Found High-Quality AT Power Supply (P8/P9) – For 486 Build

[Tormbo]

Hi all,

I’m looking for one high-quality AT power supply (P8/P9 connectors) to power a 486 system.
Not interested in generic/no-name/untested units — only reliable, OEM-grade hardware.

What I’m specifically looking for:

True AT PSU with P8/P9 motherboard connectors

+5V rail ≥ 20–25A (mandatory)

+12V rail ≥ 6–8A

−5V present (for ISA cards)

−12V present

2–4 Molex connectors

1–2 floppy connectors

Fan must spin smoothly, no bearing noise

No rust, no bulging caps, no previous amateur recap jobs


Prefer these OEM brands (in order):

FSP / Fortron / Sparkle

Delta

Astec

Lite-On

HiPro

Enlight

Compaq/HP OEM (Delta/Astec internals)

IBM OEM (Delta internals)


Output range:

200W–250W AT (classic beige box era)
I do not need >250W units.

Condition:

Must be fully working

Preferably tested recently under load

Clean internal condition (no dust mats or rust)

Original cables intact and not brittle


Not looking for:

ATX units

ATX→AT adapters

Modern generic AT PSUs

Macron, Deer, L&C, Codegen, Akyga

“Powers on but untested”

Units with replaced caps unless done professionally


Location / Shipping

I’m in The Netherlands.
Willing to pay fair shipping inside the EU.
Local sellers preferred but not required.


If you have something that matches, please send:

Model number

Rail sticker photo

Connector photos (P8/P9)

Internal photo if possible

Your asking price + shipping to NL


Thanks!

What about Seasonic? I think i have one, Astec too. I also have one from brand machine, but its a little wider than standard AT power supply.
