Booster X5 problem?

[TzunamiOSX]

Yesterday I tested my new Booster X5 with some of my old GPUs. All is working very well, but the ATI 5770 behaved a little bit strangely. The fan of the 5770 ist spinning slowly when the computer is turned off. A voltmeter also shows no voltage at the "PCI-out" of the Booster X5. Why the fan rotates?

Does anyone have the same phenomenon?

I haven't seen that at all, no. Is the BoosterX 5 daisy-chained to the Mac Pro's power supply correctly?

I think there is nothing I can do wrong^^
-220V Cable (Europe) to socket
-5V/12V CD/DVD connector to the 5V/12V port of the X5

Perhaps this is a MP 3,1 thing. I will test it tomorrow in my MP 5,1.

Problem found!

Voltmeter was set to AC, Booster have always 12V on GPU out

AHHHH, Im going crazy! Same problem on second Booster

Is it normal when I have always 12 V on the GPU-Power Output? The X5 is only connected to the AC Power and there is no Molex connected.

Only connecting the mainpower and I get 12V on GPU-Out. Does anyone have a Voltmeter, a Booster X5 and can measure his Booster, please.

If this is normal, what is the funktion of the Molex?
