let me clear this up again the psu has a 20 pin connector and the board has a 24 pin connector as in the photos why does it need to be measure'd

This is just to confirm that the power supply is the right one but dont buy the adaptor it works only one way and its the 24pin ---> 20 pin.
Your motherboard needs the 4 extra pins to give it power so by going the other way 20pin -->24pin you are ommitting 4 pins

I would highly recommend you purchase the correct PSU as the pin voltages are also different.
The place you bought it might let you swap it for the enhanced one.

Right here we go
You have no choice but to but the new 24pin ATX PSU and it will cost you about £70.
It seems dear but you will be getting a PSU you know that is compatible with your board and its a decent wattage rating (see above Output Capacity 450W Continually )

Thanks Reddevil

Just to put record straight i dont think the E in EATX means enhanced. If you remember in the old days we had the "Old AT" power supply where you actually switched the PSU on switching 240 volts and with 2 power connectors totalling 12 pins then they changed it to ATX where you switched low voltage dc about 3.3 volts to 5 volts which is the common 20 pin connector as we know.
Now they have brought out the 24 pin EATX to accomodate the need for extra power demand required by the high speed processors.
If you think i am talking total crap let me know

Note to ALL ABOUT PSU's

You need to be carefull about the power rating as sometimes a lower wattage rating can sometimes deliver more power on demand than a hight rating one.
Always look at the Current or Amps rating to decide which is better
The higher the power wattage ratting does not necessarily mean a better PSU

Hope this Helps

Cheers

It is advised to use the correct PSU with a 24 pin connector, because of the higher power consumption on some of the wires, but if you have a hefty psu, you should be ok with the convertor. You could always sell the one you have now as new, and get a 24 pin one to be safe.

If the convertor cable melts, then you know you need the 24 pin psu ;)
