Default Possible Power supply problems?

Hi everyone. New to the forums, been reading quite a bit though.
I just built a new system with a carsair TX650 PSU, Asus P755d-EVO MB, Core i5, His 5770, WD black 500. I had the stock cooler on for a little while and just bought the zalman flex with a pair of coolermaster R4's. I have been unable to connect to the 4 pin fan connectors on my motherboard as the system will not turn on. The only way to connect to the 4 pin connectors is via the connectors from the PSU, I have been unsuccessful so far. If connected to the 3 pin connectors on the MB everything works fine, but I can only have 2 fans going. I have sent the question to Corsair as well, but I am wondering if I am missing something or if anyone else has had the same problem. My intel HSF works fine when connected to the four pin.
Thanks for any help and suggestions.

Edit: Wow I can't believe I didn't figure this answer out sooner. But all is well and the brain freeze is done.lol.

Try:
Connecting both Fans to a single Mobo Header using a splitter. (2 to 1)
Connect one Fan to one Mobo Header and the other Fan to another Mobo Header
Connect one Fan to one Mobo Header and the other Fan to your PSU

How many Fan Headers on that Board?

Heh... glad to hear that you resolved the issue, but no fair saying that you solved the problem without telling us what the solution was... Even if it seems like a no-brainer problem, chances are you aren't the first person to do it, and even better chances are that you won't be the last, so somebody might benefit from your recently gained wisdom.

The MB has two 4 pin connections and two 3 pin connections. The fans are all 3 pin connectors with the 4 pin adapter. Problem was that I was using the 3 pin adapters that came with the fans, so that I could plug them into the PSU. Once I got them hooked into the PSU i tried connecting the cable from the PSU into the 4 pin connection on the MB and the computer would not turn on. I dis connected it from the 4 pin and everything was working but I only had 2 fans(the ones connected to the 3 pin connectors). Couldn't figure out the problem for hte life of me. Went to sleep and woke up at 3am with the solution.lol. I just plugged the adapters that came with the fans into the PSU cable and did not try connecting that cable into the motherboard........and viola......works great. Not sure if that explains the situation well enough, I am not sure what the connections on the adapters are called, I think it is Molex from reading things but I am not really sure.
Thanks for the comments.
