Power Supply Usage and Recommendation
Do not use non-Sparkle ATX power supplies. Only use Sparkle ATX Desktop Power
Supplies.
As the Desktop ATX supplies grew to meet the increased power for those
Motherboards, their minimum loading requirements also grew. When you try to run a
mobile platform on it, it may not load the 5.0V rail enough to meet the minimum
loading requirements for it to maintain regulation.
Recommended power 20-pin ATX power supplies include:
Sparkle Model No. FSP300-60BTVS meets this requirement and is an ATX12V 1.1
Spec (note that this part may be End Of Life)
These 20-pin ATX power supplies may also work if you can't find the above model
number (lower power supplies are probably better):
Sparkle (SPI) FSP250-60BT, FSB300-60BT, FSB300-60BTV, FSP350, FSP400-
60GN (these supplies work in the lab, although are not checked against spec)
DO NOT use Delta or PowerMan ATX Supplies. You may experience the following
symptoms when using a non-Sparkle supply.
