I'm making my first attempt at building a PC and I've come across a problem. I installed my power supply (Thermaltake Toughpower 700W) in to the case (Thermaltake Tsunami Dream). Then I placed the CPU with the heatsink and fan on to the motherboard (ASUS A8N- SLI Premium) and mounted that in the case. I also added a video card (EVGA e-GeForce 7900 GS). As far as I know I have all the power connectors in the right places but when I plugged it in to see if the power supply and all the fans worked I got nothing. Not even the fan in the power supply started. I tried using different power sockets and different power cords but no luck. Anyone have any idea what the problem(s) would be and/or solution(s)? Thanks in advance for any help.
That thought came me as well. This is the second PSU that I have bought as the first one didn't fire up either. One question though, what exactly does rma mean? Remember, this is my first time.
RMA=return materials authorization, basically you call the company and they get your name and a description of the problem. Then they give you an RMA number that is a reference to your problems in any phone calls or emails you may make. If you mail anything back, make an extra line in the address and call the rma# to their attention.
make sure the front panel connectors for the power and reset switch are hooked up right. when i built my first computer a while ago i had the same problem and it wouldn't power on. i just had those connectors messed up. look at the manual for your mother board and double check you put them in the right place.
Ok. With the advice I got here I have made some progress since I first posted. It turns out that the reason I saw getting no power was that I connected the panel wires to the wrong part of the motherboard. After pouring over my MB manual I was able to find the right jumpers pins to put them in. I how have power to the MB, the CPU fan works and the switches and LED's on the front panel working. The only thing that I need to do now (until the next problem pops up!) is the case fans. Do I connect them to one of the power leads from the PSU since the fans have Molex connectors? Also, Can I connect the front fan with the back fan and then connect the power lead or do I have to use a selerate lead for each fan? I want to get the case fans working before testing for the POST and adding any more components. These may sound like really dumb question but this is my first attempt at this and it is a learning process for me. Again, thanks for any and all input!
if the fan has a built in power splitter then you can connect a few together and everything should work fine. i wouldnt try that with 5 or 6 fans but 2 or 3 you can hook them together and use a single plug from the psu.
If they have small 3 pin connectors that will fit the motherboard, use them as you may be able to control their speed that way. If not, stick them together in the power supply. There's no harm in running several fans off the same large molex connector, but using 3-pins, one fan per slot, always.
