My specs are :

AMD FX 6300 ---- CPU

ASUS M5A97 R2.0 ------- MOBO

CORSAIR CX500 ----------- PSU

SAPPHIRE R9 270X 4GB --------- GPU

ADATA 1600 MHZ 8GB ---- RAM

THE UPS I AM USING IS CYBERPOWER BU1000E

The ups is 1000 VA and the power supply is 500w, still as soon as i remove the plug from the wall outlet and with the pc turned on, the ups just gives in and shuts down. What seems to be the problem???


 
Solution
Hi
Thats a tier 4 power supply so it is pretty poor and will be inefficient probably no more than 65% so a 400 W load will mean it will draw about 600W and so may be overloading the UPS.
My advice would be to get a new power supply that is more efficient like an 80+ one preferably one from tier 1 or 2 from this list ; http://


bro everything is working quite well, when plugged into the wall outlet but as soon as i remove the ups plug from the wall socket, the ups is not able to provide any power backup at all!!
 


it is not , it is just two days old. I read good reviews of cyberpower. Does it have to do something with the load? Like my ups is 1000 va so it can output a power of 600w, Now my psu is 500w, so can there be the possiblity of my pc drawing more than 600 w of power since psu is not 100 % efficient?
 


would 800 va be okay or is it too low? also i am not sure about the power consumption of my pc. It has 500w psu but since it is not 100% efficient then it must consume more than 500w. What if it consumes more than 600w ?
