CAse and PSU problems, any opinions or input much appreciated

[pdox]

Please could you offer your opinion on this one please. I have contacted my supplier who is happy to cover any swapping out that may be required

I have a Silverstone Temjin tj05 case. I noticed that the thermal controller that it has beeps randomly roughly every 5 minutes with the screen going black for a second. Initially I thought this was the thermal controller so I contacted the manufacturers directly (who are still involved if you wish to bounce anything off them, also very interested in outcome for their reference) they sent me a new thermal controller and it too does exactly the same thing. As a test, I wired the thermal controller to a cradle PSU to test, left it running for 9 hours and did not experience a single beep, proving the fault did not lie with the controllers.
My PSU is a brand new Enermax Noisetaker 480W, my PC runs absolutely fine with no errors at all by the way.
When bench-testing the controller with the cradle PSU, I flicked the power connection off for a split second and reconnected it, the screen goes black for a second and I get the familiar beep, basically the problem with the thermal controller beeping and screen fault is exactly replicated if the power is removed from the controller for a split second then reconnected. My logical thinking ( I hope???) leads me to think this problem is related to my power supply in some way.
My system is,

Asus A8n-sli mobo,
Athlon xp3700+ CPU
Radeon X850 xt pe graphics card.
1 x DVD writer
1 x DVD reader
1 x IDE HDD

Doubt the power consumption is over 480W but as a test for consumption and voltage drops, I connected the controller in on its own lead, dont know whether it is a coincidence but the beeping/resetting was much less, probably only 2 or 3 in three hours.

So... Your expert opinion on this if you please, Is there anything you can think of??

Your opinion is very much appreciated.

Known Facts:

1. Your PC with the Thermaltake Noisetaker 480W works perfectly.
2. Your Silvetstone thermal controller (2) works perfectly.
3. You were able to duplicate the random beep and blank screen with the cradle PSU and thermal controller by switching the Power on and off.


Based on the above I would think your Thermaltake is the culprit. But the switching effect, possibly due to timing and/or noise, distortion might well be within specs.

I do not think your system used more than the 480W rated. But that 480W might not be clean and flat frequency response.

One way to test this is to use a different PS. I do not know about Thermaltake PS or their characteristics but a Fortron or Enermax would be my choice.

Good luck,

Thanks for the reply, dont know what happened there, had a really dumb moment. The PSU is of course an Enermax one (Enermax noisetaker 480W) dont know where thermaltake came from!!!
