TX750W problem


Recommended Posts

I think the power supply isn't providing enough power for my system. I wonder if its defective or not because my system is really an older system with average components.


The problem is my computer start and stop a few times before it actually boot. I can see all my fans spin but the one from the CPU start after a good 10 sec. (I had a G-Power fan and replaced it with the fan coming with my CPU to make sure it wasn't a fan problem but it does the same thing).


It might be the normal process as if I unplug a few 90mm fans the system do the same thing but do not stop and boot properly.


I have 4x 90mm fans in my system.


I have listed all my computer specs in my profile.


Any recommendation would be welcome.

Make sure you have the latest BIOS for the motherboard and load setup defaults. If you still have the same problems there is a few things that could be causing it. Defective PSU, problem with the motherboard/BIOS, or any component that might be causing a short or ground. If possible I would test the PSU in a different system and see if you can duplicate the same issues, if so, Request an RMA.


If you can't test in a different system then I would test your current system in a barebones configuration. Disconnect every device in the system which is not necessary for booting up into the BIOS and see if there is any change. If there is a change, then reconnect each device one at a time until you can figure out where the problem lies.
