OK so I've put together my desktop computer, Q6600 processor, 8800GTX vid card, 520HX power supply, 4GB RAM, Abit IP35V Motherboard, Thermaltake heat sink w/fan and hard drives and optical drive. I connected all power supplies and when I plug in and turn on the power supply the two red lights on the MOBO light up(showing its getting power and on) but when I turn the power button nothing happens, any ideas? The power supply fan doesnt turn on when I turn on the power supply, should the fan on the PS start right up? Also, on the power connector to the MOBO it has a blue and white wire and a positive post on the mother board, I assumed the white was the positive so I plugged the white side of the power switch into the positive post and the blue on the negative side. Any suggestions on what I can do to troubleshoot this?
I think you did not put Case Standoffs, and motherboard is touching case metal. When standoffs are not use, motherboard touches metal and this causes system to not turn on at all. Remove your motherboard, and check u added standoffs.
I have a couple wires that are not plugged into the MOBO because I couldnt find their connection on it. One is AC '97 and the other is 1394. Would those make a difference? I installed Brass standoffs (6) so that isnt the problem. I'm checking the power connections now, and to make things worse my original desktop just went down, so now I really have to ge this thing up and running!
Oh, and in the Antec Nine Hundred manual it refers to th Reset SW, Power LED, Power SW and HDD Led, all are installed OK except the Power SW, I cannot find this connector in the case. Maybe I am overlooking it, but its not with the other three which are on the same main cable.
Dont worry about the 1394 wire because mine is not connected to my motherboard either,Try switiching around your front panel led wire's.Your orange may go where your red go's and your red power wire may go where your orange one go's.I switched mine around and then mine powered up fine.Give it a shot!

I'm a little cautious about switching the power connections backwards, because in the Motherboard manual it states to be careful of which one you connect to the positive side, any idea if this could cause damage to the motherboard if switched or should I give it a try? Currently the white is on positive and dark blue on negative side.
Ok read the led wire's carefully and also the motherboard pins carefully and double check that again,it's really the only thing i can think of. I only said switch the colors before because my motherboard and led power wires match up differently but then again not everyone has the same motherboard and case.

Well I plugged in the main power to the motherboard, and only the CPU fan and switched the power cables around (so the blue is on the positive this time) and still get 2 red lights.
To answer about the power supply voltage on the rails, the manual says "Triple 12V rails provide independent reliable power to the CPU, video card and other components with a combined rating of 50A (40A on 520W) maximum. Advanced circuitry design that automatically enables power sharing between the triple 12V rails in an event of overload on any single 12V rail. Powerful +5V rail with 3A rating."
"Oh, and in the Antec Nine Hundred manual it refers to th Reset SW, Power LED, Power SW and HDD Led, all are installed OK except the Power SW, I cannot find this connector in the case. "
The Power SW connects the power button on your case to the mother board, if you don't do that, how is the power button supposed to work???
BTW, whether the red LED light up means something is wrong you should really read the manual of you motherboard, AFAIK there's no LED that can change it's color.
Funny thing about that, the manual really isnt much of a help with the LEDs.
The Abit IP35v manual I have only refers to two LED lights, one by the 12 pin plug in, (the VCC light) and states "this LED lights up when the power supply is connected with the power source". I do NOT have a light there at all when I turn on the power to the unit.
There is one other LED referred to (5VSB) states "This LED lights up when the power supply is connected to the power source" and mine is lighting up. There is another light on my MOBO, not depicted on the manual in the far right hand corner (nearest the processor) and it lights red, no reference to that LED in the manual though.
I tried to find an online manual for this MOBO, since the Antec 900 had more recent info on their online manual for the case, but cannot find one. Anyone know what this LED might mean that has an Abit motherboard?
The way I understand is that, the 5VSB lights up when you the power supply unit is connected and switched on, (red or green it depends on the type of the LED installed) the VCC should light up when the power button is turn on, if yours doesn't, that's not right. Don't know about the LED near the CPU, maybe your CPU fan isn't properly connected???
The non-lighting LEDs are difficult for me to see, they are very tiny, so all I can tell you is I've got 2 lighting up in the locations I mentioned. Is it possible it is a power supply issue, could the board still light up but no power getting to it somehow, I saw a post on Abit's forums where Corsairs have been having trouble posting. (link below)
Reason I ask is that the PSU fan isnt spinning when I turn it on and none of the CPU fans spin, even though they are plugged into the correct location on the MOBO.
