Gpu pcie query

[fudgecakes999]

Hi so i am in the process of buying a gpu (9070 xt) after building my first pc but have a question hopefully somebody can answer, my motherboard(msi b850 edge ti) has a supplemental pcie slot on it which i am currently not using and the gpu(9070 xt pure) i am currently thinking of getting in the next day or so has 2x8 pin connectors and i have 3 from the psu available if i connect the spare pcie to the supplemental slot on the mb will this give the gpu more headroom/wattage to overclock and be more stable or will the motherboard just ignore the extra pcie.thanks.

 

current pc:

 

9700x

msi b850 edge ti

64gb ram

2tb m.2 drive

This is for when you have A LOT of pcie cards on the board and the power of the board may run short. This basically never comes up.

 

So no it wont help you and you have no use for it.

 

 

The 9070xt's already run near max so dont expect much from ocing. The pure is also a silence focused card and are often not the greatest overclockers but great undervolters which usually matters more for running faster!

There really is no need to use the supplemental one.

I sure dont use the one on my B850 Tomahawk Max + 5080

 

1 PCIE 8Pin capable for up to 150w already

The PCIE slot itself is up to 75w normally.

i only ask the question because the pure having only 2x8 pin connectors while using the same watts as the 3x8 connector 9070xt's.

The max power from the slot is standardized so it can't draw more from there anyway.

9070 XT is up to 304W at stock. 2x8 + slot power is potentially 375W already so more than covers it. 3x8 connector ones might be more targeted at extreme overclockers, or possibly the board manufacturer decided not to take power from the slot and use more from other connectors.

thanks for the reply, is there someway of finding out exactly how much watts the gpu has access to.

[Kilrah]

150W per 8-pin cable and 75W from the slot, so 375W as already mentioned. 

Doesn't mean anything about what its BIOS will allow using.
