@sunzoo888, I like your solution. But when buying, I plan to buy some module cables, because I expect that the cables that come with the power supply are too long and too hard, so I want to know PCI-E 8PIN or CPU 8PIN, which one is connected Small board

@yushi_pan, I am not sure I answer your question but the stock cables that came with the power supply were pretty good. I managed to fit them into the space between the Corsair and the existing frame inside the Core x with lots of space for ventilation. I would suggest getting the corsair and fitting in first, then you can see after whether you need to replace the cables.

This PSU also fits.  Right side up, things line up well, but the fan is on the wrong side.  Upside down, you have to do some clever stuff, and you don't have access to the power switch, but the fan is then on the correct side.  1000 watts.

Hey all, I'm new to this site/forum but I wanted to add some things from my side after I just modified my Razer Core X by replacing the PSU and the Fan.

So first I replaced the 120mm fan and then I realised that the PSU fan is making some noise so I was thinking of replacing the PSU and then on Friday evening the PSU basically blew up and switched off the power on 2 levels of my house 😀

I stripped everything out of the Razer Core X and opened up the PSU to see if I could find the problem. When I tried to switch on the PSU (knowing it would trip the Electricity main fuse) it made a blue flash from the switch area and that was that... Obviously I only tried this once and I do not recommend it to anyone as it is potentially dangerous if you don't understand exactly how things are working with electricity. So I decided to try to find a PSU that would fit 1-to-1 with the original and started an hour long search on Amazon.de

I measured dimensions of 150 x 140 x 86mm and checked the position of the Mains socket and On/Off switch as well as the cable protrusion. After some time i narrowed down my search to the Corsair TX650M with a price tag of 93 Euros. I wasn't really interested in getting a PSU with a higher power rating as I don't intend to buy anything better than the current GFX card in there which is a Gigabyte Aorus GTX 1080Ti with 11GB DDR5. So I ordered that PSU and it arrived the next day which was Saturday 13.11.2021). I started to look at fitting the PSU into the PSU space of the Core X case and found immediately that the On/Off switch was half covered by the case, so the original hole for the Mains socket and switch was not wide enough. This was the only issue and I proceeded to modify the hole using a Dremmel drill with a small cutter attachment and within 30 mins I had the hole done and looking pretty good (no unnecessary damage to the area around it).  I want to post this as a build with all the photos because My Razer Core X is now working perfectly and very quietly with the GTX 1080Ti inside it and with the new Corsair TX650M PSU and Noctua Fan.

I just have to find out now how I can post my build with photos on here...

I have a 2019 Macbook Pro 15" Core i9-9880H with 16GB RAM and 512GB SSD and I am using a Razer Core X as eGPU running a Gigabyte Aorus GTX 1080 Ti 11GB DDR5.

Thank you all for the great questions and information provided here. By following the information provided, I too installed the Corsair SF750 psu and Noctua NF-A12x25 PWM chromax. Black.swap, Premium Quiet Fan, 4-Pin (120mm, Black) to my Razer Core X. Now, Razer Core X is very very quiet. Below, I like to share some photos after my installation to anyone interested in this process.

I used velcro straps to stabilize corsair sf750 inside the egpu. As others have shared, this is a tiny psu. Thus, there will be a gap when you look at the egpu from the back outside. In order to reduce the amount of dust getting inside from that hole, I used the same velcro stap method from the inside to cover the hole. Next, from the back outside, I put the corsair logo sticker to further hide the empty space and make it look little nicer.

Below are few suggestions to anyone considering this approach:

1. Corsair PSU fan does not run when I am not gaming. Noctua 12v fan brings in lots of air to cool the interior of the egpu.

2. Do the cable management good inside the egpu so that you are not blocking the air your 120mm fan is bringing inside the egpu.

3. With this psu, one can install a 3 or 4 8 pin gpu. I currently have 2 idle 8pins connected to the psu.

4. Since the corsair psu is smaller than the original psu, I think one can install a wider gpu in the egpu.

I had never worked with a psu before. Thus, the entire process took a fun afternoon for me. The most interesting and perhaps the strangest thing to me was the testing process. After I installed and connected the corsair sf750 to the egpu's motherboard and the new Noctua fan, I wanted to make a test to see how the system works before moving on. When I powered on the Corsair SF750, the Noctua fan did not run. Not sure what is going on, I did the same test with the Razer's original PSU and another 120mm fan connected to the motherboard (not psu), the 120mm fan did not work again. Only when I connected the egpu to the laptop via the thunderbolt 3 cable, the system became alive. I do not understand the engineering logic here. But, I suggest anyone who is not tech savvy to pay attention to it.

Have fun and be safe.

@hattusili, If I recall the Razer Core X eGPU will never turn on unless it is connected to a computer. I had the same issue when I first got it and thought it was a bad unit.

 

Also, what graphics card are you using? I'm in the market for one and looking to see what works.

@403_forbidden_access, thanks for sharing your own experience! I have a 3 years old asus rtx 2080 and still loving it. I can play most games at medium settings on 4k with good fps. I heard gpu prices have been falling lately. Best wishes on your search.

I thought the side fan had to be 3 pin FLX noctua? Isnt PWM bad?
