Forgetting the potentially harmful spikes, I've heard the voltage often dips very low for quite long periods of time - and that not all power supplies handle these low values well.
Hmmmm ... $99 +GST from
PBTech or similar.
Luckily, my main work PC is a (permanently plugged in) laptop, so I'm covered with that one.
It's true that the power brick on laptops offer a degree of protection, but if it were me, I'd have that plugged into a UPS as well. The important things to note about UPSes are as follows:
1) Must be line-interactive. Any other form is pointless. Even the LI models aren't TRUE line interactive, but none of us is probably in a position to have the cash free for REAL LI. Since power aberrations occur quickly (in milliseconds), the UPS must be able to compensate as quickly. The power is supposed to pass thru the regulator, to the battery, to the outlets, but I've been told that non LI models don't do it this way and so a good number of the nasties make it thru
2) Voltage. Since a 650VA is really only rated as a 350-400W max power draw, one needs to be very careful that one has a UPS that matches the power draw. A laptop is no prob as even the "big beasts" max out at 150W. But a good simming rig should be busting 400W easily. Like with speakers, I say have a good amount of "head room" so that when those spikes of power occur, the poor old UPS doesn't get maxed out (and the risk of sudden shutdown with it)
3) Brand. Not all UPSes are created equal. I've sold Dynamix, APC, Eaton (Powerware), Blazer and a few others. As with all things, the QTP equation comes into play. At a pinch the Dynamix ones are ok, but I wouldn't seriously consider them for a simming rig. My pick of a great mix of price vs quality is the Eaton Powerware range. Of course if money is no object (suddenly deafened by the howls of laughter and guffawing...) the APC or Liebert are the picks.
Two things I always try to avoid skimping on: a good quality PSU, and a reliable UPS. The number of PCs and laptops I see each year that have been damaged due to cheap PSUs and no UPS I've lost count of...
