I have upgraded my graphics card and needed to also upgrade my power supply unit - but the connectors on this motherboard are different than what comes with the PSU upgrade.
I'm unsure of what the small 3 wire connector labeled "12v_in" is used for. The 4 pin cpu and 4 pin main are explanatory... but what about the tiny one? I can find no info of it online.

I don't have access to your specific model, but I have a similar one in the same case.
You should be able to trace the wires coming out of the existing PSU and see what they are connected to.
The 3 wire 12 volt is probably connecting to the ATX Fan 1 on the motherboard.
Those desktops use a proprietary small form factor PSU with its own wiring setup.
A standard PSU wont fit.
That series did also come with a 500w PSU

I found it for another model with the same motherboard as yours...

I tried using an EVGA 600 w power supply unit - I ended up needing another 4 pin connector as this board has ONE 4 pin atx style connector on the board labeled 12v MAIN, and another labeled 12v CPU. I then had a ribbon cable from the PSU to the 8 pin on the GPU - but even with a MOLEX to 4 pin adapter (aka all four pin connections on the mobo were made, plus the connection on the gpu) the computer would NOT turn on.
I notice that 500w psu you linked to is on back order at the moment - I'm trying to find something within my new gpu's warranty/return period! I really wish I knew HP made these impossible to upgrade prior to purchase 😕

"I really wish I knew HP made these impossible to upgrade prior to purchase"
Ya sorry about that, lesson learned now. Ready-mades like HP and Dell, etc. are not a DIY friendly setup. They are intended to be used as-is off the shelf. You're not the first to find out the hard way.
Let me know if I can help you further.

I'll try that when I get home, I did notice that when I unplug it and boot up fallout 3, it ran like crap. I assumed it was providing some power to the GPU the mobo came with.
Any idea why when trying out the new evga 600w supply, the computer would not boot up? Come to think of it, it seemed like the power supply unit never came on, since the fan never began to spin.

That is a BERK motherboard. It uses a proprietary PSU. There is no documentation.
You have sent an excellent photo, superior microphoto clarity. :clap:
That socket was hidden in the EOL document.
Please send me a PM, I wish to discuss other pictures with you. There is one area of the board that NO-ONE has a clear un-shadowed photo. You could be an asset in discovering all the sockets on the BERKS, if your willing to do the photo's.
