Comment: I am replacing my power supply with a BFG 650Watt supply and I have reconnect (seemingly) everything but the power wont work. I connect the cord, flip the switch on the back, and my blue lights come on (I have an alienware and it has blue lights in the front, so if these lights come on the power supply must be working) but the power switch is useless. Does anyone have any ideas of why my power switch can't turn on the computer.

Reply: (edit)Is it possible I have too much connected to one rail? I have my video card on one of the 4 pin white plugs and on the other one (my power supply has 2 12 volt leads) I have everything else (2 hard drives, floppy, 2 cd roms) with tons of splitters? Am I splitting it too much? What is going on?

Reply: (edit)You need to check all the connections of your PSU AND make sure all your components are seated correctly and all signal cables (IDE, SATA, FDD) are properly connected.

Reply: (edit)The problem is this new power supply has SATA cords and SLI cords, while my old power supply used mostly those 4 pin white connectors (and some small white connectors). This means that I had to split the crap out of everything and even disconnect a fan because I didn't have enough ports to plug it in. (Don't worry, the fan is a case fan that pulls in air, not a crucial fan)

Reply: (edit)When you replace a PSU in a computer, particularly one that has many components, it is wise to connect components to the new PSU as you disconnect them from the old PSU to ensure that ALL components get powered up by the new PSU. The process requires care and finess. It is very easy to dislodge cards and cables as you remove the old connections to components and the MOBO and make new connections. It is very likely that you have dislodged a card or cable AND/OR you have failed to connect the components correctly to the new PSU. If you have followed my suggestion in #2 above and still can't boot into your OS, I'd suggest you start at ground zero. Remove all your connections from the PSU, the MOBO, and the components. Connect the MOBO to the PSU. Then reseat the RAM and any cards on the MOBO. Now connect all signal cables from the MOBO to the components. Finally, make all the power connections from the PSU to the different components.

Reply: (edit)I checked the motherboard SK8N manual and I can't seem to figure out which wire for the power switch is the ground and which the power. If I get it wrong will it cause damage?

Reply: (edit)I tried it both ways and it just wont turn on. The stupid cable seems connected. Is there any other reason the motherboard power light is green but the power button doesn't work?

Reply: (edit)Here's the list of available plugs on your BFG 650W: 1 - 20+4 pin main ATX
2 - 4-pin ATV12V (CPU/motherboard)
4 - SATA
6 - 4-pin molex (for IDE HDD/optical)
2 - floppy
2 - PCI-E http://www.tigerdirect.ca/applicati... Seems to me that should be enough to cover everything. The PSU has two +12v rails of 20A each. One of those rails is dedicated to the CPU/motherboard thru the 4-pin ATX12V plug(s). Do you have it connected to the board, just above the 20-pin ATX connector? http://www.asus.com.tw/products.asp... I don't understand why you're asking about the power switch wiring...didn't the switch work before? When changing the PSU, there should have been no reason to unplug the case wiring from the board. Or am I misunderstanding what you mean in responses 6 & 7?

Reply: (edit)I accidentally pulled out the switch I guess (I must have), I do have the 20 pin thing connected and the four pin thing below it (or above it whatever), how do I dedicate a rail to the GPU? Also, I have a lot of case fans, and they were plugged in using the small 3 pin connector---->white 4 pin molox adapter. Should I change the way the fans connect?

Reply: (edit)Actually I just noticed something. When I press power the HDD light flashes for split second then does nothing. Maybe it is overloading.

Reply: (edit)You have more than enough power. IMO, a 650W PSU is overkill for your system. Fans use very little power, so I highly doubt that's your problem. And one of the +12v rails being dedicated to the CPU is automatic...you don't have to do anything other than connect the square 4-pin plug to the board. Maybe the PSU is defective? What was wrong with your old one? Why did you upgrade in the 1st place?

Reply: (edit)Hello,
Many times the wrong 4pin square is connected to the wrong 4square connections. There is a chance of self shut down or a blown fuse on the inside of the PS. If you are lucky the fuse will save your Mobo. The internal fuse will go off with a bang if you connect the wrong 4 square. Connect the 4 square connector with the latch to the connection on the motherboard that has the mating hasp on it's 4square.
