UPS not strong enough to keep Computer on after electricity failure

[arth]

Hello everybody,

I have a computer:

Core i7-2600 CPU 3.4Ghz
8 GB DDR3 RAM
Thermaltake armor a60 mid tower case with 3 fans one of them LED.
Nvidia GTX 460 1 GB

This computer is connected to a 1000VA UPS, im not sure how much the PC consumes but I think the power supply is thermaltake 600W.

My issue lies here:

When the electricity goes off and Im playing a game with heavy graphics, the UPS can't keep my PC on for 1 sec, it immediately shuts off. However when Im just surfing the web, the UPS can keep my PC running for 15 min.

What am I missing here ? If the power supply of the PC is 600W it shouldnt consume more than that right ? Do I need to get even a bigger UPS ?

I appreciate your feedback

How many Ah (ampere hours) can the UPS store?

Isn't it called PSU and not UPS? Isn't UPS a delivery company? :P

Un-interrupted Power Supply, a unit designed to store electricity and run any computer/s its connected to in case the power goes out.

It's a UPS, Uninterruptable Power Supply, my spelling might be off. Basically allows you to keep running your PC when their is a blackout. So you can safely turn off components and the like.

On empty desktop power consumption is under 100W, possibly even below 50W. While you have game running and graphics card at 100% load it goes to almost 300W. 600W on the PSU just means maximum load, not average load.

Uninterruptable Power Supply. It is basically a box with some lead-acid batteries in it that keeps the connected appliance running even in the event of a black-out, and they can also be used to "clean" the power, eliminating minor surges or dips in the electrical current which adds another layer of protection to the device.

good chance battery in ya UPS may be dead also.....

UPS stands for Uninterruptable Power Supply. Its basically an external backup battery usually built into a surge protector.

PSU stands for power supply unit. Its the device inside your computer which converts the alternating current from your wall socket into direct current that your computer can use.

I love how in the 30 seconds or so it took my to type my explanation of what a UPS was like 4 other computer nerds jumped on it

I am curious as to how bad the electricity is where you're at Arth. I mean, I know a UPS can be a good thing for lots of reasons, but when you say things like

You must have some bad electricity!

what is the exact model of your UPS?

You have some bad electricity! I suggest getting Corsair electricity, quality stuff.

Could be testing. I did try to pull my UPS off the grid and see how long it actually runs. Only way to know for sure how much time you have to save your stuff when real powercut comes.

I'm not really sure, how can I know ?

[Butler to Baby Sloths]

The label or the manual should tell you.

I would guess that is why people are asking for actual details, so perhaps actually providing such things as the capacity would help.

Edit: the following might prove useful.

You can calculate the estimated running time from the ampere hours the device can store, the voltage of the output and the wattage that the device draws from the UPS.
