No, more like the SATA drive is shorted. The drive mechanism may be intact but the control circuits are toasted. A like drive with the same control card aboard would effect a repair and recover the data on the drive. Power outages can severely damage semiconductors, no rhyme or reason for what fails but they do not like having power interrupted.

This link may tell you more about SATA connectors than you ever wanted to know, if it doesn't open at SATA power cables either select that from the menu or scroll down -
The only difference I can see between old and new cables is that for full implementation they should have the ORANGE cable which carries a +3.3V rail. I have to say I agree with Platypus' advice that any cable which has smoked should be binned and a new replacement fitted.
If I understand you correctly, it is the SATA power leads which are causing your problems. If you are using a cable which has never to date 'smoked' then the problem has to be at one end or other. Either the PSU you are using is faulty or the device you have the power lead plugged into has developed a short circuit. The best thing to do probably is to test the voltages on the device end of one of your SATA power leads. You will need a multi-meter with a fairly fine probe to do this. You say your computer will start running without any hard drives connected, that is when to test the voltages which you can get from my link.
PSUs are fairly clever devices, if they detect an overload on any of their outputs they will normally shut down completely, to prevent any further damage so the first thing to do is to check these output voltages. I fear that this power surge has done a lot of damage to your computer, it may be time to talk to your house insurers if this took place at home.

Are the Sata Power cables different from one Psu to another? Like delivers different voltage? Because i am using the old ones that were in the Psu that blewed up
It's possible they could be different. Always use cables provided with the PSU by the manufacturer.
I've just noticed you said the SATA port smoked when you connected while the PSU was powered up. If the PSUs use a different wiring sequence on their SATA power outputs, the SATA controller may have been damaged.

Sounds like besides the drive taking a hit, the MOBO sounds like it has seen an overvoltage and some stages aren't working properly. I love the smell of toasted circuits in the morning, like the smell of popcorn at the big screen.

I hate being a pessimist but I think your solution is not to 'stay on IDE' but to get a new mobo. The problem here appears to be that when the power went out it created a voltage surge which is what damaged your computer.
It is not just switching power on that creates a voltage surge, which it does, but switching power off also creates one. And the more violent and sudden the switch-off, the greater the surge. And if the surge gets through the filters in the power supply there is virtually no protection on mobos, and semi-conductors really don't like over voltage.
