Power Tower PSU question

[Ianoakley]

There should be no problem with replacing like for like however AT power supplies are not that common.
Best way forward is to buy an ATX power supply and fit and ATX to AT convertor as supplied by Amigakit (product code ADAPV003).You will also need an ATX power switch (PWRATTXSW1) which can be fitted behind your existing Power Tower on off switch.

There are two advantages with this way forward:
 1. it future proofs your power supply and
 2. you can get a power supply with a beefier output

The Power Computing AT Amiga cable - is that the lead that plugs into your Amiga and then you connect the P8 & P9 connectors to the power supply.
If that is what you refer to that item remains however the plugs are connected to the convertor instead of the AT power supply.
If you get a Mediator 1200LT you ditch the Power Tower lead as the P8/P9 attach to that unit.
Works a treat!!.

I assume the ATX convertor is similar,if not the same, as that sold by Amigakit whereby the ATX lead from the power supply plugs onto the converter and the P8/P9 plugs from the Amiga complete the circuit. If the power switch is attached to the converter it should work - that was my set up before I purchased a mediator.
Might be worth testing with another power supply.

What a pity Power Computing's standards regarding the Amiga have stooped so low. I've ordered lots of stuff from them and have had no complaints regarding the service. Mind you my last order was a few years ago. However compared to Amigakit there is no comparison and their service is excellent.

Hope you get this sorted !!

Bet you wished you'd stuck with your AT supply however I presume everything worked with that !!

With the floppy / front led solution does the Amiga boot?
Also when you try the HDD and CDROM is that with the floppy also connected. Try each component individually and see what happens. Make sure the AT P8/P9 connectors are the right way round. Also try without the blizzard.
The easiest test is the ATX power supply if you've got a PC.
I've spent many hours fault diagnosing and whilst it's a pain it's the only way to get to the root of the problem.
