Laitoin myön Seasonicille tarkan viankuvauksen aiheesta ja kysyin heidän mielipidettään. Sainkin jo vastauksen:
Thank you for contacting Seasonic.
Based on your description, we would say that the PSU safety are kicking in due to the fact that 3080 got spikes under load (Upto easily 500W - you cannot see them with a socket meter as they are too fast to be caught by them) and if they are too high, then such issue may happen. This is why a 750W minimum is recommended for such cards and on our side, we can even recommend a 850W to have headroom. Most likely, your PSU is OK but the spikes of the 3080 are too heavy for it.
Any other question, please let us know.
Thank you.
Eli alkaa tämä homma näyttämään nyt melko varmalta. Uuden virtalähteen saanee ensi viikolla niin sitten näkee, korjaantuuko sillä. Onnea teille jotka olette ottaneet hieman enemmän pelivaraa virtalähteenne kanssa
