Do I need to plug in all CPU power connector?

Distinguished. You do not have to plug that extra 4 pin CPU power connector on the board. The 8 pin is more than enough for running the system. You’re totally fine without it.

Do I need to connect both 8 pin and 4 pin CPU power?

You don’t actually NEED both connectors plugged in. Usually the motherboard functions perfectly with just the 8-pin connected. You’d have to have a very high end CPU or a very overclocked CPU in order to actually NEED both connections populated.

Does the CPU need 8 pin power?

From experience, it suffices to install the 8 pin connector on the left. The right 4-pin-connector is basically a redundancy that the CPU may draw upon under extreme load most likely only relevant when you do extreme overclocking.

Can 8 pin CPU plug into 4-pin?

Our power supply units (PSUs) use an 8-pin EPS12v CPU cable that can be split into two 4-pin connectors. If you want to connect our PSU into a 4-pin EPS motherboard port, simply pull the two halves of the connector apart and connect one half into the motherboard port.

Is CPU power required?

Standard CPUs use between 65 and 85 watts, while quad-core processors range from 95 to 140 watts. The maximum needed is 30 watts for a short time when booting the system; you should allow a safety buffer for this when estimating maximum power load capacity.

Will a 4-pin CPU connector work in a 8-pin socket?

It is entirely possible to just plug the 4-pin connector in the 8-pin slot. It won’t damage anything, but the motherboard will detect the difference and either not start up at all, or run in a VERY restricted mode.

Will a 4-pin cpu connector work in a 8 pin socket?

Does the cpu need its own power?

A little of both actually. The cpu receives power from the m/b, but the m/b also requires either a 4 or 8 pin connector from the psu.

How many watts does a Ryzen 9 3900X use?

The Ryzen 9 3900X pulls 142W at stock settings, and that increases to 168W when we engage the new “Auto OC” and Precision Boost Overdrive features.

What power supply do I need for Ryzen 9 3900X and RTX 3080?

3900x is rated at 105W, 3080 is rated at 320W power draw. Toss in 50W for Motherboard and Misc, another 50W for DDR Memory, and a 20\% buffer -> 1.2*(105+320+50+50) -> 630W. You’d be good with a 650W Supply IMO, but it wouldn’t hurt to go 750W.

Can you use a 4 pin CPU power connector?

How good is a single 8 pin power connector for Ryzen?

The Ryzen processors don’t use a lot of power, even when overclocked by average Joe, a single 8 pin cpu connector is more than enough to power it and have room to spare. Now that I have everything hooked up, minus the 4 pin. It boots up fine, then freezes randomly if I do anything at all, like brows the web or download something.

Do I need to connect both CPU connectors to avoid freeze?

So, at least for Ryzen 3000, I think you need to connect both CPU connectors to avoid Windows 10 freeze. Also, the MSI x570 A PRO manual (page 32) explicitly says « Important : Make sure that all the power cables are securely connected to a proper ATX power supply to ensure stable operation of the motherboard » on the Power Connectors page

Can I plug in an 8-pin CPU to a 4-pin PSU?

You can plug in the 8-pin CPU connector you have, and hope it is enough. Although I see in another post by you that you planned on buying a 3900X or 3950X, so in that case I would be very surprised if it powered on. If it doesn’t power on, you’ll likely have to buy another PSU that comes with the additional 4-pin CPU connector.

How many pins are there in a CPU power connector?

Nowadays, we even have 8+4 pin, 8+8 or more CPU power connector on the motherboard. By design, each pin can sustain up to 7 to 8A. Figure 2. is the pin definition of CPU power connection.
