What to do? Looking to upgrade PSU, but motherboard has funky slot interface (24 pin mini)


I'd like some advice on what to do next.

I'm interested in installing a graphics card on my older HP computer. I'm interested in the MSI Technologies GeForce GT 610 2GB DDR3 PCI Express 2.0. (I’m open for other suggestions but keep in mind that I’m not a gamer and am just looking to upgrade from my onboard video card). My PSU is not powerful enough (240w) and I believe the card I want has a 300w minimum. I’m hoping you might know of a good PSU I can purchase.

The caveats to the PSU I need are this: My motherboard has a 24 pin mini slot (I tried putting in a 500w psu, but the connecting interface it had was too big and the PSU itself was too big) and I have a slim case. Are there any good 300w+ PSUs out there that can fit in a slim case and can fit a 24 pin mini slot? Will I need to invest in an adapter or even upgrade my motherboard so I have a standard 24 pin slot? Maybe even buy a different case so I can fit everything in? I'm not sure what is possible for me to do at this point with what I have.

Here are the specs to my computer:

CPU: DualCore Intel Pentium D, 3 GH
Motherboard: Hewlett-Packard 0A54h
System Memory: 4 GB
Bios Type: Compaq (4/13/07)
Onboard Video adapter: Intel(R) Q965/Q963 Express Chipset Family (384 MB)

As for the graphics card slot on my motherboard: I believe it’s a PCI express x16. It fit a Radeon R5 230 which had a PCIe 3.0 bus interface (I may be returning this card because it requires a 500w psu). I included a pic of my PCI slots.

Here are some pics I took that may help:

Please let me know if I need to provide any additional information.

Thank you for your time!

  1. You can't use a standard power supply that is a proprietary motherboard.

    Your problem is as mentioned you have an HP and they dont want you to change anything in their crappy setups. You would be better off to build a new system to meet your goals. I know it sucks but that is what happens when you buy HP or Dell.
  3. thanks for the advice! I'll look into doing this
