One PCI-E cable in 2025?!?!?! Yikes!
Bestbuy lists this as having 3 pci-e 6+2 pin cables but it only comes with one......in this day and age that's insane. If you want to join the social experiment of burning your house down with 12vhpwr cables feel free and buy this. Most people buying a 1000w power supply will need 2 or 3 pci-e cables. I returned mine after realizing this, thankfully the people in store were nice and did not bother me about the return. Seems like a nice power supply, but it is useless to me since my rx7900xt gpu requires two pci-e cables. I think bestbuy is generically including the 12vhpwr cables in their count, but a picture of the box on the website would fix this issue of inaccuracy of the description. I contacted MSI customer support a day before returning it, so far they haven't responded to me. I gave up and exchanged it for a corsair psu that came with a plethora of cables. Oh well I guess

Great psu
Works great on my 4080 super build. I’m hoping that 1000w is enough for a 4090 or a 5090 in the future
