that the way we have hooked up devices can affect if the psu powers up and down correctly?

 

if so i have if i remeber correctly wired mine as follows

 

1. runs the FDD on the MOBO

2. Runs the PCI EX GPU

3. Runs as follows 2 molex which power both dvd rw and r these also use 2 pass throughs to power 2 case fans

4. Runs the FDD and OS HDD only

5. Molex Runs 2x sata Drives only

6. runs 2 fans and cold cathodes

PSU is modular

I've got to run and will be out most of the day.

 

Do me a favor please. Get the technical info on your PSU available, hopefully through links you can post.

 

I'd like to see what 12V rails are assigned to which connectors and if there are any minimum current requirements for any rails.

 

Once that is done I'll need to know exactly which devices are attached to each rail.

 

The Yellow 12V leads should have a color stripe to show that a different rail is being used.

 

Thanks.

And 24 pin power connector is seperate.

I read interestingly on OCUK about someone else with this issue and they RMA'd their board and got another and the problem wasn't evident on the replacement. He says that the old board was revision RAA0 and the replacement was RA02.

 

Our problem boards all seem to be RAA0...................

Once I approve your RMA it doesn't take more than a week or so to process once it arrives here. Sometimes it takes a bit longer if the problem is more severe and multiple components need to be replaced. On average it's about a week thou, as we push the individual RMA's from end-users to the front of the repair queue.
