EVGA Supernova G1+ PSUs shine with refinement

We've always held EVGA's Supernova G1 power supplies in high esteem. They're high-output, fully-modular, high-efficiency, and not too expensive. Nevertheless, EVGA decided some improvements were in order, so now the company is shelving the G1s and bringing out the Supernova G1+ series. On the surface, the new models are quite similar to the last-generation hardware, but EVGA has made a few changes worthy of note.

The biggest difference is in the size of the new units. The original Supernova G1 PSUs were either 7.9" (20 cm) in length for the 1000W models, or 7.1" (18 cm) for the 750W and 650W versions. The G1+ series shrinks slightly across the board, now measuring in at a length of 7.1" (18 cm) for the 1000W and 850W variants, and 6.7" (17 cm) for the 750 and 650W models. It's a small difference, but on fully-modular power supplies like these, the reduced dimensions can really help with cable management.

The other big change in the G1+ series is the move to a fluid-dynamic-bearing fan. EVGA claims that the new fans last longer and make less noise than the ones in the original Supernova G1 units. The fan shares the same size as before—135 mm—but it could offer more reliable performance. 

EVGA also talks up some improvements to the new supplies' guts, such as the move to a single-rail design, the switch to 100% Japanese capacitors, and what it calls a Variable Resistor module. While the company says that the changes add up to a more efficient unit that supplies more stable power, these units' efficiency certification remains the same at 80 Plus Gold—not that that's anything to complain about.

Newegg already has the new EVGA Supernova G1+ units in stock. You can pick up a 650-W G1+ for $110, a slightly more capable 750-W unit for $120, a beefier 850-W PSU for $150, and the big daddy 1000-W model for $190.

    Not that this is a bad PSU but I still prefer the Focus Plus for the 10 year warranty and 0% fan mode.

      EVGA has the same thing since their G2 series (maybe even earlier)

    The G1+ seems like a lower end than units like G2 and G3. With G2, they moved to a better platform. G3 is an improvement over G2.

    I’d still prefer the G2 and G3 over G1+ and pay extra $10.

    Also, G3’s aren’t the quietest. The Seasonic units are quieter when the fan is on. Whatever marketing speak they say for the FDB fans aren’t worth much. At least the circuits running the power supply are top notch.

      I’ve never heard my PSU fan over my GPUs and case fans. What kind of PC are you talking about? (intended purpose)

        I’ve read many forum reports of people saying G3’s fans aren’t the quietest. The big thing about these power supplies are that the Hybrid mode allows it to run at zero RPM. That won’t be the case when its over 50% load.

        If you have the smaller units like the 650W, you’ll get over 50% load with a high end system quite easily. The PSU fan runs about as loud as an aftermarket GPU’s fan at normal 3D loads. Of course with GPU fan settings you can change when it runs, and what RPMs it should run at.

        It’s not a deal breaker but don’t take marketing speak for granted.

    What was the model progression?
    G1 –> G2 –> G3 –> G1+

      That’s correct. Maybe some country has silly superstitions with the number 4?

        So long as they continue to create quality products, I don’t give a rats arse if they do have a silly superstition related to the number 4 and death.

          Completely Agree!

          I have said it before and I will happily say it again. I am currently running a 1000 Watt G2 that I got several years ago now, and it is still an excellent power supply that is also STILL under warranty because EVGA warranties these things nearly forever!

          It really IS hard to get super excited over power supplies… but that being said… I really am one very happy customer with regards to the EVGA PSU I bought. If I ever need another mid range or high wattage PSU again in the future, EVGA’s units will definitely be at the top of a very short list for me.

            SeaSonic should be at the top of your list. A model like the [url=https://www.newegg.com/Product/Product.aspx?Item=N82E16817151192<]$99[/url<] SeaSonic [url=https://seasonic.com/focus-plus-platinum<]Focus Plus Platinum SSR-650PX[/url<] is a good unit for most gaming PCs.

            They are on that short list as well. The top 3 in consideration for me right now woukd be evga, seasonic, and corsair

            Funny enough, evga and corsair don’t actually make PSUs. The sell and warranty them, but all their units are made by someone else. Some of the good ones are made by (wait for it…) seasonic.

            If your PSU list is only one item deep, it will be populated with Seasonic, every time.
