Exclamation Power Surge on Computer, Power Supply Makes funny noise, PC doesn't turn on

I have an intel pc, I don't think the specifics are not that important so I will not divulge into them. This is more of a power supply question since I have narrowed it down to this problem area.

The electricity went out while the computer was running, now I turn it on and the power supply makes this little noises like its trying to turn on but can't, its like revving up your engine but it just won't start.. This type of sound except on a smaller scale than a car. That's pretty much it it makes these noises while i try to power it on and the computer never boots up.

The power supply information is as follows verbatim from the power supply box:
SPI - Sparkle Power Int'l LTD
Switch Power Supply
Model No. FSP200-50SNV
AC Input: 115/230V~, 613A, 60/50Hz
Max Output Power: 200W

The plate that encapsulates the power supply says to NOT remove this cover and try to service the inside of the power supply, it says that the inside yields not servicable parts. I doubt this. All I really want to do is fix my power supply, how would you recommend I fix my current one, or how can I identify for sure that the problem is from my power supply if I want to replace it with the same model that they sell online for about $40?

Be as technical as you want in your response, Thanks for reading.

Well a PSU is what it is, And actually does not have anything serviceable. It is just full of transistors, capacitors etc (Which are like very hard to find replacements for, since you need specifics).

What happens when you try to turn the PC on? Does it actually come on or anything?

Thanks for the reply.
Nothing happens on the monitor, there is just a repetitive noise coming from the power supply box, that's it. The PC never boots up, I've taken out the HDD from the pc and put it in another PC and I can access the files, so the HDD appears to be fine.

If all I can do is replace the power supply box, is there a cheaper alternative box I can get that should work fine to replace my current one? I gave you my information on the power supply box in the above post.

Checkout newegg if you are after just a cheap replacement. Just a 200W whatever if you can find one.

Usually I would be recommending a decent brand PSU, Because cheap ones never last. But since it sounds like an old PC, I don't think it would matter.

I found these two sparkle power supply units at newegg:

Both are 250 watt, will that be okay as a replacement?


Here are some more stats/info on my current power supply:
