Post Problem -New computer build

Hey guys,

I'm having a problem with my first computer build. First, here are the specs;

Motherboard - MSI Z87 G45
CPU - i7
Fan - Noctua NH D14 (didn't know how big it was till I got it)
Ram - g.skill trident 2x8GB (had to take the top off otherwise it wouldn't fit under the giant fan)
PSU - Seasonic G series 550watt

There's a bunch of other things but I don't think it's relevant to my problem.

Basically after 2 weeks of being careful and putting together my new computer I go ahead and start it up and it won't start. No lights or anything. I tried a bunch of things and in the end I just plugged in the PSU from my old computer. Don't know the brand it just says cooler mast 520watt. Anyways I used that PSU instead and it worked. The computer booted up and everything. Then I tried using the seasonic one again and it still won't work, and now my old PSU won't work either.

It's most probably a PSU problem. My question is; should I use a specific PSU for this motherboard?

Question 2: my optical drive is super old that I need to use an EDE cable, does the MSI motherboard have an EDE cable plugin? Or should I get a EDE to SATA converter cable.

Thanks in advance for any useful information : 3

sometimes there's an on/off button on the back of the power supply near the AC cord and it comes from the factory in the Off position.

Update: using my old computer's PSU, every time I turn it on the light goes on and the fan starts spinning for a split second before everything shuts down again.

And yes I am aware of the on and off switch of a PSU.

Did you damage your old PSU while you had it plugged into your new computer?

I would just RMA the new PSU. They have a pretty high failure rate, no its usually not an issue to send it back.

If youve killed two previously working PSUs, Id be worried something on your system is breaking them. A faulty power lead, power extension, motherboard, something on the motherboard/case shorting out.

i'ld be looking to make sure the board was mounted properly.... especially if you smoked two PSU (one of which was known good).
