New Inspiron 3020S Power Supply Adapter Compatibility

I want to change the power supply to change the current 180W power supply to another one of like 500W, or enough to power everything plus a GeForce Rtx 4060 low profile. But the regular power supplies are of 24 pins, and the motherboard only takes 8 pins, so I was wondering if this adapter would work in my New Dell Inspiron 3020S, since this model doesn't appear in neither the ones that qualify nor the ones that doesn't. If it's not compatible with this model, are there any other options I can consider to upgrade my desktop with the mentioned graphics card? It's ok if it's a new power supply that doesn't fit inside the chassis, since it has to go outside anyway by the amount of space it takes the graphics card. I want to make sure I get everything right to not harm the device. Thanks for your attention, I'm looking forward to your reply.

Unfortunately that 24 to 8 pin adapter is for older Dell and not compatible with new Inspiron 3020.  No known adapter exists for sale.  You can try a 500w Dell psu known to work for Inspiron 3910 and 3020 tower.  I think it will likely work with Inspiron 3020 SFF but the 500w psu is too wide for SFF case.  500w PSU can fit inside but it extends beyond the width of case, which means either side panel has to stay off or psu needs to sit outside case.

user positive evidence: 500w power supply option compatible with the Inspiron 3910. Part number: TPX56

@redxps630​ thanks for the information, I'll try to get that PSU, and as soon as I get it, I'll inform on how it works for future reference.
