Hey guys
I'm thinking of buying an APC UPS of Output Power Capacity: 405 Watts / 700 VA and Nominal Output Voltage: 230V
I know nothing about wattage and stuff like that and i need your assistance whether the ups can hold the power i want. I have:
my pc has 450w PSU
3x4gb ram cl7
athlon x3 3.4ghz
20 inch lcd screen
2 speakers of 120w output power and 60w power consumption
external soundcard of 12V DC power input
I feel i'm asking much but i believe there must be an experienced person who might know if i can connect all these to that UPS

Hi
I have a couple of computer systems connected to APC UPS of that capacity and they work fine.
In fact one of the systems has a 27" Dell monitor ,550W power supply and a 660Ti graphics and it only draws 260W.
If the APC is the one that looks like a power block then I would suggest that you plug the speakers into the surge protected sockets and not the battery maintained ones ,this means that they will go off if you have a power cut but the UPS will keep your computer running longer.
