To the extreme: Super Flower's 2,800W PSU with four 12V-2x6 connectors retails for $899

[Shawn Knight]

In a nutshell: Super Flower has introduced a monster power supply that should be able to handle anything you can throw at it without breaking a sweat. The Leadex Platinum unit from Taiwanese manufacturer Super Flower is a fully modular power supply with a maximum rated power output of 2,800 watts that's both ATX 3.1 and PCIe 5/.1 compliant. There are a total of 19 modular connections including four 12V-2x6 connectors.

Super Flower introduced the 2,800 watt unit at Computex 2024, highlighting its use of Japanese capacitors. The PSU also carries an 80+ Platinum energy efficiency rating, meaning it's 94 percent efficient at 50 percent of its rated load (230 V EU).

The voluntary 80 Plus efficiency rating system came about in 2004, and uses tiers to differentiate performance. Platinum is the second-best tier only behind titanium. For years, gold was… well, the gold standard, and it was not uncommon to see silver or even bronze-rated PSUs associated with entry-level power supplies.

Super Flower's latest ships with a host of built in safety features including over voltage and over load protection, short circuit protection, over power protection, over current protection, under voltage protection, and over temperature protection. Elsewhere, you will find a single 140mm dual ball bearing cooling fan with eco-minded fanless and silent models.

The PSU isn't listed on Super Flower's website as of this writing, but Newegg has it up for pre-order at a promotional price of $899.99 with an April 17 release date and a generous 10 year warranty. Interestingly enough, Newegg's listing mentions the PSU requires a specially designed medical-grade power cord, and thus should only be purchased from the official Super Flower seller store.

A power supply that costs nearly as much as a value gaming rig certainly is not for everyone, but those running heavy AI workloads or intensive rendering jobs could get some mileage out of it. As with most novelty hardware, we are just glad the option exists for those that can truly use it.

2800 watts!? Ah, cool. Prepare in advance for current and future Nvidia GPUs.

Japanese capacitors are my favorite but at 2.8kw that thing had better be using Stark capacitors.

Spec in the article states: EU 230V and 50Hz (around 15A).

However, in the US, that is basically the outlet we use for a clothes dryer (240V 30A). The 120V home AC voltage is a limiting factor in the US (standard 15A circuit can only support around 1440-1800W).

The more you know (cue 90's music and shooting star animation)

If someone manages to max this thing out, they are going to need an electrical circuit capable of delivering at least 25 amps - and a breaker to match!

I was thinking the same thing. I don't think a standard 120VAC circuit in the US can operate this thing at its rated power. I wouldn't be surprised if there is a switch somewhere on it to select between 230VAC 50Hz and 115VAC 60Hz, with the 115 also 'gimping' it to ~1400-1600W via switching some circuits.

Only thing I can think of is the "medical grade" actually means "NEMA 6-20", and its not meant to be targeted at home/gamer use, but "home datacenter" use (e.g. someone hired an electrician to run a few 240V circuits to their home networking 42U rack, and now they want to run an AI training box in their data center and need to power ~4 GPUs to do it)

I guess this would be for someone using multiple gpu’s for ai / 3d rendering - not something ordinary users would need.

Not many places have dedicated 20A plugs outside of the kitchen or workshop.

Not many places have dedicated 20A plugs outside of the kitchen or workshop.

And even a 20A plug at 120V won't deliver a full 2800W.

Won't be long before you will need a 3-phase power supply in you house......
