If you can source an AT power supply at reasonable cost, great, otherwise a new ATX supply with an AT-ATX conversion cable is a good option.

Any new power supply you can buy these days should be sufficient for a 486. However not all PSUs are created equal. More info here: A tale of two PSUs

I agree, I use a such an adapter ATX-AT cable on my Packardbell P-120, the only fully AT style power connector computer I have left, had to replace its powersup last year.
Its hard finding an AT-Powersupply that is quality, with atx ones you just need to make sure you find one that still outputs -5v.
Which isn't really that hard.

I use modern ATX power supplies together with an ATX to AT adapter. I simply don't trust old power supplies and they could kill your precious 386 gear easily.

Seriously how do you find quality/new ATX PSU with -5v nowadays? I can't find them anywhere.
I happen to need one :p

New Old stock on Amazon mostly for me. If you look carefully there are more then a few sellers still in possession of older sups that have just sat in there boxes, being sold on there.

Heres an example, but the seller has jacked his price up since when I bought my last one from him... at 20$ 🤣.
Unbelievable he wants 70$ now 🙁

Its a good PSU but not worth that 🤣.
Just try doing searches for ATX 1.3, FSP, forton, etc.

EDIT: wrong thread :v

It is different here in Canada. Most of those Amazon sellers, including the one you linked, won't ship to Canada. So we do not have access to a large part of the New old stock.

In any case finding these things is tedious work. You have to look at specsheets of PSUs to know if they have -5V and often they are not put in evidence.
Another technique would be to have a list and search for specific models. I just tried with the one you linked and could not find anything elsewhere in Canada.

Edit: I managed to find those but that is a funny brand.

Thats interesting, I had no idea Amazon, sellers don't ship to Canada.
But, yea like you said when searching I'd find a model then look up its info, on Google.

Heres another on Newegg, that is -5v.
Not sure if its quality, since startech can be all over the place.

You can easily add a -5V rail on any PSU using a linear power regulator (7905 for example) or DC-DC converter 😀

As far as new AT supplies go. Well its "Athena power" so YMMV

Good Idea, I guess this is what we will have to do in the future too.

I was also starting to consider Arcade power supplies. But those I see would not be powerfull enough I think

They are typically 16A@5v, 4A@12V, 1A@-5V
Mostly weak on the 12V I think,

I picked up one of these recently (ATX 20 PIN to AT P8/P9 Converter with -5V & On/Off Switch & Dummy Load) to use with a non -5V capable ATX PSU - seems to do the trick quite well!

That is some nice piece of converter-kit. 😀

Where is it getting the -5V from?

Presumably a DC to DC converter

Thanks to everyone for the great suggestions, but this solution may work the best for me. I have a new ATX PS without a -5v rail that's just collecting dust. I just bought one of these and will report back once I've had a chance to test.

Yea thats an interesting cable\Idea!

Yeah I am tempted to get one of them too, but I will wait a bit. Looking forward to hear about your experience with it.
