whoa woodchip, great link. will take me a while to read. for those also interested in this post,
"It had to happen sooner or later. A new ATX standard for power supply units is available and is set to replace the current ATX 1.3 standard. It's called ATX12V 2.0.
An adapter is required to be able to use the new 24-pin plug in motherboards that have the current 20-pin connector. Most power supply unit manufacturers include one with their new PSUs, because 20-pin connectors are still being used on most motherboards. A 20-pin power-supply cable also fits into the adapter, making it possible to use an old-style power supply unit with a motherboard that has the new 24-pin connector. "
so you can use the new standard. any recommendations for PSU's welcome. thanks folks
