I just ordered the parts to build my new PC from newegg. As I already own a 400W PSU at home I didn't order a new one in order to save some money, but I am growing increasingly worried that this unit won't be enough to "safely" power my new computer. This is my PSU right here, it's supposed to be a reliable brand at the very least... although it's the most basic offering from this company : http://www.newegg.ca/Product/Product.aspx?Item=N82E16817139008&Tpk=corsair%20400w
Now here are the specs for my new PC :
AMD Athlon II X3 450
4GB DDR3 RAM
500GB Samsung Hard Drive
On a side note, I'm also wondering what would happen in the event that my Corsair PSU turns out to be insufficient to power my computer after a while ? Will it just die without damaging the rest of my hardware ? Will it go out with a catastrophic EMP shockwave that will revert my computer back to stone age ?
