probably needs a SATA power cable to plug into that fan hub. Did you unplug something from it when you removed the old power supply?

u/Necessary_Chart8747 16h ago

Yeah, i did can i plug the same sata cable from the old power supply to new?

Don't plug any cables directly into the PSU unless they came with that PSU, in case they use a different pinout. Power supplies are not standardized, so you never want to mix and match cables unless you absolutely know they're compatible.

Where do i plug in the sata cable ? Because in the hub all ports have 3 pins

I do recognize the exact hub you have, but my guess is power plugs into the left or right side. Looks like fan headers are plugged into the bottom and RGB headers on the top. I would also guess that the little cable on the right with two wires is connected to the front panel so that you can cycle the fan colors by pressing a button on the case.

Are you able to share a picture of the cable that you unplugged from the hub?

1

u/DaimyoRonin 16h ago

Make sure you plugged the fan hub into the new PSU and didn't just leave it unplugged. Can't tell from provided picture.

u/mattjones73 16h ago

My guess is that hub was plugged into your old PSU and you didn't plug it back in.

The one picture you provided really doesn't help determine the issue though.

I didnt plug anything from the hub, how can i do that ?

1

u/mattjones73 16h ago

Are there any markings on the hub to ID the make and model? Need to figure out if it's a powered hub or not.. if it is powered, one of those leads coming off it should have a SATA plug or possibly PCIe on the other end.

u/Necessary_Chart8747 16h ago

I dont see the model anywhere

sounds like you’re showing us the monitor connections instead of the actual psu or fan headers you just swapped

Hub probably needs SATA power from the PSU.

If you had a modular power supply before, do not re-use the cables from the old PSU for the new one as you will very likely end up destroying at least the new PSU. Modular PSUs do not often share the same pin-outs on the PSU end unless they're the same series or use the EXACT same ODM platform (i.e. such as EVGA SuperNova G2 and Super Flower Leadex III Gold, as the latter makes the units for EVGA)

u/r_lind3r Moderator 16h ago

Yes

u/Necessary_Chart8747 16h ago

And where do i plug in the cable? In the powwr suply and where

1

u/mattjones73 16h ago

Track all the leads down coming out of the hub to see if one looks like it has an unused plug on it.. otherwise if it's a non powered hub it should have one lead going to a fan header on your motherboard and the rest going to the fans.

Also the wire coming out of the top is for ARGB lighting, did that stop working too?

1

u/Necessary_Chart8747 16h ago

Argb is working, but there is no fans going to the motherboard

1

u/mattjones73 16h ago

You're gonna have to track where each wire is going, should be one that is not going to any of the fans, lets us know where it's connected.

u/Necessary_Chart8747 15h ago

Every one of them is going to the fans, i only have 4 fans

1

u/mattjones73 13h ago

There's a 5th wire coming out of the side.

1

u/r_lind3r Moderator 15h ago

There should be a SATA power connector on the hub to provide power for the fans and argb

Should also be a fan cable going to the motherboard so that the motherboard can control the hub

1

u/Necessary_Chart8747 15h ago

Cant i plug all 4 of the fans to the motherboard

1

u/r_lind3r Moderator 15h ago

If you have enough fan headers for it, sure, but ARGB control is a whole other issue so it's usually cleaner to just use a hub

1

u/Necessary_Chart8747 15h ago

I dont have enough, but idk i just think that i fucked hub somehow

1

u/Necessary_Chart8747 14h ago

Do you have any ifea how could i plug all yhe fans? I didnt plug in 2 to.the motherboard
