I'm looking at buying a barebones kit to build a new PC. However, I'm noticing they've bundled a 140 Watt CPU with a motherboard that lists as supporting up to 125 Watt. I'm wondering what would happen if I went ahead and bought it and assembled it. I'm hearing that it will power-starve the CPU, but I'm not sure I'm understanding what effects "power-starving" it would do.
