Why is a correct 20 to 24 pin connection not being made?

[Mike89]

I read all the hubba on the 20/24 pin thread that ended up getting closed.

 

I have a question I didn't see addressed in that thread. The 20 to 24 pin adapters I have seen simply leave the other 4 pins empty.

 

Why can't a 20 to 24 pin adapter be made that just takes the 12v, 3v, 5v, ground (which I understand that's what the extra 4 pins are) from the existing 20 pins and duplicate them in the appropriate 4 extra pins?

 

Would this not solve the problem? All the proper voltage would then be in ALL of the 24 pins instead of in just 20 of them. Of course I'm talking about if the 20 pin power supply has the appropriate wattage to begin with like say a 550 watt.

Because less than a hand full of 20 pin power supplies out there have enough juice to work ok under those circumstances. Drawing amps from the already loaded rails could prove to be dangerous as well.

 

I know people were able to mod the 20 pin ATX connector from an Enermax EG651P-VE 550w into 24 pins, but this is a power supply out of the ordinary. I have one of these, and I prefered not to risk it or my system and bought a native 24 pin one for my DFI.

 

DFI motherboards aren't like other brands that do not require the extra 4 pins, Asus A8N-SLI for example works ok just with 20 pins connected... but these Asus mobos aren't as tough as DFI, not even close.

 

Good luck.

I can agree with that assessment in some situations. Like if SLI was used, big time overclocking, computer loaded to the hilt with big power load extra components.

 

Under what I would call normal circumstances like say a couple of IDE HDDs, 2 DVD/CD drives, a few fans, no overclocking, I would think a 20 pin 550 watt power supply would be plenty using the method I mentioned earlier (a true 20 to 24 pin adapter with all pins active).

Mike89,

you might as well ask why does technology move on. 24pin psus have been around for almost 2years i bought a new psu to run my 754 rig around june 2004, a tagan 480 which was 24pin.

 

So there should be no suprise that current mobos expect & need 24pin power connections.

 

You make a reasonable point re the 24 pin adapter i guess a molex & adapter to a 4 pin might have been made to plug into the back of a full 24 pin plug but it didn't happen.

I found a connector like the one you mentioned on ebay about a month ago. Used it for my friends Asus board w/ a Chieftec psu. Works fine, but he only runs a non-overclocked Venice, a 6800gt w/ passive cooling, one IDE HD, and two burners. I don't think Id risk it w/ my setup.

I have this adapter. It has only one empty socket.

Under what I would call normal circumstances...

do you think your average Jo Schmoe out there would know what a "normal circumstance" is? no, i very much doubt it. they would see that they need the adapter, go buy it, disregard any warning labels, plug it in, get a catastrophic meltdown (in worst case situation), then sue someone. no one wants that. (i am a computer programmer, trained to think for worst case scenarios. :cool: )

The problem being that most 20 pin supplys. the wireing used in them are not Big enuff to supply the amps needed. so the adepter put to much load on the little butt wire witch then couses heat and supply brake down

i wish they showed the back side of that packaging, i wonder if there is any kind of warning label or not.

I can think of at least one guy that purchased an FX60 and Venus but used the '680 watt' power supply that came with his tower and wondered why it didn't work...

 

So Joe can certainly be ignorant with or without money, which is the weird thing to me. If I were an idiot with money I'd buy the most expensive power supply along with the most expensive processor and motherboard...

Mmmm...shiny....

 

And who can complain about the smoke and sparks?
