Perhaps @guryhwa and @1461748123 might be able to give some better answers on bricks over 400W. I believe their company includes specially modified high power bricks to power their 400w+ DC ATX PSUs.
Yes I do, but the product description and images are kinda outdated:Do you have links to these units?
Nope, thats why I said the page is a bit outdated If you plan to use the 5.5x2.5 dc jack then 2 connectors are crucial. We are now using the Molex 8pin connector which can handle high current, so no need for 2 connectors anymoreOkay so this is either meant to power a DC-DC board with two inputs or alternatively two separate boards?
YepAnd the form factor is the same as the 330W Dell with no additional heat problems etc?
Yah, I would recommend the HD-PLEX 300 watt "combination" coming out soon.Would either of these work OK for a 970 and a 4790K?
