Power Supply Comparison - HX1200i vs PRIME 1200W Platinum

[volkgren]

I already ordered the HX1200i because I saw the efficiency results to be higher, but now I realize all efficiency results are higher on this website https://www.kitguru.net/components/power-supplies/zardon/seasonic-prime-1200w-platinum-psu-review/5/

when compared to http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story3&reid=511

Kitguru shows 94.2% @ 600W and JohnnyGuru shows 91.9%.

Why is there so much difference there? I didn't see a review for the HX1200i on JohnnyGuru.

I suppose I'm feeling some kind of way about making my purchase based on misleading information.

My use will be in a multi-GPU mining rig using between 850-1000W 24/7.

My question is the HX1200i better than the PRIME 1200W Platinum? I know the Corsair has the Corsair Link technology. Is that the main difference?

hxi - lambda-a
seasonic prime lambda-S

corsair link is a software to check your voltages of your psu.

get whatever you want, it wont matter.

Thanks.

But what's the lambda-a and lambda-s ?

 

[superninja12]

its a more in dept energy efficiency label (like 80+ gold bronze etc) , they are way more strict(e.g. vampire power 5vsb). to get a labda certication the powersupply goes through a hell for 1-2weeks.

they also rate noise.

edit: I got that wrong , lambda is the noise rating and eta is the efficiency rating.

Awesome stuff. So they are both ETA-A efficiency. Cool.
