    As long as you have a receipt for proof of purchase it doesn't matter because the place where you bought it from will either have to give you a replacement (same make or another) or your money back which you use to buy another PSU [​IMG].

    It sounds like you haven't completely ruled out a faulty power switch. Take everything off the case headers and bridge the power pins with a ball-point pen.

    there should be an LED on the motherboard somewhere when you have plugged everything in. if its on you can rule out psu. otherwise do a simple test usingthis guide

    instead of using a harddrive or something, test it with a case fan. if the fans start rotating then its some thing thats up with the motherboard.

    The motherboard could be shorting off the case or another component. This has happened to me a few times where for safety reasons the computer will not turn on at all. Repositioning the board in the case usually fixed the problem once I identified it.

    Take the motherboard out of the case, next get a large static bag and some foam, lay the static bag on the foam and place the motherboard on the static bag. From there assemble your computer for testing purposes, just use the very basic components to see if it'll boot from outside the case. One stick of ram, GPU, CPU, PSU and the power switch from the case connected.

    Your HDD lead seems to be around the wrong way + is on the neg is the power switch the same?
    Unplug your power supply from motherboard there should 1 green wire in the 24 pin use a wire to connect the green wire to any black wire and turn on to see if the fans start

    Fan's didn't start. It made a slight and short "bzzt" sound though (not when I flipped the switch) when the psu was on and I inserted the paper clip.

    has the PSU got dual voltages?

    Edit: scratch that, just saw the pics in the previous page. I guess 110v must be ok for Canada. You would have known if it wasn't, big blue flash and a loud bang!

    The psu is suppose to be OFF when you insert the connection wire!
    The "bzzt" sound was probably your fuse blowing as you inserted the wire into a live circuit

    I know it's supposed to be off, I did it that way first, and it was silent.

    Some PSUs won't turn on Green to earth. The correct start up that works for all PSUs is green to grey (PS_ON to PWR_OK). Earthing out PS_ON will work on most PSUs but it is not correct. Don't leave it turned on for too long in this condition, PSUs do not like running without a load.

    Edit: leave the paper clip in the connector while you quickly test it. If you just touch it momentarily it will turn on for a split second and then off again. This could be why you heard a quick buzz and then nothing happend.

    It made the quick bzzt when I turned it on after connecting green to grey, but that's about it. Since it's a Saturday I'm 99% sure NCIX is closed unfortunately [​IMG]

    Sorry to hear that it's not working out. The online customer support for NCIX is closed today, but if you live in the Greater Vancouver area you can actually walk into the stores for in-person assistance. If not, you should leave them an RMA message ASAP and they'll likely solve it for you on Monday.

    You just might be able to. I can't confirm for sure that they have a competent and/or enough staff there though.

    In terms of numbers, they have more than enough staff it seems.
