Psu atx power

[Davros]

Just looking at some am4 boards
and noticed they need
- 24-pin EATX x 1
- 8-pin ATX 12 V x 1
- 4-pin ATX 12 V x 1

Then looking at some psu's they lack the 4-pin plug
whats the solution

AFAIK, 8 pin can be plugged to 4 pin

Usually it's either 8-pin or 4-pin for the CPU power plug on the motherboard. And the 8-pin on the PSU should be 2x4-pin that combine.

Usually yes, but apparently not on the x570 boards

From the board specs

That means the board is designed with higher overclocking potential and requires both 8-pin and 4-pin to ensure stability at higher voltage settings. If you don't have a PSU with both an 8 and 4-pin then firstly ensure the PSU is capable of driving the power requirements and you can get a molex converter to take a standard HDD molex to the 4-pin.

 

[Davros]

ok, but I have a feeling that molex is 5v
I read you need a pci-e converter (so I need a psu that supports sli)
(i used a psu calc and it said 475w)

ok, but I have a feeling that molex is 5v

Standard molex connectors are 12v + 5v wires

I found some psu's with the required 3 atx power cables
A bit more expensive but I'd pay a premium to avoid the f**king about

F**k me
£350
The X570 AORUS MASTER (AMD AM4) DDR4 X570 CHIPSET ATX MOTHERBOARD requires
Internal Connectors:
1 x 24-pin ATX main power connector
2 x 8-pin ATX 12V power connectors

Edit: The cut down version of that board
£210
The X570 AORUS ELITE (AMD AM4) DDR4 X570 CHIPSET ATX MOTHERBOARD requires
Internal Connectors:
1 x 24-pin ATX main power connector
1 x 8-pin ATX 12V power connector

If I go with that board I think I will still get a psu with the 3 atx power connectors because I think 3 power connectors will be a future trend (especially as core counts increase)

Edit 2 :
The middle version of that board needs the 4 pin as well
£260
X570 AORUS PRO (AMD AM4) DDR4 X570 CHIPSET ATX MOTHERBOARD
Internal Connectors:
1 x 24-pin ATX main power connector
1 x 8-pin ATX 12V power connector
1 x 4-pin ATX 12V power connector

edit 3 : Theres another Aorus board thats £299 (bloody hell)
