Excellent power supply for an eGPU with RTX 5080

This power supply has been working perfectly with my eGPU setup using an RTX 5080. It's very quiet under normal load and completely silent most of the time thanks to the fanless (silent) mode. There is no coil whine at all, which was very important to me. The build quality feels solid, power delivery is stable, and overall it gives a lot of confidence when running a high-end GPU. A great choice for an eGPU setup where low noise is a priority.

Amazing PSU for 5090 owners!

Was in the market for a power supply to power my RTX 5090 and 7800x3D and this was one of the most recommended to me by other PC enthusiasts. I don't have a super power hungry build that warrants more than ~1000 watts so when I saw this on sale, I knew it was a top contender for my build. Installation was really simple and the wires aren't extremely thick like other PSUs so wire management is simple. One thing you do have to watch out for is that it only comes with ONE(1) "normal" PCIE GPU cable aside from the 12V-2x6 cable. If you have a card that needs more than 2, I'd definitely look into contacting MSI to get another one at no cost. All in all, this power supply has been amazing so far. No coil whine, runs quiet, and 5090 works perfectly fine under extreme load. 9/10, would definitely recommend!
