[SOLVED] Molex connector problem ?

[ferguson1951]

Hello everybody.
I am writing from Italy.
I have an ATX PSU with various output cables including a 4-pin Molex which I think is for the mobo power supply.
But my micro ATX mobo has an 8-pin connector.
How do I go about solving this problem ?
Your help will be much appreciated.
Thanks a lot and best regards

Mobo: Asus Prime B364m k
PSU: Delta Electronics 350 w GPS-350EB-200 B
ram: Samsung DDR4 4Gb.
GPU PCIE card : (arriving) ASUS EN 8400 GS SCHEDA GRAFICA VIDEO SILENT PCI EXPRESS 512 MB GPU GRAPHICS CARD
CPU: Intel i5 8500
Case: HP ProDesk 400 G3 MT

Keep in mind - pc should beep even without ram.
If it doesn't, then there's some other problem also.

 

[ferguson1951]

Then there is another problem. I'm getting tired of all this. Look, I wait for the Ram and then take the PC to the technician's.

 

[SkyNetRising]

That's what you get with used parts.
Basically every part is a suspect then.

 

[ferguson1951]

No, the only used part is the Ram

 

[SkyNetRising]

Cpu didn't seem too fresh either.

 

[--SID--]

No, the only used part is the Ram

i5-8500 is over 5 years old. If you bought that new you're fooled by the seller. And if it was new it's in very bad shape like I said before.

 

[ferguson1951]

I bought it used, it was tested and found OK

 

[ferguson1951]

Hello. Ram arrived, fitted it: no luck.. Now the problem could be either the CPU or the Mobo but I treated the Mobo always right, discharging my static electricity by touching the heater. Still a mistery.
I bought another CPU

 

[--SID--]

Ram arrived, fitted it: no luck.

If it fit does not mean it will work. What's the brand and model of the RAM?

 

[ferguson1951]

Kingston ValueRAM 8 Gb

 

[ferguson1951]

Bingo!!! The new CPU arrived. It's a i3 9100F and it works. The beeper beeped.Now I will pick a fight with the seller of the previous CPU.
Now the build looks like this:


Mobo: Asus Prime B364m k
PSU: Tecnoware (Italian) 650W
ram: Kingston ValueRAM DDR4 8Gb
GPU PCIE card : ASUS EN 8400 GS SCHEDA GRAFICA VIDEO SILENT PCI EXPRESS (not tried yet) 512 MB GPU GRAPHICS CARD
CPU: Intel i3 9100F
Case: HP ProDesk 400 G3 MT

Words fail me to thank you all for your VITAL help.

Great.
Now just get a decent standard ATX/mATX case with proper standoffs installed.
(not that proprietary Dell/HP thing, that probably was shorting out your motherboard)

 

[ferguson1951]

Let me just remind you that I carefully insulated the Mobo from the case with insulating tape where the Mobo touched the case.

I wouldn't trust that.
Motherboard still has to be securely installed in pc case.

Keep in mind - shorts (resulting from using improper pc case) can kill your working components.
Then you'll be back at square one - dealing with same issues again.

Quite possible, this was the reason your previous cpu got killed.

Then let us do one thing: you look up Amazon and then choose one case that suits my needs and send me the info.

[ferguson1951]

Thank you SID, I like that case, I bought it

 

[ferguson1951]

Hello, the case will arrive within about 10 days more

 

[ferguson1951]

Hello, the case arrived today, I will let you know when I am ready to proceed. Thanks a lot

 

[ferguson1951]

Hello buddies,
Here are two pictures: standoffs are already built-in in the case and some of the screws that come with the case I don't know what for. I hope I can rely on your good offices.

See post above.

Four standoffs fits the mobo.

Channel fan has 3 pins but mobo connector has four.

Below showing you some connectors that come with the case.

Make sure every installed stand-off has a corresponding hole in motherboard.
Any stand-off without corresponding hole will create a short.
Your motherboard requires 6 stand-offs.

Four standoffs fits the mobo.

Motherboard needs 6.

Channel fan has 3 pins but mobo connector has four.

You can use a 3 pin fan on a 4 pin header. You need to set the header to DC mode in the motherboard BIOS.

Below showing you some connectors that come with the case.

Check the manual of the motherboard where to connect those connectors on the motherboard.
