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.

Hilarious to say the least.. The PSU, no matter how much powerful, is not going to damage any component.. Unless of course you've done some messing with the connections and/or there existed some sort of short..

The PSU will not put out more power than the user needs (in this case your system). The hardware engineer is no engineer because of what he is saying is not true. You could install a 1000watt psu and it should not do what he is saying.

:D  :D 

Who is that engineer man... Still laughing! You have one of the finest PSU's in that segment. RMA it if you can. Hope its still in warranty.

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).

The Corsair 550 VX is a great PSU. But even if you put a 1000 watt PSU in there (massive overkill), the motherboard and the rest of the system will not draw any more power than it needs.
