those people will likely be running on redundant PSU's, and have the system in a server rack somewhere. solutions for that already exsist. this PSU does nothing for them.

Exactly my point.

Dual socket 8180M with full AVX-512 workload and 4 tesla V100s with a hard drive array.

  

Very limited, and people with those workloads are going to buy something that's most likely gray and will be running connected to a  dedicated 220v circuit.

Actually, the 8180s are designed to run under 200W, and Teslas are really downclocked Titan V (they consume ~200W), so a 1300W Supernova G2 would work fine/

You are going to need a professional electrician come to your house and setup the outlet.  No way I'd plug that in without an electrician first.

Where do you get that the 8180Ms run under 200 watts? Also the same question in regards to the V100s.

they are 200W

sorry, the v100s are 250W, but thats max

Two things; [Why make this product?]

1. It's not the highest wattage PSU ever
2. 80+gold for a 1800W PSU is garbage, most power supplies over 1200 are usually plat or titanium

I'm not a PSU enthusiast, but if I'm shopping for a 2 way SLI and a 9980XE OC'd build, this isnt on my radar for PSU's I'm considering. 

Well to answer your question on why make this product, it is the same reason why NVIDIA makes a Titan card. Why make a Titan when there's going to be an xx80 Ti variant? It's to have a "halo" product of sorts that most companies tend to produce for reasons that aren't generally geared towards the mainstream user. It's like saying why make a Dodge Challenger SRT Demon when the Dodge Challenger SRT Hellcat already exists.

 

As for the 80 Plus Gold rating, as long as you at least have an 80 Plus rating, generally you have not much to worry about. Efficiency rating isn't indicative of the "quality" of PSU per se and while ENERMAX isn't frequently used compared to some other companies, they do actually make pretty good PSUs though. 

 

So what do the different 80 Plus ratings mean:
 

Quote

The basic 80 Plus rating means that the PSU is rated for at least 80% efficiency at 20% load, 50% load, and 100% load.

The 80 Plus Bronze rating means that the PSU is rated for at least 82% efficiency at 20% load, 85% at 50% load, and 82% at 100% load.

The 80 Plus Silver rating means that the PSU is rated for at least 85% efficiency at 20% load, 88% at 50% load, and 85% at 100% load.

The 80 Plus Gold rating meas that the PSU is rated for at least 87% efficiency at 20% load, 90% at 50% load, and 87% at 100% load.

The 80 Plus Platinum rating means that the PSU is rated for at least 90% efficiency at 20% load, 92% at 50% load, and 89% at 100% load.

No offence to Jay, but I don't think he knows how to test or review PSUs. It's just not the sort of content he focuses on. Someone let me know when Aris does a review, not that I would be buying it anyway...

I'm guessing CWT is the OEM for this one?

Of course, I would rather see a review from JonnyGURU, as they would be better for review purposes. But if you have been following Steve and Jay, they have been engaging in extreme overclocking back and forth, where they have to use two separate power supplies. And I'm wondering if this might remedy that, or even provide better results.

 

As far as I know, ENERMAX makes their PSUs in house and doesn't use an OEM. At least that's how it has been for their past MaxRevo, Platimax, and Revolution87+ PSU models.

TDP isn't power draw. The 8180/Ms can hit peaks of over 700watts under full ABX-512 workloads. That's for a single CPU. I also know this from experience having a dual 8180M system.

 

Also, the same aspect with the Teslas. The V100 also has two different flavors, PCIe card which you linked to, and the Mezzanine card which is actually rated at a TDP of 300 watts. However TDP isn't an indication of power draw, nor is it a perfect measurement. They will draw more than that if there is thermal and power headroom while under heavy workloads.

I think they stopped making their own units a few years ago to save cost. Afaik most or all modern Enermax units have been produced by CWT.

I'm aware that 80+ rating =/= Quality, but that doesnt excuse the fact that if I'm pulling 1500+ watts from my system, I'd rather my PSU be more efficient (closer to 92-94%) rather than 87% or whatever the numbers are so I'm not pulling as much from the wall, especially at such high wattage's where a few %'s actually start to matter.

 

I'm not doubting the quality of the internal components, just the high wattage while not being as efficient as other PSU's on the market, and/ore not being the highest wattage PSU on the market.

Well I was surprised at first, since the US stopped using fuse panels in the late 50's (for new installations).

How so, if you don't mind me asking? Also, you can ground outlets in many different methods, some being considered safer than others. A bit off topic so I'll leave it there.

My old mobile home needed a upgrade to use 500 watts from my pc at full load and a microwave at the same time, this would probably blow everything. 

 

Edit: the source cable is probably like a oven cable, one of those real big and thick ones.

My apartment at college would have the breaker trip everytime I was using my desktop the same time as someone used the microwave. Ended up having to put my desktop on a different outlet that wasn't part of the same circuit as the microwave.

Yeah, this seems to be correct, it also looks like there are some other OEMs being used like; FSP, Fortech Electronics, Yue-Lin Electrical Tech, and Sirtec.

That's due to the spike that microwaves have when the magnetron kicks on. The draw spike is typically high enough to kick a 15amp breaker if anything else is running on that circuit. That's why they recommend installing them on a dedicated circuit.

I do understand your perspective here. But again, it is somewhat based on your use case and circumstances. Since, for instance, I imagine when K|NGP|N or der8auer are going HAM with LN2 overclocking, the last thing they are worried about is electricity cost and savings if they were using a Platinum or Titanium PSU instead. That's where I mostly see a product like this being used over some other solutions that offer better efficiency ratings and at slightly less voltage. 

 

Otherwise, I do see your point.

That would actually be a huge regression.

Yeah I am unsure. The interesting thing is that this particular microwave was notorious for this. I gave the microwave to my sister and she had the same problem at her apartment when they had a TV and some other electronics on the same breaker. Same thing happened with my dad after my sister left it with him. I haven't had this issue with my current microwave or any other microwave for that matter.

Some depending on how they were made will have capacitors in them to help the load spike on the circuit.

Wtf In italy we use circuit breakers, never seen a fuse in my life here except in 12V circuits
10A for lights, 16A for sockets

1800 watt output at 230V and 1600 watt at 115V

Yeaaaaah. Thats gonna need a 20 amp circuit. If memory serves me well, the national electric code in the US says the maximum Watts for a continuously running device on a 15 amp circuit is ~1500W.
I honestly wonder what could require that many watts. All I can think of is really a server with multi CPUs or.... Well... Linus with the forever growing " __ Gamers '1 CPU' PC"

[paddy-stone]

IIRC in the UK, we have circuit breakers, usually these are a "per room£ breaker, but for bigger items (electric ovens, boilers and such) they have their own breaker, usually these are rated for higher amperage too... we also have separate circuits for lower amperage things, like bathroom extractor fans.  Fuses are found in most appliances "plugs" that go into the outlet/socket, and the fuse is rated for the intended purpose, so that it would trip to help prevent damage/fires...our supply is 240Vac.
