Hi,
I had the same issue, all mobo lights on but pc wont startup,
so i tried another power supply (have it from my previous sys), and my pc boot up normal and everything fine.
Hope this help .
I would guess is the PSU.
Did you experienced random crashes recently?
Both my OCZ and Thermaltake gave me very nice BSOD before dying.
Quality 750W PSU is easily enough.Would a Superflower Leadex Gold 750w be ok with the 2700X and Vega 64? Everythings running at stock atm
Quality 750W PSU is easily enough.
But for buying new PSU SuperFlower isn't the best choise if your interested in good warranty.
IIRC SuperFlower has 7 year warranty and who knows how RMA would go.
Superflower's website is pretty impervious for getting any info about support.
I think you now consider long warranty, and one which works without having PSU sent half way around the world and back as good thing.
