Hi again, All,
I've gathered some additional information regarding the QuickSilver power supply, as opposed to the QuickSilver 2002 power supply. I have one of each system currently in hand—I can verify that an original QuickSilver has a power supply rated at 344 Watts, while a QuickSilver 2002 has a power supply rated at 355 Watts.
Details and snapshots of the labels as follows:
original QuickSilver power supply
Manufacturer: AcBel
Wattage: 344 W maximum
Manufacturer part number: API1PC12
Apple part number: 661-2514 (found via Google search; not printed on the label itself)
QuickSilver 2002 power supply
Manufacturer: Delta Electronics
Wattage: 355 W maximum
Manufacturer part number: DPS 340AB A Rev: 02
Apple part number: 614-0158 (apparently, not a standard 661- part number)
Looking at the two power supplies as they're installed, they appear to be identical in form factor and I see no reason why a 355 Watt model could not be installed into an original QuickSilver (or even in the Digital Audio and/or Gigabit Ethernet models, with the proper mounting bracket). As others have noted the MDD power supply appears to be rated at 360 Watts, this might mean there is a single, drop-in solution for those wanting to take a stab at running the OEM Radeon 9700 in
either QuickSilver model, and without having to modify your case in any way in order to cram a MDD power supply in there!
DISCLAIMER: Apple has been known to place differing (but compatible) parts into systems based on availability at the time of manufacture. While I have one of each model in hand and so have provided a photo of each, do NOT purchase a whole system unit without actually checking the power supply label to make sure it does, in fact, have the proper power supply you seek! And even so, we're still testing here and so any information I can provide should be considered anecdotal at best, and not "definitive".
I'll be in touch as soon as the OEM Radeon 9700 reaches me within the next week or so, and will provide further information at that time. Here's hoping!
