Solved W5243 won't boot. no signal to screen.

December 25, 2012 at 15:14:02
Specs: Windows Vista, am2/2 x 1 gb ddr2
Emachines W5243 power supply. The motherboard power connector has 24 pins, but the power supply plug only has 20. Is this supposed to work? Im helping a guy out with this one. He has had it to Best-buy and it still doesn't work. My Emachines has a 24 pin power plug and this one has only 20 coming off the psu. I think it has windows vista. I tried the cpu in my comp and it worked. cpuz said it is am2. i don't know whats wrong with it. i even replaced the motherboard and still nothing.

Is that the original power supply? If the pins are mismatched, how can you connect it? Do you have a volt meter to check it?

✔ Best Answer
You already know what the problem is, why are you swapping the board, CPU, etc. The extra 4-pins on the 24-pin ATX connector are to supply power to the PCIe slots. Get the proper type power supply & do NOT buy it from BestBuy.

it will connect to the lower 20 pins, leaving the top 4 exposed.

Yes, I know, but if you have anything connected to the PCIe slots (video card for example), you will need a PSU with a 24-pin plug.

BTW, Bestec power supplies suck.

The customer bought it, not me. I was just trying to help him out by testing the parts 1 by 1 to narrow it down. I can't believe Bestbuy would put a piece of crap like that in his computer and expect it to work. The brand is L & C. Never even heard of them. No sata connectors at all on this one. All molex. They even replaced his hard drive and had to use an adaptor; sata to molex. I will tell him to order that power supply you suggested. And thanks. Merry Christmas to all.

I have a Seasonic X660 in the closet. Would i be able to hook it up externally to see if it works, or does it need to be installed in the frame to be grounded?

Ground it with some alligator clips. If it explodes, see you later alligator.
