ATX 20 pin main power cable, 4 pin ATX +12 volt power cable, 6 pin auxiliary power cable

ATX12V 1.0 and 1.3 PSUs have that connector.

My A7M266-D with a Thermaltake PSU.

My 2K2 Dream Machine (almost complete)

Awesome rig! Similar to what i want to make, only my GPU will be Voodoo 5 5500 😀

This is the current plan. I am planning on either getting an SCSI PCI-X controller or SAS.

Processor : 2x AMSN2600DKT3C
Video : 3DFX Voodoo 5 5500
RAM : 4x 512MB DDR1 266MHz
Audio : Audigy 1 Platnium PRO
Hard Drive : 80GB SATA / 40GB ATA
Addition#01 : 2x SATA 1.5 expansion card
Addition#02 : 4x USB 2.0 expansion card

Can you tell me what PSU model that is? I didnt manage to find 6 pin auxiliary power cable PSUs.

As an alternative to finding a PSU with the right connectors, there were also adapter cables made for such a purpose. There were versions both with and without the P4 connector, but it's easy enough to add a molex->P4 adapter if necessary. I don't know if an adapter would be any easier to find in your region than a complete PSU... but it's a possible option anyhow.

If you do go for an adapter, though, make absolutely sure you get the right kind. There's also some that adapt ATX to the Dell type... they look similar, and they will plug in, but the Dell ones are wired differently and bad things will happen if you try to use one on a standard board.

Thermaltake Purepower 480W. I had two. They are 10 years old (give or take). PSUs with these connectors were made around 2000-2003...

Yeah i know that Dells are wired differently 😀

Thanks for the info! I will try to find an adapter or make one.

Also i see, well thats too bad. But amazing to hear that Tt had 480W PSUs back that, really interesting.
Thanks for clearing this mystery for me, much appreciated!

Once the rig is done i will post pics of it.

It's a standard plug on early ATX PSU's, IIRC it was mainly used on Pentium 4 boards with SDR SDRAM.

Ah I wondered about these connectors. I have a psu with atx and what looks like half an AT connector [and the 4 pin]. Not a very high wattage though - ony 250-300w.

It is supplemental 3.3v and 5v. Maybe since this is a dualie but does not have 8pin EPS they need both that EAUXPWR (ASUS name) and ATX12V. Don't want to fry your power connectors (been there 🤣).

Is there a way to get Auxiliary from new power supplies?
