One thing about new companies entering the PSU market is that the insides tend to be from a few recognized manufacturers so picking one up is not necessarily a bad idea, depending on what the insides are.  HEC-COMPUCASE are well known and while not top of the line they are recognized as providing decent power.  The RASURBO Real&Power 550 W is no exception … provided it was a 450W PSU.  It seems that RASURBO was a bit optimistic about the power rating as at that power draw TechPowerUp saw disturbing flucutations; however at 450W draw they were quite happy with the performance.

"We are always thrilled to see new companies enter the PSU market because this leads to more choice for the end users and competition gets tougher, reducing prices. Today we will take a look at RASURBO’s Real&Power 550 W, which is 80 PLUS certified, utilizes a semi modular cabling scheme and comes with attractive pricing."
