Is the +4 pin EPS CPU power necessary after having the 8pin(4+4) (NOT OVERCLOCKING)

[Sykes]

Im upgrading my cpu to ryzen 3700X and motherboard to msi b450 pro carbon AC.... PSU is antec vp550 v2

Is it necessary to connect the additonal 4 pin connector to the board after the (8-pin) connector?my PSU doesnt have that connector

According to what i understand.... the The 8pin power connector is rated to deliver over 200 watts to your CPU. I dont think the ryzen will draw that much power in 99.9% cases.....

and im not even planning to OC.

The additional 4 pin connector is not required right? The system will be stable at loads right?

It should be just fine. If you want to be extra sure then just put the system under a heavy load and see if it is stable, which it should be. That extra connector is only really needed for extreme overclocking of the higher-end chips.

Wudnt be able to return it once iv bought it....need a sure answer 
 

Other parts - GPU - MSI RTX 2060 gamin Z, PSU - antec vp550 v2, SSD-970 evo 500gb, 16gb(8x2)3200mhz corsair RAM, 1TB HD+ 2TB HDD

The extra 8 pin is a completely useless addition outside of LN2 extreme overclocking and top end HEDT CPUs

 

A single 4+4 pin can do 384w om its minimum spec. You will kill the CPU and VRM before reaching those levels of powerdraw.

 

The extra 4 or extra 4+4 pin is there purely for marketing purposes.

I think you meant the extra 4 pin XD.... the 8 pin(4+4) is the norm 

 

According to what i researched IN 99.9% cases its PLACEBO. the 8(4+4) pin can deliver more than 300 watts to the CPU.  Just wnated to confirm

You get extra 4+4 pins on higher end boards.

 

Any extra 4 pin (4+4 or just 4) connector is completely unneccasary if you have a single 4+4 pin.

Well as i said:

Which is the minimum spec on the connector. There is a higher spec variant that does more than 450w.

Its purely for marketing reasons, as it does nothing.
