It's the motherboard - the processor would have violently overheated if it would have drawn so much power.

UNINTERRUPTIBLE POWER SUPPLY


UPS – UNINTERRUPTIBLE POWER SUPPLY
Uninterruptible power supplies provide protection against mains power faults to computer equipment.
These faults include voltage spikes/interference, over voltage and under voltage, mains supply interruptions and surge protection etc.
These faults can cause computer and electronic equipment that are connected to an unprotected mains supply to malfunction and/or sometimes fail.
A common problem, when burning Cds, DVDs etc. any slight power interruptions to the burning process will halt the recording process and rendered the disc useless.

There two type of Uninterruptible Power Supplies
The lower powered and cheaper type UPS are switch-over types, when the mains supply fails, the UPS switches over to the batteries and inverter in milli-seconds which then supplies mains power to the computer and peripherals. A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails.
NOTE : The mains waveform from these UPS is a pseudo sine wave (i.e. not a true sine wave).
The true UPS types are usually the higher KVA units (over 1500 VA) that supply continuous mains power. The mains power is connected to a charger which charges the batteries and then the inverter draws power from these batteries and converts it to true sine wave mains power to the computer equipment, therefore there is no switch over time lag when the mains supply fails.

SUA3000RMI2U won't carry load


Did you run this test without AC input?
Also what happens when you cut off the AC mains without any load connected to it? Will the UPS continue to run or does it switch off as well?

When I switched on my UPS of my PC, I heard a big bursting sound. My Main Switch got tripped off and I had to switch it on. After that when I switched on my UPS, there was no problem and my PC works fine....


It is an audible alert that it has come 'online'. This is the same sound you hear when the wall power goes out and your UPS supplies the power to your computer. It is meant to get your attention, in order to deal with any problems that may have surfaced.

Good luck!

I don't understand if my new UPS(Mercury-Elite650Pro Line Interactive) is getting charged or not. Do I ONLY switch on the main power supply?If I also switch on the multiplug adapter, orange light is on....


Yes. you need to switch on the power plug to allow the charge. refer to the user guide, usually an orange light is showing the power ups do charge activity.

Can i have all the basic details of UPS system


UPS come in two types, lower powered cheaper types are usually switch over power.
These units senses a power outage and then switch over to the battery power to generate mains supply. The switch over occurs in milli-secs and does not affect the computer.
True UPS types constantly run off battery power to generate mains supply so there is no switch over time lag. These units are higher powered and higher costs units.

Both type of UPS have the same components.
Battery charger.
Batteries
Inverter that converts battery voltage to mains voltage
Electronic controls

My PC is geting switch off when Power flatcutations come,even ups is connected and no back up comes from UPS, after that UPS takes >4 seconds to switch to mains supply.


A four second transfer time is way too long by at least an order of magnitude. There is no way the power supply in a PC can maintain for that long a time.

If you are in a real critical environment I would recommend going to a UPS which runs continuously and runs off a battery which is charged whenever utility power is available. That way there is no transfer time.
These offline units are harder to find however.

I suspect your UPS system is defective.

How to charge ups for pc's


Your PC connection must always come via UPS, and your UPS will always keep charging.

UPS Power cable should be connected to DC, and your PC power cable should be connected to UPS.

And this way your PC will always be safe.

Dc bus faulty


Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. There maybe one battery in a set of batteries that is faulty and causes the whole battery system to fail and indicate a battery fault.

These lower powered and cheaper KVA type UPS are switch over types, when the mains supply fail, the UPS switches over to the inverter in milli-seconds which then supplies mains power but the power waveform is a pseudo sine wave (ie not a true sinewave. A faulty inverter circuit won’t deliver power when the mains supply fails.

The true UPS types are usually the higher KVA units (over 1500 VA) that supplies uninterrupted mains power. The mains power is connected to a charger which charges the batteries and the inverter draws power from these batteries and converts it to true sine wave mains power therefore there is no switch over time lag from the mains to the battery.

When UPS is shut down the lights go out on front pannel but power remains on plugs. It is coming from the AC side not the battery.


The UPS has a fauly/problem.
If your UPS is approx. 600VA, then it is not a true UPS unit but a switch over type. When the mains power fails the UPS switches over to the battery and inverter in milli-secs to provide mains power.
If you turn off the mains supply and shut down your UPS, but you are still getting mains power, then there is a fault with the switch over circuit.
You need to get this unit serviced.
