Solved Power supply adequate for my new setup?

Specs: Windows Vista
I just purchased a new processor and was wondering if I needed to upgrade my power supply as well to account for the change in watt usage. My specs are:

AMD Phenom II 965 - 3.4 Ghz
4GB DDR2 (Ram)
Windows Vista
AMD Radeon HD 6670

I currently have a 400 watt output power supply.

I did the wattage math in my head, and basically the processor, graphics card, and ram would go up to a maximum of 300 watts. Unless I'm missing something, which is very possible, it seems I could just stay with my 400 watt?

Good idea or bad idea?

The important factor is having a 12V Single Rail of 28A++, please post this info..

ARM Devices are the future, great British Design !

Have you installed it yet? I doubt by changing a cpu that it will make any difference. If you were to upgrade the graphics card, that would be a different story. Like Jolicloud stated, a single 12 volt rail is always better to supply proper amperage to the components. Install the new cpu and try it. If it works, you win.

Well, it says "12V2 18DA" on it. Not sure what that means precisely.

I have not installed it yet. Just waiting on the shipping. I imagined my PC blowing up if the wattage was too much for the power supply. What is the real case? Worst case scenario, my PC just crashes?

It won't blow up. Worse case scenario is it won't boot up. I don't see it as a problem.

The Phenom II 965 is a 125W CPU. Does your motherboard support 125W CPUs? Many of them do not. It would help to post the make/model of your board plus the CPU you're upgrading from. Did you check the board's CPU support list before ordering the new CPU? Did you check whether a BIOS upgrade is necessary?

I did check the support list and yes, my motherboard is compatible with the new CPU. The motherboard model number is M3N78-VM from Asustek.

Not sure if a BIOS upgrade is required though.
