This power supply was $44.99 with free shipping refurbished the other day. Surprisingly, I had enough self control not to buy it, but a friend of mine who was in the market for a decent standard length PSU did buy it and took some photos.

From what EVGA says, it looked promising.
7 year warranty
Full Japanese capacitors
50c rated
Full set of protections including otp
Fdb fan

Any clue who the OEM is?

Very odd layout to me, definitely not a platform I am familiar with. DC-DC boards are pretty prominent at least, but overall odd layout.

No photo of the underside of the PCB, but with the jumpers I see, it looks like a single layer PCB.

If that's not the truth. Things were good back when they made sense, NEX-g1-g2-b2 etc, now there's G(pick an alphabet letter) and no idea which is good, which is better, which is junk. Need an excel spreadsheet to keep track of even half the models.

I'd not be surprised to know that somewhere in Evga Corp offices there's an alphabet dartboard, and the janitor throws a dart over his shoulder blindfolded whenever Evga needs a new squ letter.

I think people would be willing to sort all through that and make reviews and whatnot IF THEY DIDN'T <Mod Edit> CUT OFF THE REVIEWERS THAT REVIEW IT PROPERLY.

I don't have any issues with running EVGA bstock psus in my personal system(s).

I thought I had issues of with a cheap bstock PSU once, but didn't send it back because of shipping cost. Pretty sure that psu actually is fine, considering I pulled it out of my drawer earlier today and it fired up a system perfectly.

So I have never actually had any issues with a bstock PSU.

My i7 990x+gtx590 system is currently running on a $65 bstock GQ850w. Works absolutely perfectly.

Then again, my main system is using a Corsair HX750i that I stole from an older computer I bought off of eBay and I don't have a problem running that in my main system. To me a used or bstock PSU is fine as long as it hasn't been abused.

I could see a 5XX - 7XX running on it. I have an older PC that I built that runs my old 660 on a Corsair CX600 and it works fine.

That's not going to stop a reviewer in the slightest. If you look at HardwareUnboxed, they buy locally most of what they review, they receive very little from the big corps.

Most of the issue with the reviewers is they have moved on, retired, got better paying jobs, gotten out of that demand and it's such a specialized field that there weren't that many to start with.

Jon Gerrow's, Oklahoma Wolfe's, Gabriel Torres's just don't grow on trees and Aris can only do so much. Steve from GN even showed an interest, but realized in a hurry that he's missing an education and the time required and equipment required to do the job right is out of reach. It's a huge investment both financially and personally to get it done right.

And if you don't, there's a reviewer over in China somewhere who tried, and gets blasted with every review.

Like you said, specialized field with not a lot of people. Aris is one person, and other reviewers can't keep up with all these newer EVGA power supplies, EVGA basically blacklisting him from receiving products for review is a major detriment in the process to evaluating the quality of these newer EVGA power supplies.

Thought id log into this old account and make a post for the first time in years on here. Anyways, these are my photos that i gave permission for nighthawkrmx to upload, i was overall pretty happy with the build quality, didnt see anything wrong with it, soldering quality etc is fairly standard for HEC. I wanted a cheap decent unit for a standard size atx psu instead of the extended length one ive used for years. I dont really have issues with bstock, most stuff is returned for stupid reasons unrelated to actual issues (like fanless mode at low loads).

yeah i think 45 for a 650W unit that is between a CXF and an RM in quality is a very good deal. It can handle some nice newer cards based on this info, like a 3070, 6700XT, etc

If only EVGA didn't blacklist every reviewer who has the audacity to say that a W1 is, in fact, a terrible power supply, maybe we'd feel comfortable recommending them, because then we would know about protections. Until then, it's hard to trust EVGA's claims at face value when they have claimed OCP on a unit that exploded from having too much power drawn. It doesn't matter how good a unit is if people don't know that it won't explode when you hook up a high end GPU.
Ah well. Until then, we will just have to keep relying on CXes and MWE Bronze V2s at this price segment.

Well, speaking of GT specifically, Jon seems to be pretty confident that it's just a stock HEC TPK and we have reviews on it, because it's Cougar GX-F. But with pretty much everything else from EVGA after G3 ? No luck.
