I just finished building my first pc, or so I thought. I went to turn it on, but nothing happens. The best that I get is that the lights on the keyboard flicker once when I flip the power switch. I have checked and re-checked my cabling, and I don't think that I messed that up. Any thoughts?

One thin I just noticed was that most of these pieces require 500 W power, but mine is only 530. Could that be it?

No you should be fien with yout 530w power supply. I would make sure to recheck your connections fromt he power supply to the mobo. Is this your first pc build? Do you have another power supply that you can use to test with?

I know you said your keyboard had a quicl flash of activity but what about any other lights that you may have? In the worst case scenario, do you see any arc marks or brown marks on the mobo?

yes, this is my first build. I've checked all my connections, and I"m pretty sure I got it all. The only thing I don't have plugged in are most of the fans, because they have a different connection than the mobo or power supply offers, and a small connection labeled AC'97.

Ok do you have the fan that comes with the heatsink on the processor plugged in? If you do. Then when you power up the PC do you see and or hear either the power supply fan or CPU fan kick on? You should at a minimum see the fan blades try to turn even for just a quick second. If you do not see any of this, then I would definately test the power supply. If the PS is good then I would start looking for small arc marks or brown spots on the mobo. Do a visual check to tsee if anything is fried just in case.

Is the power supply new or a re used one from a older computer?

It's a new power supply. Absolutely nothing happens when I push the power button. As far as I know, there are no scorch marks. As for now, I'm going to just unplug everything and try re-cabling and see if that works.

RaidMax is known for being an excessively mediocre brand.

The following is cut and pasted from an earlier post:
[i]If you have a multimeter, you can do a rough checkout of a PSU using the "paper clip trick". You plug the bare PSU into the wall. Insert a paper clip into the green wire pin and one of the black wire pins beside it. That's how the case power switch works. It applies a ground to the green wire. Turn on the PSU and the fan should spin up. If it doesn't, the PSU is dead.

If you have a multimeter, you can check all the outputs. Yellow wires should be 12 volts, red 5 volts, orange 3.3 volts, blue wire -12 volts, purple wire is the 5 volt standby. Measure to the PSU case or a black wire.

The gray wire is really important. It sends a control signal called something like "PowerOK" from the PSU to the motherboard. It should go from 0 volts to about 5 volts within a half second of pressing the case power switch. If you do not have this signal, your computer will not boot. The tolerances should be +/- 5%. If not, the PSU is bad.

Unfortunately (yes, there's a "gotcha" ), passing all the above does not mean that the PSU is good. It's not being tested under any kind of load. But if the fan doesn't turn on, the PSU is dead.

I had a similar problem after installing a new 4770 graphics card. Do you have another graphics card you can swap out? If that doesn't help then it is definitely the power supply.

Thanks for the help, I got it up and running. What I missed was the miniscule +and- signs on the power switch cable. Curiously enough, the core I have has the potential to unlock two more cores. Any thoughts on how that works?

So you didn't turn on the power switch on your power supply?

Reply to TheOnion

no i did. It was the wire to the power switch. Like I said, I didn't notice the tiny positive and negative signs on it.
