When you "let the magic smoke out", it's almost certainly dead. Can't see it not being
toast, but stranger things have happened. Your motherboard may be going to the
same place, how does the socket look for the melted 4 pin?
What's the make and model of your deceased psu?
The cheapies are somewhat lacking in protections, and a dying psu can and will send
voltage spikes, quality psu's have better overvoltage protection, making them more
likely to just shut down, not hosing other components.
Unfortunately, aside from a visual inspection, you won't know about the rest of the
system until you try it. You can test parts in another pc, or borrow a psu from
someone who has a spare. Make sure it's a spare, just in case. Also it needs to be
half decent and sufficiently powered for the system, testing with a substandard psu
inadequate wattage and amperage, would not be a good thing.
