In over 35 years of buying PSU's &/or building systems.... I don't think I have ever seen a unit in a plastic film wrap type.  In a plastic bag or cloth bag sure, but never in a film wrap.
 
 
*EDIT* unless you mean the outside retail box ?  - then every single new unit has always been in plastic wrap *

Nearly all major PSU and other hardware manufacturers use some form of tamper evident seals, whether its plastic wrap or stickers (EVGA uses both), that way it is evident whether the product is new or has been previously opened.

myself i had rather pay a little more for peace of mind still could be bad though

The original retailer said it might or might not come wrapped in plastic seal. When I tried to reinforce them and tell me whether that is 100% brand new and that Seasonic Taiwan did tell me that all their PSUs come sealed with plastic wrap, he didn't responded, that made me wonder.
 
I was always suspicious about their stuff, as if they have either open box and claiming new or something else.
 
Thankfully Canada Computers had 1 brand new so I grabbed that one and it came wrapped in plastic seal.
 
Thanks guys for your input.

I use the original cables. I prefer lower ripple as it keeps your hardware in better shape, and your hardware will last longer. Higher ripple damages hardware faster.

No problem.

Since you have the same PSU there is no better person to ask what is a bit disappointing to me with my new Seasonic 1300W Prime Platinum. 
My 14 year old 1200W Platinum was still running great, and the reason I decided to buy a new one  because the fan would come on to frequently (every 5-6min.) just browsing internet  and I thought internals were getting to hot,  so this might be a sign to get new one.
 
I just installed my new 1300W Prime Platinum and I am  a little bit disappointed, the fan comes on frequently and at only around 200Watts load and there is no really fan curve, It just goes to high mode, just like the 1200W Platinum did.
 
I don't think I made a mistake purchasing new PSU, the 1200W Platinum was at least 14 years old, if not more and I didn't want to put my components at risk of damage as you don't know what can happen to a PSU at that age.
 
Also, either its me or something was up with my older PSU. Now with the new PSU my system seem more responsive..am I just delusional?
 
My question is, does your fan comes on often, even when you not doing anything, like I said, mine comes on at around 200W and its fairly loud, it sounds similar to the 1200W, but I thought fan should not spin until you on 40% load, what’s the deal?
 
My PSU is in Caselabs S8S, fan facing down the case’s floor and there is about 2cm from the fan to bottom desk, so yes, there isn't much air going to it, but still, feels a bit disappointing, It’s about 22 Celsius ambient…Oh, also everything is connected to Cyberpower UPS
 
I love Seasonic, that’s all I have ever been using, so even if this sounds of the fan and frequency of going ON and OFF is normal I can live with that, but I need to know that this is the nature of this particular PSU and not something I should be worry now, although I heard few people mentioned laud fan, but no one speaks of fan been active every so often even when not doing anything.
 
Thanks
 
 

2cm space between fan and my desk making? I don't know, It was the same with my 1200W platinum so I know its by design. I thought since then Seasonic would change fans or something to make the fan quieter, it is loud, exactly like the 1200W. I went for 1300W thinking bigger will keep fan off longer (40% load) its not happening
 
I'm in 22C ambient so its not that warm

Replied to your PM AWK16.

Just believe in keeping things cool. Can't really comment on the noise as my system isn't quiet.

No problem.
