I am currently building a new PC and need to get a power supply.
I will have a geforce 560 and an i5
I used calculator that calculates the wattage and it came to 550W so I was thinking a 600W.

The original PSU that I was going to go with was:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

On another post some one had told me not to go with cooler master as they are not a name brand and that name brand matters.

(in my mind I always thought that they were)

Now I know that name brand matters and you don't want to get a cheap one either they said to get a antec or a corsair.

So my question is is that a good power supply? Should I be looking for something else?

As I know not to get a cheap PSU I would like to keep it relatively cheap.

I do like the modular PSU's but that is not necessary.

Thanks

Learning can be fun and very useful! ;)  It's not just total watts that count in a PSU, it's also 12v rail amps.

You can accurately determine what PSU power is required in both watts and amps. on the 12v rail for your current or future PC build from the link below. It will also show you how to determine which model PSUs are quality PSUs that can deliver the necessary power for your PC if you need a new one.

Cooler Master is certainly a name brand (there's the name right there!), but it's not a reputable one. You'd probably be fine with a CM PSU, but they have a reputation, well-founded or not, for failing.

I'd recommend the XFX modular PSU as I have one myself.

Hasn't caused me any trouble the 7 months I've had it and ofcourse, cable management is alot better.

I read this forum and am more confused now.

Is 600W too much for this or will it be fine.
I used to different wattage calculates
one told be 550W the next said 450W
when looking at my graphics card is says 450W or grater.

I cant find anything about AMPS when reading about the power supply

Thanks

^^^^ The PSU you selected shows 40 amps. on the 12v rail. Look at the OUTPUT in the DETAILS tab at the link below. There is no such thing as "too much power" though an excessively large PSU is a waste of money and can be inefficient if under very light load.

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

The link I posted several posts above shows you how to find the power required for your 560 TI under max load which is 202W. 202/12 = ~17 amps. + 15 amps. for general system use + 5 amps. for a PSU safety margin so you are not at 100% of the PSU's power = 37 total amps required on the 12v rail. Thus as long as your PSU delivers 37+ amps. at 50C you will be just fine.
