Assembler and Modules

[Dima]

What is better more assembler with efficiency module or less with speed module ?

for example 2 assembler with 2 efficiency modules
or
1 assembler with 1 speed module.

I always put four yield modules on refineries to double their output (you'll get twice the mass of ingots from ore or scrap that way), and I always put four speed modules on assemblers to maximize their throughput.

It all depends on where you are, how easy it is to find the resources, and how much of a rush you are in to build the next big project :)

I go for the gold early. I've found it's well worth the extra effort early on to get that first refinery built with yield modules. After that everything I'm mining and refining has double the output for the same processing time. Then soon, very soon, the world is mine! Mu-ha-ha!

1 assembler with a speed module is the same as having 2 assembler, with the difference that 2 assembler can produce 2 different items at the same time but also using more PCU.

5 assembler with 4 power efficiency modules each (That's 20 modules) are the same as 1 assembler (Power wise) but costing a lot more and are also PCU heavy. But we can produce 5 times as "fast" with the same energy.

So theoretically if PCU, component costs and space is not an issue, then power efficiency modules are the best! On the other side power is almost never an issue and PCU is, so speed modules are a better choice.
I think PCU was also one of the mainreasons why those modules were made.

Not even knew PCU is a thing.
Thank you

If you include the PCU cost of wind turbines needed to power the assemblers, 1:3 speed:power is the most cost effective (0:4 and 2:2 are also good, 4:0 is worst). This is even more significant with solar panels, since they produce less but have the same pcu cost as turbines.

However, batteries only cost 15 pcu and can power arrays of assemblers by themselves, provided they're allowed idle time to recharge.
