Omen Obelisk Motherboard

miata54 · ‎04-29-2020

I am considering purchasing an 875-0030qd desktop. I need to know the total number of I/O uSB ports on the MB and what is the difference between USB 3.1 GEN1 and USB 3.1 GEN2 port? If I have resourced the correct info, I think the MB has 4 GEN1 ports and 2 GEN2 ports. Do all Obelisk PC's use the same MB?

Thanks

mainly speed
but you will find many sites explaining this much better than I could do!

I ordered the 875-0030qd with an i7 9700 processor. I was looking at the MB diagrams you sent and notice that there are only two SATA connectors for two HD's. The option on the order shows info for a second and thrd HD. If I had ordered a 3rd HD, would the MB be different?

Hello
I'm not sure I understand what you're saying
I guess it is about this:

https://store.hp.com/us/en/pdp/omen-desktop-pc-875-0030qd-4wp44av-1

The pc can be equipped with a m2 SSD disk, and with the possibility of adding two sata hard disk, that makes three in all!
so the motherboard should be the one indicated in the product support!

please mark the answer if it is appropriate
