TX750M Power-on Problem


HoovaDevil

Recommended Posts

Hi. I bought a TX750M from Ebay a while back and it has been fine running an ASUS Sabertooth 990FX, AMD FX-8350, Evga GTX-580 3GB, DVD-RW and a single SSD using the fixed cables.

 

However I've just installed 2x WD Reds and find that I cannot power-up when a device is connected via a modular cable. The MB LEDs/CPU fan are active for a second or so but that's it. Even if I disconnect all the devices from the fixed cable the result is the same with only a single DVD-RW attached to the modular cable, so it's not down to overloading. I can also add more devices to the fixed cable of 4-pin molex without a problem.

 

Any ideas?

 

*** Additional Info ***

 

As an answer might prove difficult I'll just get a couple of adaptors and connect the SATA devices via the 4-pin molex connectors.

Sounds like someone sold you the PSU with the wrong cables. If the pin-out is incorrect, whatever you plug into the cable is going to short out the PSU, which will prevent it from powering on.

Hi jonnyguru. Thanks for responding.

 

I had thought as much but cannot confirm it as only the blue power cables are marked as HX/TX.

 

It may be that the seller had more than one type of PSU or mixed-up the old with the new. I'll attempt to contact them.

 

Failing any resolution with them I assume it's possible to rewire them providing the contacts can be unlatched. The question then is what is the correct positions for them.

 

I have a multimeter to verify what they are now so it shouldn't be difficult to work out.

 

Thanks for help.
