Nice, plain black PSU, good customer service 8/4/2020 5:06:35 PM

Pros: Grill is NOT plastic
No problems with fan size and sound
Dependable customer service with native English speakers
Sleek, all black - no mandatory gaudy colors or lights
Good selection and quantities of cords for my purposes
Cords aren't too short or stiff for a full case and 4 sata harddrives (though a little awkward at first)
Comes with velcro cord ties
PSU "tester" - so you don't have to use a paperclip anymore (not a big deal but convenient, I now use it to test PSUs from other brands, too :) )
Seems to have the proper safety features, so I don't have to worry about it bursting into flames when I'm not in the room...

Cons: Enamel scratches easily under metal alligator clip
One cord needed to be replaced (EVGA customer service handled this very well!)
Have to register right after receiving product for warranty coverage (30 days)
I'm not sure who manufactures this PSU for EVGA
Cords aren't labeled as well as they could be (I double checked the slot shapes to make sure everything was connecting right instead of relying solely on the labels)

Paid too much for it (Market is crazy right now, but needed it for work)

Overall Review: Was a bit hesitant to purchase this when one reviewer said that the grill over the fan was plastic. On receiving the product, I was relieved to find that it is NOT plastic! It has some sort of enameled, plastic-ish looking coating but if you tap it, it has the sound of cast metal. Also, if you like hooking your anti-static alligator clip to the grill, like I do, you will end up scratching off some of the black finish and see that it is very shinny underneath. I am a very picky person (artist) and was a bit perturbed at first that it scratched so easily, but I don't even notice it in the case (even though my case has a clear window).

Power cord issue and customer service:
My unit's motherboard cable had an issue: the connector was too long to seat properly into the motherboard socket (wouldn't 'click' into place) so I called up EVGA. To my surprise, the wait time was very short - maybe 20-30 minutes - and I was connected to what seemed like an American customer service agent. It really is great to have some one who natively speaks your language to help with tech support! I had to register the product online and call back but they sent a new cable to my home free of charge and it works perfectly! Very happy to deal with a company that has *real* customer service - just remember to register you product right after you get it to activate it's coverage (you only have 30 days to do it).

Fan sound: Was quieter than I expected, even running Blender in CPU render mode. That being said, I have a 7 fan rig, not including the CPU, GPU and this PSU's fans and the fan/s in my Cintiq monitor, so I doubt I would notice if it *was* a problem. Probably won't use the "Eco" mode - would have bought this without the feature (fan saving measure or just one more thing that can go wrong?).

Had some concerns over the company who manufactures this particular PSU (could not find who for sure, but it seems to be a company that makes PSUs in a wide range of qualities) but it runs better than my last (faulty) Antec PSU and EVGA has stood by the product so far - only time can really tell, but it's looking solid so far!

Works as expected 8/3/2020 6:47:26 AM

Pros: I'm not an electrical engineer so I cannot speak to any technical aspects of this as a power supply. Needed to quickly replace an OCZ 850. There was a VERY limited choice (probably due to stupid pandemic supply chain issues) so chose this based on name recognition and warranty. Fit the case, had all necessary cables (including, thankfully, an FDD adapter that I need for an expansion card), and solved my problem.

Cons: For my case (a mid-tower) the cables are barely long enough to route unobtrusively. I am a bit of a 'hid the cables' guy - for aesthetics, airflow, and reduce places to accumulate dust bunnies. The cables were long enough to reach components, but not long enough to tuck out of the way. Also the space between connectors on each cable was just a bit too short for me. ALSO price was a bit higher than I would have liked but that's capitalism for you - not much supply and "I need it NOW" = higher price. Could certainly have been worse!

Overall Review: Hey - I needed a power supply NOW, from someone I trusted and EVGA delivered. I've used their video cards before and now they've saved my but with a dependable power supply. As always Newegg ROCKS!!! And UPS came though with Next day delivery!

Works as expected 7/19/2020 8:19:36 AM

Pros: Was pretty easy to plug Eveything in!

Cons: None I did research before hand so I knew what I was purchasing.

Overall Review: This is my first fully modular power supply, I purchased it because I wanted something more reliable, and this was within my budget. I also needed the extra 4 pin for the cpu on my x470 motherboard for overclocking support.

Epic gaming calls for epic power supplies 7/3/2020 12:37:14 PM

Pros: Alot of customization

Cons: So...many....extra....wires

Overall Review: The power supply works, comes with it's own 24 pin tester so you dont have to do the paper clip method. The unit is very customizable to your needs but the downside to this is that in the box, there are so many extra wires for data plugs it's kinda ridiculous but that's just me and the way I got things set up on my own rig.

Lasts years? Try 3 months. 6/28/2020 7:42:10 PM

Pros: Great when it works

Cons: My assumption was that it would last a couple of years, instead it just died out of nowhere one afternoon.

Overall Review: Not worth the stress or rma process, go buy a corsair card
