I have a A7M266-D ASUS motherboard with dual Athlon processors. Every so often the computer will just shut off. May go three or four days, then it shuts off. Since this computer is seldom used, I have only been there once when it happened: the mouse froze for a second and then click, the computer shut off.
Turn it back on and it might go for several more days.
I have a 500 watt power supply with two fans; there are also three fans in the case. All of the temperatures I can monitor seem to be fine.
I am suspicious of the power supply, so......
I bought a new supply, got home, and found that my motherboard has a 6-pin aux power connector which my NEW power supply does not have. And then I did a little research and I can find no power supplies so far that have that 6-pin connectors.
Any suggestions???

Thanks for your help,
Dave

Welcome to TSF:

I am totally at a loss as far as what you are seeing for power connections for your mobo

Here is what the asus says about the PSU needed fro your motherboard

"This dual-CPU ATX motherboard uses a standard power supply and supports up to"

The only advice I can offer you is dont get suckered on a generic PSU / buy an ENERMAX > 1st choice Antec > 2nd choice good quality PSU of 550 watts search on ebay or buy from newegg.com

both of these brands of PSU come with all forms of ATX connections to accomodate almost anything that accepts a "standard" PSU Just be sure your PSU purchase is version 2.03 compatible


asus website also states
The minimum requirement for full-power loading is a 400 Watt ATX 12V power supply; minimum requirement for +5V/3.3V is 180 Watts; +12 Volts requires 15 Amps; 5VSB requires 1 Amp. Also Ensure that the ATX power supply can put out at least 10mA on the +5 Volt standby lead (+5vsb). You may experience difficulty powering ON the system if the power supply cannot support the load. For Wake-On-LAN support, your ATX power supply must supply at least 720mA for +5VSB.

Here is modo pic

Here is mobo pic; black connector (circled in red) is listed as an aux power and there is a connector (6-pin) coming from power supply to it.
Thanks,

Have a look here .I think you need to follow linderman's suggestions on power requirements for the different rails but the link shows the connectors needed for that board.

Thanks

Looks like what I have is a server MOBO, and it looks like it would be more logical to upgrade the mobo and processor and memory than to try to buy a power supply with the AUX connector.
Will keep researching.
Thanks.

Huh ?????? buy another mobo , cpu and memory ?????????

your server mobo is a great quality board / server boards are more stable, better cicuit protection , everything about them is better but more $$$$$$$

you are going to have to get a better PSU no matter what you buy unless you are willing to downgrade to a 1.4 GHZ P4 ????????

there is nothing special or weird about the power requirements of your mobo ???? just get an enermax that version 2.03 compliant thats 500 watts or better !!

Okay, then what is the 6-Pin aux power for??

I mean, it is there, and it is connected, and every "server" power supply that I found has a 6-pin connection.
Some of them I can afford, in the $99 US range.
The Enermax ones with the 6-pin connector was upwards of $250 US.

BTW, this time around the computer has been going for 4 days without shutting off. Weather is getting cooler? Or maybe I am on the wrong track? Any other ideas about what might be causing the problem?
Thanks,
Dave
