psu cables incompatible with mobo?

am building a pc at the moment; have got all the components....

look at this port:
http://www.motherboards.org/images/reviews/motherboards/thumbs/1637_p3_4.jpg

I have the same port (except there is no yellow sticker over the end four)..
However, the cable from my PSU which is supposed to go into this port does not go into those end four slots (that are covered by the yellow sticker in that image)..

So, my 'male' port is simply too small for the other.. is this a problem?

You have a 20 pin PowerSupply and a 24 pin Motherboard socket.  the four pin you are trying to use is intended to go into the four pin socket near the processor . . not the main power socket.  

Your best bet us to buy a 24 pin Power Supply . .

That is way too cheap of a powersupply for my taste . . cheap ones often over rate their power and will cause all kinds of issues with the system . .

I am hoping that you are not going to get a cheap 300W power supply for such a nice motherboard.  What power supply do you have currently?  If it puts out 18a on the +12v rail, an adapter is all you need: http://www.audiooutfitter.com/store/84009/ATX2024MF.html

> "If it puts out 18a on the +12v rail" ...

I'm not sure how I would check this..

the PSU is a CASECOM ATX 350--it came with my case lol

on the side of the PSU, it has some table; here's some of it...

DC O/P

 3.3 V  |  5V   |  12V
--------+-------+--------+ ....
 20 A   | 25 A  | 12 A

AC I/P  115/230V  6A/3A


Does that help? Is an adapter all I need?


Thank you :)

just install the big connector from your power supply into that socket ,the part with the yellow sticker will stay closed.
system should boot

Yes, it should work and not cause any damage.  

What other components are you connecting (hard disks, optical drives, memory, video card)?

hard disks, optical drives, memory, video card
+ sound card,

that's it i think..

CallandorCommented:
Well, you might get away with 12a on the +12v rail if you go with a Core2 Duo, since it draws a lot less power than P4's.  You may be limited in how many drives you can add, because they depend on the +12v, and you won't be able to use a power-hungry video card.

well, i have a P4, and a power-hungry video card.
but would running it on 20-pin for a few days until the adapter arrives cause any damage?

you can calculate the power you need here :

well, unfortunately, not all of my exact models and components are available there...
but when I guess an equivalent (say) GPU to my one, and so forth, it calculates little over 230 W.

It should be ok to run it - 10% over the suggested value is a good rule.

Thanks everyone; I lent my friend some money to help buy a more expensive PSU :)
