I recently built myself a new computer and had to go through the dizzying research and shopping for the various parts. Picking out the power supply is never particularly fun, as you're basically buying a box with wires coming out of it. *yawn* Perhaps that is why the EVGA stood out, with its interesting handle on the back, not to mention its gold-rating and fair price. Also, unlike other (formerly) good names in power supplies, I didn't see any reviews for this one where owners reported popping, sparking, smoking, or catching fire, so that definitely narrowed things down! Seriously, I came across several such reviews for those other brands. No excuse for it.

The handle on the back is a mystery to some. As a feature for making it stand out from the slew of other power supply images you're confronted with while shopping, it's successful. But it has its practical purposes, too. I found, while installing it, that the shelf in my (mid-tower) ATX case was quite short, and this PSU is longer than my previous one, which - since it's pretty heavy - made it tip forward and in. Had it not been for the handle, it would have been very difficult to hold the PSU in place flush against the case while I installed it. Once installed, the handle doesn't have much other use. However, it looks cool, and I keep my digital camera's USB cable draped over it for when it's needed (I was always misplacing that thing before).

I can't speak for the longevity of this unit yet, but it seems sturdy with a nice big fan, a decedent textured finish, and the modular feature is fantastic! I don't need most of the extra included cables at this time, so I have ended up with an almost entirely clutter-free case. Lovely!

An extra star for presentation!

-CPU 8 pin actually reaches unlike most power supplies within this price range (I also dig how it has 2 8 pin cpu cables)
-fully Modular!
-Cables looks VERY clean
-80+ GOLD, WOW
-I have a few a evga products and the customer service is very good
-5 year warranty(most psu's dont have that)
-packaging was pretty fancy and organized, the unit came in its own fancy soft case....cables were folded.
-I also like the handle, pretty sturdy

Overall, I am VERY satisfied with this power supply, I've had other power supplies from within its price range
and it blows all of them away.

You get a lot of quality and features for the money.

I got this PSU about 2 weeks ago and so far I am extremely satisfied with it. Runs quietly and has no problem powering my system. Installation was very straight forward and clean due to it's being fully modular. Also EVGA is running a promotion at the moment where they upgrade your warranty from 5 years to 10 years when you register within 30 days of the purchase! Would absolutely recommend this to anyone needing a sturdy, efficient PSU.

This will not be a technical review of the product. I have not performed any instrumented testing regarding the actual power output of this power supply. It more than adequately powers my system and has never given me even the slightest hiccup.

Instead, I wanted to comment on the whole package of the product. I've bought many a power supply and maybe I've just not spent enough in the past, but opening this blew me away. The packaging is of the highest quality, the cabling is all very well done. It even came with a carrying bag (okay that is overboard).

It is essentially silent, my entire system is so this has yet to make me notice it, even when gaming.

This is completely modular. Most "modular" power supplies still have hard-wired ATX connections. You can argue that you can't run a computer without them so they might as well be hard-wired. I disagree. Case in point: the "modular" power supply that I had bought before was defective, but I didn't know until after I had completely assembled the system and routed all of the cabling neatly. If that power supply had been truly modular I could have pulled it out and replaced it without tearing all of the cabling out and I would still be using that model today. But after going through all of that again there was no way I wasn't putting in a truly modular PS.

I think the only negative comment I have, and a lot of people share this, is that the handle built into it is kind of silly and depending on your case configuration it can make it a little difficult to install where there is already a motherboard in place. That was the case with me, but it was not impossible. Once installed I admit it is kind of convenient for moving the system in certain circumstances but ultimately I would not have designed it with a handle.

In the end, you can probably get similar wattage for less money but this one checks all of the right boxes and I totally recommend it.

The manufacturer commented on the review below
I really wanted to like this power supply but, as has been noted by several other reviewers it has fan noise problems. This is particularly unforgiveable since one of its marketing points is "Quiet 2-ball Bearing Fan for near-silent operation". However, that is not remotely accurate. The first one we bought had a constant ticking noise as well as high-pitched whine. The whine wasn't too bad but the ticking was far too noticeable and made it louder than every other fan in the PC - even when the 2 CPU and 2 GPU fans were running at full throttle. Even worse is the PSU fan runs all the time, even when the system is idle - something that other Gold certified power supplies don't do since the high efficiency means they produce very little residual heat. But if you have a PSU (like this one) with a noisy fan when the rest of the system is idling and relatively quiet, it is very obvious and very irritating. Amazon sent a replacement and that one was even worse. Between that and the several other reviews about this problem, it's clear EVGA is using a poor quality fan in the NEX650G - perhaps even the entire SuperNOVA lineup. If they would address these fan issues they'd have a real winner. It's fully modular with good quality cables - although oddly only 1 of the 4 VGA cables has double plugs for higher end GPUs. I really think 2 of the 4 should be that type. I appreciate the fact that EVGA makes an effort to respond to problems posted here and on other retail sites - although it is unknown if they actually go the extra mile when communicating outside the public eye.Read more ›

I do apologize for any issues you are having, the operation of the fan on your power supply is not normal. I would recommend contacting your support team and requesting a RMA. All replacements are tested prior to shipment to ensure it this issue won't happen again. Please contact us at 888.881.3842 option 1 or by email amazon@evga.com.
