two completely silent ,very quiet temp controlled fans:



compare with sfx and dell brick:






merely larger than a 2.5inch HDD:


length is 11cm:


width is 8.4cm:


thickness is 4.2cm


native cabling:
the GFX ATX12VO psu has dual independant modules with 12Vsb and 12Vo,controlled simultaneouly by ps-on signal:
each half of GFX can be 200w/300w ability,so the combination power is 400w(200w+200w)/500w(200w+300w)/600w(300w+300w)
each module is mostly passive cooled by half of the case ,meets 80plus platinum standard.upto 94% under 220Vac and dropped to 91% under 110Vac low line.


special main control unit for MB 24pin ,this dirctplug accept 12Vsb from GFX then convert to 5vsb for MB standby power,to control pson signal then convert 12VO to 12V/5V/3V3/-12V for MB internal circuits and CPU,two EH modular connector for sata SSDs:





GFX can be configuated as 12Vo1 for CPU/MB,and 12Vo2 for GPU,powered by each Module inside GFX independantly.also GFX has a manual power switch to turn on working as a simple 12V brick,for 12V archdaemon plug.and when using as external brick ,the two modules 12Vo1/12Vo2 can be combined into one single large current 12VO.

small mr30 as ac-in then convert to usual C14,C6 etc.:


with custom cables it has very simple layout:

Great job, very interesting.

A few questions:

1) Is the GFX / GTX (Gury Form Factor) compatible with some existing form factor like FLEX or do have case designers to adapt the new GFX standard for their cases?

2) did you design the AC-DC PSU from scratch by yourself or are you using some customized / modified OEM PSUs?

3) how about safety features like e.g. OC, OV, UV, OT, SC protection?

4) any idea about the price, let's say for the 500W GFX?

Thanks in advance. :)

Looks like a hair wider than FlexATX but so much shorter and so many fewer cables. 12V forever!

Don't find it that small to be very honest.
Plenty of off the shelf (professional) PSU's available, like from Meanwell for example

Meanwell EPP-500-12? No housing, no fan, same volume. Now show me a 600W version.

I think this is a significant move forward for 12v power supplies assuming we can get some more details.

Well a case wouldn't be to difficult to make with a bunch of fans in it.
Quite some Meanwell supplies can be used in parallel, or (even better) you use a separate PSU for the GPU.
RPS-400-12 is also a nice choice, there are a lot other alternatives.
For a fraction of the price, with full warranty support and UL certification.

That was a typo, I meant RPS-500-12 actually.
Both are from the same family.
There are also other manufactures like Bel, XP Power, Cosel etc.
