HELP ME PLEASE I AM SO LOST!!!!!
ok so for weeks I've been trying to find the adapter for my new to me used all in one AI says its a 7pin adapter and everywhere else says its a center smart pin. I pilled it apart as AI said there was a hidden single pin in behind the back cover. I've attached pics of the inner cable and all of the label. Any help would be greatly appreciated. Is it just a regular 7.4mm 5mm center pin barrel 330watt power supply.

The parts list I posted has the power adapter part number and description:
L03557-800 A/C Adapter - GNRC AC 280WsPFC Holmes Straight
The power cord that goes from the wall socket to the adapter is sold separately.
121565-001 Power cord (Black) - 3-wire conductor, 1.83m (6ft) long (United States)
The power adapter is very expensive, and you can't buy it in Canada from the HP Parts store.
There's one on eBay, but it doesn't appear to come with the power cord.
You can also contact HP's authorized parts supplier that does business in Canada at the link below and see if they can be of help.

According to the parts list for your PC, the part # and description of the cable you need is:
L83883-001 Cable - ASSY, DC IN Cable, Volfoni
HP does not sell the cable, but doing a search by the part number on eBay, there are a couple of them for sale.

Im sorry I didnt make myself clear. I am looking for the external power brick that the pc plugs into and then plugs into the wall outlet. It's a cable I am showing in pictures is of the inlet on the back of the p.C I only pulled it apart , because a few computer stores kept telling me that there was a middlepen port inside the computer. So im looking for the power adapter.

Everywhere I am reading. It says that this requires a 330 W power supply. But the question I keep having come up is whether or not it's a 7 pin plug or a center pin smart plug. So before I order anything, because here in Canada, I can buy generic ones and knockoffs. from different computer stores. I just don't want to waste the money or the time for it to come from China and it not be the correct one
