Power supply

 

I wanna upgrade my Cpu, motherboard and my powersuppy. my only problem is about the voltage if it delivers too much voltage. Heres the hardware i wanna upgrade to.

I hope you guys and girls can help!

 

Actually, voltage can only really change things if the current isn't worked properly, and I wouldn't expect a power supply to do that on a whim. Why exactly are you worried about the voltage being too high, because if it is that just means more wattage unless the current is lowered, in which case it's the same or lower...?

Thetb0. Well i just wanted to be sure because im not a that good at pc i just know the hardware. So i wanted to be sure so the warranty would cover it.

oh im sorry i fogot to add the power supply i have now. 

Revised Post:

A stock cooler may be fine but generally there are better coolers that can do the same job quieter/better and the thermal paste on the stock isn't that good.

The CXM 750 PSU will be fine for single GPU setup. But, you don;t really need 750W for a single GPU setup. a CXM 600 would be fine and you can get some dust filters/ intake fans if you want.

First of all, each of the PSU cables, ANY PSU cables, deliver the exact amount of voltage: 12V, 3V (EDIT: it's 3.3V, not 3V) and 5V. They are designed to work like this.

I think what you are asking for is power, which measured in watts (W). Power (P) is voltage times intensity. Voltage (U) is measured in volts (the symbol for volt is V), and current intensity (I) in amperes (A).

I would say that a 550W power supply should be enough for your build. I recommend the Seasonic S12G-550W. It's a very good and a very cheap gold rated power supply.
