So at the moment i have the standard 24pin ATX plugged in aswell as the 8pin ATX, when is the 4pin ATX needed ? **not talking about the 4pin molex**

Any info is much appreciated 🙂

Not much help but I always go by Tim Taylor more power never hurts rule, just mean that AFAIK there's no harm in having them both plugged in, 4 pin molex included.

Edit: I did hear somewhere here that the 4pin only applies to certain CPU's but I forget the thread it was in.

If you have the jacks available from your power supply It wont hurt anything to utilize all of them. Once you get everything up and running you can always shut down pull the plugs to see if youll run stable without the extra current supplies to save on some electric $$ In all reality if youre not running multi GPU's and your processor/memory doesnt need the extra power it will not draw more than is needed anyways (OHM's law) & (WATTS law) so basically plug them all in if your power supply can support it. That way if you later need to install a device that will need it it will already be there. It will allevieate future problems when installing a device and forgetting to add the power factor...

The extra 4 pin +12V EPS connector will be needed for pushing Bulldozer.

The 4-pin ATX plug is provided on PSUs because low-end motherboards sometimes only have a 4-pin plug instead of an 8-pin.

What Praz said.

I tried using 8 pin and 4 pin and it would not post. The user guide shows using one or the other not both. Page 2-40 shows a diagram using 1. Only the 8 pin in the 8 pin plug in. 2. Using a 4 pin in half of the 8pin plug in. 3. Using 4 pin in the 4 pin plug in. Can some from Asus comferm this or is somthing wrong with my CHV?? Or is it just that my 1090T can't handle it and I'll need to run it that way when BD get installed?? I would love to have the extra power if it is supose to be that way. I sure don't want to kill my hardware if it is not.

I'm not from Asus, but I can confirm that your board not posting has nothing to do with having had both of those plugged in. I have both the 8 and 4 jacked in without issue.

Well I can tell you this. When is pluged in I get nothing. When I unplug it I get post. I cleared cmos and it did not do anything. I guess something is bad on my board. Still would like to hear from Asus on this.
