Look for a switch on the back of your power supply...

...or check for a stuck power button on the computer.theres no switch on the back of the power supply and even if i discount the power buten cables still turns on. What happened prior to this that prompted a PSU switch ? ?

First of all...you should answer patio's question on what prompted you to change the PSU in the first place. There had to be an issue with the computer prior to you replacing the PSU...correct? What was that problem?

Also...did you check to see if the "cheap" power supply you just bought is going to fit your computer...or if it has the same (or better) rating as your current power supply?

Is this a custom build...or is it a brand name computer?

I'll never understand why people scrimp on PSU's.....
Spend $1000.00 on a board, CPU and high end vid card and throw a $20.00 PSU at it and expect everything to be OK....
