[SOLVED] PSU RGB Fan 'Upgrade'

[FireFight]

Hello,

Hoping someone could offer a solution to an issue without saying ‘don’t do it’ 😊

I have recently purchased the Asus ROG Strix 850W PSU. The PSU has fantastic reviews but unfortunately is not supplied with an RGB fan, which somewhat spoils the aesthetics of the rest of my build.

The fan supplied with the PSU is an Everflow FB14025BH (135mm, 12V, 0.60A, Ball Bearing Fan) and connects to the PSU via a 3-pin connector with 1 x red 12V and 1 x black ground wire as shown in the picture linked below.

I’m hoping I can swap this fan to an RGB fan with some kind of connector or by modding the wiring of the RGB fan to make it work. I’d prefer not to cut any wires on the PSU.

I don’t need the fan to sync, just display rainbow colours similar to that on my EVGA RTX 3080 FTW3 Ultra.

Any suggestions would be much appreciated.

Thanks!

What do you mean the fan supplied with the PSU ? The fan is inside the PSU no ? I would just leave it

with most decent modern cases the correct way to install the power supply would be facing down towards a vent in the bottom of the case where it can pull in it's own cool outside air.
so the fan would be out of sight and LEDs on it pointless.

but the connector looks like a regular 3pin header, that's what most good PSUs use.
so swapping out with a 3 or 4pin fan should work fine.

Thanks, I should have mentioned I have the Thermaltake P3 open case so everything is open and obvious. I've a few fans that should be delivered soon to try out the best option.

Not really an option I'm considering at the moment. Thanks anyway.

The PSU is still mounted Fan down in that P3 case and there is a heat shield that sits above it...
What's the plan to make it's fan visible?

Anyways, you need to modify the PSU case to either add an rgb header to it (as well as making a custom rgb wiring harness to go to the rgb controller) or a hole to pass the rgb wiring thru.
In both options your warranty become null and void.

‘don’t do it’

This. A PSU fan is not something you should replace at all, unless it's totally dead. It's an integral part of the PSU design, replacing it you put a PSU at the risk of failing by thermal runaway. Not to mention that you'd void the warranty by doing so.

The PSU has fantastic reviews but unfortunately is not supplied with an RGB fan, which somewhat spoils the aesthetics of the rest of my build.

Why didn't you buy a PSU with RGB fan in the first place then ? And it's not really 'fantastic', it's just a Seasonic Focus with noisy DBB fan. For example there are RGB versions of Thermaltake GF1 and Super Flower Leadex III, both of which i'd pick over any Seasonic Focus based PSU if they're even a little bit cheaper or if i need a RGB PSU. I suggest you to return this ASUS PSU and get a RGB PSU instead.

Thanks, the case is mounted flat i.e. the tempered glass is at the top so the PSU is side-on and visible. I'll get a photo of it when I get home. I've thought about the pass-though hole thing. but first wanted to explore if there was anything I could do with the internal connection.

Voiding the warranty is not an issue. Unless my house burns down.

My choice of PSU was somewhat constrained by wanting 3 x 6+2 pin PCIe connectors for my 3080 and not having to daisy chain the 2 x 6+2 pin and also wanting 2 x 4+4 pin CPU connectors (even though they are wired in parallel) just because, and 18AWG with in-cable capacitors. I was struggling to find a PSU with those connections that aesthetically matched the rest of the PC, and would hoping replacing the fan would be relatively simple Buying another PSU is a possibility, I'll just use this for another build.

In that case you'd have to pay for aftermarket cables because i'm not aware of any RGB PSU with non-daisy-chained PCIe cables and changing the PSU fan is not an option. I'm not exactly sure but Thermaltake GF1 ARGB should use Corsair Type 4 pinout (because it's made by CWT which manufactures most of Corsair PSUs, they frequently use Type 4 pinout for non-Corsair PSUs) and Super Flower Leadex III ARGB should be compatible with EVGA G2/G3 cables (because they were essentially modified Super Flower Leadex II). So after, and if you get these aftermarket cables, check the pinout with the DMM first.

PSU mounting position.

I need it to match the rest of the unicorn jizm

It looks like you're already using cable extensions for some reason, so why bother about non-split PCIe cables then ? But i'd advice to get rid of extensions and to buy an aftermarket cable kit instead anyway.

Well, I can honestly say I've never seen one sitting flat and since I was very interested in this case, and its big brother, I looked at a lot of pics of them. I wanted to wall mount my pc. LoL
