I need a power supply with a 6+2 PCI connector for my TP01-1023w

[duckman75]

I just purchased a TP01-1023w and want to put a graphics card in that requires PCI power. The 180W power supply (L81008-800) in my system does not have the connector, as it is not powerful enough. I do not want to have to spend money on a neutered GTX 1650 or other graphics card that doesn't require a PCI connector, when I already have a GTX 1660 Super.  

I have already searched through the forums and been directed to Power Supply Cross Reference for specific models (even though it does not reference my model desktop or motherboard) and I have found the following power supplies 942332-001, L04618-800, L669242-800, and L05757-800 on this list on eBay.  My concern is the 7 pin connector for the motherboard. These power supplies have either 3 or 7 wires on this connector. One seller on eBay stated that they are not interchangeable (7 wires cannot be used on a system that had a 3 wire, and vice versa).  My power supply has 4 wires on this connector, and I cannot find a proper cross reference about this specific connector. Will I damage the motherboard (BAKER) if I haphazardly install one of these "compatible" power supplies, even though the 7 pin connector has a different number of wires connected?

I do nopt like to be the bearer of bad news, but the following applies in your case.

The PSU connector on the Baker motherboard is proprietary.

It is not a standard ATX type PSU connector.

There is only one standard power connector on your PC's motherboard and it is only for the processor.

If your objective is to make a gaming PC out of your desktop PC, You have chosen a PC that is unsuitable for that purpose.

The video shows what the standard PSU connectors on an ATX or microATX  motherboard look like.

I understand that the power supply is a proprietary HP product. The re are (2) 4 pin connectors supplying power to the motherboard, and that the 7 pin motherboard connector is specific. My question is relating to the number of wires on the said 7 pin connector. I have read in other threads that someone was able to install an HP 500W L05757-800 power supply in a desktop similar to mine (I think they even mentioned having the same motherboard).

My question is specifically referring to the 7 pin connector. Will a power supply with more wires connected to the 7 pin motherboard connector damage my motherboard, or do those pins tell the motherboard that more power is available?

Connecting something that was not delivered with your desktop PC to a connector on the motherboard is a risk, so yes, it may damage your PC.

It is unlikely that someone here will tell you that it will work, since we are pledged do "do no harm". 

That is the forum philosophy, mandated by HP.
