Hey, have you listed a price, location and how much shipping would be to other parts of New Zealand? Also if you are asking for a PM make sure your Privacy settings allow your account to receive PM otherwise people can't contact you. Also note if you are selling something we ask you to offer to other members first. Links to private sales (including Trade Me posts) aren't accepted anymore and will be removed.

What model power supply is it? And what GPU do you have? Chances are you just have a dodgy power supply

Bollocks, there aren't that many computers around that'll draw more than a 500W power supply can produce (300w would be more than enough for a lot of them). People gamers over spec the hell out of power supplies and there's just no need for it, all you do is increase the power bill a little bit.

Check all the fans are actually working, and check the heatsinks and any inlets for dust. The most common cause of random shutdowns is heat.
Also fun a RAM test, bad ram can cause the same problem
I suggest you enter your specs into an online power supply calculator and see what it recommends, that'll give you a pretty good idea. Then it's probably worth your money paying for a new one that has a warranty. Buy the cheapest good one that is the same as or more than the calculator recommends.

Good advice here, op is running 3 hard disks and a 660 gpu, I would recommend 600-650w plus for this spec based on other builds I have done

I took a stab in the dark at your system specs and came out well under 500W, I strongly recommend calculating what you need, otherwise you may end up wasting money on extra capacity you simply don't need.

your really giving bad advice here - what if OP wants to upgrade in the future and he only brought bare bones to start with 

extra hard drives, more usb peripherals  sli GPU, more ram  - the list goes on.......

- go for at least 650 for what you have " a nvdidia 660"

Most of which add negligible power demands and the only one that doesn't is something that 0.1% of people end up doing. I'd recommend just getting a 450-550w unit from a reputable brand.

Something like this would be fine: http://pricespy.co.nz/product.php?p=904886
