DreamWare Computers posted a review on the Spire Rocketeer IV 600W Power
Supply

Founded in 1991, Spire is a well known manufacturer of PC cooling solutions, power supplies, and cases. We were very impressed with the first cooler that we reviewed from them about a year ago. I was happy when the opportunity came to review one of their 600W Rocketeer IV power supplies.
