PCIe Slot: Max Card Thickness (i.e., space between slot & power supply)

Hi Framework Developers and Community!

Based on reviewer feedback and visual inspection, it seems that space is tight between the PCIe slot and power supply. I’d like to ask, what is the maximum PCIe card thickness (the space between the slot and power supply) that the Framework Desktop case can accommodate?

Based on images from the PC World review, it looks like there would probably be enough space for a one slot card whenever they release the case with the PCIE slot hole. And because of the case height I image it will accommodate half height cards. Length wise (with some PSU cable management) you can probably fit a card as long as a mini-ITX motherboard (17cm/6.69 inches). *This is all speculation though*

I’d love to figure out the width of that orange square in the bottom left corner of the motherboard. If we knew that, we’d be able to figure out the space between the pcie slot and the bottom edge of the motherboard, which is where the power supply would be.

9.96mm according to this pdf: Framework-Desktop/Mainboard/FRAMEWORK_DESKTOP_MAIN_PCB_V0.pdf at main · FrameworkComputer/Framework-Desktop · GitHub

There is also a step model of the mainboard with the PCIe port. It should be 6.55 mm from the pcie card surface to the bottom of the mainboard if I got it right.

Another important question is the compatibility with the case on the backside. There is no opening for a card. Maybe those cards without ports could fit if you unscrew and remove the shield but I am not sure about that. Otherwise you’d have to get rough and cut an opening into the case…

Haha, i was just looking at those too! :slight_smile:

I also found these:


The first image suggests the board is 173mm x 173mm. The second image shows that the top left corner of the pcie slot is about 162mm from the top… or 11mm between the top edge of the slot to the bottom edge of the motherboard. I guess the next question is how much space is between the bottom edge of the motherboard and the power supply, haha. Moral of the story: Not a lot of space… but I still wanna find out how much, haha.

Excuse the possibly stupid question, but would it be possible to fit a dGPU more powerful than the 8060S in that slot?

Most definitely not. It can only fit PCIe4.0x4 cards. Maybe I am not well informed but I don’t know any cards with such a PCIe format.

What is possible though is to get a PCIe4.0 to occulink adapter card and get an eGPU. Or maybe via riser cable I don’t know. In any case you will only have a PCIe 4.0x4 connection.

Exactly what @Jiral said - most definitely can’t fit a powerful dGPU there. And even then, for other PCIe 4x cards, we’re literally counting millimeters between the slot and the power supply to see what kind of cards can fit there.

And then there’s the question of where any ports on the card could stick out. I’m really hoping Framework can provide an alternative/up-sell back panel that provides space for the PCIe card ports to stick out.

PCIE x1 half height card should fit, here are some on the PartPicker website: Choose A Video Card - PCPartPicker

I mean, you would need a different case and a different power supply anyway. The PCIe port only supports 25W apparently and the stock PSU does not have any provision for GPU power cables.

Low-profile PCIe cards should fit… as long as they aren’t too thick.

This exactly and also @PenTurDucKenLinE from what I’ve seen on the forum there are mentions of a PCIE slot hole coming in a future case. I’m GUESSING whenever they release the case by itself

@wanderingmeander Oh cool! Do you happen to remember where that discussion is at? Would love to offer support. Darn, I just wish it could come out in time for Batch 7, haha

The best card that fits that criterion on partspicker I could find was a GT 730. The 8060s is 10-20 times faster :wink: and also not limited to 2 GB VRAM.

If you want a dGPU that is better than the 8060s the easiest way is to go the occulink route. You can either use one of the two M.2 ports or the PCI4.0x4 interface for an occulink adapter card, to hook up a modern eGPU (would have to be something better than a 4060m to make any sense)

@wanderingmeander ohhh, haha, yes… ah, well, at the very least I feel seen :smiley:

Dawid Does Tech got that to work: The Future Is TINY: AMD Framework Desktop

To be honest, I bet a GPU thunderbolt enclosure could be made that sits under the case and has a expansion card shaped protrusion on top to plug it into the desktop. You’d need another PSU though.

That’s a good video!
