Will this psu work with this video card?

You need a PSU with at least 30a on the 12v rail(s), so your PSU may not even run the card; it won't OC it.

That OCZ 550W unit has 2 25A rails, the rating on the graphics card is for the combined power of the rails, that unit has much more than 30A combined between its rails so you are fine and it should be able to OC it just fine too.

ok thanks, I have another queastion, I am not sure what connector's to use for the video card, I know it's 2 6 pin but the psu has different ones. with the cpu and motherboard connectors built into the psu there's a 6 pin connector then I have to use the connectors it came with and plug them into the psu for the rest, Do I use this 6 pin that's built into the psu, or do I plug 2 6 or 6+2 pin connectors into the psu and use them, or do I use one of each?

Yep! it has one of each type you need to use both connectors.
Just leave the 2pin part unconnected.

I have this power supply and I am happy with it and it should run the card.

to answer your first question, i have the 560ti with this PSU http://www.newegg.ca/Product/Product.aspx?Item=N82E1681... , which has 12V@25A and mine is overclocked at 930 coreclock and my computer stays on 24/7 never had any problem even though its overclocked, so you should be fine with room to go further.

as for the 2nd question, gtx560 requires 2x6 pin which comes with your psu, all you gotta do is connect the 2 x6 to your psu (that comes with the PSU package) and connect to the end of your 560 which is here in this picture http://www.newegg.ca/Product/ImageGallery.aspx?CurImage...

and if i may recommend i have the MSI one, its overclocked higher , its cool and quite can barley hear it and temps never go above 53 when gaming.

Your PSU is fine--much more than powerful enough to handle this. It has a combined 50A (two +12v rails at 25A each)

You added them, bad.


Note the combined power rating below them of only 450W, thats only 37.5A. Each rail will let you draw 25A if you are only stressing it, but the source that feeds them both will only provide you 37.5A, rarely can you just add rails because they tend to share a source.

Thank you for the clarification -- I only scanned the newegg post and was simplifying the math.

This does not, however, change the fact that the PSU can handle the card just fine.

i agree with deadlock, should be no problem running tha gpu with ur current power supply state
