I need to buy a new power supply for my rig and I've decided to go Enermax this time. However I am confused about the SKUs for Enermax products.

1st, I would like to know what is the difference between the Galaxy EVO
series versus the Revolution 85+ series.

At this point I'm trying to decide regarding the following product:

Enermax Evo Galaxy 1250W EPS12V ATX 24PIN Modular Power Supply

It is listed as EGX1250ETW-01. Can someone tell me if it's the crossfire or the
SLI version? the SKU is nowhere to be found on enermaxusa.com nor enermax.com on enermax.com.tw
