Hello, I'm doing my first build. I have a Thermaltake 450 watt PSU, an AMD Phenom II x2 CPU, an ASUS M4A88T-M motherboard, and two 4-GB Patriot memory modules (8-GB's total). I've installed a 1.5 TB HDD and a DVD-RW. Everything went pretty well up to now. I'm wondering about the unused wires from my power supply.
There are always unused power connectors, just leave them be and all will be well. If they really bother you then use a twist tie or zip tie and move them somewhere you cannot see them (just dont kink the wires!)
