[SOLVED] PCI > PCIE adapter

[Fanax]

Hi,

Motherboard Intel DH61SA doesn't have PCIE slot for GPU, so I bought an adapter from AliExpress (shorturl.at/duR24). Is it possible to connect GPU RX550 with this?

No that is a riser extender not a adapter.

Wrong adapter.
That part in the picture goes into PCIE slot.

Your board has PCIE x1 slot (small size black color). Use that for graphics card with PCIE x1 riser cable.
Note - PCIE slot on the riser cable is with open end. It's possible to attach PCIE x16 graphics card to it.

No. That is not a PCI to PCIe adapter, that's a PCIe x8 to PCIe x16 adapter. And you will likely have a bad time with a correct adapter; it doesn't increase the bandwidth and PCI's maximum bandwidth is dwarfed by even the first generation of PCIe, something like 15 years ago now.

Thanks for fast answers

On a side note, if you're trying to adapt a PCIe device into a PCI slot, it won't work:

• PCI operates at 133 MB/s. PCIe 1.0 x1 is 250MB/s. I would argue graphics cards at the minimum need PCIe 1.0 x16.
• PCI uses parallel signalling, meaning all the bits are sent at once. PCIe uses serial signaling, or the bits are sent one after another

So not only would you have to deal with a much slower bus, there would be extra overhead converting to and from parallel and serial. So what would be the point?

There are PCI to PCIE adapters too.
They just look like this:

And here's why this is a scam, based on the assumption this is a PCIe x16 to PCI adapter

• Reducing a card that would at the minimum require 4GB/sec of bandwidth down to 133MB/sec sounds like a great time.
• PCI can only supply a maximum of 25W. x16 cards are expected to draw up to 75W from the slot.

Maybe this would make more sense if it was really a PCIe x1 to PCI, because at least the power requirement would be met. But you're still going from at the minimum 250 MB/sec down to 133MB/sec. I honestly don't see any application where using this would make sense where you couldn't just get a PCI card instead.
