Greetings, good readers. I feel like doing something different today. Going left when I should be going right. Going west when I should be going east. Going to the busiest intersection in town and screaming out loud for no reason when I should be going to the sanitarium. Wait... that's what I do every day, isn't it?

You know, I don't think I'll do any of those things today and review something new instead, the PC Power & Cooling Pro-Source 1500 UPS.

That's right, folks, I'm taking my first trip into the lands of the Uninterruptible Power Supply today. And like many UPSs, this one has many features printed on its plain brown box. And it even came by UPS too.

  • Pure Sine Wave, Line-Interactive UPS
    -these are both good things to have, especially for a modern rig with an APFC PSU. The pure sine wave thing indicates that the unit is designed to get closer to a pure AC waveform than some cheaper units out there can do, and this will be less stressful on attached components. Wall warts in particular will find this unit easier to tolerate. And line interactive is good too, because it doesn't just sit there when not in battery backup mode. It operates as a line conditioner as well, helping to filter incoming power as well as trying to maintain a stable output voltage for anything plugged into it.
  • Micro-processor Based Design
    -as opposed to an electromechanical design maybe? Of course it's got a microprocessor - it couldn't do what it does without one.
  • Smartest Charging, Fast & Stable
    -this also applies to horses. If you get in their stable and act smart with them, they'll charge at you fast.
  • Self-Diagnostics
  • Buck & Boost Line Conditioner
    -that's that ability to maintain a stable output voltage I was telling you about. Too high input voltage, it bucks. Too low, it boosts. Much like those horses you were acting smart with earlier.
  • Replacement / Low Battery Indicator
  • Battery / Load Level Indicator
  • "Green Power" Design for Longer Battery Life
    -whatever that's supposed to mean. Is Al Gore on the board at PC P&C?

This particular UPS is a 1500VA model. This makes it good for about 900 watts of load at the outlets. Take care here folks - that doesn't mean you can use a 900W power supply and max it out. It means that any power supply you do use can't exceed 900W at the UPS. Typically, that means you can maybe max out a 750W unit rated at 80 Plus Bronze on this unit, and only if that's the only device being powered by the unit.

A mere three year warranty, PC P&C? I've come to expect better support than that from you.

Since the box for this unit is as dull as a bag of dirt, I'm not going to waste time by taking too many pictures of it. It's time to unpack.

Ah, there we go. We get one UPS, an owner's guide, a CD with the control software on it, a little bag with a funny red connector and wire in it, a USB cable, an Ethernet cable, and a green RS232 cable.

It's not a half bad looking UPS, is it? That's an 80mm fan you see on the side there.

Here's a better look of the fan area, along with the glossy black paint that finishes the Pro-Source.

Hihowareya. This is the other side of the unit. No more fans, but lots of grille area. Looks like the fan is mostly there to cool the bottom section of the unit where the main transformer is. I'll get in there and look at it in more detail on page four.

Here's the back panel for you. Six outlets is more than enough for a 900W unit, because it's always a good idea to only put the stuff you need on a UPS. Computer - yes. Monitor - yes. Speakers - maybe, especially if you own the ones I do. "Hello Kitty" desk lamp... you should think about just plugging that into the wall instead.

This is a closeup of the RS232 interface. The manual actually says to go over to PC P&C's website to get detailed instructions for interfacing to this port, but to be honest I couldn't find said instructions over there.

Over on the right side of the picture you can see the USB interface as well as a yellow sticker that appears to suggest that someone at PC P&C did in fact get smart with some horses, and they did charge at him, but he's ok. I'm glad to see that... I would have worried about that for a good thirty seconds.

Here's the manual, and a useful one it is. I can't think of anything about a UPS that this manual doesn't have, actually. The whole back section is one big specifications chart. You say you want to see all these specs? Ok then, here they are:

*mine didn't have this optional cord
**they're so pleased about this, I guess we needed to hear it twice
***do not use in the shower
****I guess if you live on Mount Everest, you're outta luck

Now that I've worn my fingers down to painful stumps on that huge spec table, I'll let you gaze on the included software CD for a moment.

The included USB cable is 68 inches long, for those of you who care about such things.

68.5 inches for the category 5E ethernet cable.

68.5 inches here too. One connector has a little label on it that tells you it's the UPS end.

Before I get to testing this unit, it has to be made ready. The first thing to do is hinted at by this little white sticker. REMOVE.

And so, remove I did - the metal piece under the sticker that is. There are two screws holding it on.

With the little cover off, we get to see a little connector back in there. That's where you plug in that weird little red connector with the thick wire. What it does is, it connects the batteries to the rest of the unit so you can use it.
