I'm searching for a straightforward explanation about power supply connector sizes and labels. I own an older Dell PC with model L235P-01, and I suspect it might be faulty. I ordered a tester from Amazon because the power supply has a big 24-pin socket while the motherboard connector is small—about 52.25mm versus 36.75mm. I have a few questions:
1. Is there an adapter available to convert between these sizes, assuming the same pinning configuration?
2. Why isn't this difference widely discussed online? Am I missing something?
3. What are the official names for these connector types?
What specific Dell model do you have? There are some adapters available, though they are not generally advised. For instance:

Dell typically employs its own connectors, which explains the situation.
The only unique aspect I notice is the physical dimensions of the connectors. I haven't found any comparison or details about this size variation online. It seems to be a direct pin-to-pin setup. Both 24-pin versions exist, but one measures 52mm and the other 36mm. My Amazon replacement PS has just arrived, and the previous supply was faulty. The system is operational now, yet the difference in PS MB connectors is puzzling me.
It appears to be a typical Dell proprietary connector issue. You may find more details by checking the service manual for your specific model. I also came across this link: https://www.amazon.com/Hilitand-Standard...B09QKH9M5P
Exactly! The distinction lies in the fact that the bigger model is just the standard ATX connector, while the other is the mini ATX connector. This isn't mentioned in the PS descriptions, it's just SFF (small form factor). I believe this applies only to Dell products. I only use refurbished Dell PCs. Thanks.
