Power Supply Limitations

Users discuss the power supply requirements, voltage, current, and wattage limitations for high-performance devices like GPUs, expressing concerns about insufficient power bricks and barrel plugs while suggesting alternatives such as higher voltage PSUs or downvolting.

true. at this prices they might as well include a power brick and take responsibility of the current carrying path from the wall to the die.

Just get the official power supply then.

Seems like GPUs need more voltage. Something like 120V would be more appropriate.

I think you can get a 5060 and simply down volt it some, you'll get more or less the same performance while reducing power draw sensibly.

Probably a DC-DC adapter, bypassing the power brick entirely.

The official power supply has 2A.

Weird that mains power can’t go above 5 - some messed up design there!

I'm personally concerned about the claimed 500W power - Surely that isn't enough?

Same here, but only if it doesn't need > 3.5 amp PSU.

Most switching power supplies won’t care
