First of all...so sorry about asking in this thread but thought it would be the best place where people would know.
I noticed an interesting distinction between the A2 and A2 Mega in regard to the power connectors the blades use and wanted to confirm with others.
The regular A2 (the one Emdje's old image works with) appears to have an Eight-Pin +12 V CPU Power Connectors on the blades. This means that +12v is on the top or clip side.
Example:
I realized this from the picture earlier in this thread:
Can someone confirm? I think it is fairly obvious but wanted to make sure. If this is the case then a standard PCI-E connector will not work as that has the +12 V on the bottom or opposite the clip side:
This is different than the A2 Mega. The A2 Mega comes with standard PCI-E connectors on the blades. I found it strange that the power supply provided with my A2 Mega had exactly six Eight-Pin +12 V CPU Power Connectors with cable lengths perfectly spaced for the location of the blades but were FORCE in to fit the PCI-E connector....now it makes sense. The power supply was build for the original A2 and they forced it to work with the A2 Mega.
Here is a picture of an A2 Mega with PCI-E connectors and the Eight-Pin +12 V CPU Power cables forced into them:
I guess it is important to know that +12 V on the original A2 (blue PCB) is on the top of the connector but +12 V on the A2 Mega (green PCB) is on the bottom? What would happen if they were reversed (if someone plugged in a PCI-E cable into the A2)? You can't physically plug in an 8-pin PCI-E cable into an Eight-Pin +12 V CPU Power Connector but a 6-pin PCI-E cable would fit.
I realized all this while working on replacing the PS in my A2....decided to delay until I get my voltmeter from work to verify.
