I have been confused between buying an Antec450P and an Antec 550P. For each, I came across the below reviews.

Antec550P
https://www.techpowerup.com/reviews/Antec/VP550P/
I did not find a hardwaresecrets review of the 550 Model. Not sure how credible techpowerup is.
The 450 review by hardwaresecrets says that "The MOVs are located in parallel with the electrolytic capacitors from the voltage doubler circuit." It's mentioned here
While the 550 review by techpowerup says "Unfortunately there is no MOV (Metal Oxide Varistor) present so the PSU is susceptible to spikes coming from the power grid, unless you use a surge protector with it." This is mentioned here.
Moreover, Antec's website mentions "Surge & Inrush Protection (SIP)" as one of it's protections under "CircuitShield™"
Things don't quite add up
1. How does a PSU with no MOV provide surge protection
2. How come the 450 model has it, but for the 550 they've removed it. (450 is by FSP while 550 is by Delta from what I hear, after all that I have read about Delta, finding it hard to believe Delta would choose to remove an MOV.)
3. Even the hardwaresecrets review does not mark the MOV on the image (they usually do), could it be that it's placed at an unconventional location and hence got missed out by techpowerup (550 review)
All in all, can anyone confirm if the 550 model has an MOV or really does not as it's the only deal breaker for me at the moment.
