EVGA Power Supply
TechPowerUp (2014/06/01)

This platform is a real performer... its voltage regulation is tight, which results in stable DC rails, and its excellent ripple suppression is cause for very clean voltage outputs. It also features a fully modular design, a feature most users look for nowadays, and packs a silent overall operation because of its quiet fan and optional semi-passive operation...

EVGA Power Supply
HiTechLegion (2014/04/01)

The 850 G2 delivered some of the best performance we have seen to date...

EVGA Power Supply
JonnyGURU (2014/04/01)

Buy one. Do I really need to say anything else at this point? Once again, EVGA has something awesome here the competition can't seem to touch price wise.

EVGA Power Supply
PC Perspective (2014/04/01)

Both the SuperNOVA 850 G2 and 750 G2 power supplies exhibited outstanding voltage regulation with low AC ripple, even at full load.

1 out of 5 eggsDestroyed Both HDD's

Pros: Modular, but that's all I really know since I am now too afraid to use it.

Cons: As soon as I turned on my PC I heard a noise I had never heard from my PC before, like a buzz. I passed this off since I normally don't have my head as close to the PC as I did at that moment. I hop into my chair and see that my PC is going straight to BIOS. Re-Boot. BIOS.

I begin to troubleshoot and begin to realize that neither HDD is spinning up. No noise, nothing. Thinking that maybe it was the PSU, I swapped the old PSU back in. Still nothing. I took the drive into a shop to see if maybe it was just my PC causing the trouble. Still not spinning up.

My HDD's were working perfectly fine just before the install and none of the work done even went close to the drives. There is a silver lining. I am hoping that the PCB is the problem, and that the stars are right where a new PCB may work.

This has really put a damper on things since some of the files lost have been in my possession for almost 10 years. In the future I will most definitely be backing up my files to avoid this. And I do hope that I am the only one to get a faulty device.

5 out of 5 eggsGreat PSU with awesome attention to details.

Pros: This is the first modular PSU that I bought ever for my system. It is a lot better than traditional styles PSU in terms of cable routing. The tech review sites give this PSU a pretty good score. It is built by SuperFlowerFactory, which is a known for quality PSU manufacturing. The PSU comes wrapped up in the cloth bag secured within foams. The supplied cables are really sturdy and good looking. Overall it is a very good 850watt PSU. Another thing I really like is the ECO switch which allows even better power efficiency.

Cons: Now to the actual cons. First, the SATA power cables are not well designed. It is kinda difficult to attach multiple SATA devices due to weird angles of the plug. Second, the PSU does not offer RPM monitor for the PSU fan. My old Antec 550watt PSU has that and it was a really good addition.

Other Thoughts: There are two versions of the SuperNOVA 850watt. This one is G2, which is made by SuperFlowerFactory The newer version is GS, which is made by Seasonic. According to reviews it seems that G2 is better than GS. I would highly recommend this PSU.

Pros: Comes in an incredibly sleek box, does what it advertises.

Cons: haven't seen any yet

5 out of 5 eggsGreat

Pros: I have been using this power supply for a little bit with a system that uses about 500 watts and the fan hasn't even turned on yet. Comes with plenty of sata cables and has a quiet fan when not on eco mode. Looks great. It comes with a brick to plug into your motherboard connector so you don't have to plug it into the motherboard for it to provide power.

Cons: I didn't get it sooner

4 out of 5 eggsAll I need, and more

Pros: Fully modular, I like this over my previous partially modular. The weight and feel of the actual power supply gives the impression of very high quality. The cables coming in a wide variety and number of connectors is convenient and they (the cable part) are solid and wrapped in a fairly strong tube.

Cons: Almost everything I have experienced with this power supply has been perfect, I had to take off an Egg however for 1 reason.

The actual connectors for the modular cables are VERY flimsy and cheap. I had the quad-SATA power cable setup with 3 drives in a vertical sequence and from just the tension between the drive above and below it, the middle power connector had its back tear out so that it is exposed and cannot maintain a connection.

Other Thoughts: I received my rebate in about 6 weeks, it was a nice surprise as I didn't really expect it.

The cable management in my case is the best it has ever been.

The pouch for the cables is convenient and I use it for other components as well.

1 out of 5 eggswell....we had 3 good years

Pros: It lasted 3 years running an Asrock x58 extreme with I7 920, and old GT 250 video card , two small hard drives,and 6 gb memory. Not much power needed here folks, move right along...

Cons: Last week it just went POP and took the AsRock and CPU with it. So my original $89.00 on sale will now cost me around $500.00 in damaged goods. Lucky the drives didn't go too - I still have my data. Could have been 3 eggs except for the collateral damage.

Other Thoughts: I might RMA but not sure I want it back - I don't trust it after a burned board. Time to upgrade to an X97 or X99 with an EVGA 850 G2 made by Leadex. I'll stay away from the newer EVGA 850 GS made by (you guessed it) Seasonic.

5 out of 5 eggs100% satisfied with this PSU

Pros: No more coil whine!
No more buzzing noise!
10 year warranty!
Most important, very stable and very quiet!

Cons: None

Other Thoughts: I'm very pleased with this PSU purchase. I ordered this PSU on Sunday, and it arrived on Tuesday. Previously, I returned another brand of PSU; that wasn't as quiet as Evga SuperNova G2. Newegg has the best customer service and fast shipping! I love shopping at Newegg!

Cons: None.
