There are concerns regarding my PSU connections.
My cables match exactly what you described: two cables, each with 2 pcie (2x6). However, some sources say these aren't very reliable because they create a daisy chain, forcing you to use the longer sections instead of the middle ones. They also warn that using this adapter might harm the GPU over time. It seems safer to connect it directly to the power supply and then to the GPU, but since your power supply can't do that, that option isn't available. Additionally, having only two VGA inputs on the PSU could potentially overload it, as it needs three inputs while you'd be using three PCIe connections with two inputs each.
You have four PCIE 6+2pin plugs ready from the PSU.
Your graphics card needs three of them.
Everything seems fine.
If you need all three plugs from different cables, you'll need to buy a new PSU.
There are issues with the 12VHPWR connector on RTX 4090 cards.
If the connector isn't inserted correctly, it can melt and harm the card.
Be sure to place all connectors securely.
It's fine to use just two VGA inputs on the PSU. I assumed it would harm the unit, but it seems it can handle that setup. These two VGA outputs can support up to a certain amount of Watts. Regarding the cable, the weakest segment is often referred to as a daisy chain. All segments in the cable don't deliver power equally—longer sections are generally better for safety and performance.
your psu includes two vga outputs. you attach one of the supplied pcie cables to each output. every pcie cable contains two 6+2 connections, allowing four possible 6+2 setups. the psu is built to supply power according to these needs, so each cable with its two 6+2 links can deliver 300w total—because each 6+2 link provides 150w. this assumes both links are used on the same cable. the design ensures it won’t harm itself when operating this way. if you combine both 6+2 connections from one cable and one from another, you can safely power your 4080s gpu. the three 6+2 connections together offer 450w, but the 4080 actually draws less than 300w, so it won’t strain any link. the psu is built to handle this and will work without issues.
Thank you all for your questions.
Can I purchase Corsair products for my power supply and swap them with the 6x2 PCIe version? I’m unsure if Superflower carries them in my area.
Also, is Corsair currently offering 1000W power supplies supporting PCI-E 5.0 and ATX 3.0?
If you had to suggest a power supply that could handle an RTX 5080, what would it be?
You must purchase cables tailored for your PSU. The pin arrangement varies among brands and models, requiring customization for each specific unit. Additionally, since the exact power requirements of a 5080 remain unclear, it's best to consider something more than 4080 unless there are clear indications otherwise.
It seems there isn't a store in Brazil that carries this 12VHPWR adapter. It's not possible to import it either. Could you have another idea?
it should be included with the graphics card, not the power supply. when purchasing, you'll find it in the box dedicated to the graphics card. for example, with the Zotac 4080 Super, the adapter is provided and can be seen in the images here: https://www.newegg.com/zotac-amp-zt...-r...6814500583
