The Prismatic Shield Generator (PSG) is a high-capacity Shield Generator variant capable of absorbing more damage at the cost of a higher power draw and a lower recharge rate than standard Shield Generators. It is a Power-specific loyalty reward for Aisling Duval supporters.
An alternative shield generator that has greater than normal strength but requires a higher power draw and weight allowance.
— In-Game Description
The Prismatic Shield Generator's shield strength is almost equal to the shield strength of a standard Shield Generator that is one class higher. This represents a 15-20% difference in shield strength between a PSG and a standard SG of the same class and rating. However, the PSG comes with twice the mass, significantly more power-draw, a higher price, and unlock requirements through Powerplay, which makes them less convenient to purchase as well as more difficult to use efficiently on most combat ships.
Multipurpose ships equipped for combat usually have less severe power management issues and thus the capability to use a PSG in combat, although other modules may have to be downgraded to accommodate the PSG, depending on the ship. For traders, however, the PSG might be a welcome upgrade since most freighters should be able to cope with the power draw, especially since a ship outfitted for trading usually reserves its largest internal compartments for Cargo Racks, which do not require power. The only disadvantage in this case would be a slight decrease to jump-range due to the greater mass of the PSG.
- The Prismatic Shield Generator shows some green colour in addition to the blue effect when a shield is being hit, allowing other ships to visually identify the type of shield used.
