The 790 appears to use a standard motherboard so an off-the-shelf power supply would be a good call for an upgrade. Don't look at any old power supply, consider units that are better than the Corsair VS since this is for a gaming PC.

Yes, any Corsair power supply is compatible with an RX 580

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad
