Edit: Thanks for the update Sidehack. You do amazing work.

I have the same one new in the box as well I would think that will work just fine
It will, some retailer here sell 5A psu to go along with those Oricon 10 slot usb 2.0. I'm not sure how the stock PSU will deal at 100% load 24/7 and you wont have headroom for OC, etc. But unless you have 9-10 sticks, this isint a problem.
