I recently got a Palit GTS 450 to replace my 9500 GT. I installed the card, plugged in the 6 pin cable, turned on the PC and when the windows loading bar comes up I get a blue screen flash up for a second. I don't have enough time to see what it says. I'm back to using my 9500 at the moment without any problems.
So I did some searching on the web and I think its likely that the problem is my power supply.
the GTS 450 box says: Minimum 400W with a minimum 12V current rating of 22A.
My power supply says 450W with 12v and 20A.
I just wanted some advice to make sure it is the missing 2A that is the problem before I buy a new power supply as to a Pro the problem could be obvious.
If anybody needs more info on my system say what you need and how I can find it and i'll get it ASAP.
Its very likely to be the PSU, 20A or 240W (20A * 12V) is very low for a 450W PSU, I assume the PSU is old?
Modern PSU's have almost all of there wattage on the +12V rail(s) because modern PC components use the +12V rail(s) unlike older PC components that use the +3.3V and +5V rails aswell.
So basically I think your PSU isn't up to powering a modern PC.
Its REALLY important to buy a quality PSU, its the most important part of a PC. Worth spending a bit extra for quality
BTW I'm pretty sure all PSU's have a +3.3V and +5V rails, what I mean't before was that older PSU's have alot of their power on the +3.3V and +5V rails, where as modern PSU's have almost all their power on the +12V rail(s).
As modern components use mainly the +12V rail(s) its important to have a PSU with most of its power on the +12V rail(s)
