What PSU to use with GTX 1060 6gb

Solution


As I said before, you could technically run that card with a 450W unit just fine. The problem with choosing a PSU in that wattage range is that they tend to be less reliable and cheaply made. Also, it is a standard practice to install a PSU in your system that has more wattage than you really need. This allows for the unit to not have to run at it's maximum capacity. If you get a 400W unit and your system is pulling 300+ watts from the wall then you are pushing that cheaper PSU to it's limit more often. You will not have the reliability you would have with...
For that card, Nvidia recommends a 500W unit. I have a 1060 and I use an EVGA 650W 80+ Gold PSU to allow for plenty of overhead space.

The 450W unit you listed from Amazon would technically run your system but not efficiently. I would recommend a PSU that is at least 550W with an 80+ Bronze or higher rating. You can scale up or down a little bit if you want to (give or take 50W).

I would recommend this one: EVGA Supernova 550W G3 80+ Gold

Again, if you want something cheaper you can drop down to a 500W unit with a bronze rating. Avoid "white" ratings or any other PSU without an 80+ rating.
 
Then I would suggest cross referencing what you can afford with this list and get one from as high a tier as you can manage, but for safety's sake as recommended by JW look for something 550W or more and bronze rated as a minimum.

You will not have the reliability you would have with a PSU that can handle more throughput.

However, if you want to stay under a certain budget and you simply don't mind the cheaper units, then you could use whatever unit you want that suits your needs and budget. Just know that the PSU is more likely to die sooner and not have as long of a warranty attached to it.

Any and all PSU's are susceptible to failure from the crappiest to the best. It all depends on the quality of the parts and manufacturing. Even 1000W Platinum units can fail out of the box.

The odds of a smaller wattage unit failing are higher than that of larger, better rated one but those odds are still very small. If you went with the Corsair unit then you would be fine. PSU's would much sooner fail/die rather than "blow up" and damage your system. Sometimes, however, if a PSU fails a certain way it can take other components with it. It's just the risk you take anytime you build a system.
