The Microcenter nearby has EVGA GTX 1080 Classifieds in stock, the 08G-P4-6386-KR model, selling for $699.99, and I think I'm going to run over and get a couple to replace the EVGA GTX 980SC's I had for quite a while now.  I've been running them with a 1000 watt PSU and I've got a watt meter on the computer and I've never seen it show more than about 800-840 watts even when under load running both of my 28" 4K monitors.  The EVGA watt 'calculator' says that I should probably have a 1050-1200 watt PSU, but I don't think the 1080 Classifieds would pull that much more wattage than the cards I've got now, especially since I run them at stock settings all the time. Does anyone think I would have a problem running them on the PSU that i've got?

Gigabyte TRX40 Aorus Pro WiFi Amd sTRX4 ATX MB, AMD Ryzen 9 Threadripper 3960x, EVGA RTX 3090 FTW3 ULTRA HYBRID GAMING, 24G-P5-3988-KR, twin - 28" 3840 x 2160 Monitors, Samsung 980 Pro 2TB, M2 NVME SSD for OS, 3x2 TB  Samsung 980 Pro SSD's for storage, Samsung SH-203 SATA DVD Drive, Coolermaster 1000 Watt PSU, Win 11 Pro, Coolermaster HAF 932 Advanced case.

    Your PSU is more than enough to run 1080 Classified in SLI.

    Coolermaster 1000 Watt PSU, more than enough for an SLI setup.

    Unless it's an uncharacteristically crappy PSU which could cause reboots and or coil whine (hey it can happen) but as for the mathematics, more than solid.

    Edit: and the manufacturers reputation is good as well, not knocking Coolermaster at all. just interjecting there is a worse case possibility.
