Evga Power Supply Review

Every Pc enthusiast owns or wants to own their custom Pc. The process of finding the different Pc parts, which are available in abundance can be very time-consuming, but, at the same time, engaging and interesting, because you feel that you’ve created something on your own.

Some parts inside a custom Pc are more overlooked than others. Probably the most overlooked Pc component is the Power Supply. We tend to just buy the cheapest one, in order to fit other “more important parts” into our budget, like the graphics card and Cpu. Guess what: The power supply IS the most important part of a system, as it delivers power to all components. If you want to get to know the basics of how to choose a proper power supply for your computer, check out this post:


Now onto the actual product: Why have I chosen the Evga Supernova 650w 80+Gold as a product to be reviewed?

10 Years Warranty

10 Years Warranty

Evga is certainly the best company when it comes to producing top quality power supplies.They have won over 70 awards from leading review sites. Their 10-year warranty, additionally, ensures that they are pretty sure about the quality of their product. The supernova G3 series builds upon the already excellent G2 series of power supplies, which have gotten impressive reviews over the past few years. Moreover, their customer support is top-notch, meaning that you’ll never have any problems finding an EVGA representative either through E-mail or through the phone.

I personally have a Supernova G2 650w power supply installed in my system and I have had no issues whatsoever. Two years now I never had a power delivery failure or heard any strange noises coming from the power supply itself. If I were to purchase a power supply right now, I’d go for the G3 series hands down. Better to be safe than sorry with power supplies. Power supply failure could burn out my whole system.

Instead of telling you about my own experiences with Evga’s power supplies, I’m going to analyze the specs of the PSU, so that you can see for yourself how good it actually is.



  • Evga’s G3 series of power supplies come equipped with all safety measures to ensure good power delivery. Characteristics like Over Current Protection (OCP), Over Power Protection (OPP), Over Temperature Protection (OTP), Over Voltage Protection (OVP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), ensure that there be no problem with temperatures or overvoltage of your power supply. You should also be on the look-out for these terms , as they are indicators of a top-quality product.


  • The power supply is fully modular,

    which helps a lot when trying to do cable management, as you don’t need to install unnecessary cables. Less cables to deal



    with mean less time building the Pc and better air flow. If you want to clean the power supply once a while, you can do that easily by simply removing the cables from the PSU. The package comes with 2 PCIe cables, 3 Sata cables, 1 4-pin peripheral cable, 1 floppy adapter, 2 Eps cables as well as 1 Atx 24-pin cable so you don’t have to worry about connectivity issues to your motherboard or any other component. Everything is included. 


  • EVGA have improved their Eco Mode, which makes their G3 series power

    Super-silent fan

    supplies super silent, even on high load. The hydraulic dynamic bearing fan, also ensures that the PSU is almost inaudible.  They say it is even quieter than their G2 series, which I can barely hear inside my rig.


  • The 80+Gold certification ensures 90-92% power efficiency, which has a positive impact on your monthly electricity bills. If you want to know more about the 80+certification and what it actually means, check out my post by clicking here.

There are trusted brands within the Pc hardware community and every brand is known for something specific. Asus produce excellent Motherboards, Msi have top notch Graphics cards and Corsair is the leader of mechanical keyboards and Ram sticks. These are just examples, of course. Just think of this: Would you ever buy a cpu that is neither from Intel nor from AMD, if there was another new company? I bet that most of you wouldn’t. This same principle applies to all the other components. Why would anyone buy a power supply from an unknown brand or even a medium quality one from a known manufacturer? Believe me there are many bad power supplies out there. Even if you don’t want to pay a little bit more for the premium features of EVGA’s Psus, at least make sure that the one you buy is on the Tier 1 or Tier 2 list of Power Supplies listed here

Linus Tech Tips has provided an excellent list of premium power supplies in the Tier 1 and Tier 2 category. I recommend never purchasing anything below Tier 2, because the quality of the Psus is starting to decrease after that.

Final Thoughts

One can easily get confused with all the different power supplies out there. It is crucial to understand the key features a Power supply should have before buying one. Check out my post for more information on that. Cheap price equals cheap performance most of the time. It is never a good idea going cheap on power supplies. You may spend more money now, but in the long run, you will be compensated for that by your low electricity bill and the stability of your system

Providing good, constant power to your precious Pc components is something only a good power supply can ensure. With EVGA I can ensure you that you will not be disappointed. Even if something goes wrong ( there is always a possibility) the 7-10 years warranty will make up for that, as EVGA is pretty sure that their power supplies are The Best out there. And I can personally confirm that.


I hope you liked my review. If you have any questions you can contact me on or simply leave a comment below and I’ll be more than happy to help you out.
