^^ no re, Back ups have problem with Antec Neo HE. Me, x86 and even chaos had the problem when he used backups, but he changed to Smart ups. It has problem with few other smps as well iirc.

Antec is supposed to be one of the decent PSU's around, i'm surprised to hear it can't deal with a APC-backUPS ...and the cheaper models (mine's a mercury) has absolutely no probs with it at all.

PSUs in general dont care about sine wave delivery, very forgiving. What about the cheaper indian UPS's, they sure as hell don't deliver a sine wave :hap5:

The point i'm being trying to make, (which seems to be lost) is that you dont want to go in for the lower duration units, think about how long it takes to burn a dvd, if the current goes when that happens and the UPS cant provide enough, you just lost the DVD. Double or triple the time it takes and you will be fine.

Also think about deep discharges, the APC battery can handle 120 of those and then you have to replace the battery, get a shorter duration UPS and your battery is dead in a yr or little more. Deep discharge is when you wear the battery out completely, better to avoid, if you want the battery to live longer.

Short duration 5-15mins ups are fine in countries where the power goes off for a few minutes, that too rarely. Maybe they are also fine in Mumbai, if you live anywhere else they are a waste. I used to get half hr cuts at random and i was fine with teh RS-1000, its those random cuts that were the most annoying, i did not want to stop what i was doing, so the 1hr or so i get was ample enough to ride through them. If there is a scheduled cut, then i can plan around it and shut down within 5 minutes.
 
Well, I don't mind stopping what I'm doing, as long as I can cotinue after the power comes back. The smartUPS is the only one which can do that.

I'll be buying locally. Prices are 300-400 more than lammy, but I'm not interested in lugging a 15kg box thru the train :no:

Only if you are *not* physically there, is this why you need it to come back by itself ?..its a remote machine and you want it to recover after a power cut.

I don't see any other option than to go for the smart ups in that case.

Local brands will work out cheaper, if you can get one that allows you to connect via USB or other and configure options like don't sound the alarm while i'm asleep, ie be able to configure them to a certian extent.

There is nothing special about an APC back-ups otherwise.

Yes, that's the only reason. The power cuts usually occur during the daytime, when I'll be out.

I believe most higher capacity models have USB connectivity and allow configuration thru software.

Now I'm thinking something like a powersafe 1kva would be better than a smartups 750 :P If the PC doesn't have to shutdown, then the question of auto startup doesn't arise :hap2:

this is dependent on how often you have cuts in the *same* day. having one as i type this :(

It takes upwards of 8 hrs to charge mine, for just 1 hr with everything running.

The cuts i hate the most are a few hours in the morning followed by another few hrs later on. The battery is trying to recover and it just got killed again. Thankfully this happens rarely.

I don't follow what u mean by not having to shutdown ?..is this like an AT style switch that you have to physically throw yourself.

Then yeah, you can set the machine to go into hibernate mode when the battery is nearly dead, power returns, it starts up on its own. The only downside here is while the power was off, you pc hibernated and is still drawing juice, so if there is another powercut, then you will down very soon after.

I am sure you did not notice it but in the OTHER room the computer was attached to a PCM (Powercom) 1kva UPS. This works perfectly and it has an option to attach additional external batteries for longer backup times. I paid about 4 k for this UPS in July 06. Only hassle with this UPS is the serial port connectivity :(
 
^Yeah I got the same one around 4.2k recently for a friend locally as apc 800 wasn't avilable ... prob is the jetway hasn't got a serial port, though you can connect one through the header on the mobo and in my frinds case i tried 3 different com ports but it didn't work so check it before you get a serial one

I got mine working ... but it is necessary to get the 6 inch serial cable from MoBo serial header to backplane from the MoBo itself as this cable's pin configuration is the most non-standard standard you will ever find... MoBo's have a different layout on the header as to which pin carries which signal - this info is normally given in the manuals...... it is a real P.I.T.A of the MoBo does not come with its own serial backplane cable.

The PCM UPS software is really bad - visually crude and hardly any info and it shows shut down option as "shut after xxx seconds of use" and not like the APC which says "shut when xxx minutes of power remaining". Attached screen capture...

 
ok 1 thing.

The VA rating alone is not indicative of how good UPS really is.

The thing is I have seen 800VA microtek failing to give backup on a C2Q machine for even 1 sec. As soon as i cut the power machine just shut down immediately. UPS was not able to tolerate the pure wattage requirement of that system.

I know it C2Q but the machine was running on GF7100 and 1 hdd thats it.

Where as APC SUA750I APC RS800VAdid not have any issue.

Does Microtek or Powersafe give out any info regarding how much load the UPS can actually take? Atleast APC does tell you how much load it can take.
 
i got the microteck 600va ups , its running fine on the c2d e4300 + 160gb hdd + 8500gt . giving me backup of a good 5 - 6 mins, i have never tried staying on ups any longer than that.

though with the quads it might be a different story altogether.

That could be a problem :( Is there any serial to usb cable??
 
I'll get the prices for various models from my dealer in half an hour. Till then, let us ponder on what capacity would be required. Check my config in my sig, and tell me what would be required for a backup for over 2hrs. (Speakers will not be switched off, and even monitor will be off if I'm only downloading :P)

I dont think the software will work if attached to USB port it probably will not be capable of getting readings from USB port. RIGHT ?

If you want long back up time - 2 hours - you will have to look at UPS's like the PCM 1kva which has the option for external batteries - with external batteries I suppose backup time will be as long as the amount of battery power you have attached. :) I dont know if the APC 1 and 1.5kva BackUPS have this option... ask CHIEF he has a 1.5kva APC !!

Zhops please do confirm the price of the UPS you decide on with Nilesh of APEX. So far his prices have been good for UPS's. Use his price to bully your supplier into reducing prices.
 
so this might be problem with my system.
my system gets off less then 10 seconds. i have local crappy ipol UPS-500W
what should i get. kind a low on budget...

back-ups RS-1000 indeed does have this option, so does the 1500.

The APC 650VA would give you around 10-15min backup max and can handle upto 350watts iirc ... though I'd recommend atleast the APC 800VA or equivalent from any other brand
