When buying a new power supply, do the amps matter?

flynntes · Oct 18, 2013

So I have bought a new power supply for my pc. The voltage is the same, but the current/ amps is not. I am wondering if this will fry my motherboard? I have a HP Pavillion p6220a specs are:
CPU: Intel Core 2 Duo E7500 @ 2.93GHz
RAM: 4GB
OLD PSU: Bestec ATX-250-12z (This is what I want to replace)
Graphics Card: Asus nvidia geforce 210
OS: Windows 7 Home Premium
Motherboard: MSI MS-7525
And I have a Antec Neo HE550

Amps do matter
Simply math shows it.
Voltage X amps=Watts. So lower amps across each rail, means less available wattage.

The computer will only draw how much it needs, you can not fry your computer by having too many amps. The problem arises when you do not have enough amps to power your parts. I think this is what you are asking? Does that answer your question?

Will too many amps break my motherboard, and i have a very low profile graphics card.

No, extra watts (which are essentially amps in theory) only are drawn when needed. So your rig takes what it needs.

Thanks, that answers my question! One more question though, I have an asus nvidia geforce 210 which draws 75 watt, will my power supply be enough?

It will be more than enough. You could get away with a 300W psu for that card. And antec typically make solid PSUs as well, and that particular one has lots of amps on the +12v rails so you should be good to go.
