the main difference between an AT and ATX PSU is that the ATX PSU is always live, and is turned on and off via "software", wheres an AT PSU is turn on and off with a proper switch. Thats why on modern PC's you can switch them off from the shut down option, because the PSU is connected to the motherboard, so it can send the off signal to the PSU.

Hi CU_AMIGA,

To make the ATX PSU switch on, connect the green PS-ON wire to ground (black wire).

Being an ever helpful person, I have a guide on this subject:
Amiga PSU guide

Scroll down a bit for a picture of my cable.

Can't find any AT PSU suppliers. I've seen them as 2nd hand items at local computer fairs though, worth a look if there are any in your area.

Okay, i just sent an email to Eyetech about the ATX To AT adatpor thingy. I have had a look at the guide and pics about the ATX thing, and although i am grateful, i don't think i have the skills enough to do it. Maybe a second look may change my mind! :-)

Cheers,

GRRR!!! Eyetech, haven't even bothered to email me back, despite me emailing them twice!  :-x  How lame is that. I took another look at the instructions on do-it-yourself ATX PSU. But that sort of hacking stuff is way over my head me thinks. Can anyone else fix one up for me, i will pay good money! :-)

Seek and you shall find: AT PSUs at CPC.
I assume that is what you wanted?

Add VAT and I think £3 for delivery to the price.

@Stedy,

Thanks for that link. But i really wan't to make use of the ATX PSU i have got at the moment. I will use that link, or get a replacement from Power Computing, as a last ditch effort.

Cheers

I'm thinking Maplins or a simular type shop will have a converter as well. Its basicly just a plug to make it turn on from a switch.

Hello guys,

Right. I have now got the ATX - AT adaptor thingy (cheers kgrach!). The problem is, i have connected the adaptor to the PSU (i think) but i can't seem to connect the power switch of the original power tower to the loose wires of the adaptor. I have tried, but when i turn on the switch (of the power tower) nothing happens! Have i done this all wrong? Could it be anything fried (like the kettle cable?), do i need to get a porper power switch to fit the adaptor? I will be very gratefull of some replies.

Cheers,

Hi CU

have you switched-ON the rear switch of the PSU? (must be always ON)

What happens, when you put togheter the 2 "PowerON-ground" wires directly?

Ciao

The what now?!  :-? I just connected the bare wires of the power tower switch and connected it to the loose sockets of the adaptor. I take it, it had to be connected to there, as there were no where else for them to go.

Hi CU_AMIGA,

. . .erm!! sorry but i haven't understood quite nothing :-)

The OLD PowerTower switch, had 4 wires . . .right?

In a AT PSU enviroment, it switch ON/OFF the 220 volts AT PSU.

Now you have an ATX PSU, right? with an ATX2AT adapter, right?

Are there 2 wires from the ATX-PSU (the PSU-ON ones), right?

So, only for testing pourpose . . . try to put togheter those 2 wires.

Ciao

You mean the two spare wires on the ATX - AT adaptor. The guy who sold me the adaptor also said the same thing so i take it that's what you mean. Can i use that method as a permenant setup? I will have a closer look at my power tower switch and see if it connects. Thanks for the help. Watch this space!

not . . .but IF the PSU starts in those way, then you must search the 2 PowerTower switch wires (only 2 of 4) that close and open the circuit.

Connect those 2 wires and you'll have a right switch ON/OFF.

Probably, you have chosen the wrong ones. (check with a multimeter which ones open/close)
