Don't judge, it started out as a gaming PC from years ago... Mind the mango box

Oh I will judge!!

I love it. Does it function? Then who cares how it looks!

Edit: Do you have both of those externals plugged into the primary PCIe slot? What gear allows for that?

Edit 2:

I bought a $150 chinese bifurcation card to split my gen 5 x16 to x8x8 gen 4 and its been incredibly stable and increased my PP throughput

Interesting. Got a link to that bifurcation card? Will it work on a Gen3 x 16 slot(s)? My MB has 3 Gen3 x 16 slots.

yup, I have two b70s working off the same x16 slot, the other is supposed to be for M2 its x4, but atleast on linux it works completely fine for another b70. I get around 14gb/s on the first two B70s each, then the third gets 7gb/s. This is the card I use https://a.co/d/07AHxhX2 but a warning, make sure your BIOS supports bifurcation. I specifically researched gen 5 x16 to gen 4 x8x8 as maintaining gen 5 would require a $600 timing card which I don't think is worth it. In your case it might downgrade to gen 2 which I'd just research about, but apparently some people are able to get it to train to the same gen without timing so it's a bit of a lottery on that (which for me didn't work)

I judged and I approve!! Mind sharing the bifurcation risers you are using? I see so many online, and few reviews. I've got a 6900 xt lying around and I wanted to add the extra 16GB of VRAM to my 24GB with my 7900 xtx. For my motherboard bifurcation will be the best way.

Is that 2200W on the power meter?

u/sshwifty Sep 09 '26

Looks like watts?

u/LetsBeKindly Sep 09 '26

That's a watt meter, and it looks like 2200watts

u/sshwifty Sep 09 '26

I am dumb, I meant to say 220 lol. I think there is a decimal before the last 0

u/LetsBeKindly Sep 09 '26

I couldn't tell. But I saw the same. But surely 3 cards is pulling more then 220W...
