I'm not sure I understand what you mean by buying a more powerful PSU. I thought I already bought a pretty expensive one! Please tell me the benefits of buying an even more powerful PSU...if possible please suggest a Coolermaster one as that is the brand available readily in my city.
What exactly is 50% load peak efficiency?
This was a machine I bought for work and will install the LINUX OS on it, so that's why didn't buy a graphics card. Was that a good decision? Just added a USB wi-fi card though, I forgot to order it.
