Hi, @BarbarySheep, not sure what exactly your problem is but you can refer to below 2 photos.

The SF600 just sits inside using some blu-tack.

I went ahead and did this upgrade. I noticed that the PSU itself can get pretty warm, perhaps 30c? I'd assume it could get hotter than this; doesn't blu-tack getting hot make it less sticky? I'm thinking of 3D printing out a cover or something to hold it down (that can be screwed in the old PSU holder holes)...

Just putting it out there: from first glance it looks like the EVGA SuperNOVA 550GM would also be a suitable replacement (socket, switch and SFX with fan on the mesh side); it's cheaper than the SF600. It's also fanless under low loads ( ). Of course it's 550W but that shouldn't be noticeable. Fans apparently don't turn on unless >=30% load so you probably will only hear it on full GPU loads on pretty high end cards (in theory a full load average 2070, it should be fine)... Not trying to sell snake oil so YMMV.

I will remove the fan bracket. I still have two questions but my Core X hasn't arrived yet so could you please help me with them?

thanks everyone for the excellent information about alternative power supplies and case fans.

my stock Razer Core X with an MSI RX Vega 64 inside has been driving me slightly mad with fan noise.

today i finally found the time to install a Corsair SF750 Platinum power supply and a Noctua NF-A12x25-FLX fan, what a relief!

for anyone planning to do the upgrade, i found that thick double-sided tape (about 2mm thick) works really well for mounting the power supply.

Anyone know if the Silverstone Nightjar NJ450 will fix in the Core X Chroma? I'd love to go fanless on the PSU, and the dimensions are listed as: 130 mm (W) x 63.5 mm (H) x 125 mm (D)

Not sure which is which in the early post because he calls them all depth. Would this fit?

@zorn_ It looks like it might fit. Compare dimensions of NJ450 (SFX-L) with standard ATX power supply (page 51). All the dimensions of the NJ450 are less than those of the original power supply.

140 -> 130 mm (W) 86 -> 63.5 mm (H) 150 -> 125 mm (D)

@zorn_

The first thing to remember is that the power supply is fitted vertically in the Core X not horizontally so the dimensions are something like:-

63.5mm wide, 130mm high and 125 deep so it will easily fit but you will need to cut a hole for the power supply as it's higher up than the existing PSU. I would also ask how you are planning to extract the excess heat from the case as there won't be any fans to move air from that part of the case and from my past experience of that PSU it loves to generate excess heat.

Looking at the price on Amazon (UK) the Corsair SF750 is about 2/3rds of the price and it's silent on loads up to about 300w (the fan doesn't go on unless I'm gaming). It also has its plug only slightly below where the core X's original power supply is so you can easily get the corsair power supply to fit using blutack or velcro sitting underneath the PSU.

So personally I really wouldn't recommend the Nightjar PSU - unless you already own it the corsair SF600 and SF750's are equally as silent, easier to fit and cheaper (at least where I live).

Couple questions:  Just got the SF600 PSU, and I'm not sure how to secure it in place. Plugging in the power cord is really hard since it just slides around freely inside. Also, I mounted a 140mm fan in the front, but now there is no room to put the front cover on and it looks kind of stupid. Is it really important to have a fan inside there other than the GPU? I don't like how unfinished it looks with a fan hanging out the front.

@zorn_ Add some metal bits (plates or angled pieces or whatever), make same holes, insert screws into holes? Use different sized fans (different diameter and thickness)? I don't have an enclosure to look at for measurements so I don't know if there's a solution.

I noticed with my new Razer Core X that even when my mini is in sleep mode the PSU fan is still going which is an annoyance. Does anyone know if the Corsair SF750 sits in zero RPM mode when the Mac mini is asleep? I read in another thread on here ( https://egpu.io/forums/psu-cables/sf600-fan-running-in-sleep-mode/) that the SF600 has the fans running in sleep even though it's zero rpm mode.

Just want to make sure before I get a SF750 that I don't have this issue.

Today my Razer X, PowerColor Red Devil 5700 XT, the Corsair SF600 (Platinum Edition, not Gold) and the Noctua Fan arrived. The installation was done in 45 minutes. Works perfect now. No problems with sleep mode: The whole Razer X "sleeps", no fan is running, the LED of the GPU turns off too.

This video shows a cheaper mod to get the same effect:

I would not recommend that.
He lost the warranty. It will hardly be possible to unsolder the wires of the PSU fan so that Razer will not see the modifications.

I think the odds are positive, spending 125 EUR  just to avoid risking losing the warranty on a 300 EUR device, I'd rather take the chance.
