PSU variable SATA power?

Hi there, bit of a noob round these parts so my apologies if this question's in the wrong place. I've googled it and am still unsure.

Basically i'm putting a PC together and wanted to format a hard drive to use as the system drive... unfortunately I shoved it in a knock-off enclosure which I had another drive in, without looking at its power rating and ended up with a possibly fried PCB (there was definitely some smoke :eek:)

So can I get something straight that has been preying on my mind since I possibly fried that hard drive PCB... I can see that the two hard drives I have, have different power ratings which is why it went wrong... but the question I have is: do the SATA power cables from my PSU all have the same power rating, and as a result will I only be able to safely put in components with that power rating? Am I risking frying my stuff by just putting it in willy nilly? I can't see any specific ratings immediately available on the PSU itself (although I haven't bothered taking it out of the case), and I don't have the manual as it's just an old case I had knocking about.

Any help would me much appreciated :)
 
There aren't any ratings you need to worry about. No hard drives will draw anywhere near the maximum capacity of a SATA power connector. The reason that enclosure fried was because it was crappy.
 
sorry, I wasn't clear - I meant that the hard drive PCB was fried...the sata connector from the enclosure fried it - despite the fact I'd used another hard drive fine with it. My reasoning is that my other hard drive, which has a higher rating, was fine but that amount of power was too much for the second. Does that make sense? And should the enclosure have recognised the lower power rating on the second hard drive and lowered it accordingly (and will my PSU do this automatically?)

thanks for the help!

Once again, it was because the enclosure is crappy. It should only supplying as much power as the hard drive is asking for. Either that, or your hard drive was crappy.
