Im getting a nvidia gtx 560 non ti graphics card to play battlefield 3 on. My power supply is only 450 watts. Is that enough to power my new graphics card?

Hello my friend,
the quality of the psu is always more important than the amount of wattage.
what's your psu brand?

Im not sure what brand it is because there is nothing on the psu, it just has 450 watts writin on the side of it.

If you have a power supply with nothing but 450w written on the side it's very likely a piece of junk. There should be a sticker on the side with voltage information. Post those numbers.

Open your case and look at the power supply, it should show the information on it.

Where did you buy this PC from?

Nvidia recommends a 520w power supply for a system with a single GTX 560.

http://www.realhardtechx.com/index_archivos/Page362.htm

That assumes a "generic" ( junk ) brand power supply.

The Corsair CX line is good but for around the same price you can get a much better unit that is fully modular.

$59.99 after rebate + an extra 20% off with code PCPBTS15 good until 8/26 makes this an amazing deal. It's made by Seasonic ( a very good thing ) and very highly rated.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Even though the PC Power and Cooling and Corsair are both rated as 500w models the PC Power and Cooling unit is stronger as it supplies 38 amps on the 12v rail and the Corsair only supplies 34 amps. The 12v rail is where a modern computer draws almost all the power it needs. The PC Power and Cooling model is also 80+ Bronze rated so is slightly more efficient than the 80+ rated Corsair.

I agree with the above, if you live in US it's very worth getting that power supply before the $20 off deal ends.

That's the RTX reccomendation
Nvidia's "minimum requirement" is 450 watts

Good catch. It's just such a handy list I forget that it's not always identical to what the manufacturers recommend. :D 


The power supply I recommended above is still a great choice for a great price OP.

I'd get a Corsair TX 650 v2 which will last for a few upgrades if the PC P&C isn't available.

For a system using a single GeForce GTX 560 graphics card NVIDIA specifies a minimum of a 450 Watt or greater power supply that has a combined +12 Volt continuous current rating of 24 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) @ 50°C ambient temperature, is the most important factor.
