Antec truecontrol 550

Hi,

I know I can Vmod it through the sense wires but I was wondering if there isn't a more simple way to do this since the control bay uses VR's too. Isn't there a way to replace the VR's on the control bay? If so, howmuch ohm should the replacing VR's be?

thanks in advance,

I have never looked at the control panel...so not sure how tuff it is to replace them.

If possible, you need to replace with a higher value VR. I would say 2 times the resistance would work nicely.

I might give it a try then.

thx :up:

I have a problem, I tried measuring the resistance on those little pots but my multimeter isn't accurate enough.

I placed it on lowest setting (200) but readings were fluctuating between 0.3-0.4.

Now what do I do? Should I trace back the contact points to the connector and stick a fixed resistor in there to see what gives? If so, howmuch ohm should it be? I would think 0.5 ohm would do the trick if such a value exists (I'm not very experienced :)).

If I only connect the 3.3V line, the rest should still work only below spec as is the case when you don't connect the control pannel right?

I dont exactlly follow what you are saying.

If you are trying to measure the resistance of the individual pots that are mounted on the front panel, you have to disconnect the front panel from the power supply.

If you are then getting a low reading, that simply means you have the pots turned down all the way as far as they will go. Simply turn the pots and that will increase the resistance.

argh right, I should have know that :brick:
I had the same problem when I was trying to set the VR's for my NF7 mods :rolleyes:

I didn't unhook the control pannel from the psu eather.

thx for the advice :up:

changing the pots on the control pane will not do anything.

because when you have them maxed, they are 0 Ohms. increasing resistance decreases votlage.

so, no go :(

Not so sure I agree with you on this Stang.

If you switch out the internal pots on the PCP&C units to pots with higher resistance, you can increase the voltage.

i've looked at the circuitry on my TC550..

there's no way you're getting more volts by switching out the potentiometers

[kristos]

well, it doesn't work, just as Stang_Man said.
tested it. I got the exact same values when the new pot was turnend completely to the right.
guess I'll have to do it the old fashion way :)

nways, thx for your input :)

thanks for verifying kristos!:)
