Replacement power supply.....

THX1138 · 15 May 2005, 10:39

I have a Micronik 1200 Mini Tower and i was wondering if i could replace
the power supply with another one ?

Do i need to be looking for anything in particular or will any pc power
supply do ?

Verify that the power cables are similar to this:

or this:

Well,it doesn,t really look like either of them,becasue rather than going to say 1 or 2 connectors that would connect to a motherboard,this one connects directly to the on\off button on my tower.

I don't get it.. Can you post pictures of the old PSU and where all the wires coming out of it go?

THX1138 · 30 May 2005, 10:52

Well it won't be easy to see as the power supply is mounted in the
tower.

This is the power supply that i want to replace !

Hmm ok..

It's probably an AT power supply judging by the fact that you mentioned that there was a cable going to the tower's power switch?

If you look at the cables that connect to your busboard or motherboard, you should see connectors similar to the first URL I posted.

If not, you'll need to modify the AT power supply.

An ATX supply will not have the correct connectors, but one of those can also be modified to work.

99% this is a standard AT power supply.... just order one from a good computer shop... they still have them (at least here) but they cost more...

Ah.......ok,didn't see the one going to the busboard !

As well as the black cable going to the power switch of the tower,there is also an 8 pin connecter going to the busboard !

So,what do i need then,and AT power supply ?

When I asked for pictures, I was mainly looking for pictures of the connectors going to the mobo/busboard. :-)

Sorry about that

Here is a couple of pictures of the power lead from the psu and the connector
which it connects to on the busboard.

Look at the first URL I posted.. Are the colours the same as in connector P8? Judging from the picture, they might be, but you can turn the connector in your hand and verify.

THX1138 · 06 June 2005, 21:16

Well for starters P8 is a 6 pin connector and mine is a 8 pin !

And my colours are.......black,black,black,red,red,white yellow,blue

Jope · 09 June 2005, 07:05

Ok, then you need to select the correct voltages from the AT power supply and plug them into your existing plug.

THX1138 · 09 June 2005, 19:54

Thank for the information Jope............Not as straight forward as i thought it was gonna be !

Jope · 10 June 2005, 06:03

Yeah.. Pesky Amiga tower manufacturers, some really had the obsession to make things proprietary. I mean the P8 and P9 connectors all had all the voltages they needed, I bet it'd have been cheaper to make them take unmodified AT power supplies instead of these own non-standard jobs.

Thankfully my RBM tower uses a stock standard ATX PSU with an adapter cable in between.. Lucky on my behalf - I didn't really even think about this issue when selecting the tower.

Then again, back when I bought it, you could either buy the RBM or .. well yeah that was the only one available in .fi in 1999. :-)
