Your HP Compaq Pro 6300 won't power on after installing the ATX PSU.
Hello, I recently purchased a HP Compaq Pro 6300 but after a short time the power supply stopped functioning. This likely happened because of the heavier Quad M4000 included by the seller, which I replaced with a GTX 1060-125W TDP unit. The seller also listed an HP XPS 580-180W TDP model. I reached out to the seller, who told me it wasn’t possible and blamed the issue on my side, without offering a replacement or further assistance. Deciding that adding an ATX power supply would be wise, I researched online and watched several tutorials to ensure compatibility with the “Apple-like” HP board using two 6-pin connectors. I ordered a 5-12V adapter and connected everything. However, when I tried to power it on, the fans of the CPU cooler, case, and PSU spun briefly before stopping completely. This cycle repeated until I turned off the PSU. I checked the voltages of the new PSU and compared them to the old one—it still worked. I’m unsure what’s causing the problem and hope someone with experience can help. Also, it seems odd that the board displays a 3.6V signal on the pin usually connected to the grey wire. I’ve used this PSU and found these resources:

The PSU appears to be functioning correctly when installed in a PC or when the green wire is shorted. Any advice would be greatly appreciated, and feel free to ask for more details.
Thank you for your message. Yes, I've attempted to start without a dedicated GPU and the outcome remains consistent.
I’ve just attempted every item on the list that I haven’t tried before, but nothing worked.
the psu performs adequately but previously the pc would power up and start in windows. the psu emitted a loud high-pitched noise, causing the pc to shut down and restart under stress. during a fortnite session it released smoke from the back. i removed it afterward but can still activate it by connecting the green wire to check voltage readings and identify its function.
The device is no longer covered under warranty. Are you confident they can assist with setting up a non-HP PSU? It seems they might only be useful if you purchase a replacement. Still, it’s worth giving it a try and reaching out for support.
