Now after reading this. Is there something you guys can recommend me to make the Razer Core X quieter? Recommendations for fans and psu replacements?

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

If you really want a silent system, and if you are not planning to move the eGPU often, you should consider placing a PSU externally.

What you see here is a Sonnet 550 with the OEM PSU removed and hooked up to EVGA 850W Titanium. The 550 host a Vega FE/LC, OC’ed to 1700/1045.

The PSU runs at 0db while the GPU is at 100%. Between the better PSU and other non-warranty-voiding tweaks I made, the whole system stays under 45db from where I sit during gaming. (I play No Man’s Sky, and it eats GPU for breakfast).

No reason to get 650 if you plan to replace the PSU.

If anyone is amenable to downgrading from 650 W to 600 W PSU, a fan less silent PSU is an option.  A Seasonic 80+ Titanium PSU has no fan and should be fine with the 120 mm case fan in Core X.

This is exactly what I'm thinking about doing to the Core X Chroma. Have you done the replacement? Curious if this specific PSU will fit inside. Thanks!

For Razer Core X, the recommended option is Corsair SF series. Seasonic Prime Titanium series (or 1000W Platinum and Gold) with 170mm depth will not fit in Core X because the PSU will bump into the 24pin connector on the PCB. I have Core X with Seasonic Prime Ultra Titanium 1000W and I can only leave the PSU outside the enclosure.

On the other hand, the new Chroma version most likely is possible to have Seasonic ones inside because the bundled PSU is larger than the old one and the 24pin connector has been moved away from the IO side.

If you want to experiment with Seasonic, personally I would recommend go with Seasonic Prime Ultra Titanium (similar price)/Platinum (tiny difference in efficiency but higher quality output)/Gold (lower price) instead. Higher wattage combines with low load fanless mode and silent FDB fan means 0db in the case of eGPU. Leaving the PSU at 50% load gives you peak efficiency with low temperature. Prime Ultra series don't have in line capacitors on the cable which makes the cable more flexible compare to Prime series.
