Curious SSD behaviour.

I have an February 2014 Intel SSD (SSDSC2BW120A401) that one day
refused to work anymore when plugged into the motherboard Sata socket.
In fact it would hang the computer.

I bought one of these......

connected to a PCEe card USB3.......

for archiving other stuff, but I thought I'd try the busted SSD in it,
and it works?
Why?

Using bad sata cable? Bad sata socket on mobo. Bad sata power cable from
power supply. Or poor seating of any of the preceding.

"when plugged into the motherboard Sata socket"

What kind of power source was it using at the time ?

Sandforce drives can have slightly high power usage
during writes. As Sandforce controllers do data compression
to make the best usage of Flash memory bandwidth. A lot
of Kingston brand SSDs have used Sandforce chips.

I would think carefully about the motherboard power path,
and whether it comes through a Polyfuse protected path.
And the protective fuse was opening, soon after operations
started. Normally, there is no significant choke point
in desktop ATX PSUs, to cause a problem like that.

Check the power pins on the 15-pin SATA feeding that
drive inside the PC, and make sure nothing was damaged
on the connector.

That's the only reason I can think of, for a different
hardware connection making it work. Somehow, the
power it needed, was available.

You can verify the SATA data port inside the PC is good,
by testing with some other SATA storage device (HDD).

SSD datasheets are not a trustworthy source of info
concerning device power. Same goes for "what is printed
on the tin". Some Sandforce have peak power usage
of around 7W. There is at least one SSD review site,
that measures power consumption while benching them,
to give more realistic numbers.

I have two SSDs here, and I measured the power while
benching them, to make sure they were safe to use
with my USB adapters.

When it comes to data preservation I am somewhat of a paranoid. You stated
that the SSD is from Feb 2014. Is that the creation date, or the date you
started using it. How heavily used it the SSD? Have you checked the SMART
data to see if there are any indicators of problems with the SSD or that it
may be reaching its end of life as far as terabytes written? I had my first
SSD refuse to mount, then after another reboot just disappeared. It was
within its warranty period, but the manufacturer had terminated warranty
support two months earlier. Needless to say, I was upset. Now I use the
manufacturer's supplied app to check status every month or two (different
manufacturer of course - never buying from the first one again). And since
it is my system drive I am much more religious about doing my backups.

Anyway its working fine, and has passed the HDD tests.
