How many fans can be on one connector?

I have a four knob rehio bus that I use for my fans. I am going to have to do a better job of wiring them to the unit so I when I redo it, I am asking on one power connector how many fans can be run off that from the PSU before you start to overload that particular connector?

And how many fans should I limit per knob on the buss?

Thanks,

    I'm not sure, its a PC Power&cooling PSU rated for my board. 550w total I think...

    Here is my fan list.
    2-80mm CPUs (dual Xeons)
    3-80mm front intake fans
    2-hard drive bay fan units 3 small fans each
    1-80mm side cage fan
    1-120mm rear blow fan middle rear case
    1-80mm extra cooling fan hangs down from the case blows extra air in the CPUs area (called the Xeon cooling kit)
    1-PSU fan if you wan to cout it, not seperate tough blowing out the rear
    1-80mm fan located in the top rear blowing out to vent the top section of the box

    Hummm, I think thats it...
    So about 11 fans in all... This the reho bus as cranked it sounds like a wind tunnel...
    Set at full blow thoguh, the case temp never gets above 34C and the CPUs are lucky to get much beyond 42C under full load...

    I hope that helps.

    I was asking about how many watts per knob on your rheobus...I'd suspect that if you're running all that on one rheobus that you're overloading it a wee bit though.
    I'd say as a rule of thumb for normal 80mm fans that 4 per channel should be pretty close to the limit, for 120's 1 per channel and for 92's 2-3 per channel depending on the cfm/wattage.
    If you got a second rheobus and spread the fans out on them then you could do like fans on a knob I.E.; knob one-front fans, knob two-rear fans, knob three-cpu fan Ect. Ect.
