Dell's customize motherboard involved lovely Intel® H370 chipset.
CPU power receptor looks like ATX standard with 4pin (2yellow - 2black)

But the system power receptor is an oddball one. There it is:


Please explain the identity of the GREEN, GRAY and WHITE line...

Thank your very much

Green going to black should be power on psu.
Grey sensing for 12V?
White should be 12V.
I have delta server psu soo i can confirm somewhat, but unsure about green and grey.
Take picture of psu label/sticker.

What about cables? It would be great that you could buy cheap 10$ voltmeter.
I dont see sign of 3.3 and 5V.
This seems like dell propiertary PSU.
If you dont get answer from anyone else except me, go on techpowerup, I rarely helped anyone with Dell PC.

^ yeah , certain dell boards take in 12v only , the downvolting conversion to 3.3/5v rails is done on the board itself.

Thanks for the information.
Dell keeps their secrets so well that even pro like you guys can't help

But if I equip myself a multimeter, what should I do next ?

Just an question, do you need higher wattage PSU?
Or what would be your point?

Yes, I do.
I wanna upgrade my potato PC a lil bit for gaming. 400-500W is minimum requirement for current low-end graphics card.
