PSU problem?

[Doomer3003]

Hello everyone.
If i'm not in the right category for this post, pardon me, and feel free to move it.

First of all, I bought my build some weeks ago.

My build consist of:

Power Supply: http://www.directcanada.com/products/?sku=10370AC6497&vpn=TP-750&manufacture=ANTEC

Processor: http://www.directcanada.com/products/?sku=12200BD1527&vpn=BX80623I52500K&manufacture=INTEL

Motherboard: http://www.directcanada.com/products/?sku=16950BD2247&vpn=Z68%20Extreme3%20Gen3&manufacture=OTHERS

Video card: http://www.directcanada.com/products/?sku=16950BD9420&vpn=N560GTX-Ti%20Twin%20Frozr%20II%202GD5/OC&manufacture=OTHERS

Heatsink: http://www.directcanada.com/products/?sku=11130AC0554&vpn=RR-212E-20PK-R2&manufacture=COOLERMASTER

Hard drive: http://www.directcanada.com/products/?sku=16950AC0275&vpn=ST500DM002&manufacture=Others

Memory: http://www.directcanada.com/products/?sku=15380BD5798&vpn=F3-12800CL9D-8GBRL&manufacture=G.SKILL

DVD-Writer: http://www.directcanada.com/products/?sku=10530DR5213&vpn=DRW-24B1ST%20Bulk&manufacture=ASUS

Case: http://www.newegg.ca/Product/Product.aspx?Item=N82E16811147107


After looking at lots of videos on the internet, I took 5-6 hours of my time, doing very carefully my computer.
At first, the test build I made outside the case worked perfectly.
But when I putted everything inside the box, plugged everything, the power wouldn't turn on.
Seems like the power-supply was dead.

I ordered another one, and I shipped that one back.
Today, I received that power-supply. I plugged only the 20+4 pins in the motherboard, and everything was fine.
After that, I plugged everything in my computer (fans, hdd, video card, etc). I turned on the computer, and everything worked perfectly!

So I looked for my Windows 7 CD, I putted it in the dvd-burner, turned back to do something quick, and when I looked back at my computer, it was turned off. I pressed the power button, and nothing happened.

Sometimes, when I press the power button, the fans would work for maybe half a second and then dead nothing.

So I'd like to know, if it is possible that i'm unlucky enough to get 2 dead power-supply in a row, or if maybe something else is going wrong in my computer, or if I did something wrong, or if something in my build is incompatible or something..

Thanks in advance, and sorry about the quality of my english, i speak french most of the time.

i think the problem is in the case connectors and the power buttons of the case

the psu should be fine

the second problem should be due to a faulty motherboard or the ram sticks would not be properly placed they should make c clicking sound while puttig in their socket

the chances are rare to get to dead psu

the main problem will be the case

try to power outside the case with the faulty psus

it should work

Thanks for the answer.
I opened the case and I tried powering up the computer with the button on the motherboard, yet nothing happened.

I am almost 100% sure the ram sticks are correctly placed.
Is the problem the motherboard then? =/

By the way! I discovered the "Clr cmos" button on the back of the motherboard. When I press it, my computer gets power for maybe half a second, and then nothing. Wonder if it can help.

 

[serialkiller]

that button is to clear the bios if the pc crashed or the bios gets damaged or what so ever

it can be possible thatthe bother board can be damaged due to static charge or it is a faulty

do a rma on motherboard and get it replaced

even if the system gets failed then it is a psu or a ram problem

try putting only one stick of ram check both ram ctick and swap with the sockets

this should do it

I took the motherboard out of the case, and I tried powering it with only the ram, PSU and CPU. Didn't work. I swapped with the rams sockets. Nothing.

I tried doing the paper clip thing to try the PSU. I plugged a case fan to try it. It got power for half a second and then it stopped, again.

Is it possible that I have a faulty piece in my build that scrap my power supplys?

 

[serialkiller]

ok my friend had the same problem he played for 4 hours on pc and the pc got crashed

then he thought that the psu got burned due to excessive playing

then i contacted him yesterday he said his motherboard had gone down and he changed his mobo and to a safe side he also changed his psu


this should definitely work

That's pretty much was I was about to do. Thanks a buch for the support serialkiller. =)
