UPS recommendations
-
Ive used an ultra UPS from tigerdirect.com for a few years without any issues. It came with a 3 yr product warranty and a $125,000 connected equipment warranty. It also has some software and a usb connection for monitoring the psu, or for the psu to react to an incident. This is the newer version of what I use for right around $100 http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=770423&CatId=20[^] you can poke around that site and find a few higher end models as well though

I decided to grab an APC. Thanks for the response, though!

I've had a couple of APC Back UPS ES 500's running for a few years now with nary a problem, except when I plugged too much into them. It didn't return any errors or beep at me but it tripped and reset itself. I thought it was a power supply fault until I looked at meter in APC's PowerChute software. Oops. Got a bigger one to replace it. Had a lightning strike on the power pole just outside the window (7 metres / 20 feet) & everything survived, except for the laptop's video card (NVidia Quadro - thank Gawd for on-site warranties) but I think that was more to do with the EMP (Electro Magnetic Pulse) than any power surge cos the laptop is behind both the UPS surge-protection and its own AC-DC converter. I had to reset/reboot (EMP again, I think) everything but it all came back ok. Yes, it was loud.

Thanks - I did end up going with an APC. - Jon

Skip PCM Powercom brand units. Had a pair of 'em, both went flaky and would start beeping, switch to battery when line voltage OK. Tried contacting company about repair / replacement / upgrade; messages never acknowledged. Big APC 750 of same vintage still in service. James

A power strip is OK -- provided it is NOT also a surge suppressor (which most power strips are). Most UPSs generate sawtooth wave rather the expected sine wave. A SP would consider that lots & lots of tiny surges, and it would be constantly "suppressing" them. This could lead it to overhead (and catch fire).

I've never heard of a sawtooth wave UPS. Most consumer/entry level commercial units use a modified square wave. http://www.pcguide.com/ref/power/ext/ups/funcOutput-c.html[^]
Otherwise [Microsoft is] toast in the long term no matter how much money they've got. They would be already if the Linux community didn't have it's head so firmly up it's own command line buffer that it looks like taking 15 years to find the desktop. -- Matthew Faithfull

"Sawtooth" is probably the wrong word. "Stairstep" is probably closer to what I was thinking. (if you look at this page, http://www.dspguide.com/ch3/1.htm[^] -- scroll down about half way to the graph label "b. Sampled Analog Signal" -- and yes, I know that's about audio signal, but waves are waves for this discussion -- that roughly should what he was talking about) But, regardless of what the waveform actually looks like, the advise about surge suppressors on UPSs was told to me by an engineer at ups-maker APC, who show know what he was talking about.

Well there is a feature in BIOS, "Restore on AC power loss", with typical settings of power on, power off and last state. This would be able to turn the pc back on when power is restored to the computer (meaning the UPS went got fully discharged). Would be nice if the UPSes would soft OFF and soft ON for the PC though...

If you buy an APC (I recommend) look for the software & cable. Almost all APC units support a connection (via USB, these days) to the protected system, and software that will allow your system to monitor the UPS status and auto-shutdown when the battery drops below a certain threshold. Some units support the functionality, but won't come bundled with the software/cable. (You can order it from APC directly if you get one of those.) Many units have it in the package. If you get one of the larger server-level or rack-mountable units, it may have networkable software packaged with it. One server actually connects to and monitors the UPS, but the software would be able to auto-shutdown an array of systems instead of just the one.

when I looked at this a few months ago the only difference between it and buying new nonsale models at a boxmart was the free disposal of your old one. Waiting for a good sale would be significantly cheaper.

True. the cost savings is not huge. Here is a listing for a 620VA that is probably comparable to the 650 that was qoute at the begining of this subject. less that $200 is not bad, but not the deal of the year either. some things just require balanced compensation for their benefit.

I paid significantly less than that for a 1300VA model. IIRC the nonsale retail price for the 1300s is around that.

Or be trying to sell you a bigger UPS. :)
