I may be missing something.
If so, please help me understand.

According to the label on the HP DPS-1200FB, they are rated at 800W for 110v to 120v input.
To get 1200W, you need a 220v AC input.

100v AC / 9.4A = 12v @ 66A max (800W)
110v AC / 9.9A = 12v @ 75A max (900W)
220v AC / 7.8A = 12v @ 100A max (1200W)

The iCharger 308 duo is rated at 1300W charging using both channels (I just bought one)

I have not listened to the podcast for the conversion, but I will assume it places the two HP DPS-1200FB in series to raise the voltage to 24v. But, they still only deliver 900W.

At 110v, a pair will use almost 20A AC and only deliver 900W.

The pair will put out about 1800 watts.
24volts times 75 amps=1800watts.

Stupid people have no idea how stupid they are!!!

Yep - I should have remembered my math.

I did the calculations back when I build my Dell Power Edge 2950 power supplies.
With 110v input, they are rated at 750W (12v / 62A) each.
I have 3 in series (36v @ 62A).
That gives me about 2250W output.

Hello all! Ive had an issue with floating the power supply. The first one I drilled through and killed the PS. I bought a new one and instead I 3D printed some standoffs that were glued to the bottom of the case where the metal threads used to be.

Now after putting the case back together, my voltage between the + and - terminals fluctuates between 10.5v and 13.8v. When doing a continuity test, Ill get varying readings between 1v to 3v.

All three standoffs were removed and replaced, but I have no idea whats causing this to still be slightly grounded? Any help would be appreciated!
