Hey, I'm after a good PSU, 30A or more, but I don't have much money....

Is this a good one? Does anyone know if they are reliable?

It was the Palstar PS30M, they were a good PSU, we used to sell them. I am not sure if I personally would buy a PSU off of there, as you don't know how it has been used in the past...

If you wanted a new one without breaking the bank the PSW30 is a good choice.... http://www.thunderpole.co.uk/power-supp ... sw-30.html

The PSW30 is switch mode, the PS30M was solid state.

Would you please mind explaining what the difference is?

Can they both do the same things?

Here is what I think you're asking:
A conventional power supply would be one with a transformer, rectification and smoothing, followed by transistorised regulation. It may produce a little ripple on its supply rails. It is the traditional, large and fairly heavy PSU.
By contrast, a SMPS doesn't use a large transformer, but instead a switching regulator. Some can produce a lot of noise on their outputs and may emit substantial RFI. They are generally physically smaller than the traditional PSU's
This is why some people have had reception issues when they are near computer laptop power supplies for example.
I'm sure another member of the forum can offer a more concise answer, but I suspect that this is what you were asking.

Hey thanks dude...

Yeah pretty much... My laptop chargers send my Radio's loopy when they're on...
I hope my new PSU doesn't!
