I've seen several adaptors for the A4000 to use an ATX PSU but nothing for the A4000T. I have an upgraded AT one in mine now since they use a standard AT supply, but I would like to put a nice modern ATX one in. Has anyone done this or does anyone know of a source to see how I would build an adapter?

How about this?

Nope, thats for an A4000 desktop, I need to setup one for an AT to ATX for a true A4000T
-
Does not the 4000t just use standard AT connectors? Then just buy a ATX to AT adapter plenty of them everywhere for a few bucks.

(green and black lead should be hooked up to the power button).

Since neither are Amiga specific then something like this is a place to start:

Wait what? Whats wrong with mine? It should work just fine.
The one you linked do not have wires for the power button, how will you turn on the A4000T then?
-
The one Som linked is exactly what I need. I did some more reading up and it looks like a standard ATX converter will be what I need. Thanks for helping out.
I have a 500W AT PSU in it now, nothing wrong with it other than the power connectors are limited. I want a nicer one that I can add new leads to that the newer ATX ones people use in gaming rigs go for is all.
-
We also stock an ATX to AT adapter (part number ADAPSU001):

What about missing -5V?
In 2004 ATX 2.01 standard removed -5V from power supply.

I dont think its used for anything. I know in older AT PCs it was used in some of the audio PCI and ISA cards, and I think bridgeboards used it on the Amiga is all?

Believe or not, Amazon sells new AT power supplies:

I picked one up, works fine in my 4000T.

How do you find your parts at Amigakit, every time I look they don't have the parts I want or need, was looking for an ACA 500, finally repaired my A500 went to Amigakit and they don't even know what it is or so their search engine says so. I was happy they had a set of ROMS for my A1200 though. In March my Amiga 1200 turned red, then black then red then black, then black, checked my roms it was hot to the touch and so was my CF card, Don't know what would cause a CF card to get hot and burn up but it did. Well got to go work on my CD32 and SX-1. Works with a hard drive, but not with a CF trying to figure out why.

Amazing! Even a 300w one in stock!

To be honest I would not use anything but good quality PSU's in anything I care about, I have seen my fair share of dodgy PSU fails and consequences afterwards.
PSU's seems to be something many people tend to ignore but it's a cheap insurance :)
Startech seems to be one of those junk PSU's you should stay away from :/
Anyways, glad to help :)

Yeah, I think getting a good Asus or other higher end ATX with an adapter is the route I may go. My current AT is a replacement 300W that is fine, but I want something with better cable management that another AT wouldnt give me.

I can tell you from bad experience that the
Athena Power AP-AT30 300W
are junk. Very hit and miss, i had 7 of them new.. 2 didnt work out of the box, one had solder rolling around inside and low voltages,3 died within a month,and the last one delevloped a dead short.. absolute junk unfortunately.
i suspect the 230W one is made by the same bunch,but i couldnt track the maker down to prove it.
A quality atx with adapter is prob. best,and it gives you the option of 3.3v hack for mediator to use 3.3v cards.
The only problem is many are missing the -5v.

Uh oh, I think the spare I have in inventory is one of these. Looks like I should junk it!

After reading reviews on them I am staying away as well. I am going for the Amikit adaptor and just ordered this to go with it.
