so what is the exact power comsuption in watts of the nvidia 7600gs and ati 2600 pro then please

[avengeda7x]

as far as i know both them card dont draw exrenal power, all is consumed from the slot itself, so i would think you will be safe with a 450/500W

[nitrous123]

what would happen if I buy these graphics card under non-compatible power supported?

[mowersman]

try this one
you will be fine with a 400 watt psu

to your question...

im asuming you mean if you put in a graphics card with a minimum support of 500W and you use a 400W for example...

your system will be unstable, meaning that at anytime your psu could just *blow* and could take your motherboard with it as your asking for power that it cant supply.!

[nitrous123]

Wow shocking I'll get the 400watt power supply then. When I get some extra cash

[avengeda7x]

and another thing, its not all about watts when a psu is concerned.!

a good 400W psu could perform better that a cheap 600W

always cheak the output Amps on the 12V rail, idealy your looking for around 18Amps +

or eaven 2 x 12V rails at 15Amps +

[Jackiefrost9]

With 2 12V rails don't pay attention to what it says each rail can provide, pay attention to the combined power. Some power supplies with 4 12V rails at 20A a piece can only supply 25A combined. If it does not list the combined output in Amps then it will list it in Watts on the sticker on the side of the case. To convert from watts to amps over a 12V circuit just divide the watts by 12.

Thank you guys I'll keep that in mind then its abit advanced but i'm sure i'll get the hang of it.

o i just found out my mobo is actually a micro atx so can i buy a normal atx power supply or buy a micro atx instead?

[Jackiefrost9]

That depends on the case, not motherboard. But an ATX will fit mid and full towers, so I'd go for that.

[nitrous123]

its big case like most cases it is not small. I believe that a normal atx motherboard can replace it. So i will buy a atx 400w power supply

[Jackiefrost9]

Alright, the one I linked to earlier will perform well. Just don't cheap out on it. Make sure it has at least 25 amps on the 12V rail. You will really regret it if you buy a cheap power supply and when it breaks it takes your new graphics card with it.

[nitrous123]

I bought a new card a 7600gt I did many researches on it for my PC as it is a agp system and it was the card out there that I know of that could run neally all the games fairly well. So today I put the card in and I bought in a 400W Octigen Power Supply But the card doesn't wanna know. Its a Inno 3D 7600GT. The specs on the atx power Supply is:

+3.3V, +5V, +12V, -12V, -5V, +5VSB
AMPs: 26A, 30A, 12A, 0.8A, 0.5A, 2A

All I want to know is will I have to buy a new power supply??
