Power Shards are special items used for overclocking buildings. Each shard increases the maximum allowed clock speed by 50%. A building can accept a maximum of three shards, which means a maximum running speed of 250% for production buildings or 202% for power generation buildings (due to overclocking not being linear)..

Resource acquisition[]

Slug Color Blue Yellow Purple Total
Slug Number 400 212 117 729
Power Shards 399 422 580 1401

There are currently 729 Power Slugs known in-game; 400 blue, 212 yellow, and 117 purple. 1 slug of each type is consumed as part of research in the MAM. The upper limit of obtainable Power Shards is infinite, as Lizard Doggos can generate an infinite amount of slugs over time. The upper limit of non-renewable collectible Power Shards is 1401.

Additional power shards can be randomly obtained as drops from the FICSMAS calendar.

Maximum throughput requirements[]

It is best to use Power Shards to overclock raw resource extractors (Miners, Oil Extractors, and Resource Well Pressurizers) to saturate a conveyor or pipe throughput. The total required Power Shards equals 1,145, leaving 286 of the non-renewable shards. This can be used to overclock 95 Water Extractors to attain maximum raw resource production.

The minimum number of required Power Shards to maximize throughput is as follows:

Miner Nodes
Node Purity Number of Nodes Number of Shards
Impure 76 228
Normal 185 555
Pure 112 224*
Total 373 1007

*Pure nodes only require 2 Power Shards to achieve 162.5% / 780 items per minute limit

Oil Extractor Nodes
Node Purity Number of Nodes Number of Shards
Impure 10 30
Normal 12 36
Pure 8 24
Total 30 90
Resource Wells
Resource Number of Nodes Number of Shards
Water* 8 24
Other 8 24
Total 16 48

*Water Resource Wells are power inefficient versus Water Extractors, however provide a higher output per Power Shard.


Power Shards can not be sunk into the AWESOME Sink


Power Shards are used solely for overclocking. See Clock Speed for more details.


  • Overclocking production buildings will always result in greater power consumption than simply creating more buildings, though there are cases for doing so to simplify production numbers, reduce beltwork, or to reduce machine count for space or performance reasons. Overclocking power generators will often cause power production to not be a whole number, making them considerably more difficult to use efficiently.
  • Underclocking a building does not require any power shards.
  • Power Shards are renewable by taming Lizard Doggos, as they have a chance to find new Power Slugs.
  • It is a common misconception that Power Shards "wear out" after a certain period of time: this is probably a result of half-remembered statements from older builds when they could be used as vehicle fuel. The disadvantage of overclocking is increased power consumption (or uneven consumption rate for generators) as mentioned above, not that the shards are temporary.


  • Patch Copy paste now autofills Power Shard slots if available
  • Patch Production times changed to work better with Constructor sounds. Crafting clicks adjusted.
  • Patch 0.1.11: Power Shards can no longer be used as fuel.
