Parts have been ordered for a new build.

The basics will be

Threadripper 1950x on an Asus Rog Zenith Extreme motherboard and 32GB 3200mhz Samsung B die memory

4 x Asus 1080ti rog strix oc cards watercooled.

Powered by a 2000W Platinum psu.

Cooling will be provided by 2 pumps one for graphics and another for processor, 3 rads and enough fans to generate a hurricane.

All mounted into a Lian-Li case.

Construction should start in about a weeks time.

Now its time to go to work:-(

Yes, but it is being built to work rather than a show machine.

Kevin, thanks for the build list. Didn't realize you were going with four water cooled gpus. I assume from your description the cpu and gpus will be separate loops? I have learned that putting a 1080Ti into the same loop as the cpu really adds a lot of heat dissipation into the loop and increases the loop temp a lot more than I expected. If I was going to rebuild the system, it would be into a much bigger case and have enough room for separate loops and radiators for cpu and gpus.

Sounds like it should be a heck of a cruncher!
Good luck with the build.

Split combined loop, one loop for GPU's, one for CPU, into a large reservoir, EK-RES X4 250, 3 rads 360mm by 60mm 1 on CPU loop 2 on GPU's with room for another 2 in the case if needed.

A nice set-up!

I have not read the other replies to your original posting,
BUT from my experience you are going to have a problem with keeping the room cool enough. Your system will otherwise be fine.

I have a 16" tabletop 50W blower on the floor to supply fresh air in to the room. And then a duct blower aimed directly to the GPUs.

p.s. I have cut away the grills of the GPU back plates Those that face the rear end of the case with connectors for cables to the monitor(s).

A power supply could be having its own temperature regulator, by means of a built-in fan.

Do not forget that, in a same or similar way, as next that of an operating environment, for that of a room itself.

Sounds like it should be a heck of a cruncher!
Good luck with the build.

Hopefully, I have spent the last few months reviewing parts, all I need to do is put them all together correctly:-)

That has been taken into consideration, the room is well ventilated during the summer months and it will save me running the heating during the winter, thats one thing that I missed when I upgraded from my 3 x GTX470's:-)

If it gets too hot during the summer an external rad for the system would be an easy option.

Kevin

Just spoken to the suppliers, the order is awaiting conversion of the graphics cards - waterblocks have to be fitted and tested, not a job that I want rushed.

Exciting times Kevin. Yes, you don't want hiccups from the parts. Especially when you have to drain the loop to work on anything. I think you might have underestimated the heat output from the four 1080Ti's. In my two systems with that card, they output significantly more heat than the run of the mill 1070 or 1080. Nvidia-smi shows the typical power consumption under SETI task loading of around 215W compared to about 115W typical for the 1070 or 1080. So essentially the 1080Ti's will turn into a 860W space heater along with the cpu contribution. So the system will have the ability to significantly raise the temperature in the room housing the system.

My systems become the source of heat for the house in the wintertime. I use a floor standing pedestal fan at each room entrance extracting the heat from the systems out into the rest of the house and that enables me to rarely have to use the gas furnace for any supplemental heating. The problem reverses in the summer and how to cool each computer room. I had some A/C ducts reconfigured for each computer room to increase the air exchange for those rooms to supply more cooling in the summer.

Its going to be a case of trial and error, hopefully more trial and less error:-)

Heat is a concern, whether I am installing enough rad space for the cards - that is expandable I can easily get another 2 x 360 rads into the case but they will be on the air intake side of the airflow or an external rad could be an option.

Heat within the house should not be a problem during the winter, this place is fairly open plan so heat dissipates throughout easily, during the summer the place is never closed up, computer will be within a few feet of an opening window and a large external rad would be an easy option.

Pumps being fitted are EK D5 for CPU and EK-XTOP Revo Dual D5 PWM Serial for the GPU's, Drain and fill points are being fitted during initial installation so that if the loop has to be drained or partially drained that will not be too much of a problem, I have also got enough space that if I want to fit another reservoir and split the loops that will be possible.

Fans will be Noiseblockers on the rads and Be Quiet silent wings for ventilation, temp monitors on loops also being fitted.

Main system drive will be a Samsung 960 PRO SSD and the case is fitted with 6 x 3.5 hot swap bays so maybe later I will have the option to start playing with Linux just by changing the boot drives.

Other things on the to do list, my i5 is going and the i7 will be rebuilt and slightly upgraded into its case, this will probably become my main "use "machine.

Very impressive build! I was doing a quick scan of your parts list, and saw that you had a 2kw PSU, and I was going How'd you pull that off?!? and then realized you're in GB, 240v service is normal, so with half the amperage draw, you get the privilege of an extra 400w above our 'pedestrian' 1600w PSU's here in the US. So, now I'm curious, if 1.6kw is pretty much the tops for us, what is the tops for you guys over there? 3kw? 3.2? Man, talk about having a _ton_ of power available, at least potentially.

2.4kw is the limit on our standard 240V lines here.

Probably the kw limit is determined by the local country's National Electrical Code and whatever they use as standard building wire gauge size. We here in the States are standardized on 12 ga. wire for maximum 20A circuits. That is what determines the kw draw limit. I would imagine the UK uses the equivalent 12 ga wire size (3.3mm²) for their main electrical code equivalent for a 20A circuit.

Just move to 10 ga. wire and instantly get 30A ampacity and 240V gets you 7.2kw capacity. If the actual limit is 2.4kw then either they use much smaller gauge wire than the States or they have a much higher delimiting factor. That could be for safety reasons too. Though 240V at any amperage is lethal mostly. Could be just to reduce the "startle" factor when their circuits go boom.

10amps is our usual limit which gives the 2.4kw limit on 2.5mm wiring, but we do have some 15amp lines, though a plug with a larger earth pin is required for that, that supply up to 3.6kw and up to 40amps can be supplied over 6mm wiring for ovens and cooktops.

Thanks for the actual detailed info Wiggo. Was curious what the standard UK circuit was defined as. Should have remembered the actual UK 3 prong plug with the 10A fuse built directly into the plug body. I now remember having to go down to the local Radio Shack on High Street and get a pack of 10A fuses for the adapter plug I was using for the external modem power supply for my laptop on my first visit while going through factory training.

Yep, thanks for the detailed info, good education on overseas wiring. I did a quick Google, and it looks like 2.5mm is 14awg, which is good for 15a 120v. And sadly, I've seen some of that in houses built in the 60's, and just shake my head, it seems so stupid to build things _just good enough_, when the cost to make it much more robust is literally pennies per drop, to go to 12awg. Crazy. I only install 20a circuits, and only use 10awg wire for them. No issues with voltage drop, and less chance of overheating wires if something goes wrong.

As for 240 being lethal, well, I used to do appliance repair for a while and have worked with it fairly regularly, and have to admit, I've been bitten a couple times by it. 120 will wake you up, 240 will remind you who's boss. Wasn't lethal, but I guess I might be lucky as well. And probably was not securely grounded, thank god. ;-)

1600w PSU's are the normal top end, but this is available from one supplier only

https://www.overclockers.co.uk/super-flower-leadex-platinum-8-pack-edition-2000w-fully-modular-80-plus-platinum-power-supply-ca-031-sf.html

If you have a look at some of the machines that Ian "8 Pack" Parry produces then you will see why he has had one commissioned.

https://www.overclockers.co.uk/pc-systems/prestige-pc/8pack

I am also using the same case as used in the Supernova build.

Hopefully it will a build that will be worthy of his parts:-)

You may also find that the forums on www.overclockers.co.uk are worthy of a quick peruse.

Latest news on delivery - the order will be shipped on Monday for delivery Tuesday.
