which UPS will perform my needs ?

**Techie_Geek** · 20-01-2006, 07:21 PM

My configuration is

P4 3 GHz with Iltel 915GAV mb, the power requirements are ---

1.300Watt SMPS -----> contribute to 420 VA [Digit Calculation]

2.Samsung Syncmaster 763MB Magic Bright 17" ---> 115 VA

3.Canon Printer xnui255 ----> 21 VA

these are connected to my 625VA BPE UPS, but everytime there's a power failure the machine reboots .

I need a solution for this , as i want to connect two more things

1.Creative Inspire 5.1 5200 ---> 51 VA

2.ADSL Modem -----> 10 VA

Total = 420+115+21+51+10=617 VA

So should going for a 800VA or 1000VA UPS solve my problems

If I do need a new UPS , which one should I Opt for ???

Do reply fast

APC... go for it.....

**vijay_7287** · 20-01-2006, 10:57 PM

i have heard abt this prob frm quite a few frnds too
i think this is a prob in the circuit rather than lack of power

as for the new UPS , APC always

**Techie_Geek** · 20-01-2006, 11:11 PM

does taking a new UPS solve this problem or should i need a new power supply , agood one , also

**Techie_Geek** · 21-01-2006, 01:27 AM

APC Smart-UPS 750VA USB & Serial 230V has Rs 8525/-

output Connections
(6) IEC 320 C13
(2) IEC Jumpers

whereas the
APC BACK-UPS ES 650VA 230V INDIA has Rs3200/-

(1) India 2/3-pin 6A (Surge Protection)
(3) India 2/3-pin 6A (Battery Backup)

So how do I use 3pin plugs on IEC connectors ??

Please suggest and help

I have a related querry since I am also using a relatively uptodate system and a 17" CRT!

A 600 VA UPS does indeed work reasonably well but I feel it is not sufficient especially when there are power fluctuations. (Of course I know that the VA ratings are mostly up rated)

My question is whether using 2 separate UPSs for monitor and the system will be better since a 500 or 600 VA costs around Rs.2000 while one in the Range of 750-1000 costs nearly 10000.

Yes you can buy two 500VA ups also.

i use two ups's one 500va and one 700va.

500VA for cpu and 700 va for Monitor and additional cooling fans. It this does pretty good job for me.

Regards...

Thanks, but what I feel is that a modern CPU (system) consumes much more power than a 15" or 17" monitor. Or are you using a 19" or 21" ?.

**shivaranjan.b** · 22-01-2006, 03:31 PM

Sorry for the Goof Up.

it is 700va for my cpu and 500 va for my 17" Crt monitor.

My Config:
Intel Pentium 4 2.40 GHz (Northwood Core) OverClocked to 2.8GHz, On Asrock P4i65GV Mobo, 512 MB Transcend DDR 400 Mhz, 160 GB Seagate SATA HDD, 120 GB Samsung PATA HDD, GeForce FX5500 256MB GFX Card, LG GCE-8525B 52x32x52x CD Burner, Lite-On SOHW-1633S 16x48x32x48x16x DVD Burner, Creative 2.1 Inspire Series, 17" Samsung Syncmaster 793MB True Flat, Powered By 2 Microtek 600 VA UPS, 1 GB Portable Flash Drive, 10m Range Bluetooth Dongle, 4m Range Infrared Dongle, 25 in 1 memory Card Reader, Image Capturing: Sony Cybershot 5.1 megapixel DSC-F88, HCL Web Cam, Cooled By 9 fans, Running Windows XP SP2 and Windows 2003 Server (Enterprise Edition)

i get a backup time of 40 minutes to 45 minutes when the batteries are new.

Regards...

Why not use an 500VA inverter in conjuntion with a UPS . It can give u a backup of nearly 2.5 Hrs to 3 Hrs on a single battery I use the PC and TV , buth run for at least 2.6 Hrs . I know what a UPS and Inverter is , but what is the main difference betn them ???

Instead of using an Inverter in conjunction with a UPS it is better, technically and economically, to use a UPS which supports an external tubular lead acid battery. Based on the capacity of the battery in VA and the ability of the UPS to charge it, it can run for hours.

gud idea..but i have never heard of any desktop UPS wich supports external batteries. only those very very expensive cummercial ones wich have 10-50 batteries.

can u give a specific model no. and the price? wud be very helpful

thx

**shivaranjan.b** · 23-01-2006, 08:59 PM

My friend has got this ups from Numeric which has external ports for adding external batteries.

See Here for Details.....

I wrote that since I have been using a Safe Power 700 VA UPS (may not be available everywhere since it is "Made in Kerala") which has provision and terminals for external lead-acid battery. It was my second UPS and have been using it for the last 6 years. I has 2 x 12V 7AH batteries which I had to replace 1 1/2 years back. It gives reasonable backup (for my purposes) and hence I did'nt connect an external battery till now.

Dear all,

there's been a good discussion going on, can anyone give me the total consumption of my system at full load

My System is :

Intel Pentium 4 3.0 GHz (Prescott), On Intel 915GAV Mobo, 512 MB Hynix DDR 400 Mhz, 160 GB Samsung SATA HDD, LG HL-DT-ST CDRW GCE-8527B 52x32x52x CD Burner, Creative Inspire 5.1 5200, 17" Samsung Syncmaster 793MB True Flat, Canon xnui255 printer, ADSL modem

To be added soon :

XFX GeForce 6600GT 256MB PCI-E
Sony Double Dual Layer DVD±RW Writer DRU810A
VIP 400W SMPS + Additional Fans

I now have a BPE 625VA UPS, so would buying a 500VA UPS from APC fulfill all my present and future upgradation needs, or I need to go for a 700VA or 750VA UPS and discard the current one I am having

**TechGuru#1** · 24-01-2006, 05:27 AM

will 2 500-600VA "NUMERIC" UPS workup to a 1000VA UPS
I'm asking this,b'coz i have got a 19" CRT,along with 6800GS,3500+Proccy,along with a MFD.....& more so as i 'm NOT getting a 1000VA UPS directly at my place

So,wiil the 500VA+500VA = 1000VA formula work out?

You mau use them separately for the monitor and the system but I feel that in your case (3500+6800 GS etc.) higher capacity UPS is needed for the system. See, VA x Power Factor will give the Wattage and supposing PF is 0.6, the actual power of a 500 VA UPS is only 360 Watts.

From the earlier discussions, I feel you better buy a new 500 VA UPS of a reputed make like APC (few other good brands are also there) which may be connected to your Monitor only and connect all others to your existing UPS. I suggest this for one more reason which was not mentioned earlier. The initial starting current requirement (Surge Current) of the monitor is many times more than its normal current consumption.

This way you should get much better back up also.

**Techie_Geek** · 27-01-2006, 01:48 PM

went to the market and this is wat i got :

Microtek 800VA double battery Rs 2200

APC 500VA Rs 1800

APC 650VA Rs 2650

keeping in mind the upgrades in the near future which I should go for ???

The initial suge current is not a problem, cause it's fed by mains, problem is that when current off occurs and CPU is idle it gives smooth backup, whereas when CPU is loaded say any Games or Photoshop etc going on, it just reboots the machine. And then provides 10mins of backup

Now that I want to keep the older UPS which of the above three should I go for ??

Do I need to change my SMPS during the graphics card upgradation ?

I presently have 3 fans, should I need more fans too ?

[quote="is that when current off occurs and CPU is idle it gives smooth backup, whereas when CPU is loaded say any Games or Photoshop etc going on, it just reboots the machine. And then provides 10mins of backup

[/quote]

Does'nt this indicate problem with SMPS? This is only a logical doubt and experts pl clarify.

**naveenchandran** · 27-01-2006, 09:28 PM

Always make sure you buy a 650 VA UPS. New computers need >500 VA for the Built in battery model.

**janitha** · 28-01-2006, 07:05 PM

Quality of Microtek I don't know, but being one with two batteries, it should give much more back up, though may not be double.

BTW, why should you use such huge fonts?

I posted it earlier and no one responded, so to make everyone see my question, the fonts are large

**Chyawanprash** · 30-01-2006, 11:26 PM

dont bothr upgradin your ups. just overclock it and upgade its firmware. i overclocked my microtek 600va to 800va with default cooling. it gives me 1hr backup on my microtek 17'' monitor.

I am not able to comment on this, but would very much like to hear comments from others!
