A Detailed Look
The EVGA Supernova 550W G3 power supply enclosure is painted matte black and measures 150mm (5.9”) long. The same compact chassis is used for all G3 Series power supplies, up to and including the 1000W model. The back panel includes an AC receptacle, main power On-Off switch, and an ECO Thermal Control fan mode switch (On enables fan-less operation).
The 550 G3 power supply incorporates EVGA’s ECO Intelligent Thermal Control System for fan speed control. This allows the end user to select silent, fan-less operation for low to mid power applications if desired.
With the ECO Intelligent Thermal Control System turned ON, the power supply cooling fan does not start spinning until the internal component temperatures reach a pre-programmed setting. The fan then starts out at low speed and gradually ramps up based on load and temperature (see graph above).
The power supply uses a 128mm, seven blade fan on the bottom for cooling. The EVGA labelled fan (H1282412L) is rated for 0.18A at 12 VDC and is controlled by the ECO Thermal Control System. It features a hydraulic dynamic bearing for long life and quiet operation.
The front panel on the 550W G3 incorporates eight modular cable connectors.
All of the modular cables are sleeved with a black nylon mesh covering.
Under the Hood
Here are a few pictures showing the layout and components inside the EVGA Supernova 550W G3 power supply. Just like the original G2 series, the G3 Series is based on Superflower’s Leadex platform.
The G3 series features a modern LLC resonant circuit design with DC-to-DC converters for increased efficiency. The layout of components is clean while the soldering appears to be very good. All of the capacitors used inside the G3 PSU are high-quality Japanese made (primarily Nippon Chemi-con) electrolytic and solid polymer caps. The 550W G3 uses a single primary capacitor rated for 390uF, 400V and 105°C.
Thank for the great power
Thank for the great power supply review Lee! I am using the G2 650w version in my rig right now, based on your review of it, and love it. So this new version just has different fan, and perhaps slightly better performance than the G2?
Mostly it’s just a smaller
Mostly it’s just a smaller chassis for the unit. No real gains otherwise.
Jonnyguru reviewed it 200
Jonnyguru reviewed it 200 years ago. And by review, I mean a proper one. Pcper late to the party with laughable tests, as usual. Stick with your nvidia sponsored Geforce “reviews”, thanks.

You obviously have no clue as to what testing methods that Lee uses, so I took the time to find the video where they go over his testing methods and setup:

go to about 50 min into the video where they go over Lee’s setup and methods.
Now as to the rest of your statement, I get it, we all know that the way PCPer presents content about AMD, Intel, and Nvidia tends to be biased one way or another, and I do agree with that part of it. But the claims you make about their PSU testing is false.
EVGA are well known for their
EVGA are well known for their PSU quality so i wasn’t expecting anything less from this G3 series . I personally own an 1000W P2 and it has been flawless since 2 years now.
The only thing that i would like to change are cables. In my opinion flat cables should be standard .
I have the 1500watt monster
I have the 1500watt monster they discontinued awhile ago bought when the 4960x dropped for my monster rig back in those days been absolutely flawless.
The plug is like a oven plug massive but can tell high Quality all around its got a nice 10 year warranty which is actually almost half way up.
Good to see they upgrading there PSU lines I’ll have to buy another 1500+ Beast when pcie 4 comes out and nvdimms gota make sure all my hardware has a plethora of room to breathe.
By all means post the specs
By all means post the specs of this hardware so we can see you love to buy way more PSU than required.

Asus Rive Be 4
intel 4960x oced 4.8 ghz
64 gb ddr 3 2400 mhz Corsair Dominator Platinum

1 Intel 910 800gb pcie ssd
2 Asus Titan X (Maxwell)
i also have it linked to my cyber power backup system software says its only drawing 410-440 watts which has to be a bug, but i got it so the rig gets clean power with pure sinewave 2.
suprisingly only thing i need to change out is the ssds as there not enough for my os drives, ill replace with pcie adapter and a 1Tb 960 pro for nvme.

Last 2 EVGA PSUs I got were both DOA. Won’t buy them again. use Corsair for my builds now.
heard the horror storys of
heard the horror storys of the corsair psu’s causing shortages, must been there cheapo 650 watt mx line, heard there was a paticular series to avoid if your building HEDT systems, DOAS happen iv had 5 at one point, but Evga psu last like Tanks, this one hasnt skipped a beat in nearlt 4 years of harsh service, love this thing, cant wait till nvdimm/pcie 4 then ill upgrade, turn this beast to a server.

Is it properly wired for the 6 pin pcie (GPU)
That dam connector pcie configuration has one pin not connected or optional from maker . Most power supply maker use a 6+2 config and in this situation you got to make sure it’s doing the proper thing other wise it will rise the volt amp etc value too high and you GPU will have a tendency to be hot and be very often in protection mode . Often the optional used by maker are not properly maintained so it tend to go ride the pcie firmware instead of simplifying thing .If you can’t stay away from the GPU with 6 pin connector.most power supply vendor don’t bother and this is a huge issue causing trouble
Nice review. So, even 550W G3
Nice review. So, even 550W G3 can power crossfire/sli configuration. That is nice. But, I’ll rather hook up the second pcie to a nice sound card

We live in a world where companies strike it rich on the gullibility of American market segment. They are all made in China, with just big words to lure you all fools in.
Unbranded PSU is the way to go! 🙂
I OC my 3.5ghz to 4.6ghz 🙂 the magic of some tender love, a mini-fridge where i keep my PC for cooling, and the unbranded PSU. Sometimes i plug my powercable directly into the wall and i get 5.5ghz OC 🙂
