I put everything together last night and all went well from what I thought. I went to turn it on and I hear a click from the Power Supply and get nothing. The green light on the Motherboard is on so I know it at least has some power. So, I proceed trying a few different outlets because the house I'm in is pretty old. Still nothing more than a click.
Next, my roommate suggested unplugging the video card from power to see if it's trying to draw too much from the supply. Sure enough it kicks on and everything is perfectly fine without the video card on power. The video card fan is running so it at least appears the the card is good. Now the Power supply has two PCIE connectors one is a 6+2 and the other is a 6. I try both of them to no avail. Finally, I try the 6 pin PCI-E to 4 pin Peripheral adapter the video card came with. This also does not work at all.
I'm just a little perplexed as to how this is possible. From Newegg the ratings on the Power Supply are as follows:
The video card recommends a 450W supply capable of delivering 75W through PCI-E. I can't say I know which line the PCI-E power is actually pulling power from but all the 12v rails are capable of delivering way more than the recommended 75W. This worries me because I had planned on doing some overclocking and if I'm already having a power problem this doesn't really bode well for me.
Did I get a dud for a power supply or am I trying to use too much power? Sadly I'm outside the 30 day return on Newegg so I'm at Antec's mercy with this power supply. If anyone has any thoughts I would really love to hear them. I plan on doing some more troubleshooting once I get home but I wanted to see if I could get anymore help from more experienced people. This is only my 3rd computer build.
I'm confused, how do you know your computer is working after you unplug the GPU? You can't tell if the system is posting without seeing something on the monitor and that MOBO doesn't have integrated video.
Sorry, I guess I shouldn't have said it boots without the video card being plugged in. I should have just said I get power to all other devices.
I looked through the thread you linked a little before posting. Most of those I can verify are correct right now. Although I will try the following when I get home
6. Have you tried booting with just one stick of RAM installed?
20. Have you tried resetting the CMOS? The motherboard manual will have instructions for your particular board.
I'm also going to try to convince my roommate to let me steal his video card from his desktop to see if I can get some POST information without my current video card in. I'll post back with the results later. Thanks.
After doing quite a bit of troubleshooting in my machine it seemed like the video card was the problem. I brought the card over to a friends house and tried it out in his already working machine. Sure enough his machine wouldn't boot with it either and he has a 1000w Antec PSU. I submitted the RMA request for the card and I'll try again once the new one gets here. Thanks again for the help. Hopefully I won't have anymore problems with a new video card.
