Scythe Kamariki 4 550 W is a good power supply. It can really deliver 550 W at 45º C and during our tests we could pull up to 731 W from it. Efficiency was between 82% and 83% when we pulled between 40% and 80% from its labeled capacity (between 220 W and 440 W) and noise level was always relatively low.

It will please the average user looking for a good mainstream unit, as it provides eight SATA power connectors and two six/eight-pin video card auxiliary power connectors, plus the ability to control the speed of fans located inside the case depending on the power supply internal temperature.

In summary, it is a good but not outstanding power supply, being an honest product that will get the job done. Its success will mainly depend on the price tag it will reach the market.
