PC Peripherals Power Supply and UPS conflict?

I've been having a strange issue for the past couple of days. Before I delve into the details, I'll list out my system config.

Core i7 860
Gigabyte GA55 UDR3
Corsair Value RAM 4GB
MSI Twin Frozr II 6950 2GB
Asus Xonar D2X
LG DVD writer
2 x 2TB Seagate
1 300GB WD VelociRaptor
Lian-Li K56 cabinet

This rig is powered by a Tagan Stonerock series 600W power supply with two +12V rails rated at 22A each.
This is connected to an APC BackUPS 500 ES UPS.

Now the issue. When I turn up all settings in Crysis and start the game, after the intro is over and Dr. Rosenthal's radio transmission begins, the UPS starts screaming its life off. The green LED goes red with a constant high pitched beep.

I researched this issue on the net and came with the following two causes.
1. The battery is dead.
2. The UPS cannot supply the system with the power required.

I'm assuming the second cause because as soon as I exit the game, everything is back to normal. Now, my questions are:

1. Is there any issue with my power supply? I think not because there is no problem with the system. But, I may be wrong.

2. If the UPS is unable to supply the power requested, then is there any workaround to this, short of plugging the rig directly to the wall outlet?

3. Any chances of frying the rig and/or the UPS without playing Crysis and just carrying on with normal downloading and other regular stuff (no gaming at all)?

4. If I have to upgrade the UPS, please recommend a suitable model which will be adequate for this configuration.

I'd like your opinions on this. Sorry for the long post.

Thanks in advance :)
 
sell that old battery inside and buy a new one.No need to buy a whole new UPS.But this applies only when your battery is dying,and not when the circuitry.

You can plug it to your wall socket and test weather any other component has gone wrong,but it's quite risky,so better be careful.may be should ask a frnd for his UPS and then test.
 
It could be either case. However this should happen only when the UPS is switching to battery power. Are there voltage fluctuations?
 
Your UPS is rated for only 300 watts max. Your system configuration easily exceeds this at full load, which is why you are have having problems gaming.

1) Your power supply is allright.

2) None that i know of

3) It will be fine without gaming

4) How about BackUPS 800 ? This can provide 540 watts which will be enough for your system. If you are budget constrained buy the BackUPS 650, but that will be a close call.

Appreciate that reply. So, now I will have to UPS hunting. I did connect with a APC UPS chat rep online to find out if there are any upgrade options available for my 500ES but apparently there are none. So this one is going to lie around at home. :(

I am looking at the APC Back-UPS 1100 with 660W rated output. I am thinking it will suffice for my current rig. Do you think it will be a little future proof? :ashamed:

The 1100va should be more then enough for powering your current computer and a 75" lcd-led or a 42" plasma.

But if you have frequent power cuts and have the need for longer back up then its best to go with a ups with external batteries such as the APC 1000UXI ,but will be expensive.

I beg to differ...It will be sufficient for the computer all right but not for the plasma as well, I am using the 1100va for my comp. if I connect my plasma, the UPS will Overload and starts giving that warning. It really is not sufficient for the TV. get a house inverter if you need to back Up a power hungry Plasma as well as your PC.....

OP: What display are you using....???

That is the over load warning...what are you trying to do...You have a 600Watts SMPS, and a 500va UPS. Ofcourse it will overload once you load the game and the system starts to consume more power as stated earlier....
 
Regarding frequent power cuts...no, there are not much. I just need a UPS to save my work and shut down. In case I am gaming, then just exit the game and shut down. I don't need more power back up than that. If I configure the system with full load on the APC site, then the 1100 can provide 4 mins of backup. But I guess that's enough for me to shutdown my system without issues. My only issue is the gaming part when the current UPS gets overloaded. I want to avoid that situation with the next. :)

I am using a Samsung P2350 LCD display and all gaming is at 1920 x 1080 resolution.

Yes, I know that is kinda moronic for me to do, but I never really paid attention to the UPS box at all. It's when it started overloading that I started paying attention to it. Yeah, I am truly :ashamed:
 
^^ I don't know how much that LCD consumes...but i think you should be fine with the 1100va.
As for my plasma takes 300Wats at max so it is not sufficient for me.

think you might be ok with the 1100va also as i dont know how much that LCD consumes but I dont think much at all.....or.....You can also use the newer 1100va/660Watts for the PC and the old 500va/300Watts only for the monitor, and you will have sufficient time to shut down the machine even while gaming.....and it will not overload anything, though you will be using two UPS.:) or you could try the 1500va/865Watts one.

But the price difference between the two ie. 1100va and the 1500va is quite significant last when i checked.
 
Thanks for the opinoins, guys. Now on to the great UPS hunt. I've had some funny experiences in the meantime while trying to find the UPS rates. I am starting a new thread for that. :)
 
The 1100VA is apparently 'currently out of stock' as told to me by PrimeABGB and TheITDepot although it is listed on their websites. The next best in terms of price is the 1000VA and that is for Rs.6555, the best price that I could get. So, the lesser the VA, the higher the price? I don't know what the difference is but the price difference to me is, well, unexplainable! :huh:

A typical 1000va house inverter from APC or some other company is around 660watt the same as the 1100va ups.
Well that depends on the plasma ,if you see HDTVTEST uk power consumption measurements they are below the 150watt figure under ideal settings.
But if you do a cold start in the event of power cut it may overload a UPS.

Is pc should consume around 400watt and even if its 200watt for a plasma,it should be within the rated specs of the 1100va UPS.
A lcd-led on the other hand will run without issues.
 
I think the price difference is because of the pure sine wave feature on the 1000VA model.

So how different is the 1000 VA model from the 1100 VA model? I mean, how is it better? The criteria I am judging by is that the 1100 VA has a max output rating of 660W while the 1000 VA has a max output rating of 600W. My point of view is not overloading the UPS which is happening right now. I will upgrade to a GTX 580 soon, so would like your opinion if I should go for the 1000VA or the 1100 VA (if available). :)
 
Adder->....you know the plasma I am talking about :) ...think you have see that thread on Hifivision also :)

Anyway, the 1000va might be the one with the USB port and Auto Shut Down feature and APC software thats why it could be
more.

For a difference between the two (square wave and pure sine wave UPSes) refer to the TE thread: http://www.techenclave.com/pc-peripherals/of-psu-ups-pfc-sine-wave-114774-3.html

Also, Tom's has an article where the first few pages will explain where a pure sine wave UPS becomes useful: Enthusiast Power Protection: Four-Way 900 W UPS Roundup : Power Protection Or Rage Prevention?

Well neither are pure sine wave,the 1000va model has the option to connect a 24v 14A APC battery pack or make your own pack.
