    Asus A8N SLi - Power Problem? Defective Borad?

    There are known power issues with the cards, but I can assure you that replacing the PSU will make no difference, your only running two 6600's. a Bios udate to 1003 may sort the problem, but ensure that what PSU you do have has good 12V Amp raiting if is a dual rail and if it's single it is as...

    Asus A8N SLi - Power Problem? Defective Borad?

    I will recieve the board and cards back on Monday, then I'll RMA them for a refund. Has anyone had any experiences of running the XFX 6800 Ultra on the asus board, I know it has two power inputs 4pin molex. I'm tempted to get em as they appear to be the only stock of 6800 cards in the UK atm.

    Asus A8N SLi - Power Problem? Defective Borad?

    This board must be defective. I have left the CPU out, RAM out, and connected one GFX card. Same scenario, just a flash of the GFX card power LED. I've got an RMA number for Chillblast.co.uk, it should get there on Wednesday.

    Asus A8N SLi - Power Problem? Defective Borad?

    Those are the serial numbers I have on the card. They are SLi certified, neither are getting power in single mode atm. Would it harm the computer to connect the motherboard up with no CPU? and what if I connected the GFX card not in the PCI-E socket to see if it gets power this way?

    Asus A8N SLi - Power Problem? Defective Borad?

    The PSU has it's own native 6pin 12V power. I have tried this along with the 6pin to 4pin molex adapter. No effect, no matter what combination :(

    Asus A8N SLi - Power Problem? Defective Borad?

    I'm using a DVI-VGA adapter. However I'm not worried about connecting the GFX cards up yet, as I know I wont get a signal cause the power LED's on the cards don't light, still getting a mere flash. Strange thing is, my 1st board, would allow power to the cards randomly upon turning on and...

    Asus A8N SLi - Power Problem? Defective Borad?

    Thanks for the advice, I've done what you asked. I've tried the board on a table, connected to the case, and with and without screws...... I'm just lost. Your right, it seems too much of a coincidence and I dont know anyone else with a problem like this. Only psoitive thing is scan...

    Asus A8N SLi - Power Problem? Defective Borad?

    Yep, both cards have a 12v 6pin power which is connected, I have tried disconnecting and connecting this plug for various boots, and the same with the EZ, all possible permutations and combinations. Bios update had no effect, this problem is before the bios can have anything to do with the...

    I have noticed the CPU fans spins slowly and then to full speed after about 5 seconds, I guess this should happen.

    Asus A8N SLi - Power Problem? Defective Borad?

    Using the Tagan atm, no change :( Will altering the CMOS have any effect? Problem seems too fundamental, no power to the cards from the second you press the ON switch, just a flash of the LED's. I'm even getting no spin of the heatsink fans. The cards have there own power input, so why...

    Asus A8N SLi - Power Problem? Defective Borad?

    See what you think of this guys......... I'm aware of the high power demand that the Asus A8N SLi motherboard requires and it seems asus were unaware of the peak load on the 12V rail. Hence the latest bios updates which apparently slow the peak power demand on the PSU and cure about 90% of...

    It should automatically recognise them....... However make sure you dont use the western digital secure cable and expect it to deliver power, cause it dont!! use the molex aswell

    A8N-SLI Deluxe: many defective boards identified

    It seems loads of people are using and getting away with dual rail PSU's, like the enermax. I think power can be a problem, but if your getting problems like mine, I think it's hardware

    A8N-SLI Deluxe: many defective boards identified

    Not all the problems are power related. I've checked loads of posts and people are running all sorts of the demanding setups on dual or single rails. Sure, you need a good power supply, but my problem goes beyond that...... On my 2nd board, still not power getting to the GFX cards...

    You have to use the Molex on the mobo or the red light will show and wont run, I have the 6800GT's and try to power them using the molex the the 6pin power.

    I have to cut in, I dont know how many people are having problems with this board but it is a complete joke!!! I'm on my third motherboard, and still cannot get power to the GFX cards, so a bios update is not an option as no display. Perhaps, one in 30 times I get power to a single GFX card...
