[SOLVED] Multiple GPUs on AMD B450 Gaming motherboard ?

[moataz987]

Hi all, I'm new to mining and I'm mining with a 1660ti at the moment, I was thinking of buying a RTX 3060ti and attach it to the motherboard along with the 1660ti but I have no enough knowledge to know if it would work. after hours of searching and inspecting my motherboard trying to learn, I found out that my motherboard consists of
these slots: 6xPCI Express x1, 1xPCI Express x4, 1xPCI Express x16

The only slot I understood is the x16 which is the huge one I guess which my 1660ti is connected to, From my understanding that the other 2 slots are too small for another gpu to be placed, So I need a PCIe riser connector ? what's the connector type? does it has a specific properties? number of pins or something? What I understood too that the riser is powered by either a sata connector or a molex connector, either a rise that needs a 4pin so a molex is connected directly, or a sata is connected to a converted that turns into a 6pin in the riser.. My power supply properties is the following, it's : VTC 400 Cougar.. One thing is I didn't understand is how many GPUs can I run on my motherboard while considering the power supply I have? And will the riser work with my motherboard or not? and will the RTX 3060ti work on a riser? Thanks in advance and sorry for the long explanation as I'm new to hardware stuff and trying to understand.

	+3.3V	+5V	+12V	-12V	+5Vsb	Total
VTC400	100-240V~ 50-60Hz 6/A	16A	16A	30A	0.3A	3A	400W
120W	360W

you should aid for a better psu, since 3000 series likes 1 pcie power cable per power slot.

But will they work with the current PSU putting in mind that I drop the power limit of the cards when mining to the minimum? Or would that be dangerous to the cards/PC generally?

Will they work? yes. Is it safe? no. aim for atleast good 650w psu and you'll be fine. Also 3000 series love 1 pcie power cable per power slot. so you want at least 3 separate pcie power cable. 400w is very less adequate as it will max the psu capacity which is not good for long use (caps getting hotter). It's better to let the psu still have some room from the wattage max rated, cooler caps better psu performance and longetivity.

With that power supply you risk damaging both of your video cards when it goes.

It is not enough to power the 3060TI properly much less 2 cards.
3060Ti draws 200-220watts
1660TI draws +/- 120 watts
we are at 340 watts for video cards alone not counting the rest of the system.
Being a cheap power supply to begin with ,you are looking at almost sudden failure.
