Sorry to hear that the information in my document is not accurate. But since I know nothing about electronics, I used information from this forum. Somewhere is written that 2 nozzles takes about 120W and the 12V heatbed needs another 100W. Is the remaining 100V not enough for the rest of the printer needs?

Don’t be sorry @svdv , your effort in the document has helpt me alot, the latest information regarding W requirments is new to me aswell after reading hundres of threads before jumping on the installation. - Without the document (and Marlaks heatbed) I would still be bying Buildtak and not beeing able to print ABS and even having issues with the larger PLA prints. Now I manage to print on the whole buildplatform and still have an 90% successrate vs 30-40% before. Vertex with heatbed is doubling the value of the printer. Thank you.
Using orignal PSU for the vertex, and RSP-320 only for the heatbed seams to work. RSP-320 shuts itself of if it is overloaded so I dont belive there will be issues with it being a bit undersized, but for those using thinking about extending to a similar setup go for a larger PSU, >350w for 15V.
