Hey everyone,

i d like to upgrade my 3060 to an 4080 Super which will barly fit inside the housing.
As is was searching i ll need a new PSU of course as well.

Now i have the Problem to Choose one as the Mainboard appears to have 2x4 Pin 12 V (12V ATX written on Mainboard) and a 6 Pin with ATX on the board written.

I m struggelin to find a fitting PSU as they dont offer the Pinning i need. Or am i just wrong and an standard ATX will fit somehow?

Thanks ahead!

No, a standard ATX supply will not work without a lot of creative cabling. The system is designed around the newer ATX12VO supplies. None of the PO3 models come with a supply larger than 500W, which works fine with a 3060 or 3070. To get a larger supply I believe you will have to build a set of adapter cables and choose a larger supply that has a single rail 12V design with appropriate power.

So meanwhile i found the bei quiet! Pure Power 12M PSU which offers the 12V 4+4 Pin.

What i m worried Abt is the 6 Pin of which 5 are used, 2x 12V / 2x Gnd / 1x 2.6 ( probably 3.3V)

If i found the right Page it says that an ATX 6 Pin in addition to a regular 24 Pin.

But i did Not find anything how the PSU will get the PSU on Signal?

Can i Just use an Adapter to Bring the voltages of the 5 Pin to the Board or do i Need smth more?

Here are the pinout for the connectors:

Note the PS_ON and return GND on that 6-pin. They should be connected to the power button.
