WEBVTT 00:00:00.080 --> 00:00:07.680 In spite of its well publicized issues, the infamous 12pin GPU power connector 00:00:05.120 --> 00:00:12.320 championed by companies that shall not be named is still out there and still 00:00:10.320 --> 00:00:17.279 overheating, sometimes to the point of catastrophic failure. And while we could 00:00:14.719 --> 00:00:23.359 leave it to gamers and influencers to fix it, CIC, who sponsored this video, 00:00:20.000 --> 00:00:24.800 has a better idea. It's called Opiggard, 00:00:23.359 --> 00:00:28.640 and we're expecting it to show up on their high-end Prime Series power 00:00:26.400 --> 00:00:33.280 supplies sometime later this year. But how does a power supply, which is way 00:00:30.960 --> 00:00:37.440 over here, fix a burned out connector on a GPU, which is way over here? To answer 00:00:36.320 --> 00:00:41.920 that, we need a little bit of background. So bear with me here. Wires 00:00:39.920 --> 00:00:45.600 that are carrying an electrical current heat up due to the collisions between 00:00:44.160 --> 00:00:49.840 the electrons that are flowing through them and the aluminum or copper atoms 00:00:48.000 --> 00:00:53.920 that make up the wire. More current means more collisions and therefore more 00:00:52.160 --> 00:00:58.640 heat. But there's a simple solution to this. Ohm's law states that if we lower 00:00:56.160 --> 00:01:03.680 the resistance of our wire, usually by using a big chunky one, we can carry 00:01:01.199 --> 00:01:09.840 more current at a consistent voltage. And while a 5090 at full load will 00:01:06.720 --> 00:01:12.080 result in a noticeably warm power cable, 00:01:09.840 --> 00:01:16.479 9 amps is well below the generally accepted safe current capabilities of 00:01:14.560 --> 00:01:22.560 the 16 gauge copper wire that you would find in a 12vt 2x6 power cable. So what 00:01:19.759 --> 00:01:27.439 causes it to overheat? Well, as usual, it's that pesky real rain that always 00:01:25.280 --> 00:01:32.400 seems to show up and ruin our theoretical parades. Whether it's due to 00:01:29.840 --> 00:01:36.720 user error or manufacturing variance, sometimes the connection between your 00:01:34.320 --> 00:01:41.200 cable and your power hungry GPU just plain isn't perfect. And when this 00:01:38.720 --> 00:01:46.079 happens, that resulting poor connection acts like a much smaller gauge wire, 00:01:44.000 --> 00:01:50.479 dramatically increasing resistance in that spot, which if you remember, 00:01:48.479 --> 00:01:55.920 reduces the current that we can safely carry without overheating. And once one 00:01:53.920 --> 00:02:00.240 of the pins in a connector fails, the situation can go from bad to worse as 00:01:58.640 --> 00:02:04.759 the remaining ones try to pick up the slack, increasing their temperature, 00:02:02.399 --> 00:02:10.080 increasing their chance of failure until finally. Now, there are ways for GPUs to 00:02:07.920 --> 00:02:16.400 protect themselves. But for what we can only assume are cost and space-saving 00:02:12.239 --> 00:02:19.200 reasons, many 50 series GPUs don't. That 00:02:16.400 --> 00:02:24.239 is where CIC comes in. By implementing the current and temperature sensing that 00:02:21.680 --> 00:02:29.599 GPU manufacturers have neglected directly into their power supply, CSIC 00:02:27.520 --> 00:02:35.599 can constantly monitor to ensure that current draw is balanced across every 00:02:32.480 --> 00:02:37.680 pin in a 12vt 2x6 connector and then 00:02:35.599 --> 00:02:41.280 they can proactively power down the system in the event of a poor 00:02:39.360 --> 00:02:46.000 connection. And this has the potential to become even more important as time 00:02:43.599 --> 00:02:49.680 goes on. Mark from Overclock 3D illustrated this perfectly in an article 00:02:48.239 --> 00:02:54.239 where he showed the difference in current balance between a well-used 00:02:51.760 --> 00:02:59.680 cable from his test bench versus a brand new one. And you got to remember this is 00:02:56.400 --> 00:03:02.159 on the exact same power supply and GPU. 00:02:59.680 --> 00:03:06.959 Only the cable changed. And it kind of makes sense. I mean the 12vt 2x6 00:03:04.560 --> 00:03:12.000 connector is only rated for about 30 mating cycles. Meaning that over the 12 00:03:09.760 --> 00:03:16.159 years that your CS Sonic Prime power supply is going to be under warranty, 00:03:13.840 --> 00:03:19.840 you could easily wear that cable out, especially if you're a frequent upgrader 00:03:17.840 --> 00:03:23.920 or a tinkerer. I'd like to believe that by then the industry will have moved on 00:03:21.519 --> 00:03:28.239 from this catastrophe of a connector or at least improved the safety on the GPU 00:03:26.080 --> 00:03:33.680 side, but you know what they say, hope for success, plan for failure. Oh, this 00:03:31.200 --> 00:03:39.280 is cool. CIC is iterating on their Opsync technology with Opticync 2.0, to 00:03:36.640 --> 00:03:44.879 the original idea was to move more of the components away from manual assembly 00:03:42.080 --> 00:03:48.720 and integrate more cooling into the PCB of the power supply. And now they're 00:03:47.200 --> 00:03:53.040 taking that to another level by automating the placement of heat sinks 00:03:50.879 --> 00:03:57.360 over MOSS components on the board, helping to improve both the consistency 00:03:54.879 --> 00:04:00.560 of their manufacturing and cooling. Keeping with our theme of cool stuff, 00:03:59.040 --> 00:04:07.040 there's a couple other cool things here in the booth that are worth checking out. After finding what they described 00:04:04.159 --> 00:04:13.680 as a surprising amount of success with their 2200 watt prime power supply, CIC 00:04:10.879 --> 00:04:17.959 is upping the ante with the beefiest ATX power supply that I have ever held in my 00:04:16.079 --> 00:04:23.919 hands. A 3,200 W 80 Plus platinum efficiency unit 00:04:21.199 --> 00:04:31.040 for AI applications that has a total of I kid you not, six 12vt 2x6 power 00:04:28.000 --> 00:04:33.360 connectors. Unfortunately for me and my 00:04:31.040 --> 00:04:38.840 120 volt friends, this unit will only operate at that output on 230 volt input 00:04:36.639 --> 00:04:43.479 power. So that's a downer. But all I have to do to feel 00:04:41.120 --> 00:04:48.880 better is take two steps right over here. This is so cool. Designed by the 00:04:46.880 --> 00:04:54.000 king of wing, who bearded Linus collaborated with on the impossible 00:04:50.639 --> 00:04:56.880 build back in 2021. This is a monitoring 00:04:54.000 --> 00:05:02.160 solution for 12volt 2x6 connectors that includes much of the functionality of 00:04:59.000 --> 00:05:04.639 CIX per pin current sensing, temperature 00:05:02.160 --> 00:05:10.320 monitoring, and the ability to trigger your GPU's safety shutdown. It also does 00:05:08.000 --> 00:05:15.360 more. It has a screen that you can position wherever you want for constant 00:05:12.479 --> 00:05:20.639 monitoring. And the whole thing is built into a smart cable, meaning that it can 00:05:18.160 --> 00:05:26.639 work on any power supply. And the best part, he's apparently making the design 00:05:22.960 --> 00:05:28.639 open source. What an absolute Chad. I 00:05:26.639 --> 00:05:33.600 can see this being incredibly useful for reviewers and hobbyists alike. Less 00:05:31.120 --> 00:05:38.320 useful, per se, but definitely cool, is the new colors coming for CIC's Focus 00:05:35.840 --> 00:05:42.080 series. I've been asking for years why this isn't a thing. So, it's nice to see 00:05:40.160 --> 00:05:47.120 a major player noticing the trend towards themed builds and providing a 00:05:44.639 --> 00:05:51.759 quality option. Speaking of quality, that brings us finally to this. Building 00:05:49.759 --> 00:05:57.600 on the success of their collaboration on the Prime TX 1600 watt Noctua edition, 00:05:54.880 --> 00:06:02.000 CIC is announcing that their Prime high power density series will now use Noctua 00:06:00.160 --> 00:06:05.680 fans for their outstanding performance and acoustic profile. If you guys 00:06:04.240 --> 00:06:09.360 enjoyed this video, why not check out the one we did last year where we talked 00:06:07.360 --> 00:06:15.360 about that collaboration between Conic and Noctua and how I wanted to be the 00:06:12.639 --> 00:06:17.919 one to do it. That's okay. They did a great job.
