Great (not just Good) PSU, for 6-8 GPU open-air mining rig?

[VirtualLarry]

Looking at six RX 570 cards (each with one 8-pin) to start with. (Ordered a 6-GPU open air frame.)

Was looking at Corsair RM1000x, and Seasonic Focus Plus Gold (I think that's the name) 1000W. Both are roughly $160, and have 6 or 8 PCI-E 6+2 pin connectors, are fully modular, and have 10-year warranties.

Any preference or reason I should get one over the other? I was kind of leaning towards the Seasonic, as there were some questionable reviews on the Corsair, and I think it's newer, but should I also consider EVGA G2/G3 or whatever their newest top-end consumer lineup with 10-year warranty is?

I've also already got an ABS (Newegg house brand), 1200W (or maybe it's 1050W) 80Plus Silver, it's an Enermax re-badge, which would probably work without spending extra money, but it's been sitting idle for maybe 5-6 years on my shelf. Heard that caps degrade faster when not in a live circuit. Plus, it's only "Silver" rated.

I think any of those would be a good unit, but I see a lot of the Corsair units being sold as refurbs, so that is a little concerning to me. Plus, I don't think they have a switch where you can turn the "hybrid fan" feature off, like the Seasonic and EVGA G2/G3 units have.

For Seasonic, you also have their Prime Platinum and their Prime Ultra Gold units, if you're looking for "great".

Another one to look at is the EVGA G1+. It's on sale for $129.99, and it has a 10 now 12 year warranty, and got a great review from JonnyGuru:

At that price, that's probably the one I would personally go with.

I'd go with a used pull HP or SuperMicro server power supply and a breakout board. You can get a pair of 1200w Gold rated Supermicro power supplies and a pair of breakout boards for $150. 2400w total and 24x 6 pin PCIe connectors. Or a single 920w platinum for $80ish which still gets you 12x 6 pin.
