Dear Sir,
You need to be more specific since there are several GPU cards with that name.
I have spoken to our product manager about the differences between the TPN-650 and our suggested HCG-620M.
Both PSU’s come from the same manufacturing plant and are similar in build.
However because development has not stand still, the HCG is better because of the components used are newer. (Making it more energy efficient)
Also the max power on rail 1 is higher which protects your GPU from under voltage.
You have mentioned also to be concerned about the number of connectors. Our product manager said that current PSU’s don’t have an excessive number of connectors anymore because they are not necessary. Even our latest top power supply (HCP 1300 Platinum) doesn’t have 10 connectors anymore.
Awaiting your reply.
