Watch out man, PSU failure is dangerous. Don't hesitate to buy a high quality power supply even if its a bit expensive.
It's ok, it is pretty much like the clan war, with added rules which you can see on main Clan League thread. Since it is double bracket, we will be playing at least one more time with another clan in the loser bracket if we lose against Elite this time.
If we win, we have a week free to wait for the match between Obey vs whoever won in the first match, so yeah at least you have 2 weeks to fix your pc, lol.
