More Wake Up Requirements

August 16th, 2007

I'm researching the D945GCCR intel motherboard, and the manual says this:

For LAN wake capabilities, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing LAN wake capabilities can damage the power supply.

I just did a search on this subject: "+5 V standby current power supply", but actually a better search term is "5VSB":

ATX Power Supply Power-On Switch - this page is actually very helpful! It explains how the power on switch works.

Finally found the wikipedia page on power supplies, which had these helpful tables:

24-pin ATX power supply connector (20-pin omits the last 4: 11, 12, 23 and 24)

Also found this interesting but unrelated page:
