Help upgrading the HP Prodesk 600 G4 SFF power supply from the anemic 180w and its proprietary oddit

[MisterArthur3]

I own a prodesk 600 g4 sff. The power supply model is L08404. It has 4 pins + 4 pins + 7 pins. The 4 pins are proprietary and go to the motherboard. I have attached relevant photos showing how it looks like. HP's website does not provide an upgrade path for this particular GPU. I have scoured HP's help site and there is a guy who tried updating their 600 g4 sff. He flirted with the model number : L33619-002 . It has an extra 6+2 pin connector for the GPU. However his psu replacement arrived dead and he did not follow up after that. The listing for the  L33619-002 does not mention the g4, it mentions the g3 g5 and g6. Normally, they seem to share parts as they are the same form factor. I cannot be sure if it was dead or incompatible since the thread is dead. The 7 pin connector on the L33619-002 has 3 wires instead of 5 like the L08404. The second image is of the L33619-002. I am trying to upgrade seeing that it is only 180W so it cannot run any decent GPU (I do not have the money for the rtx 3050 lp and the rx 6400 is bad on pci 3. I mainly play rogue lites/likes and metroidvanias so something like a gt 1050 ti would suit me now that more and more games are being made on Unreal and my pc can't keep up)

Does anyone know what I can upgrade to? There is something to do with power from sata cables that I do not get. There is also 24 pin to 4 pin adapters if I get a new psu but they don't mention the other 4 pin & 7 pin. Someone please point me in the right direction.

@MisterArthur3,

Welcome to our HP Community forum!

I addressed your very question in an earlier post: HP ProDesk 600 G4 SFF - HP Support Community - 9146693.

I did come across your post while researching. The 600 g4 ssf's have a power supply model L08404-001/002/003/004. I have seen two posts on  this forum mentioning the L29203-001 instead. See, the dimensions aren't the most important thing. The wiring is. Some PSUs have the same amount of pins: 4,4,7. Except the 7 pin has three wires instead of 5 like the one on the L08404 power supply. The last person to buy an upgrade said it arrived dead. I should bring up I am neither American nor European.  Importing a PSU , paying the delivery and custom taxes only to have it not work and trying to return it would be a major PITA. And way too expensive. 

The PSU has to have the same color wires going to the same pins to work.

I asked on linustechtips forum and they came to the same answer I did. No one could find adapters for the 600 g4 sff. They don't exist on Aliexpress, Amazon or Ebay. Adapters for the G3 and G5 exist. Just not G4. Those 5 wires going to the 7 pin connector seem to be the unique thing about the 600 g4 sff. 

You can read through the HP forum  thread for the other person who tried to upgrade but gave up halfway through. It is called Hp Prodesk 600 G 3-4-5 hw compatibility. Ah, I see you were the guy helping with that thread too!

@MisterArthur3,

And as I remarked in the aforementioned link: "HP is not giving me the tools to adequately ascertain without a shadow of a doubt that the aforementioned power supply is going to work for you." 

Unfortunately, that still stands.

As I have been actively engaged in upgrading various HP desktops, I am all too aware that more often than not when it comes to upgrading PC components, it is hit and miss.
