extreme PSU Calculator and have shown about 250W on 100% usage. I don't know how accurate that is so I hope someone can give me some insights on how much power (Watts) this Rig can consume:
Its the UPS the OP seems to be worried about for that.
Yep, you are right. The UPS will power this config for a short period of time. Personally, I connect my displays to the non-power (surge only) side of my UPSes. Shouldn't be a problem unless you live somewhere with lots of power outages.
Wow! Less than 200W? Did not expect that. It may seem that you guys made a mistake reading. I don't have a UPS yet. I only have an Automatic Voltage Regulator (AVR) that is rated 500W. It has 4 sockets. 1 - 110V and 3 - 220V. I plan to plug the CPU and CRT monitor in the 220V Sockets. Nothing else gets plugged in the AVR.
So, If I base it on the insights here. It means my 500W AVR should be fine with my rig + monitor. Right?
