I still remember that a guy came here from Opus (we found out that) and start talking about 300W DC-DC PSU. And that was like 2 yrs ago, but nothing coming out.
And come DragonBTV also talking about 300W PSU, but nothing out yet.
And Jeff was talking about putting 2 DS-ATX together in master-slave mode to produce 400W PSU, but nothing yet.
Until then, my home-built Sproggy is the most powerfull one
