[G4] G4 Power Supply

[shopdog at mac.com]

All:

I have an AGP Graphics machine (model M7824LZ/B).

It's upgraded with a 1.2GHz Sonnet processor.  It has a Pioneer  
DVR-105 in it, and the original Zip drive.

Does anyone know how many internal hard drives it will support, power- 
wise?

It has 4 power ports on the power cable for hard drives, and I'm using  
2 of those for 2 hard drives on the original IDE bus.

Will the existing power supply support 4 more IDE drives?  I can get  
them in the chassis using 2 "Dual Drive Bracket"s, one each in drive  
bays 1 and 2, and I can get them to communicate with the motherboard  
via a PCI card (ACARD AEC-6280M) that has 2 IDE ports, but the only  
way to supply power to these four new drives is to use Y-adapters off  
the remaining 2 power ports.

However, I don't know if the existing power supply will support all of  
this.

If not, can I use a Quicksilver 344W power supply instead, in this  
machine?

Thanks for any advice anyone has...
