I need guidance and recommendations for setting up this GPU for the first time.
I need guidance and recommendations for setting up this GPU for the first time.
I recently bought a graphics card and would like some guidance, as this is my first purchase.
I’m using the Corsair RM1000x power supply, and I initially thought I’d connect it to the "12v-2x6" port. However, upon closer inspection, it looks like I’ll be utilizing the two PCIe ports instead.
I’ve heard this cable is more dependable, so I decided to purchase it because it matches my power supply.
The product description reads: "Corsair Premium 600W PCIe 5.0 / Gen 5 12VHPWR PSU Cable - Fits Type-4 PSUs via Dual 8-pin PCIe - 12+4pin Connector - Mesh Paracord Sleeving - Black."
I’m gathering some information about the 5090 and have a few questions.
First, I need to ensure I firmly push the cable into the connector until it clicks properly.
Second, the connection to the graphics card should remain straight for at least 33mm and not show any metal protrusions.
Third, I plan to follow the instructions from Chat-GPT and let me know if anything is missing.
Currently, I’m using a 3090 with a long support bracket. Can I install the 5090 there, or should I use it separately? Also, is it safe to leave it hanging, given its weight of around 3 kg?
Thank you in advance for your assistance and advice—it’s really appreciated.
Let’s keep the discussion focused on the purchase decision rather than potential concerns about the card itself.
My logic is that investing now is better than waiting another two years for another upgrade, which might come up later. At that time, I might want to consider additional improvements like a better monitor or switching to DDR5.
Also, here are the details of my setup:
- GPU: MSI GeForce RTX 3090 Gaming X Trio 24GB
- CPU: Intel Core i9-12900K
- CPU cooler: Noctua NH-D15
- RAM: Corsair Vengeance LPX DDR4 32GB (4x8GB) at 3600MHz
- Motherboard: MSI PRO Z690-A DDR4
- Case: Corsair 5000D Airflow
- PSU: Corsair RM1000x
- Storage: Crucial P310 2TB PCIe Gen4 SSD M.2 NVMe with heatsink, up to 7100MB/s
- Monitor: GIGABYTE M27Q X 27" QHD, 2560 x 1440, 240Hz, 1ms, 250 cd/m², FreeSync 6Premium, HDR400
I initially assumed I would be connecting via the "12v-2x6" port, but upon closer inspection, it looks like I should be using the two PCIe ports instead.
I’m not sure why this is happening.
It seems there’s a need to switch to the correct ports.
I wouldn’t expect just to use the cables that came with the PSU, as that’s the standard.
There’s no assurance a third-party cable will fit properly or match the pin configuration.
A mismatch could cause serious issues.
If you need maximum performance, heavy GPUs should be supported.
Make sure to follow the manufacturer’s installation guide rather than relying on Chat-GPT.
Based on what I've observed on YouTube, the standard cables that come with the GPU 5090 aren't sufficient, and it's suggested that using a single cable connection is more effective. When I refer to "pushing as my life," it means making sure the cables connected to both the GPU and PSU are firmly clicked, seated, and securely fastened.
I own the Corsair RM1000w PSU which supplies power to my ASUS TUF 5080. I used the single 2x6 cable that came with it. There have been no issues so far.
This setup doesn't seem correct. Your PSU should include a 12v-2x6 cable in the box. It's just one wire, linking from the PSU's 12v-2x6 output straight to your card. This is the most secure and dependable method. Also, the issue with the melting connector usually happens at the GPU connector side, so even if you use the 2x PCIe to 12v-2x6 cable, the same connector will be used on the GPU end.
By the way, I purchased this specific Corsair cable about eight months ago (the 2x PCIe to 12v-2x6) to replace my 3x PCIe to 12v-2x6 adapter, but it caused problems. My graphics card would crash several times a week, requiring me to hard reboot the computer each time. Around two months ago, I noticed the issue began shortly after installing the Corsair cable, so I removed it and reinstalled the old adapter. Since then, everything has functioned perfectly.
I own a 1000x unit suitable for an RTX 4080, though it lacks the native 12V-2x6 connector. Based on your images, yours includes this connector, so you should follow that.
Additionally, the Corsair cable pin configuration draws power from the CPU (300 W) rather than the PCIe interface (150 W). This allows it to achieve 600 W using just two 8-pin cables. However, this approach is a workaround created by Corsair for users without the standard 12V-2x6 connector on their PSUs. If you have it, stick to the native connector.
Also worth noting, 1000W is quite high for a 5090 and a 12900k.
It varies, because right now I’m using a 1440p 240 Hz display, so I’m not considering 4K. If I wanted to switch to 4K, that would change things, but currently the game (CoD 6) is great, performs better than before, and I’m quite satisfied.
I connected the cable and it’s functioning properly now; tomorrow I’ll install the new one on Thursday, and I hope everything works smoothly.
My GPU temperature is about 33°C when it starts up and rises to 50–58°C during high settings, though the game isn’t very well optimized so I occasionally experience packet issues, but I’m not alone in that.
What I’m certain of is that if everything stays stable for a few more years, replacing my GPU won’t be necessary.
What cable is connected currently and which one will be installed on Thursday? I'm referring to the native 12v-2x6 that came with the PSU. Avoid using the 2x PCIe to 12v-2x6 connection. I'm puzzled about your belief that the 2x PCIe is superior—it seems like a misunderstanding. It's actually just a workaround Corsair discovered, enabling direct GPU connection without an adapter for those without the native connector. Your PSU supports the 12v-2x6 standard, yet you're opting for the hack designed for systems that don't. Surprisingly, this approach feels safer.
I'm uncertain about your reasoning, but if you're assuming the system should handle up to 1000W because the GPU isn't fully utilized at 1440p 240Hz, it's not straightforward. What you really need is a strong GPU temporary surge while the CPU is busy, which can cause the whole system to crash. The RM1000X is a reliable PSU that manages such spikes well, though it's still pushing limits.
Packet bursts in COD BO 6 are mainly caused by the CPU struggling and internet instability (sometimes due to server issues), while the graphics card plays a minor role.
Also, given your top-tier GPU, you might want to upgrade to 4k. When I upgraded from 2k to 4k, I regretted delaying the change.
Just to be sure, I never mentioned "that the 2 x pcie slots is better," because what I really meant was that you understand the saying like "if it works, it works." Maybe now that I install the new cable, something might go wrong and I'm worried, but yeah.
Also, regarding the spikes I didn’t realize about.
