Question I need help with issue with built computer

[ShazzyQ]

So I recently ran into a problem when building this computer... it was a prebuilt off Amazon for like 400$ yeh trash I know. It was a am3 socket. I upgraded the motherboard to a z370m ds3h from gigabyte and put a 1050 gpu and some ddr4 ram, left the same HDD, literally only changed the mobo and everything needed to be compatible, I didnt add any cables, I literally unplugged all the cables and plugged it into the other mobo. This is what happened, I need some help to fix this issue because I have no idea whats wrong with this

So the PSU was apart of the old prebuilt that I purchased, The CPU i put in there is an i3-8100.

Cpu is compatible but that psu is probably not adequate.

What about the 8pin cpu plug?

So none of that was plugged in beforehand on the old board so it probably is the PSU, any decent budget recommendations?

Wait actually there was a 4 pin connector that was on the old board so is it possible that a 4 pin can go into the slots you are talking about even if its like a 4 pin slotted into an 8 pin?

Ill be honest, i dont have the PC with me right now but I know its some random brand made for budget im assuming

Had a look at your motherboard manual, it doesn't say 4pin is optional. Given the assumed age and colour of the wires, i wouldn't attempt completing your pc until psu is replaced.

Yeh makes sense, looking at the parts being decently new then that PSU just seems like itd be odd one out . Thank you for the help and recommendations
