When do you know when your PSU is too small?

At the moment I have a 500W power supply and I'm getting random crashes every other day.
I've also just got my new Q9550 and if I test the OC with Prime95 it passes a 6 hour test.

Any ideas?

Hey Ben if you have the SLB8V S-Spec E0 stepping CPU I can tell you that 500 watts is not gonna do it no matter how good your amperage is because of your Overclock. Look for a single rail 40 amp or better on +12V for OCing with your unit

Never heard of that before. Could you point me to one.

Thanks

Q9500 is 95 watt at standard speed draws more power than Q9300. You are pretty heavily OC'd on a 2.83GHz core
 
Look on your box Ben at your S-Spec. The cooler 65Watt core was the Q9550S which are rare at least around here. They don't draw as much power. The S-Spec SLB8V was a later revision of the Q9550 and a faster core and now most common

What site do you look at in Aussieland to get parts I will go there and look as well?

Here ya go-something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005

My favorite is PC Power and Cooling but lots of wires to deal with
 
Ben...Look at this PSU....http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006


Look at the spec page on it...

Notice ...Under Outputthis where it says its a 60Amp on the +12V rail.....Thats what you need.. Its the +12 rail that pushes your CPU...

Man..Sorry about all the tripple quotes there...I tried to copy / paste like 5 times and it never showed...But I guess after I posted the post it was actually all there...LOL

Go figure
 
What brand PSU is it? You can have a solid 550W PSU that can power an i7 system. But if you have a junk brand it won't work

The main things you are concerned about is amps on the 12V rail or rails
