Sorry for the rotated images... I took all images with my phone, and moved to my work pc. I rotated them before upload, but for some reason they reverted... So yeah /:

I built this machine for gaming needs, and future possibility of video editing.

I ran into a few bumps in the road while building this computer, but in the end I think it turned out well. I still have to buy custom cables, and take more pictures.

One major flaw that I encountered was that the power supply can't handle my processor when it overclocks because it can't output 25 amps on my cpu rail. I was planning to overclock the processor, but when it auto overclocked while I was playing some games my computer locked up. I will eventually have to get a new PSU if I want to overclock.

If you look at one of my pictures you'll see there is a scuff mark on the case. The case was a little damaged in shipping. Which was kind of a let down, but I'm just going to deal with it.

Part Reviews

CPU Cooler

This is an amazing cooler. It does everything I need it to. It keeps the I7-5930k unbelievably cool. The stock fans are a tad noisy are my only complaint.


The bios on this board is very intuitive, and easy to use. I enjoyed building with board immensely.


Great case. The build ends up looking neat and tidy, there are lots of velcro cable tie downs, and great airflow. The only downside, which you should expect from a full tower, is that it's a little large, and quite heavy even without anything in it. With all my components in it I nearly need a dolly.

Power Supply

Great power supply. It handles most everything. The only thing is that it can't handle overclocking of the new I7 processors... I wasn't aware of this. I have had to turn off every little option in the bios to make sure my processor doesn't auto overclock... if it does then computer locks up and i have to restart it. I'm not entirely sure what it is. I think the processor when it overclocks pulls 25 amps where this can only output 24... but I'm just spit balling at this point. Overall great power supply.

Case Fan

Great fans, quiet, with ample airflow.

Sexy build!

But, I have a hard time believing it's your PSU. I have the 1000P2 with an OC'd FX 8350 and 2 OC'd GTX 760s and it's never had any form of issue, the 1300W version should be able to handle what you have easily. I think it may be a motherboard problem or a BIOS setting that shouldn't be flicked on/off.

I realize this old but other people may see that want to buy the PSU. The PSU isn't the issue, its something. The PSU offers plenty of wattage, and has great ripple suppression and voltage regulation.

I think the processor when it overclocks pulls 25 amps where this can only output 24...

It can do over 100 amps on the 12V rail. That isn't the issue either. The issue is likely you just got a really really bad CPU that doesn't want to overclock a bit.

This is correct, this unit is a single rail unit based on the Super Flower Ledex platform, its rail delivers 108AMPs on the +12V rail, the OCP would not trip at 24 or 25AMPs, the 5V and 3.3V Rails can supply 24AMPs combined so unless there's a serious fault it's not the PSU there's a problem with your system if your pulling high AMPs from these. There is nothing on CPU over clocking shutting down this PSU I can even find. So it's another component that has issues or an unfortunate loss in the silicon lottery. There was a recall on these PSUs back in 2011 but that was an overheat issue however any manufactured after the bad batch date don't have that issue which was due to some missing thermal pads. Check out johnnygurus review of this PSU and the ledex platform it's an extremely well build PSU that would produce easily enough AMPs for multiple GPUs and decent overclocks. yes I know it's an older thread but I agree with the poster above miss information can sway people away from a good product.

Correction the platform is Leadex not Ledex my iPad kept changing it

Can't wait to see finished pics :)

I really doubt that the PSU can't handle your overclock. I would think it is something else like the motherboard or bios settings, but you could be right... Great build!

bennyboombotz 1 point 49 months ago

with that psi you could add another 980 and be fine. I could run an over clocked 4790k and ski 980's on a RM 850

Devouringbowl57 1 point 49 months ago

Nice build, but man it's hard to see the Enthoo Primo without like 6 rads in it and 20 fans, nice cable work though.

RIacobo 1 Build 1 point 48 months ago

Hey man, really doubt it's your PSU... Even overclocking your cpu, and running SLI, at 100% load, you might be hitting 650 - 700 watts max. It is probably something else... Hit the forums and see where you are at setting wise in Bios.

Great vid on PSU's: https://www.youtube.com/watch?v=ajiN9aVOv4A

Awesome resource on 'simple' OC for your CPU: https://www.youtube.com/watch?v=Nj4ixZE7EWo

I'm running a single 980 EVGA FTW (OC'd almost to max), an I7 5930k (4.5 OC), and oc'd ram(3000 ddr). And at 100% load CPU / GPU (including fans and drives) I hit 475W max... I'm running a Corsair 850i PSU.

My settings: bclk / strap 125, cores set to 36, voltage at 1.28 gives me a 4.5ghz OC and 3000 DDR.

If your PSU was faulty it would most likely not boot.. they are sort of an off / on thing. If a PSU rail is bad, any stress would set it off, which could be the case. But I would check settings and maybe run a volt meter on there and see whats what. If anything check your 4 voltages In Bios and see if anything is off. It's most likely a setting in bios... Make sure you are running the latest BIOS, set everything to default and only change the few settings listed. See what happens.. and let us know!

Awesome build :) How is that 980ti tandem working for you now? Do you have some tasty benchmarks?

zetanker submitter 4 Builds 1 point 42 months ago

Thanks! Amazing. I love it. It eats up anything I throw at it.

jpereira95 1 Build 1 point 46 months ago

Sweet! One question: I have a similar build in mind with the same GPU's and CPU, is a 1000W enough power or you need to go all the way to the 1300W as you did? The build I have in mind will need 736W and I'm planning on overclocking both the GPU's and the CPU. Thanks man

zetanker submitter 4 Builds 1 point 42 months ago

I would say that 1000W would probably be enough.

DJRex14 1 point 46 months ago

Where are the 980 ti's in the picture?

zetanker submitter 4 Builds 1 point 42 months ago

I originally bought 980s and then when they were released I upgraded with the EVGA upgrade plan and haven't taken updated pictures.

Bigguns222 1 point 46 months ago

I'd love to see some benchmarks. This is very close to a build i'm planning for the end of the summer, and I'd like to know if it's performing the way you'd hope it would, especially at 4K.

noap7 1 point 45 months ago

So this cards still goin strong?

zetanker submitter 4 Builds 1 point 42 months ago

Yeah both cards are still alive and well. I still max everything.

KB_Evolved 5 Builds 1 point 39 months ago

Did you ever figure out what was happening with your build? I see you think its your PSU which seems very unlikely with such a high end/wattage unit.

If it was the PSU did you go with a different unit? The x99 really comes alive when OC'd. With the 5820k I was able to get it above 4.5GHz and was seeing nearly a 30% increase in performance in most benchmarks over stock.

IMO the x99 dominates and is way under appreciated and under used, sadly. I sold my PC because I got a great offer and ended up going with the 6600k since I didn't need all the power of the x99 and really wanted to try out a Skylake CPU. I'm very happy with Skylake and it's more fun to OC but the x99 is absolutely better if you need the extra cores. The 5820k and 4.5 gets nearly the same single core performance as the 6600k at 4.9GHz from my experience which is saying a lot since you have 2 more cores and hyperthreading.

Anyway, I'm done blabbing. Very nice build, I love me some Phanteks cases. All the components are high end. Reminds me of a build I would do for myself.

zetanker submitter 4 Builds 1 point 38 months ago

I did quite a bit of research on my issues. It is indeed the power supply. When the CPU does the dynamic overclock, or any overclock for that matter, it pulls an extra amp. The extra amp that it pulls cannot be supplied by the power supply that I bought. I don't remember the exact numbers. I think it's 12 Amps usually and then when it overclocks it pulls 13 Amps, but the max output for the power supply is 12 Amps so it shuts off the computer. I turned the dynamic overclocking off in the bios and it fixed the issue entirely. I still haven't gotten around to buying a new power supply. I will actually probably doing that this week.

I enjoyed reading your comment. Thank you for the compliments and the information. I'm really going to have to get going on it again.

lwcdnet 1 point 38 months ago

Hey! Love the case and the build. One question: How did you recognize that the power supply couldn't handle your processor when you overclocked it? You said it can't output 25 amps on your cpu rail.
1. How did you know it required 25amps on your CPU Rail when you were overclocking? 2. How did you know your huge 1300watt power supply couldn't provide the 25 amps? (Never mind, that is just reading specs on your Power Supply).

BTW, my build also has (2) 980 Ti's (Zotac Arctic Storms, with Rigid Tubing and (2) HUGE AlphaCool Radiators (Monsta 85mmx360mm and a 480mmx60mm). It weighs about 87lbs! I built a custom aluminum angle-iron wheelie base for it. I'll post my build soon, after I take some pics of the final build).

Please let me know how you calculated the PS output requirements for your CPU overclocking needs, and what overclock you were attempting (along with voltage settings would be awesome, at least as a reference...).

Thanks and nice job!

i feel that going with the primo is for more of watercooling than air cooling. yes it comes with 5 fans but they are air flow fans so you can add a 480 in the top and have 2 on the bottom for intakes (and 2 in front and 1 in rear) Seeing this case on air feels weird. I plan to do a black and yellow build in the primo and after i save up another $900 after my build in it i will watercool it with PETG tubing. thats what the case will shine at.

zetanker submitter 4 Builds 2 points 42 months ago

You can do it how you want, and I did it how I wanted it. I wasn't comfortable spending the extra money, and I often carry my pc around to different venues. I've never done liquid cooling and was nervous about all the different factors, and didn't wanna risk the components on my first time of trying to do watercooling. Overall I spent my money how I saw fit, and it has been working great. I couldn't ask for a better computer at the moment to be honest. I love it, and what it can do. I really didn't need to spend all the money on watercooling just to make it look cooler because everything runs exactly how it should and at very cool temperatures because of the amazing air cooling potential that the primo has. I do have a closed loop cpu cooler on my cpu and that's all I really need.

I hope your build goes well, and you enjoy your pc as much as I do mine. Thank you for your comment..
