DIY EPS 8 PIN Connector

[hobo man]

After having a bit of a read here: http://translate.google.com/translate?hl=en&sl=de&u=http://www.modding-faq.de/index.php%3Fartid%3D200&sa=X&oi=translate&resnum=1&ct=result&prev=/search%3Fq%3Dhttp://www.modding-faq.de/index.php%253Fartid%253D200%26hl%3Den%26rls%3Dcom. microsoft:*:IE-SearchBox%26rlz%3D1I7GGLR
And Seeing as I am a bit overdue for a new mobo, would it be pssble to make a 8pin eps addapter by hacking the top 8 pins off a old PSU and wiring them up to a molex or two like this:

Also would it be safe to do this with a single molex connecter or would I be better off with two?

You would be best off with 4 of course. And before you ask: I'm not joking.

The best way would be to not use any adapters at all or just the amount that is really unavoidable, but not more. Soldering some cables could be an alternative.

That would work, but you could also use the normal P4 connector instead

If you have a standard 4-pin, you can add 4 pins easier. Two-molex adapter to add those two +12V wires and run the grounds back as well. You could probably even just round out the plastic. Remember that pins 5-6-7-8 are all +12V, so it really shouldn't matter which one is which.

is using the -5v line such a good idea, wouldn't u want to only use the -12v's

What are you talking about? Who's using the 5V-line, let alone the -5V-line? As far as I can see, noone suggested to do so.:confused:

i was saying that in the picture the -5 volt lin is used, look at the picture. all the 8pin conectors are +12 or -12, the reguler molex has +12 -12 +5 and -5, out of those the -12 +12 and -5 are conected. u wouldnt want to use the -5
at least from what i know

There are no negative lines, only zero (ground) lines. I don't see how it would matter which one you use.

Sorry to say so, but you clearly have no clue.

As Jimbo Mahoney already said, there is no -5V or -12V line on a molex 4-pin power connector. There's only +5V +12V and 2x GND. And GND is pretty much universal. The only thing to worry about on a GND line is perhaps interference(some voltage) on it.

The idea behind using a 8-pin connector in contrast to the 4-pin connector is to theoretically double the amount of current that can flow through the cables in total. In the pic in the first posting the problem is that there are enough (4) GND wires, but only 2x 12V wires are used and just split up to appear as 4. That doesn't really improve the situation. The cable diameter also influences the max possible current. So splitting up one cable into two still has the current limit of the one original cable.
