Tagan TG600-U33II - OEM, platform?

[rafal_iB_PL]

Anyone has more info about this unit? I found review of TG500-U33II @anandtech, but it was old one, and not sure if 600W model shares the same platform, as it's quite a bit more powerful. UL number suggests Impervio, but some units have inexplicably combined +12V limit listed as 500W (or 48A, which would equal to 576W). Any reviews would be handy too.

Thanks in advance.
