GPU power question

[Tubbehh]

I just ordered everything for my new computer and i got this video card and power unit

I just making sure that that power unit is enough to power the gtx 760

It is plenty! the recommended size for a system with a single GTX760 is 500watts and that is not based on units with that quality http://www.realhardtechx.com/index_archivos/Page362.htm

ok, i just got confused because it says the gtx 760 needs "a minimum of 30 amps on the +12 volt rail", and Im not sure what that means.

That PSU has 44 amps available but some less than good 500watt units would hardly meet the 30 amp requirement.

so you are saying that my power unit is fine and has over 30 amps on the 12 volt rail thingy?

 

[rolli59]

Yes it is and is an excellent choice because it is a quality unit made by Seasonic. Here are the specs on it http://products.xfxforce.com/en-us/Power_Supplies/Pro_Series_550W_PSU/P1-550S-XXB9

ok thanks and i have one more question, it says it needs at least 30 amps on a 12 volt rail, is the rail a certain thing i have to plug into the video card, I know I have to plug in the 8 pin and 6 pin plugs( actually Im uncertain, do i have to plug in both of those because i installed a gtx 650 ti on my old computer and i think it just had a single 6 ping connector if Im not mistaken).

The rail is how much power the PSU can deliver at +12 volt DC to all components. Every yellow wire coming from the PSU is 12 volt. The PCIe power connectors are on that rail and you will have to use them both.
Good info on PSU connectors and voltages http://www.playtool.com/pages/psuconnectors/connectors.html

 

[Tubbehh]

thank you very much for all of the help

 

[rolli59]

You are welcome.

ok i see, so on the gtx 760 i need a 8 pin and 6 pin so depending on the number of yellow wires the 6 and 8 pci express pin has it will deliver that much power to the video card

 

[rolli59]

6 pin connector 75 watts or 6.25 amps 8 pin 150watts or 12.5 amps.

 

[Tubbehh]

wait so do i have the required 30 amps for the video card?

 

[rolli59]

The required specs for the GPU is for the total system, or 500watts with minimum 30amps on the +12 volt rail! Here is total system power draw measured with a GTX760 and it comes to 336watts gaming! http://anandtech.com/show/7103/nvidia-geforce-gtx-760-review/16 That is all the components!
