Hello,

I am a noob to eGPU world, After searching for days, I found that the best option available for me (in India) is AKiTio Node and vega 64, which I ordered and I will get it within a week.

I have MacBook Pro (15-inch, 2016) with touchbar, running macOS 10.15.3, and I want to use eGPU for both MacOS (mainly fcp and Civ VI) and Windows for gaming (not installed yet, will need guidance).

While reading, I found that the default power supply of AKiTio Node is only 400W which won't b enough for vega 64. In multiple posts, I read that people are preferring corsair SF600 for this, but the issue is, in India price of that psu on amazon is 220USD, which I can not spend.

Can you suggest me, the specification of psu, which is compatible with AKiTio Node so that I can find psu under my budget? I can spend 100USD for that.

@faizyzaidy, try your setup before purchasing a PSU. It might just work, but the Node PSU is horrible as is. PSU prices are hiked everywhere. On top of that SFX ones are more expensive. Consider looking at used market/eBay.

Undervolting will help significantly if there’s no choice.

@mac_editor, should I go with semi-modular or fully modular is the only option.

@faizyzaidy, I had a similar experience with my 1080Ti and Akitio Node build.  Both Vega64 and 1080Ti are listed are requiring an upgraded 500W PS by the AKiTiO Node support doc: https://www.akitio.com/information-center/node-gpu-compatibility

 

I'm able to use the stock 400W PS of my Node without any issues tho.  And my particular 1080Ti (MSI Gaming X) draws much more power than an average 1080Ti.  It has a nearly identical power draw to a stock Vega64 per TechPowerUp.com (305W peak vs 303W peak).  However, some Vega64 cards have additional "Turbo" BIOS settings that will draw even more power; up to 360W.  It's probably best to avoid Turbo BIOS settings when using the Node's stock 400W PS. 

 

FWIW, I've never overclocked my MSI Gaming X 1080Ti beyond the MSI default factory setting.  It's about 8% faster than a 1080Ti FE which is fast enough for me.  If I attempted to overlock it further I'd probably end up having to upgrade the Node PS to 500W to maintain stability.  Not worth it IMO.  I agree with @mac_editor's suggestion to try it stock before purchasing a 500W PS.

@faizyzaidy, hi!

Have you founded a good and "not so expensive" PSU for the Node?

I'm in the same situation, I'm considering to upgrade the PSU of the node.

For now i've inside an old GTX 980 ti, but i'd like to change it with a more power hungry AMD card (i use it on a macpro mid 2018)

Thanks!
