EVGA SuperNOVA NEX750G Gold Power Supply Review

Author: Lee Garbutt
Manufacturer: EVGA

Final Thoughts and Conclusions

Overall the new EVGA SuperNOVA NEX750G Gold power supply proved to be a bit of a disappointment. Since it bears the SuperNOVA name and is advertised as being a premium, enthusiast grade power supply we hoped it would have similar features to the flagship NEX1500 but in fact the NEX750G is built on an entirely different platform and does not support EVGA's SuperNOVA monitoring software. The NEX750G appears to be aimed at more mainstream, cost-conscious consumers. However performance and pricing are very competitive at this power point, which puts a lot of pressure on the NEX750G to excel.

The EVGA SuperNOVA NEX750G Gold power supply operates very efficiently and easily meets the 80 Plus Gold criteria for efficiency. It comes with a good assortment of all modular cables that include two pairs of 4+4 pin ATX/EPS 12V connectors and eight PCI-E connectors. Voltage regulation and AC ripple suppression were within specification and acceptable, but not as good as we would expect from a premium brand, enthusiast power supply. And while the cooling fan is advertised as being "quiet… for near-silent operation" it proved to be far from it.

The EVGA SuperNOVA NEX750G Gold power supply is currently available and selling for $139.99 USD ($129.99 after MIR, January 2013), which makes it a little on the expensive side given the stiff competition in this power range.

• 750W Continuous DC output at 50°C
• Very good efficiency (80Plus Gold certified)
• All modular cables
• Good build quality with all Japanese brand capacitors
• (8) PCI-E connectors for multiple graphic card support
• Universal AC input with Active PFC
• Backed by a 5-year warranty (upgradable to 10-years with registration)

• Doesn't support EVGA's SuperNOVA monitoring software
• Voltage regulation not up to par with competitive units in this class
• AC ripple on the +3.3V and +5VSB outputs higher than we would like to see
• Relatively noisy fan
• Higher price compared to strong competition

Shame that the regulation isn't a bit better. I love the modular design, but at the price there are some really nice Corsair models that are hard to compete with.

Indeed, why did they go with group regulated Aurum, when there are way better designs on the market. I guess they thought having Gold certificate immediately makes unit premium class. Hint: it doesn't.

Corsair makes the shittiest products since the comming of the so called "i" generation.
I've had 3 broken h100i's so far.. A customer returning an AX760i and a AX1200i.. they all had the same issues, link broke after a while, causing shortage or something like that matter. And making the unit completely useless..

So b**** please, don't tell people to go to corsair nowadays, it's a shame how you people deny quality over a "name".

I have this unit since the beginning and it never bricked on me.. the multi rails seem to be working super and I have none to minor fluctuation what so ever in my voltages and amps.

And I hear people say stuff, like yeah MULTI RAIL IS BAD.. Damn people this aren't the 2004's anymore.. This unit was build like a GOOD multi rail.. not a dual rail 10a + 25a hybrided together like OCZ used to do.

I got the 650 supernova for $70. From the small number of reviews I have read I think it is a bargain. $100 seems to be about the price now. I also got free shipping.:-) I have a Thermaltake toughpower 675 which has been great. The evga is going to replace a old thermaltake 430 with only 20 pin atx connector and 4 pin cpu..

It is amazing to me all the power supply aficionados. Well they think they are anyway. They are in fact followers not leaders and parrot what they hear from their masters....really, it gets old. Spend their life in their moms basement and spend someone elses money to get their rigs built.

This is a quality unit, it is not the best out there but it is light years from the worst. If you get it at a good price it will serve you well. The 650G runs an overclocked AMD FX based system complete with all the accessories, water cooling system etc.......also drive two 770s heavily overclocked with the voltage to board mod to run the voltages I want and the clocks as high as I can. That wasnt the original plan, it was planned for a single 770, but thats what it is and it runs it fine because it doesnt just say "650" on the side of it, it runs at just below that number continuously. Hold it in your hand and you will see and feel the quality. Then there is the 10 year warranty, you can see how scared that EVGA is the build quality of this PSU sucks. I get tired of the disinfo. To the above negative poster, put down your coolermaster or sparkle magic PSU and step up to a decent PSU. Thank me later.

cheers for the sensible comments, I was struggling to decide on a psu as I keep running into dumbass commentors, I narrowed it down to this precisely because they were bold enough to stick a 10 year warranty on it... 10 years for christs sake,, 10 yrs is a great statement on their belief in this psu.. what could you possibly whinge about with that....

and before it even gets said, when you register this unit with evga, it adds 5 more years on the warranty.

$89 with rebate at MicroCenter. That makes this a very good PSU for the price.
