  1. PSU tier list : http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
    Different OEM.
    EVGA Supernova B2 made by Super Flower - tier 2 psu.
    EVGA Supernova NEXB - made by FSP - tier 3 psu.
  2. yeah.. u just dont take a b1.. take b2
  3. The B2 is a superflower based unit, higher quality than the B1.
    The B2 is also semi-modular where the B1 is not.
  4. What does that even mean lol so anyways nothing will happen if I buy the b1 like there won't be noticable differences?
  5. Best answer
    The B2 uses higher quality components that will tend to last longer.
    You can also remove the cables you wont be using from the B2.

    I recommend getting the B2 unit over the B1. The performance is the "same" but it is higher quality.
  6. okok.. u are not particularly good with tier list..
    tier list is a list created by tomshardware for people like us to get the best psu..
    tier 1 -very good psu
    tier 2 -good psu
    tier 3- average psu(u should avoid these from here)..
    b1 is a tier 3 psu which is not good for u pc and might damage your components when it fails..
    b2 is a tier 2 psu which is good with low failure rate..
  7. Thanks Lads! Cheers
