At 500W+ maybe the GPU should have it's own dedicated power supply with it's own power cable. And then the GPU manufacturer could optimize the voltages and amps since they control the whole power chain. You could have some standardization, a simple power negotiation protocol "I can supply 500W at 24V or 48V" and a standard (big) connector. A long time ago the display was powered from the main unit, but we moved passed that and now displays have their own power cable.

Well, it didn't go that well [last time around](http://www.x86-secret.com/pics/divers/v56k/finalv5-6000.jpg http://www.x86-secret.com/pics/divers/v56k/finalv5-6000.jpg).

500W is going to be one hell of a wall wart.

  Eh not really, you just need to get two of these and connect the sync pins together: https://hdplex.com/hdplex-fanless-250w-gan-aio-atx-psu.html https://hdplex.com/hdplex-fanless-250w-gan-aio-atx-psu.html Way smaller than SFX PSUs and "gaming" laptop power bricks.

    That's a cool capability and I didn't read deeply enough when I saw the new GAN charger come out to notice that. I haven't used it but from the outside it all appears very thoughtfully and competently engineered. His products have some of the highest TDP support (passive cases and his PSUs) on the passive HTPC market and the hifi aesthetic is great. I'd love to get an H5 or an H1 (although for a HTPC it'd be nice to have the H1.SODD - the H1.TODD doesn't look nearly as nice imo), don't really need it but the cat would love it. Streacom does some interesting stuff too (like the DB4 cube case). Not quite as high TDPs and I don't like their body/fin aesthetic as much, but the DB4 is cool. And Akasa as well, love the galactico design. Mini-box is the company that originated the picoPSU design and they do a fair bit of other miniature-computing stuff as well, including for the embedded automotive market. They have 18650 UPS modules for NUCs and other motherboards, shows up as a battery in the OS. The M350 case is also pretty nice for an on-the-desk type mini-pc, clearly to hit $50 you have to minimize costs but it's really the nicest $50 case that I've used in a long time (NZXT S340 non-elite got to $60 sometimes). The first picoPSU died within a day for no reason that I can tell but the second one has been fine, with the one caveat that the laptop brick is not low-noise at all. At one point I tried putting my PCs line-outs into an AV switcher and I was getting a groundloop and I could hear a bunch of noise. It was the M350/picopsu, when I unplugged it the other two PCs (including a dell laptop) were fine. Maybe not a typical use-case but it probably isn't the best choice for your SDR host or whatever lol. But HDPlex does have those linear regs... It's super amusing that the 5700G (get the 5750G on ebay if you want ECC) is roughly as fast as my 9900K in most things but it does it at like 60W in a SFF case, can go even lower without much hit with eco mode. And it also can sorta game (in non-action stuff or older stuff). One night for fun I decided to play Team Fortress 2 at 3440x1440 on it, and it actually got a reasonably playable framerate... with a maxframes-config it would drop to around 30fps in teamfights but hey, returning to my roots playing it on my thinkpad w510/fx880m lol. I might have been able to push it farther with some res reduction but it was doing OK generally actually. It's also (again, roughly, haven't actually benchmarked) around the same speed as my 9900K in H264 encoding. The power scales very little past stock (at least during CPU workloads), just set it for silent and let it run, eco would probably be even better.

Why? Transformers scale just fine. Two power supplies is just worse in every way.
