MSI MAG X570 Tomahawk Wifi ATX

Count_Zero99uk · 18 May 2021 at 11:07

Hi,

Was just putting my pc parts through a site to check compatibility and a strange thing popped up.

" The MSI MAG X570 TOMAHAWK WIFI ATX AM4 Motherboard has an additional 4-pin ATX power connector but the Corsair RMx White 750 W 80+ Gold Certified Fully Modular ATX Power Supply does not. This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it. "

Im running the R7 5800x, 32gb 3600 ram, and hopefully a 3070/3080 gpu.

Do i need to be concerned about this cable? If so, could someone recomend a white 750 watt psu that will fit.

Many thanks as allways
B.

You will be fine.
I run mine with one 4pin atx, and the secondary is only needed in the most extreme of overclocking situations.

According to the spec it has 2 x 4+4pin eps so you will have enough cables.

Not needed, I have the same motherboard with a 3900X, and only have the main 4+4 pin connected (I left my extra PSU cables at another place so couldn't hook it up). Had no issues with my system at all.

Fantastic, thanks for the info. Another question does this run with the Ryzen 7 5800x out of the box, or will i need to flash the bios?

Officially you'll need to flash the BIOS, but tbh the 5000 chips have been out for a while now so most boards, unless sitting on a shelf for months, should have a compatible BIOS. It's easy to flash though and can be done without a CPU.

I bought the same board a few weeks back. It came with a "AMD Ryzen 5000 Desktop Ready" sticker on the box. No flash needed for my 5600x.

Hi Guys,

Would you be able to advise, please?
My bios version is 7C84v13, will I need to flash the bios to run it with the Ryzen7 5800X?

Many Thanks in advance.

That's a really old bios from September last year so you're definetly best updating before trying to run the 5800X which was released last November.

Thanks mate. Will I need to that with or without the processor...? I'm still waiting to buy a Graphic Card though.

You can update the bios using the flashback feature so you don't need a CPU installed, all you need is the board connected to a psu.
