having a bit of a nightmare,
Has anyone got this motherboard as I was just finishing off putting my new build together,
And realised I didn’t have the right leads from my psu,
Anyways after searching google for the last few hours and asking in the power supply forum about getting a replacement lead for my Corsair psu.

The MB has a 8 pin 12v and a 4 pin 12v
if I was too use just the 8 pin 12v would this work ok?
I only have (4 pin 12v lead x2)which I can together and make a 8 pin.
will this be ok?
I’m really hoping somebody has this motherboard

The CPU power connector? You don't need the 4 pin, just the 8 pin

Yup join 2 x 4-pin to fill up the 8-pin header and that's it.

What is the 4 pin used for any ideas? in the manual the 4 pin socket is down as cpu pwr 2,
if I don’t use this will this will this affect me in anyway

Extreme overclocking, and it won't affect regular overclocking with air or water cooling.

Job of that 4 pin connector is marketing scam.
Would need very heavy overclocking for 8 pin connector to not be enough.
And likely half the mobos with that 4 pin connector have too cheap skimped CPU VRM for reaching that level.

Thank you, I did see something about it saying it was for ln2 overclocking but thought surly it can’t be
not on a 120 quid motherboard anyway lol

Yeah, can see how it would give you pause for thought. It's pointless on B450.

Its because MSI went super overboard with the power delivery on a lot of their boards, I don't mind so long as they aren't charging a huge premium on it and hey better to have it and not need it, than need it and not have it.

I do wonder though if the rumors of 16 core AM4 CPUs turn out to be real, it may be that suddenly they become very useful
