What amount of power is consumed by Nvidia GeForce GTS 450?

**Ga.One** · 04-12-2011

I wanted to purchase Nvidia GeForce GTS 450. But I am not having the idea whether the PSU will handle the same or not. Right now I am having Quoltec SilentLine 520W with the +3.3v-33A; +5v-33A; +12v-20A; -12v-0.5A; 5Vsb-2.0A and single 6 pin-connector plus. I wanted to know whether graphic card of mine is enough power form the PCI express slot and the 6 pin connector so that it can run good? Let me know if you are having any query on this particular matter.

Looking at the post of yours I wanted to tell you that the PSU which you are using is sufficient for the Nvidia Geforce GTS 450 which you are looking for purchase.

Thanks a lot for the prompt replies of yours. I wanted to ask further some questions. What amount of the watt will be left on +12v rail? Will this particular graphic card go for the full power with PSU? I am also wanted to purchase this card for Skyrim on the resolution of 1240x1080. Is that true that PCI Express slot will give some energy to the video card? Also is PCI express slot make use of +12v rail?

Well after going through the query of yours I wanted to tell you that 450gts is going to use the same amount of the power of 9800gt. If you really worried about the same then you should purchase the PSU of 750watt and you will not require to worry about the past couple of years.

In this particular situation I wanted to tell you that Core i3 CPU will draw 73W and GTS 450 will draw maximum amount of 106W. also I am assuming that motherboard and hard disk will take maximum amount of the 40W. the total power taken from the +12V rail would be approx of 219W which near of 18A. so it seems to be quit close to PSU which is having supply 20A max on +12V rail.
If the PSU is having continues power supply of 20A on +12V rail then you will not have the same problem. In case you have over clocked the component than there will be need of more power.
