Would putting a higher voltage PSU in my CPU have any risks?? What if I just buy a 1000w power supply, wouldn't it blow something? Or would it just take what it needs and leave the rest ?

Answer 1

it will draw the power that it needs

Answer 2

The power supply must put out the proper voltages, and the various devices will draw the current (and hence the wattage) they need. I agree with Raynaud's answer - you probably need more power (in watts), but the unit must supply the same voltages as the one you're using so as not to fry the components.

Answer 3

I don't think its possible to put a higher voltage power supply in a computer. Power supplies do come in assorted wattage's, it all depends on what hardware is installed in your computer. Check out the link to get some insight on how to choose a power supply. Too high of a wattage doesn't mean its better.

Answer 4

The power supply in the computer is only a transformer.
The power is coming from your home power lines.
Any transformer will only supply as much power as the load on it requires [in normal operation], there are such things as lightning strikes or voltage surges that can blow things, but they are rare.
1000 watts would be overkill [if you could find one] due to cost, 450 watts will be cheaper and sufficient for all except very loaded computers [multiple processors, multiple video cards or similar situations].

Answer 5

If the interior resistance is sufficient to shrink the present to approximately 10 mA or much less, then you certainly would not have the flexibility to get sufficient modern to reason a extreme ask your self. Even a proscribing resistance that limits to an more suitable modern, say 50 mA, can nonetheless enhance the protection, as 50 mA reduces the possibility of dying from a ask your self, while in comparison with a number of hundred mA. .

Answer 6

If you're replacing a dead power supply, you should get the exacly replacement. Otherwise, you could burn up your motherboard by the power supply causing too much heat. Your fans can only cool so much.
