hp prodesk 600 g1 sff psu upgrade

[Kami16]

Hi I'm currently trying to connect a smart 430w psu to my hp prodesk 600 g1 sff. I am using a 24 pin to 6 pin Adapter HP ATX Power Cable. I hooked it up last night and my psu spun up but the fan would shut off. The  pc would also beep 4 times with a red light at the front of the case. I was wondering what the potential issue might be, I have seen some mention of the clock not working but it works fine with my default psu. @NonSequitur777 I've noticed that you appear to have experience in this area so any help would be appreciated thank you.

@Kami16,

Welcome to our HP Community forum!

Yes, the ATX power conversion adapter cable you referenced (as specced specifically to include compatibility with your ProDesk 600 G1) should work with any industry standard ATX power supply.

The way this adapter works is as follows: connect the adapter's 24-pin cable to the ATX power supply's 24-pin power cable, connect the adapter's 6-pin "P2" power cable to your motherboard's P2 power connector, and connect a 4-pin CPU labelled power cable from your ATX power supply to your motherboard's white "P3" ("PWRCPU") 4-pin power connector.  Often, you'll have to split the ATX CPU power supply's 8-pin (4+4) power cable in order to create, so to speak, a 4-pin CPU power cable.

Once everything is connected as described, the ATX power supply will power your motherboard, and you can use your ATX power supply's PCIe power cable(s) to power your graphics card.

If you have connected everything as I described, and things still don't work, see if you can use a different ATX power supply to rule out an issue with your "smart 430w psu".

Which begs the question, what is the model of this power supply?

Kind Regards,

@NonSequitur777 It appears that the issue was caused by me not plugging in the CPU power cable. Genuinely thank you for your help. You have revived a budget build in these trying times.
