Hello,

Someting I don’t understand is when I see a test of power consuption of the Asus Vega 64 I see on Tom’Hardware test a 280W in their torture testing...

But when I look at the user experience I ses that people say that we need a 600W PSU...

Not very understandable 🙂

Some clarification by our experts here ?

Thanx in adavance

@igerard Vega 64 suffers from peak currents (short bursts of extremely high power draw) which can be difficult to capture in testing. I have seen it myself though. The minimum recommendation is 650W actually. Undervolting can help significantly (mine consumes about 210W max without those peak currents so far).

Well, I received the card today and just tested it, ran well for some time and the PSU gave up 🙂

The bench are good though, happy with that already.

I will have to upgrade the PSU or buy a Razer Core X , didn't decide yet, good also to have two eGPUs.

Thank you for the reply.

During Ungine Valley the temp went well, around 50° with 3440x1440 Ultra 4xAA

BTW under-volting ? How to do that ?
