One morning, my GTX 470 suddenly shows up artifacts during POST, which have never happened before.
I concluded it to be broken and looking for a replacement.

But before that I would like to ask, could it be that my GPU broke cause of the lack of amps on the 12v rail of my PSU?

My PSU has 26amps on its dual-rail 12v

So, since I'm planning to either RMA the card or get a GTX 560Ti, should I swap the PSU?

What brand and type would you recommend?

What is the PSU's make and model?

Also are you able to test the graphics card in another PC?

My PSU is a VenomRX Red Diamond 650W
It is a local brand here in Indonesia.

I'm not yet able to test the card on another PC because my other PC's case is not large enough for the
GTX 470.

I might just remove the motherboard and test it outside the case, but I haven't found the time to do that.

I take it that's 26A for both +12V rails combined?

Lets say that your PSU can supply both +12V rails fully at the same time, that gives us 26 x 12 = 312W which isn't alot considering almost all of your PC's components get there power from the +12V rails.

A GTX470 is a power hungry card, I wouldn't trust that PSU to power it.

Actually 26A is one rail, so in total i have 52A

It doesn't work like that, you can't just add the rails together to get the total.

I stated it like that just to correct omgitzfatal's misinterpetation of 26A as the total amps available
