The Corsair TX650 V2 (CP-9020038-NA) that the OP linked to is made by CWT (Channel Well Technology).
You're thinking of the recently discontinued CMPSU-650TXV2 that is made by Seasonic.
Yes - I saw the v2 & the only one in the realhardtech database with a v2
was Seasoninc, their database must be missing a few models here and there,
or the model #'s might be truncated, so I stand corrected.
