PC Sherdog PC Build/Buy Thread, v6: My Power Supply Burned Down My House

[Madmick]

I was looking at CPUId last night, tonight I downloaded HWInfo and this is what I'm seeing. Do you guys like the temps?
View attachment 1113118

This second image on the bottom is the one showing the temps for the CPU. Notice you can expand "Core Temperatures" to see the core for every individual core. Yes, your temps are excellent. You can run some stress tests or just play your most demanding game for 10+ minutes, then look at the Maximum temps to get an idea of how hot it gets under load.

Also, notice the icon at the bottom left with the blue arrows pointing outwards. I suggest hitting that. It will widen this Sensors window to double wide. Then maximize the window so you can see as much as possible at once.

Well guys, the only thing left is to find an angle connector for the GPU so I can put the panel on. Any suggestions? All my google research has recommended using only cables that come with the PSU. I understand that but unless this is going to be an open case, I'll need to do something.

Be very careful here, there were reports of melting cables due to angled connectors. I thin CableMod did a recall for their angled connectors but I cannot be sure.

Also show us a pic of your build, let's see that behemoth of a GPU!

Wait, what? You being serious here?

You went with the Corsair PSU, right? The article I already linked you about the appropriate PCIe connector for the GPU had a section with a hyperlink in it about angled connectors if upon assembling you found you didn't like the bend from the default cable.

Yeah man, I'm serious. I want to find a safe solution to get the GPU cable into the case without bending it. I don't want open case, would disrupt airflow

I went with the Be Quiet 1200w one you recommended. Sorry, I thought I mentioned that earlier but looking back I don't think I did.

Ah, okay, I'm pretty sure they would all be interchangeable despite the brand given it's the same voltages running across lines, but you can go with Be Quiet's own just to be safe:

12V-2x6 / 12VHPWR 90° Cable PCI-E from be quiet!

The final touch for a perfect PC

In the meantime, it's not a disaster to keep the side open if you wish. Dust and particles don't accrue that quickly if you're not in a sawdust mill. You can just blow it out with compressed air and wipe down whatever you can once the cable arrives.

@Madmick Edit: Whoops sorry didn't see your post after.

Also I read on Reddit that there are adapters by Corsair, say, that they say are NOT compatible with the MSI Gaming Trio OC, since the connector socket is too deep. My plan is to inspect it when it arrives and then see if the prongs are the same depth. A little worried but if this works, it beats getting a new case.

Yes, do your due diligence on this, and keep your receipts. Heed what @Slobodan told you. There's been an issue with some of these 90 degree cables.

Cable maker advises against using old 12VHPWR cables with RTX 50-series GPUs

Moddiy warns users not to use its 16-pin cables made in 2024 or earlier on RTX 50-series graphics cards.

PCI-SIG Issues Warning to Members Following NVIDIA 12VHPWR Lawsuit

PCI-SIG has sent out a statement warning members that manufacture, market, or sell products with the new 16-pin 12VHPWR power connector that they should take all appropriate and prudent measures to ensure end user safety:

www.thefpsreview.com

I don't know what the manufacturing date was on that cable by Be Quiet. You should probably take some time today to look into the latest discussions you can find on Reddit and elsewhere about the 90 degrees cables with the best reputations for build quality for use with the RTX 5090. You don't have to rush this. You want to get it right.

Turn off the Pc, put the side panel on and take/post a picture of the bend here. *If the panel cant even be placed before screwing in and is bending the GPU power cable dont bother.

Open side panel only aids in airflow.

Directly contact bequiet customer support for a cabling solution: https://www.bequiet.com/en/contact/service


Include case, GPU and PSU models. Even supply technical data links to the case and GPU to make the representatives review easy. For this is a potential fire hazard. An no active user here should be giving advice on a solution. Especially ones who said this problem wouldnt happen.

I got two cables. One from Cablemod, and another one from Be Quiet.

The problem with Be Quiet is that the "Variant B" is out of stock, so when I called Be Quiet they had me order from Groovesland. The shipping cost more than the cable, but at least it's official.

This guy has done some videos on the topic.

I have a mind to try the Cablemod one; it arrives tomorrow. One of their reps told me in reddit it was completely compatible with the PSU I have. I would have tried the MSI cable that came with the GPU itself, but it's a 12VHPWR to FOUR PCIe slots, and I don't know of any reasonably priced PSU that has four extra. Mine has two.
I've also heard that the single cable truly is the way to go. As the guy you included above said, I should keep my eyes on HWiNFO and say a prayer.

As I understand it NVidia will honor warrantees related to this. Hoping for the best here so I don't have to even call that in.

This is CableMod's business, so I think that's sound logic. Everyone agrees issues were caused by NVIDIA's poor design, not necessarily by poor cable quality. Since this is their precise niche to fill, I don't think anyone has as strong an incentive to make sure their cables work properly and safely to accommodate that mismanaged design, not even the PSU manufacturers, so I'm sure they put in extra work after the melting cable drama hit to adapt. As he touches on in the first video above, it's also sound logic not to mix and match brands because you guarantee everything is designed to a precise specification for compatibility, so purchasing the Be Quiet cable for your PSU was also reasonable. You've been smart and cautious however you proceed.

I haven't watched this guy's channel before, but I was a big fan because of his matter-of-fact approach. In my experience, boring advice tends to be the most useful.

• Limit to as few connections as possible, ideally a single cable, and don't use any adapters if it isn't necessary.
• Related to the above: buy a PSU with a native 12VHPWR or 12V-2x6 connector (you already have).
• Don't constantly plug and unplug the cable into the PSU. Respect the 30x lifetime mating cycle rating.
• Make sure the connection is matched and secure for each head in this mating.
• Don't run the cable across the GPU in a way that it's touching the hottest exposure of the PCB (this is where your 90 degree solution should help).
• Construct your build as to afford airflow across the GPU.
• Consider power limiting or undervolting strategies to reduce heat. This is extra work, but if you can maintain performance and stability while lowering the power fed to components, it's actually an ideal aftermarket tuning strategy for any build a user assembles. Theoretically, it will increase component longevity.
• Use any of his recommended monitoring techniques to be sure your cables aren't running hot.

All very sensible stuff. Like he hints at, he thinks this is largely a "scarebait" topic, and in reality will very rarely be an issue, but it's good that you're approaching it with a better-safe-than-sorry mentality.

Cablemod angled cable is in. The GPU Core Voltage is between .8 and 1.040 with an average of 0.834V.

I haven't tried to load it yet. Can you guys tell me if this is normal and healthy?

Contact MSI and Nvidia. No one here is qualified to answer these questions.

Also worth noting that modular PSU cables arent like USB. They arent designed to be plugged/unplugged hundreds of times. Most PSU cables are rated for thirty(30) uses.
