HP Recommended
Operating System: Microsoft Windows 11

Hi,
I have an HP Z2 SFF G4 laptop with a faulty motherboard, as well as the original processor, an i7-9700.
I've found a motherboard at an original parts store that I believe is compatible.
The one in my laptop is part number SP# L55875-601, and the one they're offering as a replacement is part number SP# L13216-001.
At first glance, they're almost identical, except that the faulty one (SP# L55875-601) has two 4-pin power connectors above the VRMs, while the one they're offering (SP# L13216-001) only has one 4-pin power connector above the VRMs.
I asked at the store, and they assured me it would work perfectly and is 100% compatible with my laptop. It seems mine has a dual connector to power a more powerful processor like a Xeon.
My computer came with a power supply with
Part No: 942332-001 -> MODEL PA-3401-1 and a maximum power rating of 400W.
My question is whether the information I have is correct.
Since I haven't been able to test the power supply in the damaged computer yet, I'd like to know the Part Number, if one exists, for a compatible power supply with only one power connector above the VRM.

Thanks.
Regards.
