power supply questions
Hi,
I work at a night club and we have a lighting control board that has two mother boards. The other day it wouldn't try to come on at all, acting like it wasn't getting power. So I made sure it was getting power, unplugged and plugged it back several times, and tried starting it several times. Finally after a number of attempts it started up and ran fine, but a couple of tech people said it sounds like the power supply is going bad. It has a HIGH POWER® HPC-360-302 DF power supply. If I remember right it has five connectors: 1 twenty wire, 3 four wire, and 1 two wire. We tried replacing it with a newer type from Micro Center, and had to use an adapter to try to make the two wire connector work. It looked like everything connected right but it never would boot up with that power supply, and said it needed us to insert a system disc or something. When I put the old power supply back in it started up fine again. Can anyone let me know what happened, and suggest what to do if we can't get another power supply just like the one that's going bad? I'm afraid it has been discontinued. Thanks for any help! David |

David It doesn't look like anything special to me, and it doesn't appear to be discontinued.... http://www.highpowersupply.com/produ...pc360302df.htm and http://www.atxpowersupplies.com/630-...-HPC-360-302DF and http://www.supernotebook.com/power-s...p?psupart=3358 -- Charlie Hoffpauir Everything is what it is because it got that way....D'Arcy Thompson |

IT did FIT though ? Can you give us a link to what you have and details. On the good PS , check the voltage across those 2 pins and compare. I'd go to the website for the "lighting control board" / motherboard company to see specs. |

The 2 wire is typically to power fans, so, maybe the motherboard needs the 24pin power connection instead of a 20pin connection from that power supply. Or you could have just missed securely plugging in the connections. -- |

The specs don't mention a 2 wire as such. Maybe a SATA power? One issue with systems that don't power up correctly is problems in the standby circuits. Or you could have capacitor problems. (google search for "bulging capacitors". You could also pull the power up connectors off the board and see if shorting the pins with a screwdriver will bring the system up. The power up switch hits the standby circuits on the M/B and those circuits then signal the P/S to come up. IIRC, it is the green wire going to 0 that brings it up. |

I also have a question regarding a PS wiring. Do the multi-rail have their cables marked as to which rail the wire is connected? It is conceivable to have "everything" connected to the same rail if the wires are not marked? |

I'm afraid it has been discontinued. Thanks for any help! David Most likely reason the Micro Center supply doesn't "work", is modern supplies are missing the -5V output. http://www.highpowersupply.com/produ...60302df.htm#sp The HPC-360-302 does have -5V. The usage of -5V was discontinued years ago (10+ years ???). Motherboards really should not be using it, but occasionally you run into an older system that still has that dependency. Such an old motherboard won't start, unless -5V is present. It is pretty hard to detect whether a motherboard needs it or not. Even if you took an ammeter, and measured current flow from the -5V pin on the main connector, the current draw could be so small as to be inconclusive. The motherboard won't be drawing gobs of power from that rail. If you look at the Micro Center supply, you'll find one pin is missing from the main connector. When the latest ATX standard removed -5V, they just removed the pin from the connector, so that there would be no connection to the motherboard on that pin. You can use that fact, or you can look at the label on the side of the supply, to see there is no mention of a current rating for -5V. You have two choices. Find an older supply, one with -5V on it. Or, if you have a friend who is acquainted with electronics, get the friend to hook up a 7905 regulator to the -12V, and make -5V from that. (You'll also need to install a pin in the "empty" location on the main connector, and connect your -5V circuit to that pin.) As long as the current draw from -5V is not too large, it might work. That alternative should only be contemplated if you really can't find an older supply. (Some day, finding a supply with -5V on it, is going to be impossible.) I think I have one computer in the house here, that needs -5V. And I'm not looking forward to finding another supply for it. (Power supply specs, oldest to newest. The first spec is for a supply that still has -5V. Compare that, to the other two specs.) http://web.archive.org/web/200304240...12V_PS_1_1.pdf http://www.formfactors.org/developer...X12V_1_3dg.pdf http://www.formfactors.org/developer...public_br2.pdf This is an example of a supply that claims to have some -5V output. This is not particularly balanced with respect to older motherboards. Some of the older ones, have more load on 3.3V and/or 5V, and the 12V might only need 15 amps or a bit more. This one has a lot of 12V capacity (good for modern systems, where the processor uses the 12V rail, as well as PCI Express video cards). But the 3.3V and 5V could use more amperes, to help older systems. (I have a system here, that needs 25 amps from +5V, an old S462 Athlon system) http://www.newegg.com/Product/Produc...82E16817338022 Sorry I can't find anything better than that. You may have to visit a smaller retailer, search around some surplus place, to find the right kind of supply. I have no idea where this company is located, what their reputation is, but at least the basic power numbers look good. http://www.mypccase.com/46foramdduat.html (This page has a few pictures of the ZIPPY HP2-6460P-SATA version.) http://www.newegg.com/Product/Produc...82E16817103707 (This page claims to have one unit in stock.) http://www.amazon.com/Zippy-HP2-6460...71387&sr =8-1 (This page has connector details. You would connect the 2x2 ATX12V to your system, and leave the 2x4 12V connector disconnected. This supply is also capable of powering dual Xeon systems with the eight pin power connector for the processors.) http://www.btostech.com/store/pc/HP2...ply-56p124.htm Good luck, Paul |
