PSU went KABOOM! (I think) ???

Had a 550W, just did the calc on coolermaster's website. Apparently I need a 435W minimum. So anything 450+W.

Price, we are basically giving it as a gift, so not too much. I will prefer as low as possible, but I know I have to get something decent.

Rather splurge out an extra R100 - R200 and get 600W+. At some point you're going to upgrade your PC and require a much bigger PSU. It's better to pay a little extra now than buy a brand now one again a year or two down the line.
 
Those cheapy UPSes surely cannot be line interactive...
Actually they are. Current goes straight through it & they one kick in (interact) with the mains power if needed. They aren't the ones you really want though. Double conversion is best, but also well out of most people's price range. :/
 
I think surge protection is going to be the cheapest and easiest here. A smallish 600VA UPS can cost around R800, and that may cause more damage than it is worth in it's benefits.

We got quoted on a 3.5kVA double conversion line interactive UPS, was around R11k a while back IIRC...
