Help on PC building

Hi Expert,

Good Day.

I need help in building pc, I am using motherboard ROG STRIX Z370-F GAMING. I did some googling but still afraid.

1) I have a PSU which have a 4 pins x2 CPU connecter but on my motherboard only have 8 pins EATX12V, so it's ok if plug the 4 pins x2 CPU connecter to 8 pins EATX12V?

2) I notice my motherboard dont have 3 pin for my casing fan, like to check is it all right to plug to 4 pin instead?

3) I have a 4 pins AIO_PUMP which I would like to check is this pins suitable for 3 pins fan? Because I have 3 fan needed which is not enough.

4) For Coolermaster MasterAir MA610P I not sure if needed to connect to CPU_OPT or not, also not sure if it can use for 3 pin fan.

Appreciate if any expert can assist me on.

Thanks!

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

1) Yes.  The connectors will be keyed so they only fit one way.

2) Yes.

3) This is probably okay and, even if it doesn't work, probably won't break anything.

4) The CPU_OPT header is an additional fan connection.  Feel free to use it if you need to.  it's functionally identical to a CPU_FAN header.

The AIO Pump is for water cooling.  I am sure you could use the header.
Fan Header info
See the manual from 1-15 Above.

And everything else is as stated by Paul. The 4x2 should be fine if it fits.  As stated should be keyed.
The only problem is if the PSU is not adequate.  You do not specify what your other parts are on this system.

If you are still unsure, you can post the rest of your equipment and we can follow up.

the easiest would be a 4-pin to 8-pin adaptercable :  https://www.ebay.com/b/4-to-8-Pin-12V-Computer-Power-Cables-and-Connectors/182097/bn_864401     0.99$

what power rating does your PS have - or post the model - can it power your board + cards?

Hi Expert,

Thank you for the help.

I am using Toughpower Grand RGB 750W power supply.

Let said if I plug in any wrong connector to the motherboard what will happen and will it damage the hardware?

Thanks

If you plug them in incorrectly most likely you would either have to FORCE the connectors in wrong on the motherboard or break them.  Most of the time the connectors are keyed.  They have to be.  As the motherboard connectors are also keyed.  round vs angular connectors and they can be round on one corner and the other corner angled.  The connectors should be able to go in fairly smooth and easily without a significant amount of force.

If you do force the wrong connector into any certain spot, you can cause damage to the motherboard or any device that is incorrectly connected.  Also note that any devices connected to that chain, memory, cpu hard drive could potentially fail too depending on what the motherboard or any device you connect incorrectly does.  Hard to say.  But yes, if incorrectly plugged in could damage the hardware.

normally the power is ok, but what video card do you install?  how much power does it take?

Thanks for all the support, I went back to the shop and get them fixed, I almost damage it, luckily was all fine in the end. Really need hardware knowledge to build from start, by reading and video not good enough.
