How To Choose the Best Power Supply Unit

Of course, everything that is mentioned above will be useless if you do not know the general idea of looking for a power supply unit for your rig. So here’s a guide on how to choose one.

As you may have noticed, the term 80 plus is pretty common in this list. This term actually denotes the energy efficiency of the PSU. Here’s the exact value:

  • 80+ White – 80 percent power efficiency
  • 80+ Bronze – 85 percent power efficiency
  • 80+ Silver – 88 percent power efficiency
  • 80+ Gold – 90 percent power efficiency
  • 80+ Platinum – 92 percent power efficiency
  • 80+ Titanium – 94 percent power efficiency

Generally, a power supply unit that has a rating of 80+ gold or above is the best choice. Choosing the wattage of the PSU , on the other hand, is a different story. You just don’t automatically go for the highest wattage. High wattage power supplies for most rigs aren’t really necessary.

Sure, there’s a certain ring to it when you say you are using a 1,200W power supply unit (PSU) in your system. But unless your rig is using multiple GPUs, or overclocking crazy high-end CPUs,  a 1,200W PSU is just overkill.

That’s because your system will not be running at maximum power all the time. Usually, it idles at around 80W. That’s a bit of a gap, isn’t it? The only thing you are getting with a higher value is more headroom for more stressful scenarios.

So, in order to pick the right wattage for your power supply unit, you have to know how much you actually need. The best news is, there are actually tools online that can help you search for the best power supply unit. For example, EVGA has its Power Meter.

EVGA recommends products from its range. What it does is it asks you a few basic questions like how many drives you have, what type are those hard drives, what CPU and GPU you’re using, etc.

After finishing the questionnaire, it will recommend a specific PSU for you. Lastly, aside from the actual power rating, you will also need to make sure that the PSU that you will use can provide the right connectors to connect all the parts of your rig.

We recommend you use a modular power supply because generally, you will only have to attach the cables you’re going to need. A modular PSU is easier to handle with and will look cleaner after setup.


As you can see, there are several PSU that can provide ample power for your GTX 1080 Ti. The seven choices above all have enough juice to power at least one GTX 1080 Ti.

And as you might have noticed, the reason why they are the best power supply for that GPU is that because they are very efficient. Another qualifying factor is its price range.

Cable design and aesthetics only come as secondary factors when considering the PSU to use.

So all in all, these seven power supply units are the most affordable PSU in the market today that will be able to provide enough juice for your GPU and still have plenty of headroom just in case you decide to upgrade to a higher GPU. Hopefully, by now, you have chosen the best power supply for GTX 1080 ti for you.
