This kit uses 820uF 2.5v Fujitsu FPCap conductive polymer aluminum solid capacitors to replace the 1800uF 6.3v Rubycon aluminum electrolytic capacitors found in our other GX-280 kit.
Polymer capacitors have a much longer life and are not affected by heat nearly as much as their electrolytic counterparts. This change has been tested and does not pose any issues. These polymer capacitors are usually found on high end video cards and motherboards and used frequently by overclockers. The only downside to polymer replacement caps has been the cost and availability; I got a great deal on these and am keeping the price low!
The voltage change will not matter because the vcore on these is never more than 1.75v, most are around 1.47v so 2.5v leaves a good margin. The capacitance change is ok due to the Super low ESR and high ripple current rating of the polymer.
