    Pin Square
AI Thread Summary
Upgrading a computer with an MSI K9N SLI V2 motherboard and an AMD Athlon 64x2 4600 CPU requires a 12V 4-pin square power cord for the CPU, as specified in the motherboard installation manual. This connection is essential for proper functionality, as the system may only power cooling fans briefly without it. If the existing power supply unit (PSU) lacks this connector, it is necessary to upgrade to a compatible PSU that meets the power specifications for the new motherboard and CPU. Additionally, an extra 4-pin Molex connector may be needed to supply power to the CPU or graphics card. Upgrading the PSU is crucial to ensure adequate wattage for all components.

Hi There Please Anybody Than Can Help
I Am Upgrading Computer Running Into Problem

If the installation manual says you need it you probably need it.

An extra 4 pin molex is sometimes needed to give power to the CPU or graphics card. If you're using a standard ATX power supply there should be a few extra connectors there.

Yes, you really do.
They changed the power supply specifications several years ago.
You need to upgrade to power supply to match the new mobo.
 
Always upgrade your PSU if you upgrade the motherboard and CPU, especially if the existing one doesn't have a 4pin connection.
 
You might also need a new PSU because it can't give your components the wattage they need in the first place.
 

Thread 'Is AI hype?'

In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...

Thread 'MS 365 Profile Badge colour'

Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
