Power for Speaker

Picked up an old CRT Screen with a pair of speakers for a old desktop that is a spare machine at home. The power plug is similar (maybe the same) as the power supply connection that goes to my laptop. But there seems to be no connection in the back of the old desktop.

Speaker make is Diamond.

Any ideas on how to get power to the speakers?

Check the back of the speakers and they should say what voltage it requires, if it is 220 volts or around that mark try just plugging them into teh mains ?

Sounds like the screen was off an old HP or similar PC and some models had a separate filterd 12v power output socket in the PSU that you plugged the speaker power cable into.

Because you have a socket not a plug, you can't just use a separate power supply brick (ones that are in effect a power plug & transformer) because they also have a socket, not a plug as you require.

Even if you could wire it from an internal mylar plug (used to power hard disks), the noise would make the speakers useless as it is not a proper filtered supply which is what you need.

I would forget about the speakers and buy/use something else.
