If the old power supply is working perfectly without any issues (not needing to
press on anything to turn on) then the issue is with that newer PSU. Chat GPT is not wrong if both PSUs have the same issue, that would indicate damaged traces or broken solder joints somewhere on the board. With an issue like that however, it would happen with any PSU, not just a specific one. Maybe I misunderstood your post but it seemed that you said the old PSU worked without any issues at all but the "newer" one required you to press on areas of the board to even turn on. If this is the case and I understand correctly then the issue is possibly with the 24pin power connector on the newer PSU, check the pins and make sure they have not deformed and opened up too much so that they no longer make proper contact with the pins on the board's power connector. This would also explain why pressing in places might make a difference as it would change the angle the pins connect and cause contact to be made. Chat GPT can be useful but I wouldn't rely on it for things like this, it is only as good as the quality of the question you ask and how it interprets it. |

It is interesting that Chat GPT 5.0 thinks it is rather motherboard:

I?™d double-check the PSU first. Even if it powers on, it might not be stable under load. If you?™ve got access to another PSU, testing with that can save time.

A PSU working on one system but not another can still be a bad PSU. Given the other
symptoms you describe that would be my best guess. The newer unit is dying and the other system is simply less demanding, allowing it to appear functional. A PSU is a complicated piece of hardware with multiple voltages and control circuits. Even PSU "testers", especially the cheap ones that just show lights for good or bad voltage can't pick up on things like excessive ripple or voltage droop. When it comes to PSUs the general rule is, "when in doubt, throw it out". |

I got some unexpected results.
I only changed the PSU (and the HDD), and everything started working. It was an older PSU that has just a 4-pin CPU connector, ??and surprisingly, it worked without any issues! However, with a newer PSU ??the one that has an 8-pin CPU connector (and that gave me 5 short beeps a few days ago) ??I had another problem I didn?™t mention before: the system would only start if I pressed on the power connectors with my fingers. Even stranger, it didn?™t matter where I pressed ??the 12V CPU connector, the main 24-pin connector, or even the RAM modules ??and then the system would power on. Without pressing, it wouldn?™t respond to the power button at all. Sometimes the system would turned off on its own. The PSU was firmly connected (I double-checked). Also, both the older and newer PSUs work perfectly fine in another system, as they should. Please let me know what could be causing this issue in your opinion ??a faulty motherboard or something with the newer PSU. Thank you! |

The 5 short beeps indicates the system has completed POST and is simply unable to
output a display. This means that the PSU is providing enough power to power up the board and CPU. If the PSU is providing insufficient power to initialize the GPU however, that could be the problem. The board will function just fine with a single 4pin power connector but generally speaking, most PSUs that only provide a single 4 pin CPU power connector are weak, either very old models with weak 12v rails or cheap and nasty budget PSUs. That said, your beep code indicates a successful POST as I said above so it may not be the cause. Try a different display output from the GPU and a different cable if you have one. Often 5 short beeps is simply the board not detecting your monitor. If your GPU is old, particularly an old server grade GPU (Quadro/Firepro) it may be incompatible with your motherboard, even if it works in a different system (with an older board). |

While you are at it please let me know also if I can use a PSU with a 4-pin 12V connector for my processor, the TDP of Xeon E3 1270 v3 3.5 GHz is 80 Watts.
The motherboard has a 8-pin power connector. |

The processor ??Xeon E3 1270 v3 3.5 GHz ??has no built in GPU comodule, so I understand an external video card is required.
The fan of the GPU is spinning. I will test this videocard in another system. |

5 short beeps indicates that a display was not detected. It can be as simple as
a bad display cable or indicate the GPU is not found by the system. Without your full specs I can't provide much more. |

Please let me know the beep codes for this particular model of motherboards.
If the BIOS is from American Megatrends, then 5 short beeps may be processor failure. But on forums I read it could be "GPU not detected" for ASRock. |
