Packing more power into the SFX form factor

A key part of technological advancement is the ability to pack increasingly complex technology into smaller spaces, allowing PCs to shink into pocket-sized form factors in the form of mobile phones and high-end gaming systems to sit in increasingly compact spaces. 

Just as the SFX form factor was starting to gain traction in the custom PC market, power requirements started to increase, thanks to a flood of high-core count processors from AMD and Intel's response with six-core, and later 8-core, desktop-grade processors. The power requirements of high-end CPUs were increased, creating the need for high wattage SFX power supplies. 

Thanks to a combination of intelligent design and some engineering know-how, Corsair appears to have packed 150W of extra power into their SF series of small form factor PSUs, with their SF750 power supply appearing on both and on the chiphell forums.  

What's even more impressive is that this new power supply maintains its 80+ Platinum efficiency levels, all while packing 25% more power into the same 125mm x 63.5mm x 100mm (W x H x L) SFX form factor. Corsair didn't need to extend their unit into the non-standard SFX-L form factor.

On the power output side Corsair appears to have added an extra 8-pin output that could support either a 6+2 PCIe connector or an extra 4+4-pin EPS/CPU power connector as well as an extra 6-pin output for SATA power cables or other peripherals.

Corsair is expected to officially announce their SF750 750W 80+ Platinum PSU at CES 2019.

Just wish they would release more smaller cases that fit a SF power supply. Currently don't like the available options and I want to get smaller than my ITXQuote

"PicoPSU's" are still in their infancy, as well as cases that support them. In theory you could save a huge amount of space in a modern ITX build by only using internal DC/DC power conversion and having the AC/DC adapter external(Like a laptop charger or as used in some game consoles). Brings up it's own issues, and some people have a hatred for those power blocks, but with a 12V input all you really need is two buck converters(Or three if input isn't 12V) to get the 5V and 3.3V lines besides the protective circuitry so in theory you could have the whole power supply essentially within the internal cabling.Quote
