What other equipment would I need? I paid for the hosting option because I didn't want to have to worry about setting everything up. So what do I need to buy? How would I set them up? Also how long would it take for him to ship it? Also how much do you estimate I will get back if I start mining as soon as it is shipped to me?
You just need a computer and depending on how many you ordered, a hub. You can probably make around 0.1 in the next month per miner.
What kind of PSU do I need? Do I need anything else?
As I mentioned,read about 5-10 pages back,you"ll find info about those of us that have gotten our units & how we got em to work

Each miner will consume about 60 watts (approx.) @ 350MHz,which = about 5.5GH.Stock clock is 282MHz= about 45-50 watts.So use your best judgement on PSU selection with that info,depending on how many units you will be running.
Klondikes come with USB cable & for every 2 you ordered,you'll get a 6pin PCIE splitter

Here's more info:

Up to 92% efficient, fully modular, and top quality (Seasonic KM3 core). Watch out for similarly named older products that aren't as good.
