Why did the wires from my power supply to the motherboard melt

Hello,
i recently built a computer everything new except my hdd. in the specs for the mobo it says it needs a min. of 450w i have a 530w. the power supply has an led light also. at first when i tried to start the computer the fans and lights lit up for maybe a second thats with both atx connected. the 12 pin and the 4 pin. then i took the 4 pin out and it started up but wouldn't boot up. and there is a red switch on the back of the power supply that i think changes the output. because i can get the compter to turn on but the wires to the 4 pinstart smoking and i already melted some. then used electrical tape and taped them up. is the reason my wires are melting because i still don't have enough power?

Your mobo may need 450w, but your HDD needs some, and your CPU needs some, and your fans need their share.

The red switch on the back... It says 110 and 220. A standard outlet is 110, if you put it on 220 i'm not sure what would happen. Nothing good though.

My advise, dont build something unless you know what you're doing.

I had feeling that it had to do with the power so i went ahead and got a 630w hoping that will be enough. it comes in today. but i still have the fear that it may not be the problem. I still don't understand why the 12 pin is fine but the 4 pin or cpu power over heated and melted I've been looking for the specs. i think it's 600w so does that mean that the 630w still wont be enough?

Lesson from experience. Don't cheap on power supplies. Hopefully you didn't fry anything.

You should also list your full build so we have an idea of exactly how much power it would need.

yes it is a raidmax

my mobo is an extrme design M4A88TD-V Evo/usb3 i'll try to get links i'm a lil pressed for time right now. i have a PNY Verto GeForce 210 graphics card. CPU is AMD Phenom II X4 955 X4. 2X 2GB ADATA DDR3 1333 for RAM. 3 diff. Fans

You ALWAYS want to reinstall your OS on a new build unless you have no other choice. There are so many differences with drivers and what not, it's best to reinstall.

i have done that and vista which i have says there is no hdd in any SATA port and i assure you it is there. i just got realised in my manual it says that NTFS is not supported in DOS invironment could that be why it won't recognise it should i convert it to FAT32?

no bios doesn't either and i've tried IDE and AHCI

I don't think so your board is fairly current so there's no way it can't recognize a ntfs boot partition. Either you're doing something wrong or you're doing something wrong.

Set oyur sata drives to AHCI mode. And just boot with the HD and dvd drive, no extra ide drives if you had those connected. But as suggested I'm thinking you fried something as well.

Like I said, I know I cheaped on the power supply, and I think it was a few days later that ports on my board totally died. Exchanged the board, all was well. But just thinking that with wires melting=not good.
