UPS always overloads and shuts down

[Shivam15]

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

SEAGATE BARRACUDE 1 TB ---- HDD

CRUCIAL BX 100 ------ SSD

2 CASE FANS AND 1 WLAN CARD



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???

Hi
This may be a stupid question but did you connect the battery when you got it,they are normally shipped with the battery disconnected.

No there were no instructions for that. It was just one unit and the ups provides backup sometimes like 2 out of 5 times that too when am just using youtube or something. So that means batteries are there.

Really a shame that a 1000 VA ups cant support a 500 w pc. Maybe my unit was the faulty one

Any overclocking?

nope no overclocking. Everything running on stock frequency

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://

Try switching the PSU, it might be the culprit for the resets.
