e17: December 18th, it looks like Lian Li is making a 90 degree adapter for 12VHPWR with a thermal pad and microcontroller that monitors temperature and can cut power if it detects that things are getting a little too toasty. No further information regarding pricing nor release date available at this time. For more on this subject, see our A Basic Guide To Motherboard, Case, and Power Supply Form Factors feature. The arrival of two high-wattage SFX PSUs comes as an exciting prospect for small form factor PC builders, anyways. With this much power under the hood, you needn't have to worry about hitting the power threshold of your PSU, just whether your components will actually fit in your choice of Mini-ITX case. e3: Added Lian Li's SFX PSU. As noted above, this is not compatible with 40-series GPUs. Added rumor / leak about Corsair possibly releasing an SFX-L series.
The use of a cutting-edge PFC circuit in combination with a fully digital platform seems to be the key for record-setting performance. Besides its super efficiency, the AX1600i also offers great load regulation, amazing transient response, a long hold-up time, and unparalleled ripple suppression. Moreover, the great benchmark results are accompanied by quiet operation, enabled by a relaxed fan profile and a high-quality FDB fan. Using the Corsair Link software, you're able to choose between three fan modes: performance, balanced, and quiet. e18: January 2nd, happy new year! Galax has introduced the first ever (to my knowledge) PSU to have 2 native 12VHPWR connectors on it. Added to the list, although at the moment it's only available on Chinese retailers. I assume this will be coming to the West soon enough, but no firm details at the moment. We haven't managed to confirm the exact PSU platform powering the Cooler Master V SFX PSUs, however, though we can confirm it's not Cooler Master's own platform. The company recently introduced its own PSU design with the XG Platinum PSU, meaning it's created entirely in-house, rather than relying on another OEM's design and construction. The unit features a 135mm MagLev fan with custom rotors for superior cooling at low noise levels. It has zero revolutions per minute mode for loads up to 40%. Pros: The Corsair RM1000x belongs to the same family as the RM1000x Shift. It’s also incredibly well-built, with an 80+ Gold certification and over 90% peak efficiency.
The Quietest SFX-L PSU
The unit is fully modular and has an 80+ Gold certification with up to 90% efficiency. Yet, despite the small form factor design, it still has a 120mm FDB smart zero fan with a zero RPM mode at up to 30% load capacity. Pros:
The Seasonic SSR-1000TR is their best offering in the 1000W power range! It’s fully modular and 80+ Titanium-certified. It has a peak efficiency of 94% at 50% system load capacity, making it ultra-powerful for high-performance PC builds.The Corsair RMx Shift Series PSUs are exceptionally built for a highly reliable power supply to extreme PC builds. They feature innovative side-mounted connectors for an easy DIY building experience! In fact, it's going to be quite the job to stuff anything close to 1300W inside a Mini-ITX case. There's only one PCIe port on a Mini-ITX motherboard, and it's not like there's many headers for much else. That said, I'm sure someone will manage it: a truly overpowered PC, not much bigger than a loaf of bread. Compiling a list of the best 1000W PSUs without featuring a Seasonic power supply is virtually impossible. The brand is known for its top-tier power supplies, built with top-of-the-range internal components for unmatched reliability! e23: March 12th, Thermaltake has launched their SFX form factor PSUs (conveniently named the SFX ### series). Keep in mind that the 1000W version is SFX-L. Thanks u/natdisaster for the heads up.
e2: Added ASUS TUF line, updates from the official ASUS Discord re: availability of the ASUS products.Minor update November 18th: GamersNexus has put out another video (and probably their last on the issue barring any major updates). tl;dw: SSR-1000TR has a 135mm FDB fan with a premium hybrid fan control. It runs in a fanless mode for loads up to 40% and is virtually silent for loads up to 50%! The fan has an industry-leading life expectancy of up to 50,000 hours at 40°C. Pros:
e9: FSP group PSUs available as of late November 3rd US PST. Looks like PTM Pro are still up for sale as of the time of this writing. Make sure you are purchasing one that is clearly labeled ATX 3.0 / PCIE Gen5, ( such as this), as they are using the same model name as the non-ATX 3.0 version otherwise. Any adapter or native cable can fail, but these failures are overwhelmingly uncommon and many are avoidable. Consider upcoming GPU power requirements. Although the best graphics cards are usually more power-efficient than previous generations, their power consumption increases overall. This is why the latest 12+4 pin connector that the upcoming generation graphics cards will use will provide up to 600 W of power. Currently, a pair of PCIe 6+2 pin connectors on dedicated cables are officially rated for up to 300W, and three of these connectors can deliver up to 450W safely. You should also add the up to 75W that the PCIe slot can provide in these numbers.I am in the US so will be going off of that for general availability, all prices listed in USD. Will list regional differences as needed. That being said, here’s where we are (G = Gold, P = Platinum, T = Titanium): Its unique features include ROG heatsinks, a 120mm ARGB-illuminated fan with an axial-tech design, and dual ball bearings. They provide 0dB cooling for loads up to 40% and a longer lifespan for reliability. Pros: It features a top-end, enthusiast-grade build quality with an 80+ Platinum rating and up to 92% efficiency. It’s ATX 3.0 compatible to deliver up to 600W power to next-gen PCIe 5.0 GPUs.
Great Deal
