Power supply on my Sonnet eGFX 350 died, so I took the opportunity to upgrade it to a 650W 80 Plus Gold modular PSU. Easy replacement, but I documented the process in pics for anyone that's interested. It's a standard SFX form factor power supply. I'm still running only an AMD RX 580 but glad to know I can now throw pretty much anything in there and it will power it.

@macsare1, OMG - I've had on order for 2 months a 650W SFX power supply (Seasonic SGX Focus) to replace my BreakAway Box 350w power supply. The other day I noticed NewEgg had the Fractal 650 SFX power supply in stock so I cancelled the first order and placed an order for the exact same supply you installed. So glad to hear it works. I also have a RX580 in my BreakAway Box but wanted to upgrade the ps with the intent to upgrade my video card in the future. How's the noise with the new supply? Silent? Thanks for documenting your upgrade.

I finally received my Fractal 650 SFX-L power supply and got it installed. As you said, an easy replacement. Although this power supply is a SFX-L vs a SFX it fits fine, just a little longer. It's also dead quiet.
