Question PS help

[Craig234]

I think my PS, 2 years old went bad. Bout a new one corsair hx750i, unpluigged old, first thing I noticed, biggest plug is 9 pins long, old ps had a 9 pin slot but longest on new PS is 7 pins. MB is asrock extreme6. Help...

Motherboard?

 

[Craig234]

I found out the PS don't use standard cables so I need to either replace all the cables for power in the system, or buy a matching PS fr the original.

Corsair hx750i is standard ATX, it even has 2 24pin connectors. Your motherboard also has the standard 24 pin header. Not sure where your confusion is. Maybe using the wrong cables?

 

[Craig234]

No, the old PS was seasoinic gold focus; its cables donm't fit the corsair.

Ugh. have an old seasonic series x and thought that should have matching pins to the seasonic focus. It doesn't.

No. The psu is proprietary. All psus are, even models are different hookups at the psu. It's done on purpose to stop ppl adding extra cables where they aren't supposed to go.

You need to use the cables that came with the Corsair on the Corsair, you cannot use the cables that came with the Seasonic.

The only connectors you need worry about is the component end, not the psu end. If the Seasonic Focus Gold died after only 2 years, either its defective and is covered under warranty or there's an issue with the pc that caused a failure. Those units don't usually die in that length of time.

It's disappoimting even the same brand isn't compatible. If a PS is bought and unopened years, say 10, how degraded is it?

Replacing wiring is tricky, have to get several, miss none, get all right.

Not even sure it's PS. PC wouldn't power on at all but USB devices receive power. pC very dusty but MB vertical and not dusty.

Posting on PS4 big headache, backspace and enter exit text entry...

 

[Karadjgne]

It's not. Not really. Not until it's seem some use, or unless subject to abnormal temperatures.

Wiring is easy. 2 goto motherboard, that's it. Everything else is peripherals like maybe standalone drives, gpu etc.

You won't know if it's the psu until you get it hooked up, even a temporary messy hookup works. Wont know until it's done.

I don't use pc much, mostly smartphone for posting here.

Update: swapped the cables. PC now boots - except the graphics card has power to the LED logo, but no fan and nothing to the monitor, so I had to move the HDMI cable from the GPU to the MB.
