While it looks like the product has made an appearance on their blog as early as July, FSP Technology Inc. has just officially announced their FSP2000-A0AGPBI ATX power supply. If you’re attempting to parse the model number, then yes, the 2000 stands for 2000 watts. While it’s not a single-rail design, which would have been impressive, it can deliver six different streams of 12V@30A through sixteen 6- or 8-pin (PCI-E 6+2 pin) connectors.
At this point, you might be thinking: how can you deliver 2000W through a wall outlet? 15 amps through a 115-volt outlet has a theoretical maximum of about 1725W. Simple! Use a 230V outlet.
A better question is “Why would you drive eight dual-eight-pin GPUs?” The official answer is workstations, servers, and industrial power systems. The unofficial answer, especially considering their aforementioned blog post in July, is coin mining. Because of course it is. Of course it is.
As an added bonus, the FSP 2000W power supply is rated 80PLUS Platinum. It doesn’t look like FSP has announced pricing or availability yet, though.
So, it works as a space

Nah. The components it

Now I want to see some
Now I want to see some Blender CPU rendering Benchmarking run of this Super-Pi system(1).
“The device is based on five rack-mount BitScope Cluster Modules. Each one has 150 Raspberry Pi 3 nodes networked together (that’s 750 total Pis). Each Raspberry Pi 3 has a Broadcom BCM2837 system-on-a-chip (SoC) with four 64-bit CPU cores clocked at 1.2GHz. They’re ARM Cortex-A53 reference cores, which are the same thing you’ll find in many budget smartphones running Qualcomm and MediaTek SoCs. This adds up to 3,000 available CPU cores for the full system, but it uses only a fraction of the power needed for a computer like Trinity. LANL estimates the system will need just 1,000 watts at idle and 2,000 watts during typical usage. The maximum load is 4,000 watts. Other supercomputers use between 10 and 25 megawatts of power.” (1)

While I personally couldn’t
While I personally couldn’t see myself needing a PSU of that wattage, I certainly have enough equipment to trip a breaker if it was pulling max current at the same time. In fact, I just finished putting in a dedicated circuit for just the computer room (2 computers, 2 printers, a server, and all the networking equipment for the house). I decided to put in a 240V circuit because 90% of the computer stuff that I wanted off the old circuit (which also has a freezer, a mini-fridge and a washing machine) could do 240V with no real effort, just some new power cords that fit the new outlets. (bending conduit and pulling wire however…) It works great BTW; the lights no longer flicker when the laser printer runs. Definitely worth the effort.
You Americans and your puny
You Americans and your puny AC voltages.
Most houses have 220 here –
Most houses have 220 here – it's just split in half to most circuits.
Actually, most residences in
Actually, most residences in the US have two 120 volt circuits–each a different phase. So a single circuit (phase) only has 120 volts available. For high power use appliances such as electric water heaters, dryers or stoves and ovens, two circuits using one cable with 4 wires (1st hot, 2nd hot, 3rd neutral, 4th ground) will be run from the breaker box to the appliance. Each circuit is used independently by the appliance (only one hot to neutral). We call this 240 volts, but it really isn’t.
As a simplified example, an electric dryer will use one circuit for the heating element, and the other to power the motor.
In most of Europe, each individual circuit (phase) is a true 240 volts. It lets them use smaller gauge wiring because the current draw is lower as a result of the voltage is higher.
In the UK almost every home
In the UK almost every home has a 3KW kettle for making tea. It spikes electricity demand, it is someone’s job to watch TV and bring power stations online during advert breaks. https://youtu.be/slDAvewWfrA?t=39
240v is more efficient
240v is more efficient
240v *can* be more efficient,
240v *can* be more efficient, but isn’t always. Sure, for the same power, the current is half which can lead to lower ohmic losses, but then again, transistors have to handle twice the voltage which generally means using parts with higher losses–both static and dynamic switching losses.
Like any other engineering, it’s a tradeoff. There is rarely one clear winner. People who see a clear winner are generally not seeing the whole problem.
Regarding switching power
Regarding switching power supplies, there generally *is* a clear winner as 220V input yields greater efficiency in the vast majority of PSUs.
The two considerations aren’t
The two considerations aren’t equitable in practice. Power supplies almost universally achieve higher efficiency at higher supply voltages. In the case of typical PC power supplies, you net an uplift of a few percent. The same thing can been seen in other areas such as with power inverters. When there is a single model of inverter but with 12, 24, and 48 volt configurations you will see a jump of a couple percent efficiency under load each time you go to the next higher input voltage model.
Unrelated side note about common residential US mains voltages: 110, 115, and 220 aren’t real mains voltage specifications. 120 and 240 are. Commercial properties often have three phase power at higher voltages and as a result have things like 208, 277, 480, and others that aren’t seen in residential housing.
115? What backwards country
115? What backwards country are you from? In USA, the max is 1800W (15A x 120V). I ran multiple 20A circuits in my house, four dedicated to my server rack which doubles as my AV rack for a grand total of 9,600W on tap.
115V is US too. 110V to 120V
115V is US too. 110V to 120V is standard, they both mean the same thing. 110V or 115V just account for a voltage drop throughout the building’s circuitry, especially at high current loads. So 1800 watts total power may be consumed, but not all of it by a device plugged into an outlet. Why do you think the largest power supply currently available on normal 120V power is 1600 watts? It’s because drawing any more than that is unsafe, and maybe not even possible, without a dedicated high current circuit.
Even that can be quite
Even that can be quite dangerous. One of my friends houses still had knob and tube wiring. They were running about 6 computers in one room playing WoW at one point. I am surprised that they didn’t burn the place down. That old wiring was mostly meant to run lights, and that is about it. If you are running newer, high powered computers in an old house, you probably should check the wiring.
If you ran additional
If you ran additional circuits meant for a server room, you should have run 220. You could have run half the copper.
If you are going to put all
If you are going to put all of that in one place, then it seems like just running a sub-panel would be the way to go.
Now with all the debate going
Now with all the debate going on maybe an article dedicated to the 2000+ Watt home system users who may be building some large home gaming/media/rendering servers for the house. So a How to for wiring up a room for the server/HTPC sorts of systems.
That MZ31-AR0 (rev. 1.0) Epyc/SP3 motherboard has 5 PCIe x16 slots with 4 being PCIe x16/16 and one being PCIe x16/8 and the MB also has 2 PCIe x8/8 slots. So this MB/options is going to need at least 2000+ Watts and it would be probably best to look at a redundent power supply to keep any long rendering runs from being interrupted, and some UPS capabilities also.
I’m Looking at some of the specials on some Radeon Vega FEs and 4 of those undervolted for rendering workloads using a 16 or 24 core Epyc CPU SKU is going to need 2000+ Watts for the CPU, GPUs and other devices plugged in.
For those living in small apartments some tips on figuring out which of the apartment’s outlets are sharing the same breaker for folks that do not have access to the breaker box(breaker box is not in the apartment)/no access possible.
Isn’t it supposed to be
Isn’t it supposed to be limited to something like 80% of the maximum for safety reasons?
Damn wat e
