got a good deal on a saz1500 v2 .. what is the difference in the v2 and v3 .. I don't want to feel outdated lol. will be using it to power a 10 inch xcon sealed

v1- v2 would be the heat sink and fusing on the board,  and this

 

On 12v / 1 ohm nominal the v.2 is more powerful. This is how most customers use them so we optimized it for this.



On 16v and/or lower loads the v.1 is more powerful as of now -- we are
going to keep optimizing the new design to exceed the v.1 across the
board, though

 

here is a comparison to the 1500D v.2 model -- the new v.3 is longer to
fit all of the new parts and the fan but is narrower.

 

 and it has a fan

does the v2 have a fan

No
