    Great quality. But fails to deliver basic cables for a modern build. Had to buy extra overpriced cables just to be able to run my GPU, because their cables provided were not “recommended”

    So far, so good. The only downside to this model, is the lack of PCI-E cables. Solid power delivery and stable. If you need more PCI-E cables though, look to another PSU or get a set of custom cables from Corsair.

  • Powering a hybrid rig.

    I bought this PSU because I had a unique setup where I turned a Dell Precision T5810 into a gaming rig by installing an RTX 3080 FTW3 Ultra GPU. Since Dell uses proprietary power connections, I couldn't just upgrade, I had to add on. So I plugged in the PSU and added a jumper to the PSU. I haven't been able to fully utilize the PSU so I can't give a higher score. Not to mention that the modular part is a little confusing. The GPU/CPU connections and their titles are in odd places and the directions didn't help much. But it does say more than I need right now, so it's still working beautifully.

    Computer has been running for a few months now and no problems. I like that you only use the cables you need which makes it easy to organize them and allows better air flow.

    When all of the power supplies are out of stock, Best Buy was the only store that had 2 remaining. 850W is more than required but it ensures a buffer, in capacity, of 20%.
