Author Topic: Can a regular 4 pin molex drive an AGP card? (Read 301 times)

My computer has stopped booting after a few warning signals. Regardless of whether I went into Windows or left the OS at the select user screen, the same amount of time would elapse before the machine would freeze. I then had to hard reset. It would usually boot from this point.

A couple of days ago this stopped working, and now I suspect the PSU to be dead.

The replacement I'm looking at is a PC Power and Cooling 750W unit, since it is recommended by Skuzzy as a decent manufacturer. However my MB is old and AGP. The graphics card needs a molex connector, but the PSU carries 6 and 8 pin PCI-E connectors. My old PSU had specific labelled molex connector for the graphics card. Can I use any molex plug from the new PSU?

My graphics card is an X800XT if that helps. Thanks for any advice.

Also I wrote this using a Wii controller, just so you appreciate the effort.

You can use the molex if the card accepts one. Usually they need a converter in between though.

I believe all 4-pin molex connectors are on the 12 volt rail, so they're all the same.

Dowding,

I use an AGP card also, mine is an ATI Radeon X800 Pro, and yes you can use any MOLEX connector , any of them will do the job just fine

the PCI-E cards use the 6pin and 8 pin PCI-E power connector only......

I had upgraded from my old ATI Radeon 9800 pro 128meg vidcard which also used the same type molex connector , to this X800( er 850 ) 256 meg AGP card.

let us know how it goes for ya

OH! I forgot to mention. As best as possible, try to give the video card it's own "chain." Meaning hook as little as possible into the wire that the card's plugged into. The more stable and correct the voltage, the longer the card will last and the better it will function. DO NOT put them on the same chain as a hard drive or especially an optical drive if at all possible...those things really suck some juice.

Thanks guys - reassured me that I had not bought something I cannot use.

I went for an OCZ StealthXtreme 600W in the end. It's not going to be stressed by my current system, and I plan on turning this machine into a HTPC when I build a new PC. I'll splash out on the PC Power and Cooling thing at that point.
