5080 power supply question

[HockeyJon]

Hey guys,

I ended up RMAing my 7900XTX to MSI and they told me they can't send another over since they discontinued it and offered to send a 5080 instead, which I accepted. Just wanted to get some opinions on the power supply side. I'm currently running an MSI MEG 850W unit that has no native 12V-2x6 support. I'm already leery about the 12V-2x6 connector given its history (although less with the 5080 than a 5090 since the 5090 is redlining the thing), but it's the only option with the 5080. I had two questions I wanted people's opinions on:

1) I understand it's technically fine to use the adaptor the card will ship with to plug the connector into the 8-pin cables native to the PSU, but would it be better to have a PSU with native 12V-2x6 support considering how fickle this connector seems to be?

2) Although the 850W PSU should be well within the power window of my system, if I do upgrade to one with native 12V-2x6 support, would it be worth it to get a 1000W unit just to protect against transient spikes and things like that, or just stick with 850W?

Thanks!

1) The adapter supplied with the card will be fine with the PSU you stated. No it woukd not perform better necessarily if the PSU supported 12V-2x6.
2) Your PSU is perfectly fine and a 1000W would not make a difference. That is a decent quality PSU that is not known for issues or premature failure. Everything you have will be fine if you use the adapter supplied with the card. Avoid this party adapters and you will be fine.

Yeah I still use 850watts I have a backup one even with Cable Mod Cable own 1000 watt MSI but refuse to use it. Came free with my MSI Suprim card. I used s 450 watt for 10 years once was a Generic PSU that came with my Raid Max case then it died.
