Pre-ordered one, excited

Which psu do you guys recommend me to get to power the L3+?
Should I go with antminer official one or just grab a regular computer platinum psu from Amazon?
I have pre-ordered one too, but I'm kinda affraid of the lack of communication regarding the issue when you proceed with a USD wire transfer. Lot of people had their preorder cancelled after a week, without any money back. And some people seems to be waiting for more than 20 days. I just hope this will not happen to me.
Regarding your question, the official one is out of stock yet. So I think the only alternative is to buy one from amazon... which isn't mounted btw.
"Bitmain recommends the new PSU that is especially designed for the Antminer L3+ and will be available to purchase after 20 June 2017 with shipping start date before that of this Antminer L3+ batch."
