these details have been posted here on this forum.
If you're confident in your assertion that details have been posted on this forum then back it up by providing a link.
It's important to note that Black Arrow have delivered nothing at this stage and everything they have said has been contradicted by their their own subsequent [spurious?] updates, so rather than just slack-jawing that 'something was said on the forum' how about you actually follow what's happened and appreciate that almost everything that BA have said up till now has been utter bullshit.
Maybe if BA finally get a product launched then they'll be in a position to publish information that can be relied upon, but you'll appreciate that the commentator above inquiring about exact specs is absolutely correct in seeking confirmed information from BA rather than potentially wasting more money on a power supply that isn't suitable for the requirements.
BA have said a lot, "Ya, ya, we're absolutely confident we can deliver in February..." but their words have proven to be garbage, they can't even communicate with their customers in a unified way and instead there's a revolving door of apparently well-meaning nobodies who parrot whatever rubbish BA feeds them, meanwhile customers are supposed to wait and wait and wait and give them the benefit of the doubt? - Nope, the real world doesn't work that way.
