Depends. What is your charger/power supply rated for? The TB itself can eat up to 1.8A (tested during high CPU usage), and adding keyboard and mouse bumps it up to 2A (also tested).
The power consumption of all devices (in amps) adds together, and if it exceeds the power supply rating, the tinker board can crash, or even worse, the power supply itself can get damaged.
I'm in no way an Tinker Board expert, I have it only for couple days, but that is general behaviour of electronics.
I used a VERY high quality 2A charger, I would say the best 2A charger available in the Czech Republic, and the TB crashed sometimes, so I had to order a 3A supply (for Banana Pi  Cool ) and now it runs good even with USB peripherals.
EDIT: cheap chargers are liars, before I bought the good (and expensive) one, I used one that was rated for 2.5A which cost me literaly 4 dollars, I brought it home, connected to a dummy load and measured that it gives up at 1.2A, then it just reduces voltage.
EDIT2: I returned it, they gave me back my money, and they had to remove it from stock
You may need an external power supply for an external USB hard disk drive. Most have a power socket
If it's a mechanical hard drive it will definitely need it

Hi nealscut,

The Tinker Board's USB total can provide up to 1.2A Current.
But...it also mean you need a more powerful's adaptor(Power) to push them.
