Do I really need a UPS?
-
My APC UPS just went offline, taking the computer down with it, making a horrible screeching noise of an alarm. I unplugged everything from it, unplugged it from the wall, and power-cycled it.
Looking at the error code F02, it says it's an "on-battery output short" and the manual recommends doing what I did.
But...I've also read that this is a recurring problem with APC units, and considering that mine is more than a few years old, I'm wondering if I really need this.
There's really nothing mission-critical that I need a power supply for a few minutes so I can safely shut everything down. Everything is backed up (to at least 3 places, including the cloud).
Would a nice big power strip do the job for me? It would be a lot cheaper than replacing the UPS.

We lost two motherboards on two separate PC's, most likely during thunderstorms, and the tech recommended getting a UPS. We haven't had any problems since.

A power outage during a critical system write can play havoc on your system.
Risk vs. Reward. Your call.
Yeah, I know. The worst thing that can happen is that it crashes the hard drive and makes it unbootable, right?
I can restore it in about 3 hours. I get it that professionals can't afford that kind of downtime. I can.

When I say 'lost motherboard', the PC was completely unusable. The HDD wasn't damaged, but it fried something on the main board.

Wouldn't a surge protector accomplish the same thing?

You don't necessarily need a UPS, but wouldn't be a bad idea to at least have a surge protector. Another step up is a voltage regulator and something that smooths out "noisy" power sources. Surge protection aside, I am not familiar with consumer electronics that offer those two other functions independently, but good UPS units typically have all those built in.
I have a setup where I have a laser printer hooked up to the same circuit as a desktop/server computer along with a UPS. Every time I "wake" the laser printer up, it draws enough power that it would trigger the UPS. In that case, the UPS protects my desktop/server from the transient power irregularities caused by the laser printer waking up, and avoid a needless restart for the desktop/server machine. (And yes, @mark , I use CyberPower units for the more important stuff; though I still have older/smaller APC units in service as well.)

You need power conditioning and very good ($$$) power conditioning to prevent that. Lightning is very hard to stop and very expensive. Most good UPS have better power conditioning than a typical "surge protector". A surge usually occurs when something in the power chain unexpectedly puts excessive load on the power supply.

We had surge protectors on both PC's, based on that theory. I wasn't convinced they'd done what they were supposed to do. It's possible it wasn't a surge, but I figure for the sake of $100, what the heck.
However beautiful the strategy, you should occasionally look at the results
(We use Cyberpower UPS's)

Buy a Mac, bitch.

That's like telling somebody who was raped by a priest to join the scientologists.
