Hi
I presume you are talking about unmodified 5 chip gridseeds?
If so, yes indeed!
Even if they are modified, you should be fine running them with that power supply.
I forget the exact current that the modified units pull each but I have been powering 12 modified GS5 pods with a 25 Amp 12V which provides plenty of overhead, for over a year now without any problems. I've also been safely powering another 13 of them with a 30A power supply for the same period of time so you should be good to go!
But...remember!
What ever happens, you are fully responsible for the results!
God speed!
