$50 USD Silicom PE310G4SPI9LB-XR-LP 4x 10gbe SFP+

Bought one last week, seems like a solid card. Based on 2x Intel 82599ES chips.

I wonder if these will fit like a Lenovo M920Q or M90Q?

I don't think they'd physically fit (too long), but thermals would also probably be a challenge. I think these have two Intel 82599ES controllers and a PCIe switch onboard, so the whole card is dissipating something like 20W at full tilt. The heatsink's there for a reason.

these seem... very old?
also silicom has made a lot of passthrough or bypass cards, would this be one of them?

Just buy a Supermicro AOC-STGN-i2S for $20-30. They are flawless in the Lenovo Tiny's.
If you get a rev 2.0 card they are a bit smaller, and you can even fit a small shucked sata ssd drive in there as well

These consume a ton of power. If you're using it as a regular 2x sfp+ card it's better cause it won't even power the second chip most of the time but when your using it as a quad nic expect 28-32w.

I can measure mine in a bit. Its a surprisingly small card.

same chips as a X520-DA2

The board is 165.15mm by 64.39mm, so it should barely fit in a M90Q (max length 167mm), but not a M920Q (max length 150mm).

Also, the technical specs state that it should consume "6W, 0.5A at 12V: Typical all ports operate at 10Gb/s", though I'm unsure if that's meant to indicate total draw or per port (I suspect the latter).

I think you're looking at the X710-based card. The specs for this one quote 20.16 W in SR mode. DACs would likely push it lower, but probably not south of 15W.

Yeah, my mistake. Even worse, those specs list the card at slightly over 167mm, meaning it likely won't fit in a m90q.

Those specs are flat out lies BTW. I've tested mine with 4 dacs and it pulled 28w.

That's the thing with intel NICs or at least the ones I've tried (X520 and X540 and X550) is that their power draw figures are highly optimistic... Or in other words wrong

When X540s get hot enough to shut off you know you're in for a world of trouble and that's only 14W
