ATX when?
When did Compaq begin using ATX motherboards? I have a broken Gateway
(with FlexATX MB and ATX PS) computer, and I think the power supply is what's gone bad. I'm hoping to use the power supply from a Compaq that is about 6 years old. I haven't seen the old Compaq yet, and I don't know if it's worth the trouble to go and get it. I don't even know the model number at this point, just its age. OTOH, I'm not sure it's the PS that is bad in the Gateway, and don't particularly want to buy a new one at $50. So, is there a chance that the PS from the Compaq will work? Thanks. |

A chance, yes. 5-6 years ago is about when Compaq began dropping the
proprietary PSs and switched over to standard ATX supplies. HH "Al" wrote in message . .. When did Compaq begin using ATX motherboards?

That would seem like a dangerous thing to encounter, since it could send the wrong voltages to the wrong places. |

For a while, during the Pentium 2/3 epoch, Dell used a standard-looking ATX
connector with different voltages on the wires. Plugging a Dell pseudo-ATX power supply into an ATX board, or vice versa, is a sure recipe for burning out a board. AFAIK, Compaq did not play the same stupid game that Dell did. But just to be doubly sure, compare the wire leads from the power supply to the ATX-looking connector. The colors indicate the voltage and polarity. There is no standard for the colors, but if the groupings of colors are the same between the two connectors, you are probably OK using a generic ATX power supply. Power supplies with true and real ATX connectors come in several sizes, depending on the computer chassis where used. But the connectors are the same. ....

In article , ben_myers_spam_me_not @

Power supplies with true and real ATX connectors come in several sizes, depending on the computer chassis where used. But the connectors are the same. Thanks for the tip, Ben. I pulled a working ATX PSU from an old Presario and compared the colors. In this case, they were in fact the same. (There were some minor differences - the Gateway had one wire [white] missing; and at one pin, the Compaq has two wires into one pin.) The end result was the same behavior, though; so I guess it's not a PS problem. |
