Question new power supply with older computer

[velocci]

Hi all, I just bought a Corsair RM650x power supply (fully modular) for my old Lenovo M90p (5498-RW8) PC. the cable that plugs into the motherboard is different and the cable for the CPU is 6pin whereas my motherboard needs a 4 pin. so the motherboard that came with my PC is too old for this new power supply. do you know if I can buy older cables for this PSU that will work with my motherboard?

 

[doolittle]

yes you need an adapter like this it will plug into your 8-pin +12v and give you the 2x4 pin, use one for your board.

Although, double check the connector again I had thought you didn't need it for that PSU and should already be 2x4 pin that is connected together, you may just need to fiddle with it a bit to get them separated.

If your cable is a 6-pin its for a GPU not for a CPU. If it's an 8-pin you can cut it in half(do not recommend) or use an adapter
Edit: Also the mobo in your PC and the PSU connector for the motherboard should be compatible because you should have 1156 motherboard

not too old, OEM's just use proprietary plugs cause screw the consumer. You can buy adapters.

ok i'm good with the 4pin CPU plug. I just had to split it in half. But the 24pin plug doesn't go in for sure. the plug that came with the PSU is also 24 pin, but the configuration is different than that of the motherboard. I need some kind of adapter or replacement cable. Or it could be proprietary. how do I find out?

The good guy legit recommended not to cut it in half.
You should've waited a little and bought an adapter instead or something

He didn't cut it, some psus have the option to split it, but some dont and can be cut(that's why i said it because i didn't check if he had an option to split), and i think his can be split.

Well yeah my power supply has that option but not sure if the rm650x has it or not.

I checked it's a 4pin+4pin EPS12V connector

 

[iMatty]

That's good!

 

[velocci]

RabbitSK, That link doesn't work.

Yes its a 4+4, snapped together. I would never cut it.

How many pins does the connector on the mobo have. If it has 14, i think this is the right adapter, if no, google 24pin to lenovo (insert number)pin

 

[velocci]

the mobo has 24pins.

 

[RabbitSK]

If mobo has 24pins psu connector should fit, can you take a picture?

 

[velocci]

it doesn't. the circl and square holes don't match. i'll take a picture anyways.

anyone have any thoughts on this?

 

[velocci]

update: I don't know what kind of drugs I was on the other day, but that 24pin connector does plug into the motherboard. so everything is fine. The reason why I bought this new PSU is because is because the Lenovo PC only has a 280 watt PSU and I was playing movies on it using plex and the PC would reboot many times throughout the movie. I'm pretty sure the problem was that the PSU was too weak for it. I'm now playing a movie to see if the PC reboots with this new PSU. any predictions?

 

[velocci]

crap!! the PC is still rebooting on its own. anyone know what else could be causing this?

So you go the power supply because the computer was rebooting? When does it reboot and how exactly? Did you add/change anything in the system before it started doing this?

 

[velocci]

after swapping out parts with this PC and my son's PC, i see that the PC only reboots when using my 1050Ti video card and Plex. if I use my son's 1060 video card, its fine. if I use kodi with the 1050Ti video card, it doesn't reboot. only when using 1050Ti and plex. someone said the 1050Ti card is pulling too much power from the motherboard, but then why doesn't it reboot when using kodi?
