Well, what was the old PSU, what is the new PSU and what did you install in your rebuilt PC?
A well-designed PSU should be able to gracefully handle most typical faults so if yours exploded, it was either of sub-par quality or had a spectacular malfunction. In most cases, protection circuitry in the PSU and on the motherboard will prevent most damage and the PC will work fine once you put a known-good PSU with adequate rating in.

When building a computer never skimp on the PSU. The first one wasn't a good one and the new one is just as bad if not worse than the first. Have you tested the rest of the system yet? It's very possible other parts may have been damaged when the PSU blew up. If you managed to get lucky and the parts are undamaged do you really want to take the gamble again with another junk power supply.

What are the system specs? You might be able to test with that okia PSU to see if the system will work, but I wouldn't suggest using it as a long term solution. That Okia PSU is only rated for 18a on the+12v making it closer to a 250w PSU than a 450w PSU. It's possible the old PSU blew because it couldn't handle the load of the new system and if that is true the Okia will probably also die in a spectacular fashion.

What is in the computer that you were trying to have that unit power? It is possible you overdrew the little old PSU, the okia likely won't do much better, not if you have any graphics card worth noting in the system.
Also that Thermaltake PSU seems to be old enough to have a red voltage switch on it, was it set to the right level? If you are in 120 and set it to 240V it won't work but it generally won't explode, if you are in 240 and set it to 120 it will double the voltage and feed 480 into the main circuit and blow the crap out of the primary side.
