PSU doesn't come with required 24+8+4 pin connector

[shudson250]

Doing a home build:
Asrock x399 Pro Fatal1ty
AMD 1920x threadripper
Evga GTX 1060
2x8gb Corsair ddr4 3000mhz vengeance ram
Evga 650W G3

I figured the 650w would be enough power; seemed that way from forum chats and online calculators - Asrock also makes no mention of required psu.

I put together the build, but PSU only comes with 24 pin and 1x8(4+4). Asrock has an additional 4-pin power connector for the cpu, which I try to complete without connecting. Obviously cpu doesn't get its power so when I fire it up, everything goes as normal but the Dr. Debug shows error 00 - cpu error. Okay, so I discover the extra 4 pin is definitely required.

Do I need to upgrade the PSU to a 750? Or can I get some cable that will help me out? Has anyone else run into this problem?

The required connectors for the motherboard are literally the first thing ASRock lists.

EVGA reduced the number of connectors from the 650 G2 to the 650 G3. You will need a PSU with the proper connection, there's no workaround here.

Yeah I saw that after posting :|
First build in 15 years so I didn't know to check that kind of compatibility.

Thanks for the definite answer.
