Modern G4 Cube PSU replacement?

All Guru,
I just have a question. I found a modern one, 24V 3A. I tested with multimeter found out that the polarity of all prongs are in the opposite with apple power mac g4 cube adapter as shown in figure. I put it in cube and it fit perfectly (without electrical).
My questions are as follows;
1. I can't use that adapter with cube unless I find the way to change its polarity to match exactly with cube's polarity or it will destroy my cube. Am I correct?
2. Suppose I can switch all polarity matching cube's original adapter, is it safe to use new adapter with cube? I noticed that even voltage is pretty close to 28V but it has only 3A while cube's adapter said 7.3A.
Thank you in advance.

Byrd,
Thank you very much for your kind.
I'm confusing since you said that my adapter (28V, 3A) would not enough to power the Cube. I won't use ADC monitor.
On the first page, Stormy had confirmed that 80Watt TDK PSU which has 28VDC, 2.86A, 80Watt, similar to mine, worked. Please explain more to me. I really appreciate all helps.
Thanks.
Can you show us the actual wiring you did here. I have a G4 power supply wire, which only has 3 cables: Red, Black, &White.
Never mind. I just pulled things apart and realized that the 2 pairs of V wires are combined inside.
Sorry I missed the post with your question. I don't remember the color code, but using the color code on the cable may not be the safest way to wire this up anyway. Best thing to do would be to use a multimeter to verify the continuity (ohms mode) shown in KMMs post above, then check the voltages after the wiring is complete before plugging it back into the Mac.
Just wanted to share what I did, found a 24v 150w led driver on Amazon for about $12. The fit was juuust right, making it somewhat easy to fit it in the original casing. Speaking of which, i simply pulled the sides off using only my fingers, pulling on one side until the clip on that side snapped. Put it back together using strong double sided tape. I’m happy with how it came out and took probably 20mins all in all.

Digging up this thread as I just got my very own Cube, but it came without any kind of PSU. No ACD either, so I'm not super concerned with hitting maximum deliverable power. For a seemingly stock 450mhz model (GPU is a Rage 128), what's my requirements? Would 24V 5A (with appropriate cord) do the job?
I’m using an ENP-240-24. You can dial it up to 28V.
I’m running an NVIDIA GPU and a bigger display and it seems to work. My VRM died as well, so I bought one of those update ones.
