I'm having trouble getting my PSU to agree with my motherboard, and also having trouble getting my motherboard to agree with my hard drive.

I think it would help if you took a quick look at the stuff I bought, as some of my problems may speak for themsleves, or just skip down and keep reading:

Problem 1: The power supply has a 20-pin power connector that goes to the motherboard, but the motherboard has a 24-pin connector. I don't know if this is a problem or not, but sometimes, almost randomly, my computer will flat-out refuse to turn on. The CPU fan doesn't spin, nothing. Sometimes if I just wait it out a while it will turn on when I push the power on button though.

Problem 2: My hard drive is IDE/ATA, but the motherboard has only one IDE connector on it, as you can see from the newegg pic. I have three devices that I need to connect though: my hard drive, and my two optical drives. Well, it turns out that my motherboard has four SATA connectors on it... and one of my friends just so happened to have an IDE-to-SATA Adapter, which I will refer to as Adapter, with a capital A. It's the kind of Adapter that you plug directly onto the hard drive, then plug a SATA cable from the Adapter to the motherboard. Well, my computer refuses to detect the hard drive, but it detects the two optical drives just fine. The two optical drives are connected to that one IDE plug on the motherboard. Upon further inspection, though, I noticed that I had connected the SATA cable into SATA4 instead of SATA1, simply because SATA4 is closest to the CPU (according to my BIOS, SATA1 is master or something like that)

Anyway, at the current moment the computer refuses to power up. I have connected my HD to SATA1 now (it is labeled as SATA1 in the manual anyway), but I have yet to test it since I can't power it up. I have to admit, though, that I did something pretty stupid. When the computer first refused to detect the hard drive, I thought it clever to connect a regular 4-pin power connector onto the hard drive along with the Adapter's own little power connector. When I did this and tried to power it up, it refused to do anything. In fact, that was the first time that it refused to power up, and I'm assuming that I caused some kind of short circuit that effed something up in the power supply. The 20-24 pin thing might not even be an issue, but I just thought I'd throw it out there. I've also heard that SATA is somehow associated with something called IRQ's, or something like that. I'm thinking I'm gonna have to change some IRQ settings or something along those lines... except it still refuses to power up at this point, so I can't really do anything yet. Any help at all is extremely appreciated.

I suspect that you need to connect the 20 pin & 4 pin connectors from the power supply to the motherboard, JATXPWR 1 & 2. On my MB I have two separate connectors, one is 20 pin the other 4 pin.

Check page 15 on your MB manual for the pin-outs on the MB. You might want to ask a tech at a local computer store to double check on that. I'd hate to see you fry your MB.

I have the 20-pin and the 4-pin connectors in place. Taking out the 4-pin and putting it back in sometimes fixes the power-on problem. I did check page 15, and it only says the following:
---------------------------------------
JATXPWR1: ATX Power Connector
This connector allows
allows user to connect 24-pin power connector on the ATX power supply
---------------------------------------
Then it has a diagram of what it looks like and a brief explanation of what each of the 24 pins is for. Then on page 16 it says:'
---------------------------------------
JATXPWER2: ATX Power Connector
By connecting this connector, it will provide +12V to CPU power circuit.
---------------------------------------
And again a diagram of what it looks like and an explanation of what each pin does. It doesn't say that the 4-pin has to be in place, though.
Any ideas on the rest of the the issues?

Danger. The extra 4 pins on a 24-pin ATX 2.0/2.1 connector are +12, +5, +3.3, and ground. The 4-pin aux connector is a pair of +12V and a pair of grounds. Not sure how that Biostar responds to +12 or ground where they shouldn't go but safe to say you're in the weeds. It's recent, and Intel, so I'm guessing your board needs the extra 3.3V supply. Possibly +12 also. Can't get to Biostar's site to check specs. Safe bet is buying an adapter or an ATX2.0/2.1 PSU.

cyrnel · 07-13-2005, 06:34 AM

I just checked out that power supply. Exchange it. It only provides up to 15A on the single 12V rail. It's doubtful that's enough for your motherboard, before adding a PCI-e video card. (Because that card doesn't have its own aux power connector it draws from the MB which means the MB really needs those extra pins supplied. (and of course, the PSU needs to have enough power to supply) The reason for the redundant pins of equal voltage on a 24-pin connector is so the connectors aren't overloaded. Once you hit ~18A the 12V pins start to desolder themselves.

What do you recommend? This is the cheapest one I could find:

+12V@30A. Would this be enough?
