Question about LogiSys Computers & Internet
I am not sure if it is the power supply itself as it is brand new, and i do not believe that it is an issue with the button. I have checked and double checked my pins and connectors. motherboard is an asrock, and its clean. Have not attempted to "jump start". Will soon. turned on a couple of times, then nothing. ftp://asrock.cn/manual/A780GMH128M.pdf that is the motherboard and manual so i am pretty certain that i am doing it correctly so far. previous power supply had same problem. 0 power on start up.

Hi ford, the most common case colored wires used for negative - is white. The colors blue, red, green are usually positive +. The internal speaker though it uses a 4 pin connector only plugs onto the 2 end pins. Black is connected to negative - pin & red is connected to + positive pin. (Depending on the MB model).
All these case LED's use 5volts DC. If you make a boo-boo, don't freak out. You can usually shut down the system & turn the connector 180 & re-connect it with out hurting the board. Suggest you connect 1 at a time & check in-between each.
Still having trouble, include the name & model number of the MB.

Is your new SUP has the same specs with the old SUP? like voltage output, WATTS etc....
Usually motherboards have a led light in it that will light up when its connected on SUP.
regarding the wire placements for power and led connectors, you can view it in your users manual.

It is more than likely that when your old power supply died a death, it damaged some components on the motherboard. Replace the Motherboard and chip, and you should be back in business. You can pick up some good value bundles to save money on buying the parts seperately. The power supply working again after turning off and on, is because there is a little trip in the power supply that triggers when it detects a fault. Powering down resets that trip allowing it to try and work again.

It never hurts to have a larger power supply, yes it have use 100watts more in a hour. But you should have better reliability with the 450W.

It's possible that while booting your motherboard without the 12V power connected you physically damaged some components which eventually lead to the chip burning up. However, it is quite possible that this motherboard was defective as Foxconn has discontinued it. I would recommend RMA'ing (return merchandise authorization) the motherboard back to Foxconn. While no one wants to wait for shipping it is probably your best bet. Even if you order the chip that has been damaged, and can properly solder it back in place, there will most likely be other physical damage that is not visible to the eye. I would recommend another motherboard, and Foxconn has quality mobo's for around $50. Try visiting www.newegg.com. Hope this helps :)
