Wccftech's 248W testing is based on tests from Reddit that listed 130W, both are wrong in their own ways. You'd be surprised how many sites are still reporting the 130W story, which is spreading some false but highly attractive info to miners regarding Vega.
Looking at Overclockers UK I can see that they have had supply of RX Vega GPUs quite consistently over the last week, with standard (non-pack) pricing. At least in the UK there isn't any real pricing issues ATM.
Yeah, it is mind boggling how many sites are reporting this all as fact, with PC gamer even having a piece on it.
That is interesting. In the US it's just completely sold out anywhere you look. Heck I can't even search for a RX 56 on most websites. It only shows the 64.
