Before you can understand exactly why I am so confused, you need to understand what I have been through in the last few days. First, I was having a problem with my computer after installing a new x700 pro; everytime I turned my computer on, the fan on the x700 pro, and my case fans, kicked in full speed, there was no picture, and the computer did not boot up. I would do a hard shutdown, and after going through this several times my computer would finally boot up normally. This problem lead to me starting a topic called "some problems with my new video card". One of the ideas thrown around in there was that my power supply was too small, so I decided I would get a larger power supply. And for this, I started a topic called "are all psu's the same size?". After this, I was ready to buy my new power supply, when I decided to do some tests.... I used an amp meter to find how much power my computer was using. In about 15 minutes of some intense gaming, the amp meter never went above 1.8 (avg was about 1.55 or so). If the computer uses 1.8 amps, (x115 volts) that means it consumes 207 watts of power at most. Assuming the psu is 70% efficient (doubt its that high, probably more like 65%), the total power output is still only 145 watts. If the psu is 80% efficient (yeah, right...) the output is only 165 watts, and I have a 305 watt power supply. This rules out my power supply. Any other theories as to what is causing this??

I haven't installed any other parts. The system is an unaltered (except the x700) three week old DELL 4700 series. I made sure everything was connected tightly... the card works perfectly if/when the system boots up properly.

The computer did have onboard graphics, and according to the BIOS, they are disabled.

The x700 does not have any cables... the power is supplied through the PCIe slot.

The monitor doesn't have any problems. The computer just doesnt boot up until the third or fourth try.

odd. I though most newer cards this day need there onw powercables from the PSU to make it run properly I looked at images and did not see any power connector:uhm:.
