GTX460 problem, PSU to blame?

[Nyoron]

So I finally got myself an Asus GTX460 1gb to use temporarily in my aging Socket939 pc while I save up for the rest of my new build.

I get BSOD about 5secs after booting into windows xp with a nv4_disp.dll error.

Uninstalled, reinstalled latest drivers several times (safemode, driversweeper etc) without any luck. Old gpu still works fine.

I am begining to suspect my 4 year old Seasonic S12 500w psu is to blame. Reading the box of the 460 it says it needs a 12v current rating of 42a, psu box says 12v1 17a 12v2 16a for a total of 33a(?).

Would i be right in blaming the psu? or am I reading it all wrong?
Just want to make sure before I cough up the cash for a new psu.

Thanks.

scotty365: both pci-e connectors are in, tried with bare minimum but still bsod.

Ejizz: you may be right, I was pretty sure beforehand that I could run a 460 on this psu. I will see if theres a new mobo bios(I have an Asus mobo btw)

Thanks for the replies guys.

I meant to check with Gigabyte to see if they have an updated Bios for your graphics card.
Won't hurt to update your mobo as well though.

I know it's late at night but....the graphics card is also an Asus. (see my first post )

Anyway, it turns out I'm already using the latest mobo bios, no new bios for gpu.
I just tried using the 2nd pci-e slot after reading a few success stories, no bsod(!) but the screen flashes black intermittently and the whole system freezes if i try to open a video.

I'll see if I can try the card in my brother's pc and borrow his psu tomorrow.

drunkenmaster: Thanks for the comprehensive reply. It only crashes once the drivers are installed and rebooted, I am using the latest nvidia driver(258.96) for xp32bit.

It hadn't really crossed my mind to try older drivers because support for 460 has only been added recently but i'll give it a go anyway until I can access my brother's pc.

I think the card itself is dodgy, tried it in brother's pc (win7 64bit, 550w corsair psu) same problems.

Rma time.

Thanks for all the replies.
