Either will be fine. Be sure you have some strong plastic cable ties to cinch up the extra cable after install. Otherwise, you have some air flow blockage with either power supply.
Once installed, you will never see or think about the power supply again, so don't get too excited about the lights and fancy stuff.
You can get buy with a less expenisive power supply. But the rebate makes them worth it. Be sure you have downloaded and printed the rebate form before the order arrives so you are ready to immediately send in the rebate paperwork EXACTLY as they want it done. Any variation and no rebate. Also, the rebate can take months.
