Be careful - I still think it is the graphic card overheating! Rememeber - OS X GUI puts a lot more load on the graphic card than OS 9, and it can easily overheat in OS X and seemingly work fine in OS 9. Which graphic card do you have inside? Original Radeons were notorious for their active cooler going bad but I'd be surprised if it was still running after all these years...

You have two options: to replace the fan (I haven't had much luck finding the replacement) Or to replace the cooler (quite difficult as it is glued to the chip - however still possible if you are willing to fiddle with it). You may also check if someone has a extra dvnidia 2MX card from Cube or desktop lying around - these are drop-in replacement.

Yes, it can be oiled but you'll have to remove the cover over the spindle. However in my experience the fix is not very longlasting, at least with 3-in-1 oil.

The rectangular amplifier is a pseudo-external sound card that accepts it's input and power from the USB port. The drivers are built into Panther. If Panther is not seeing it, you may have a USB port issue. Did you happen to change from the port where the sound was working prior to the new install? The motherboard mounted USB ports do have a tendency to be touchy. First, determine if the problem is hardware or software. Try switching to another USB port (but not one of the ports on your keyboard, they don't offer enough power). Shutdown and reboot from cold to see if you get a boot chime. If you do, the problem is not hardware. Post back with your results.

Message-ID: Hi All. Has anyone out there ever replaced or attempted to replace a cube power supply? I'm not talking about replacing it with a stock PS off ebay, I mean replacing it with a similarly rated PS (i.e. similar current, voltage, wattage). Does anyone know approximately how many watts a cube consumes without running an apple monitor thru the video card? 224W (28V@8A) seems rather steep for a cube without a monitor. Looking at the original specs from apple it appears that this higher voltage and current was basically needed to run the crt monitor.

Message-ID: Hi all. If anyone is interested, here is what I've come up with so far. Given a worst case parallel circuit load configuration (that is, one in which each internal device within the cube forms a parallel circuit where the total current is divided in proportion to each devices conductance). Without the need to power a monitor thru the apple display connector on the video card should reduce the current requirement of the external power supply by about 4A (as noted in the cube specs)...assuming that the DC-to-DC converter board has load sensing (and any good, modern DC-to-DC board should). Hence, as long as one does not need, or ever will need, to use a monitor (apple display) that requires power from the video card (as is the case with me) one can write off 112W (28V x 4A) from the rating of a replacement supply. Thus, on the high end, one would probably need a 112W (224W - 112W) power supply to run the cube. Assuming that we would need to "fake out" the DC-to-DC board by keeping the input voltage at 28V, this translates into a power supply of 112W, 28V @ 4A at the high end. A low ball estimate might be gathered from the apple specs. That is, 5W for each USB port, 12W for firewire, probably 15-20W for disk and cdrom drives (I have lower power laptop drives in my cube), and probably 20-30W for the processor and MB. That's about 57-72W, which translates into a PS of 57W, 28V @ 2A or 72W, 28V @ 2.6A at the low end. Keeping in mind that the DC-to-DC board probably has load sensing and this figure would probably be very close to what is needed at a minimum, since all these devices don't run all at once, all the time. Since I don't want to spent alot of $$ to keep an aging machine alive, I think I'm going to try to rebuild the power supply with the low end estimate. A good candidate looks like the "Mean Well PS-65-27" switching PS from Jameco Electronics, (http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&pa=201946&productId=201946). It even appears that it will fit into the original apple PS enclosure. I'll keep you posted on any further progress I might have.

I assume that the dc-dc board handles all the loads, monitor included. It is definitely used to step down the 28V to other, more standard voltages (i.e. 5V, 12V) found within the computer. The voltage/current is supplied to the monitor via the video card, and the video card is powered from the system bus...I think. The dc-dc board just handles the MB/processor voltages and not the voltages on the system bus? Does anyone out there know for sure?

When I disassembled the power supply I noticed that there were three out bound wires connected to the internal board. One was a chassis ground, the other two were power and power ground. The interesting thing is that the power and power ground wires were later each split into two, forming the set of four outputs on the power plug. It looks like that funny four connector plug consists of two similar power and ground pairs. That is, they split the current while each having a potential of 28V. Maybe the pair power two different power buses within the cube.
