Sonnet 550 with Vega 64?
I know Sonnet 550 is supposedly not approved by Sonnet to run a Vega 64, but it's what I have at the moment and I'm not really sure if I want to spend $120 for a new PSU (enermax 650) just to have the 550W PSU sitting in the closet or $300 for Razer Core X and trying to sell the Sonnet 550 which probably won't sell well on the used market.
Has anyone tried running Vega 64 with the 550W PSU? Benchmarks suggest that Sapphire Vega 64 at absolute peak draws 421W ( https://www.tomshardware.com/reviews/sapphire-rx-vega-64-nitro,5388-6.html) and with 87W to Macbook, it would draw ~500W at absolute peak. Since the 550 PSU is 80plus gold, the minimum efficiency is 87% which is 478W and I was thinking if I can disable the power delivery from the Sonnet to Macbook by plugging in the Macbook's charging cable on the other side?
Any suggestions or ideas are welcome. Cheers!
I ran my Vega FE/LC with the Sonnet BB550 with OEM PSU for a while.
You have zero head-room with it even without PD.
So you will get occasional crash due to insufficient power.
I’d say I was able to use it about 95% stable.
You can unde-volt the Vega, and it might help.
But really you would want to replace the OEM PSU to be sure.
I didn’t like the enermax, so I ended up with using full-size ATX PSU, sitting outside of the Sonnet.
You can get the better PSU for cheaper that way.
