Introduction and Features


View Full Size

Small size, big performance – the new Supernova G3 Series power supplies are based on EVGA’s popular G2 series but come in a smaller chassis measuring only 150mm (5.9”) deep. The G3 Series uses a 130mm cooling fan with a hydraulic dynamic bearing for quiet operation and EVGA claims the G3 units offer even better performance than the original G2 models. The Supernova G3 Series is available in five different models ranging from 550W up to 1000W. We will be taking a detailed look at the Supernova 750W G3 power supply in this review.

•    EVGA SuperNOVA 550W G3 ($99.99 USD)
•    EVGA SuperNOVA 650W G3 ($109.99 USD)
•    EVGA SuperNOVA 750W G3 ($129.99 USD)
•    EVGA SuperNOVA 850W G3 ($149.99 USD)
•    EVGA SuperNOVA 1000W G3 ($199.99 USD)

Here is what EVGA has to say about the new Supernova G3 power supplies: “EVGA SuperNOVA power supplies are well known for their extreme efficiency, performance and reliability. In fact, over the last 3 years EVGA SuperNOVA power supplies have won over 70 awards from leading review sites. It is EVGA’s dedication to performance that has created the latest power supply platform; the EVGA SuperNOVA G3 Series. With these new power supplies, we take the best features from our award winning G2 lineup and make them even better. The SuperNOVA G3’s smaller size, improved performance and a new Hydraulic Dynamic Bearing fan give you ultra-quiet performance and an increased lifespan.

A reduced size does not mean reduced performance with the EVGA SuperNOVA G3 power supplies. At only 150mm long, this makes these some of the smallest power supplies on the market today, while offering improved performance and features.

EVGA was founded in 1999 with headquarters in Brea, California. They continue to specialize in producing NVIDIA based graphics adapters and Intel based motherboards and keep expanding their PC power supply product line, which includes over forty models ranging from the high-end 1,600W SuperNOVA T2 to the budget minded EVGA 400W power supply.

Who is the actual manufacturer? Do EVGA produce it themselves or they are partnering with Seasonic or CWT etc ?

"Here are a few pictures showing the layout and components inside the EVGA Supernova 750W G3 power supply. The Supernova G3 Series is built by Super-Flower and is based on a second generation Leadex platform."

Have the powersupply manufacturers ever standardized the modular connectors? I have a bunch laying around that I am too chicken to try.

Hi, I asked in the office chat and unfortunately the answer is no. The modular connectors are not standardized between manufacturers or even between PSUs from the same manufactures (sometimes you can swap them within the same line but not always).

Good review!

Question: how well does this compare to the Seasonic Focus Plus series (SSR-750FX) in your opinion? The F+ kindasorta won by a slim margin in JohnnyGuru's testing, but their rating system is a little... eccentric.

Obviously they're both awesome units but if you had to choose...

I've been a SS loyalist and pricing on the F+ series is very competitive, but there was some concern with the F+ units' small fan resulting in annoying noise.

Another question: what's the benefit of a fully modular PSU? Do they expect people to run their PSUs without the ATX12v cable? Is it just for easy-ish replacement if you happen to damage a cable? Would be a lot more valuable IMHO if they bundled shorter and longer cables for different case/mobo combos.

Thanks, its always good to know that readers find our reviews helpful.

First question: Yes, both the EVGA 750W G3 and the Seasonic 650W Focus+ Gold PSUs proved to be excellent. Performance wise they are very close, both with very good voltage regulation, AC ripple suppression and efficiency (the 750W G3 had slightly better AC ripple suppression). The EVGA G3 also uses a slightly larger fan (128mm vs the Seasonic F+ 120mm) but they both are relatively quiet through mid-power range and both have FDB. And they are both backed by a 10-year warranty. So your final purchasing decision may come down to price - which one has the lower cost when you want to buy one (at this moment the Seasonic 750W F+ is about $20 less than the EVGA 750W G3).

Second question: I personally prefer a semi-modular PSU with a fixed 24-pin, 4+4 ATX CPU, and a pair of PCI-E cable/connectors. Its not like these are optional. Being fully modular adds more connection points (potential for added resistance/slight voltage drop) and a little bulk to the front of the PSU. I suspect manufacturers are going fully modular to lower production costs by eliminating the extra labor required to hand solder fixed leads.
