Question why doesnt Corsair RM1000x have 2x2 power socket?

[Richard1234]

Hi,
I bought an RM1000x PSU by Corsair some years ago, which is a 1000Watt ATx PSU.

I thought ATx was a standard, so I could just use it to replace the PSU of the PC I built in 2010.

fortunately, I decided to replace 1 output power cable at a time from the old 550W PSU, and right with the first power cable I ran into a problem.

The 2010 motherboard has a 2x2 socket, marked with a green arrow in this photo:

where the RM1000x doesnt have a 2x2 output cable. The RM1000x has lots of sockets on it, and lots of double ended cables, which you insert at one end to the RM1000x and at the other end to the motherboard.

I then had to just reinstate the old 550Watt PSU


I thought as ATx is a standard, I could use any ATx power supply with any ATx motherboard.

thanks for any help
Richard

It absolutely does have necessary cables.
2x2 is called 4pin CPU power cable (ATX 12V 4pin). Nobody calls it 2x2.

4pin CPU power plug you can get from 8pin CPU power plug. It can be split into two plugs.

It does have multiple 4-pin CPU cables. They come in doubled up 8-pin where you have to split them apart.

thanks for the prompt reply! I just pull that apart at the middle?

looking at the photo I gave, it looks like the left half of your photo above?

can any ATx component of any era be used with any other ATx component of any other era?

eg an ATx PSU from 2010 be used with an ATx motherboard of today? (subject to power demand)
and say an ATx PSU from today be used with an ATx motherboard of 2010? (subject to power demand)

I can see that say a specific motherboard will only be compatible with a few series of CPUs, and a graphics card would need the specific slot, and a memory card will only work on some motherboards.

I dont know if the ATx standard just relates to the tower case, PSU, motherboard, where say the graphics card slots and memory card slots dont relate to the ATx standard?

Physical connections would be compatible. Yes.

Power demand is determined by components installed.
So - No. Any weak 250W PSU will not be able to provide enough power to a high power gaming pc
(like with 450W RTX 4090 inside).

ATX standard covers

PC case dimensions,​

motherboard dimensions,​

PSU power delivery and plugs.​

​

Modern graphics cards are covered by PCIE standard.
Modern ram is covered by DDR standard.

is power the only problem of connecting arbitrary ATx things?

I had been having problems with my USB2 wireless, where the sonar symbol will vanish from the desktop and no internet, then if I remove either the wireless adapter or the hub and then reconnect, it then can reappear.

I have a lot of stuff attached to the computer, eg solid state drives via motherboard SATA sockets, and I thought it might be the power.

when I then reconnected the old 550Watt PSU, where the cables come directly out of the PSU and arent double edged like the Corsair, I also removed the sound card in an attempt to reduce the power usage, and I have had less problems of the wireless vanishing. But it still does vanish.

I will try reconnecting the 1000Watt Corsair, originally when I reconnected, after photographing the socket, I forgot to reconnect that, and I got no video image! Eventually I thought it might be that 2x2 socket, and reconnected that cable and the video image returned.

I just dont know if the USB2 circuitry can wear out? or is the wireless vanishing more likely to be insufficient power?

I noticed also that with the USB sockets of the computer, some lead to much slower speeds of webpages loading, I dont know if some USB sockets are USB1?

if USB2 is backwards compatible, I dont see the point of having USB1 only sockets.

I did buy a USB3 card once, but I found whenever I used hires graphics, namely some pixel perfect HD screensavers, the machine would crash. Examining the machine, I noticed the graphics card got really hot, and it was next to the USB3 card, and suspected the heat from the graphics card was causing the USB3 to malfunction, or maybe just used up too much power. Removed the USB3 card, and no further problem.

if the USB2 circuitry is deteriorated, I dont know if I can arrange USB2 via a card via the other card sockets?

I need to build a brand new PC with everything modern, but as a temporary fix it would be nice if I can get the USB2 functioning.
