I am no expert, but this explanation sounds extremely far fetched...

A.) 550W is not generally sufficient for Crossfire- unless you are using older cards.
B.) Many reviews do low load testing- and I believe PSUs are at peak efficiency ~ 60% of load, so 330W would be your peak efficiency level on this PSU... hard to imagine that a setup of Mobo, CPU, GPU, HDD, etc. cannot meet that number on a 550W.

idk, someone with my expertise than myself should chime in- but this sounds bogus to me.

Give the hardware engineer a whack on his head.
There is no such thing as a PSU being too much for the PC.The Corsair VX 550 W is a very good Power supply and can even handle high end graphics cards.Maybe the PSU was a bad one.Get it checked and if faulty ask for an RMA.
 
Hardware Engineer? I don't think so. Sounds more like a sales clerk that does not know anything about power supplies.

Corsair is a brand that has a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty (in the USA).
