A Little Start of the Weekend Update:

A plan for how much power to have available, and how to manage that is always one of the early things to have figured out on a new build.

It isn't usually a big deal, unless of course, you're planning quad OC'd GPU's, multiple pumps, half a bazillion fans for mega rads and plenty of OC on the CPU.

OC'd 7970's are pulling over 300W a piece, nearly 200W for an OC'd 3930K, 100W for 20 rad fans, 150W to 200W for 6 D5's, it can add up quick.

The biggest PSU seems to be the Lepa 1600W, which is made by Enermax and to its credit has received very good reviews. I was thinking about using it which is why I read the reviews.

The downside is that while it's a powerhouse, I'm still pretty old school and prefer single rail.

I'd also like to have more power capability, so that if I need 1600W, I can get it while not running the PSU at 100%.


To that end, I opted for a multi PSU setup.

The Main PSU will be located in the usual PSU location of the new 820, same place as it is in the switch 810 and the phantom.

The secondary PSU is going to mount under the optical drive cage in place of the HDD cage, using the mounting sliders from an 810, so that it can slide in and out.

The main PSU will run the Mobo, one GPU, WC pumps and rad fans, and case lighting.

The secondary PSU will run the other 3 GPU's.

Now it becomes clear why I got 2 of the NZXT Hale 90, 1000W PSU's.


To get the secondary PSU set up, it needs to turn on when the primary turns on, and since it's for GPU's only, it doesn't need all the cables that NZXT doesn't normally modularize.

So I hacked 'em off . . . or carefully removed them, depending on one's perspective.

Once I had the PSU open, I wasn't comfortable with running 3 GPU's off the rear modular connectors, as the wiring to them and the PCB itself, just didn't look like that was a good idea.

As an alternative, I took 2 of the 8 pin extensions that come with NZXT cases and cut the male end off, since the female end is identical to the modular connectors on the PSU, and connected the wires to the locations from which I had removed the original non-modular cabling.

The result is a fully modular PSU that should be easily capable of running 3 hi-end OC'd 7970's.

Well it will be as soon as we have a way to turn it on . . .

I brought out the green "turn on" wire and a gnd wire and made up a relay board, so that when the primary PSU turns on, its molex connection to the relay board delivers 12V and pulls in that relay, turning on the secondary PSU.

Initial testing shows everything to be working as planned.

I'll work on getting it mounted tomorrow.

Below are some pics of the PSU mods:

Big pile of wire to add to my "usable scraps" bin:

Notice the pressed on connector on the black wires group, that's supposed to be securely soldered to the PCB, but it came out by itself, a real bad QC issue that could have caused problems.

My big azz soldering gun wasn't enough to unsolder the connections. I had to cut the wires off, and then drill the solder/wires out of the connectors to have a place to put the new wires from the re-purposed 8 pin EPS extensions in.



Here's the PSU open where you can see the 8 pin extensions wired in as 12V sources:
The regular NZXT cables connect to these interchangably with the rear panel connectors.



Here's a close up look:



Here's the cover / bottom back on and everything is still working: thumb.gif
You can see the black and green wires at the bottom of the pic. They ave a jumper on them as I hadn't made up the relay board yet



Here's the little inline relay board. You can see the molex plugged into a small PSU to test the operation:



Here's a close up of thr relay board, nothing fancy at all. I'll put some heat shrink around it when I get some big enough, after I took the pic, I put a few coats of clear laquer on it to keep out moisture:

I like it! Couldn't you put that little relay inside the power supply though? Maybe in one of the outlined sections I have in this picture. Looks like there is a bit of room on both selections on the modular side of the psu, or maybe you could attach it to the backside of the little daughter-board with some acrylic or something in between to prevent any shorting... just an idea.

Did you do the sleeving? I think I would have opted for something with a little tighter weave. Just saying. Don't know how visible that's going to be in the grand scheme of the build.
Otherwise....good planning!
How do you handle the ground between the two psu's? Or is it necessary to have a common ground?

I will likely put it inside at some point before all is said and done.
Some of those spaces are not as big as they look with the cover off and the fan not in place.

The first order of business was to make sure everything works well, and having it external will make troubleshooting easier if problems arise.

I just left the stock sleeving, and since I had to push it back a bit after cutting the connector off, it opens up considerably. As this is more of a "test run for the concept" than a finished mod, I'm not overly concerned with its appearance at this point, as it will be refined later for length and sleeve color once it's in place and I have more information and other factors to work with.

As far as grounding between the 2 PSUs, the AC line side of each connect thru the 3 pin power cords where they plug into the line. Adding a ground strap to the case, since the mounting via the plastic sliders would isolate the PSU from the case would be easy enough, but keep in mind that all the GND connections are also tied to the PSU chassis gnd, so really it would just be redundant.


Keep up with the critical eye guys.

While I've probably had the same thought as you, there's going to be some that "somehow got by me."

Saturday evening update:

I mounted the sliding rails from the top of my unused 810 HDD cage to the PSU case, having already mounted the interlocking half to the underside of the optical drive cage.

I'm really happy about how this looks and how it's going to work out in the build.

You also shamed me into mounting the turn-on relay inside the PSU case, sooner, rather than later,. . . . . But that's OK, it looks *much* nicer and I left enough pigtail length for plenty of options.


I drilled and tapped the PSU cover, but sheet metal without a push-thru-dimple doesn't hold much, so I used the plastic locking feet and nutted the screws on the inside to be worry free.

The plastic insulating liner goes over the nuts to be sure they can't short to the PCB:
You can also see in this pic, why I didn't want to run all 3 GPU's from the back panel plugs . . . .
There's just not that many parallel wires connectiong the back panel with the 12V & Gnd connetions on the main PCB




I trimmed the perfboard down a bit and rewired the relay so that it fits nicel in the rear corner, mounting it with some 3M VHB double sided adhesive.




Here's a good look at the PSU with the slider rails installed:




And here's a test run with everything re-assembled:




And the first time installing it into the case:



This fits so nicely to the front, that it flips the power switch as it goes in or out:




Here it is installed before I trimmed the protruding tabs off the upper slider half:
These definately get in the way of installing an accenting acrylic side panel on the drive cage.



And here it is trimmed flush:
Once the back edge of the drive cage, where the thumb screws used to come, and the tool-less bay locks are trimmed off, I'll make an acrylic side panel shaped like a backwards "L" to hide the PSU cables.






And from the opposite side:




Here it is from the front, I'm not sure just yet how I want to mod this area, but the PSU has to exhaust out thru that grill, and for that to happen, I can't have a fan blowing in against it. . . . So the 200mm is out, the power plug is in the way of that anyway.




Time to plan and engineer a bit before I start cutting again,

Darlene

holy cow that looks like it was intended to go there exept for the 200 mm fan could you downsize to 180 if you wanted to use it

but nice work on the rail
can you take a pic on how it stays up by itself
im guessing its like this shape

Diva you sure have my attention, Subbed for sure. nice work so far!

Subadubdub!!!! I'm lovin' it like McDonalds thumb.gif. I really like the PSU placement. It looks... familiar... thinking.gif Although your rail system is much nicer than my zip ties. I really need to figure out a new mounting system. Until then, though, it's cheap/efficient/effective.
