PSU Advice needed

Hey guys, well recently I sent back my 7900GT as it was starting to die and in return I got a nice 8800GTS. However I have a feeling my power supply is just not up to scratch. It’s a Tagan 420W:http://www.pcmoddingmy.com/e107_plugins/content/content.php?content.235
Now the reason why I know its not up to scratch is because when I play games such as Live for speed the card runs fine yet when I run the CSS stress test a coloured screen appears(it has show both a light blue and a grey screen) and nothing responds.

At the moment (now try not to laugh too much

) I am running an AMD 3500+, 2GB ram, 1x HDD 1x OD and a XFX extreme music sound card.
What PSU would you guys recommend? especially something which will run with these components which i will soon be buying:http://www.overclockers.co.uk/showproduct.php?prodid=BU-068-OK&groupid=701&catid=339&subcat=1026

I would prefer it to be as cheap as possible while still being a decent enough PSU.(note that i dont overclock)

Cheers.

Thanks for the reply, at first I was a bit hesitent with that power supply but from reading a few reviews it seems to hold it's ground, i may consider buying it.

The Tagan should be giving plenty of power to that system so I doubt is your PSU.

Well I assumed it is as when I had my 7900GT in there it never crashed and was running smoothly (up until the point it died of course).

Hey guys, heres an update on the situation:

I went for the corsair PSU and installed it but I get the same problem :confused:

Now after the loading bar disappears on the CSS stress test it runs fine until you get to the water part and then the screen turns into a colour (so far black, grey, blue and purple...) and the computer wont respond. Even when I press the restart button on the computer that same colour remains so I have to completely turn the computer off.

What I also noticed is that when I play a game such as oblivion on medium settings the game runs fine but when I turn the settings up I have the same scenario as described above. I tried using my old 6600GT just to test it and it worked fine so I have no idea whats wrong.

Hey, well what I done was uninstalled the driver (while I had the 8800 in) and used a driver sweeper programme to delete any remaining files and reinstalled the latest nvidia driver. The case that I use is a Thermal take Tsunami, which has a front 120mm fan, a rear 120mm fan and a side 80mm fan. Unfortunately I can’t test the card in another system and I get the same problem on any game which puts the card under any load. (Like css/oblivion)

Aye, I will bug my friend tomorrow and ask him to test it on his.

Hey guys, well a quick update. The card was indeed faulty as I tried it in my mates computer (he runs an 8800gtx, e6600). Thanks for the help guys, eventually got to the bottom of it.
