i need a psu (duh) but i need one of an extremely small form factor. im making a new system in a Xbox 360 chassis(broke, and was collecting dust. and i need a small rig to at least play games on while travelling. I do that a lot) and i need a small psu/ some way to power it. ive seen this PSU and im wondering on anything smaller(alot to ask) or more wattage for size, and reliability. please give me feedback, thanks 
PS: i will be powering an AMD A8 3870K CPU/an FM2 socket alternative(when available)
