So I use AMD RX580 graphics card, and this graphics card must be connected to 2x 6pin power supply. But because my power supply only has 1x 6pin, I wanted to ask you if the good idea is that I can also operate the graphics card with 1x 6pin. Because the PC started up without any problems, so far not a single crash. The only problem is that Minecraft Shader Mod is not working so well. Because when I go to Rewi Server and I'm in the lobby, I sometimes even get under 20FPS with shaders. What do you think, would a new power supply help? Do I really have to operate 2x 6pin?
Did you use an adapter solution or something? Because actually the graphics card should not run at all without full equipment. And NO, your fps have nothing to do with your power supply, there are only two states, so to speak: running or switching off or braising. 6 pins are basically enough for the card, it just has more than necessary.
That would at least be recommended… I can't tell you whether the performance is reduced by just one cable… As far as I know, the systems either don't start or the cards do absolutely nothing because the clock rates remain in the basement
"Do I really have to run 2x 6pin?"
Definitely. Even if it starts up and even runs with just one,
if the manufacturer installs 2 connections, operation is only intended for 2 connected PCI-E connectors. Both the bios with its power target
as well as the technically permissible micro tips assume 2x6Pin connected plugs. You can of course use an adapter like Zakalwe links it, as long as the NT can deliver this overall performance.
No, that's not a good idea.
If your power supply does not offer 500W continuous power and no 6 + 2Pin or 2x6Pin power connection, then you can assume that your power supply is not sufficient to supply the RX 580 permanently.
If necessary, you can adapt a 6 + 2 pin power connector to 2x6 pins. The other day I had already written the permissible performance for the connections in an answer.
An Rx 580 can require up to 200W of power.
75 W are permitted via 1x6 pins as well as via the PCI Express slot.
Therefore 6Pins are not enough for an Rx 580.
Yes, in theory. In practice, tests have shown that these specifications do not matter at all.
Roman (the farmer) does not test cheap China power supplies, at least as far as I know. He is very competent when it comes to good brands and high-end components.
Based on his question from two years ago:
Wouldn't it surprise me if he has a China plug as a power supply that doesn't have a 6 + 2 pin or a second 6 pin power connector.
These power supplies then have max 500W peak power which then ends in about 300-350W continuous power, and that would be too weak for an RX 580.
He tests everything. His test for "Battle of the cheapest" motherboards is also legendary. But I digress. I have no reason to assume that the questioner could have problems, since his system apparently works as it is, and I have already heard and read a lot, but never anything about defects due to overloaded PCIe cables. Power supply units often break, but not because they have not divided the power sufficiently.
Do the math. How many watts does the card need?
The PCIe slot delivers 75W and 1 6Pin connector also 75W, together they are 150W. Is that enough?
Don't have to. The card basically works with only 1x6, which is my 580 (XFX). Yours seems to be overclocked from the factory, and therefore the manufacturer has installed a second socket for the sake of stability.
If you would like to run it a bit slower, it could (theoretically) be done with just one connector - but then of course the manufacturer must also undo the overclocking in the card's BIOS.
Don't know which one you have, some also have 2 Biose to choose from, an economical and an overclocked one. My recommendation: connect both plugs as usual, but undervolt on the desktop (there are enough tutorials).
