So for some reason my 250 watt power supply went kaputz. So I happened to have another one, 750 watts and I installed that one yesterday. All the lights are running, all the fans are going, but when I plug in the monitor it says no signal. Also when I I plug in the mouse int he back, it doesn't get power, though that could be because the thing isn't starting up correctly. I think I might have not plugged something in correctly. This is my first time installing a power supply from scratch (though when I originally built the system I did do all the plugging in.)

Here is a photo of the insides.

Also here is a video:

Specs for the Computer are
9800GTX+ (if I remember correctly)
3.2 Pentium dual core
2 gigs of Ram
GA-EP45-UD3L motherboard

Still pretty new at building my own computer and stuff, so I don't exactly know if I plugged everything. As the video shows, the phase LEDS are on, but I don't really know what that means.

Sorry the image is so big. I didn't realize it was going to do that. I tried editing it out, but it won't let me for some reason.

Why all the adapters ?
I see what looks like a 4 pin CPU connector hanging out on the drive bays, also a 6+2 pcie connector there.

Well the power supply only has one plug, and the card requires two. It can use only one plug but it runs funny if you don't.

Okay so I think I may know what the problem is. Forgive my ignorance but what is this?

Floppy drive power connector.
Did you plug in the 4 pin cpu connector yet ?
What's the make and model of the power supply ?

Funny you should point out the cpu connector because after posting the picture I realized i hadn't and had just finished doing that.

Now no lights come on at all. Power supply is an AK series Sata ATX power supply, 750 w. Made by apower

Personally I'd go buy a new power supply, one that cost's more than $34

yeah, except the problem isn't the power supply anymore, because I am getting power to the thing. It may be cheap and it may die on me soon, but for now, its working. The problem is that I haven't plugged something in right

Edit: Fixed it, thanks for the help!
