Does Power supply matter for overclocking?

[bhungy]

Does overclocking matter when it comes to overclocking a 1.2 ghz tbird to 1.4 or 1.5 if possibe?

I've heard it does, because often you have to change the core voltage on the CPU to get it to run stable overclocked (however, you can get a stable overclocked cpu to run at the standard core voltage).

Not quite sure I understand exactly what you are asking, but in any event the answer is yes to either case.

In connection with power supply unit (PSU) quality is important. I would suggest that you would be well advised to purchase one approved by AMD for the processor you have. In my work experience, stabililty problems have very often been traced to poor supply feeds from the PSU.

If on the other hand you are referring to voltage supplied to CPU, then yes here too. In brief, the more you expect to OC, the more you should expect to have to increase voltage to CPU to obtain stable system.

Hope this helps.

It matters a lot. You have to have a PS that is high quality and has enough wattage. If you have a low quality PS it can sometimes put out bad power. In a normally clocked system that's not a problem, but in OCed systems it can seriously hamper overclocking attempts.

If you want stability it matters quite a lot.

Disregard that comment about enermax's 550W P/S cuz it's a bunch of bs. Enermax's are great PSU's...don't believe me...check my post..."OCers with Enermax P/S...pls post ur results". 400W + is a must for achieving stability at high speeds. My vote goes for the enermax 431 W.
