Hi ppl,

I know this isn't exactly hard drive related but it is belong near to this topic :).Last march i moved to Mexico,and in here are power problems on daily basis,1 or 2 seconds without power,voltage is jumping up and down etc.So at first i bought older UPC with nominal power 480w (around 4 years old) and changed the battery.It haven't been enough my PC always went off because battery would switch itself of when playing games.I thought it is because voltage converter itself degraded over the years.So i bought new one vica b flow 500w (cost me around 130 dollars) but this one wont even run the machine under the full load.It says overloaded and disconnect.I got desperate so start to play with it and found out that my old 480w UPC it s able to hold machine itself even under the load,without monitors and speakers when ac voltage isn't available.But the new more power full 500w will just show me overload and switch itself off.I have i5 2500k @ 4.6 ghz,water cooled,8gb ram @ 1996 mhz ,gtx 680 and 2 hdd and 2 ssd,corsair 850w psu.I did the math and it doesnt make sense max output of my pc should be no more than 450w.Is my math wrong,or just my new UPC isnt working properly?

If the 500W UPS is shutting down you are pulling over 500W. Whats the efficiency of your PSU? Try backing down your OC on the CPU, switch to an air cooler and see how much power you save.
 
It might be defective but that UPS really isn't adequate for the system. The UPS should generally exceed the rated output of the UPS and preferably, 10-30% higher (depending on PSU efficiency). 450/500 = 90%. I assume you are 110v so you'd need a 80+ Platinum rated PSU, maybe Gold, or else you would be going over the rated maximum of the UPS.
 
Thank u all that was fast...well first old one which wont switch off,it s 480w 850VA.Second the new one which is showing overload is 500w 900va.Actually,both have displays and showing load.Older and weaker which shows 3/4 of load if i switch game on and stays on.The new one 500w shows 4/4 when loading system 3/4 when idle...and if i load a game for example WOT (not exactly demanding game) shows overload for 3s and cut me off ) both are vica , unknown brand is US but very well known in here...they aren't cheap and come with 5 years warranty.So or i need more power and overload protection on old one sucks or the new got problem with output around 450w.

Your assumption is almost right,now it is 127v/128v.Psu is just bronze + it is corsair thx 850w.The thing is my hardware isn't able to max psu that is why i bought just 500w cause i need it only to cover 1s or 2s of no power so it can be maxed.But for the future i ll keep this in mind.Also i should count with other peripherals so around 100w+.

That was a typo :),it supposed to be UPC,my psu is fine.I used to have 2gb hd 6950s in crossfire that why i have 850w psu.
 
Battery likely won't last five years. Warranty probably doesn't cover those.

I have three CyberPower 1350PFCLCD UPSs.

Nope battery wont last more than 2 years with usable capacity,but that doesn't matter as one UPC is 1 day old and second has new battery 2 weeks old.I just dont understand why would 4 years old UPC (with new battery) hold under the load when it was weaker even as new and recently bought with higher output is overloading...the thing is UPC as PSU transformers are loosing around 10% capacity each year.
 
Like I said, the new one might be defective. Contact the manufacturer?
 
Yeah i ll do that i just wanted to make sure.
 
Correct me if I'm wrong but you could just get a UPS with defective battery,open it and use the circuitery to plug onto a 12V car battery?
 
I don't think so. I think the battery design is completely different so I'd expect something to go very wrong.
 
Almost all UPSes use lead acid batteries, so you can replace the battery with a car battery...sometimes. I say sometimes, because generally a large lead acid battery like a car battery requires a higher amperage to charge, and a lot of the smaller UPSes don't put out enough current to charge a large lead acid battery. However, using something smaller, like a lawn tractor battery, is usually ok. The other problem with this though is that car batteries/lawn tractor batteries can vent gasses when they charge, which can be dangerous if you are indoors. The sealed Lead-Acid batteries in UPSes don't do this, which is why they are safe to indoor use.

Car battery can charge with as low as 2 amps. Home chargers for car batteries are 2amps/10amps.

Yep, and you'll be lucky to get 1/2 an amp out of the charging circuits of a lot of UPSes.
 
Use only jelly based car batteries, the acid will make holes in your clothing... it may be nothing, but your wife may put some ransom on you because of that.

MOST simple experiment, can't you test load with something else and put a wattmeter(tester) in between, like an clothes iron, vaccum cleaner on lower RPM's, light bulbs. Be creative mate... Just benchmark it using some math and time. Just Run a bulb and how long does it it hold. Then you will see what is actually faulty. It may be the PSU hold up time, and just the device does not enough resistance to hold up the the protection circuitry at the PSU, maybe the voltage is really low.

Some PSU's don't like Simulated Sine Wave how ever

The ones that don't are Passive PFC power supplies. Active PFC supplies should do okay on them. I would hope that just about everything in Corsair's lineup is Active.

OP has it listed as "Corsair THX 850w" which I'm assuming is a TX850, which is Active PFC.

Passive ones are relics now, but... it should not be the problem with properly made sinewave... The problem is always simple it ain't properly done.

Tested it,found mixer with 500w,UPC fully loaded but no overload.Battery is fine,i was thinking about use car batteries but that wont help me cause it would overload it anyway ;).Looks like my Pc tower itself is eating aroynd 540w.And older 480w UPC has just inadequate protection.

Yeah,dont fill this stuff after midnight...it s TX850M.

I'm not expert but i had been done some research years ago for information about UPS. UPS VA to W conversion is like 60% , 1000VA UPS is actualy 600W and iirc you want a UPS with higher watt than your power supply .Do your research since i dont remember excatly all info now but i guess you'll need around 1500VA minimum ( higher preferably if you count battery degrade , 2000VA looks better i think ) UPS for 850W power supply.

Btw a UPS guide at TPU will be nice , all the infor should not be wide spread and under shadows.

He not even pulling near the voltage i do, and i got mine 4 1/2 year ago apparently ( 2010\March ( checked were i got it from ) and the battery is just fine. How ever it is a 1500VA and i don't run the battery flat at very most 5 minutes.

It goes by what power usage not what PSU wattage you have. I tend to go with 750w psu's as my typical usage is around 200-350w which is a sweet spot for most 750w psu's with efficiency.

Been wanting to pick another up for some time now.
