So here is my problem I had a PSU that has 4 pin ATX12v connector on it for the CPU. I bought some parts and build a PC it was working fine even doe the MB support 8pin 12v connector. I bought a new case and the cable doesnt reach so I bought a 4 to 8 pin adapter and with thata adapter my PC is doing weird stuff without me pressing the power button or anything all the fans starts spinning and stopps and keep on doing that without starting the PC I instantanly swithced to my 4pinATX connector and its working fine now but my PSU is on a Chair next to the PC coz its too short! Why is my PC doing that stuff in the MB manual its says ATX 12V Power Connector and the cable i think is EPS is tehre a difference or why is my PC doing that stuff ?
8pin EPS doesnt work but a 4pin ATX does

Yeah I think something is wrong with that adapter. It has nothing to do with "needing more watts". That's not how it works. Power is not a stuff that can run out. Power is the rate at which energy is being transferred or converted. Since power is the resultant of current * voltage, and current is simply the flow of electric charge which does not run out, power does not run out. Power does not run out, and the power supply can not run out of energy either since the energy comes from the power plant and wall socket.
I know it sounds confusing
just don't want you to get the idea that a power supply can run out of power. A power supply is a charge pump. It causes electrons to flow as current by using voltage.

Your original post is a little unclear.
1) So your motherboard does support 8-pin EPS, correct?
2) Your power supply does not have a native 8-pin EPS12V out cable, correct?
3) The converter cable is a female 4-pin to a male 8-pin, correct?
Can you give me a link to this converter?

1)Yes my Motherboard supports 8pin EPS -Asrock 980DE3/U3S3
2)Yes my PSU doesnt have 8pin12vEPS cable but it has a 4pin one thats short and doesnt reach the motherboard thats why i want the adapter to make it longer and there are no 4to4 pins in Bulgaria!
3)Yes thats Right https://www.jarcomputers.com/p/CASECBL4TO8PINPSU/Prehodnik-4Pin-kym-8Pin-za-PSU?ref=pr

So what precisely happens when the converter cable is used? I know it works without it, but when you use it, what happens?

What do you mean "nothing happens"? You just said that the fans start. So do the fans start up when you press the power button or not?
Yeah sorry it was kinda unclear when i red it again!
So I put on the adapter and when i turn on the PSU all the fans starts without me pressing the power button for the PC and if I Press the power button for the PC the PC doesnt start but the Fans are keep on spinning!

If that was still unclear here is another try from me
:When I put the adapter and the second i give the PSU power the fans on the PC and the PSU starts spinning and the PC cant start up!
Tht must be one s****y adapter
)
Are you sure ? If I buy another one will it do the work ? Or as I red somewhere the PSU needs more Wats for the EPS cable?

3 days after i removed the SD card reader and no problem has occured was that really the problem ? the SD card reader have to be plugged in a USB port right ? I think the only way to find out is to plug it again and see if the PC runs!

It'll probably work. Chances are you moved something while first installing that adapter and that was the surce of issues.
