possible problem with new GPU

[jk123]

Hi everyone,

My setup and what happened

Abit ip35-pro, Q6600, 8800GT, 4GB Ram, Win vista 32.

I swapped out the 8800GT for a GTX460.

Uninstalled old drivers, fitted gpu, booted successfully, installed new drivers, rebooted successfully.

While it was loading the desktop and doing some other stuff it switched off. Now after i power it on, switches off again after about 5-6 seconds.

Anyone had anything similar? Could it be the PSU not having enough juice? If thats the case why did it boot and load properly with the new card installed?

Any help greatly appreciated, thanks in advance

What PSU do you have at the mo?

Was your system overclocked at all?

Try a CMOS reset.

I think it could be the PSU! The 8800GT has one 6 pin to run off but the GTX460 has two which means it will require more power to run and will be more power hungry when running under full load.

Don't use Molex > 6 pin adapters, they suck ass!

Only use 6 pin adapters that run straight off the PSU!

If you need a new PSU go for the Corsair Builder Series CX 500W. These are great PSU's and are 80 plus Bronze, so they will not lose or waste power and produce loads of wasted heat.

Hope this helps

Hi, thanks for the replies.

Im on the same comp now and its stable.

After some trial and error the PC powers off when I run a GPU crunching app BOINC. So i think it might be my PSU not having enough juice for the card.

The rig I have is an OCUK gaming one from a few years back (see hardware in OP).

Pretty sure it was a top end branded PSU from back then. Either way, looks like I might need a new one.

Yea "back then" Newer gpu's will require more up to date PSU designs to run smoothly.

Get the builder series psu which I linked in my last post. It will serve you well for a good couple of years.
