okay i just bought a new motherboard today at my favorite computer part store. i got the Asus M4A78 Pro. to replace a dead mobo that was killed by..... a bios update........ dont ask on that one. now this system has a 550w power supply. it also has a amd phenom II x3 720 which is a 95w cpu. i have unplugged everything else and was going to take a look at the cmos settings, i had a few fans hooked up as well (2 to be exact) and the system will not turn on, so i unplugged the fans and tried. it worked! kinda..... so i have tried scouring the interwebs for the power reqs for this board, anyone able to give me a hand ?

and if i confused anyone please ask questions thank you in advance.

Hi,

I have a few questions:

1. Is your HDD Sata or IDE?
2. Are the auxilliary fans powered from the MoBo or the PSU? (I assume you have not attempted to power up without a CPU fan?)
3. What video card are you using?

Please go into the BIOS:

1. Is the HDD correctly recognised?
2. Does it appear in the boot sequence options?

so i have tried scouring the interwebs for the power reqs for this board, anyone able to give me a hand ?

The MoBo does not have any power requirements as such, other than the odd LED or two. The power requirements are from what you attach to the PSU either directly or via the MoBo.

Assuming that your PSU is in good condition and is of a good quality, it should be adequate.

At this point my gut feel is that your MoBo/BIOS is having difficulty with an IDE HDD, as that is fairly common with modern boards. Basically they assume that you have SATA, and the IDE string is for DVD/CD devices etc.

I have usually resolved this by adding an IDE to SATA Host Controller and making the DVD/CD string the IDE Primary.

Obviously you may have a quite different problem, but this is the most common one that I have encountered.

Acutally ive figured it out, and sorry it took so long to rply, the issue was the computer is in the Antec 1200 case, the onboard video card pulls mor than the last one, and there were more slot by far on this board, plus that board was bad. so i did get it too bot by adding a larger powersupply, replacing the board. and everything worked fine. sorry it took so lomng to me reply
and i had gone from a old modded case to an antec 1200 so i could have more room.
