Those are all semantics, High Power is the retail brand of either Sirfa or Sirtec, i'm not sure which exactly since they've split up in 2008,

These comments are distinctly self exclusionary, so the rest is just, well, I guess it just doesn't really matter after that. Especially since that was 13 years ago, so, clearly, ALL of the reviews AND models I was referring to, were explicitly SINCE then. Kind of makes that idea irrelevant, like a lot of other things I read here sometimes.

He mentioned that Aresgame is a subbrand of a large oem, but didn't mention what OEM. Any clue?

If I had to take a wild guess I would say Andyson

OEM isn't Andyson. Steve says that the OEM has been around for 15 years now. Andyson was founded in 1997, making it 24 years old.
What could fit the bill, is High Power, since that was founded in 2008, making it's lifespan 13 years. Or it could be some other, less known OEM.

They even have their own YouTube channel: https://www.youtube.com/channel/UCQhgVqTnIRuxem-hnaW1u6g/videos

And in there, they have vids of their factory. Maybe someone recognizes the factory.

Edit: After extensive Google-Fu, i think the OEM / parent company of AresGames is Shenzhenshi Jiumeng Electronics Technology Co.,ltd.
My proof, trademark registration application: https://uspto.report/TM/88619100

And it fits the bill as well, founded in 2006, making it 15 years old.

I think some people forget the dark days before we had 80+. I know I've been one to just suggest 80+ gold and been called out on that. Something he missed in the video was that in the dark days companies would claim their PSU can output 500W, but it was really a 300W model. 80+ has eliminated most of that problem. 80+ does require testing at 100% load. So it either doesn't have the 80+ sticker, or you wouldn't find it in the database, assuming you bothered to check. Trust me, fake PSU ratings were a problem in the long ago.

Another thing he didn't mention was how 80+ tests, at 25C. It's possible for a unit to be fine there, but fail at the temps found in a case. In addition, as he pointed out, 80+ is just efficency. poor caps that explode at 40C won't be found out by 80+ testing. It's a start, but lying does still happen. And there are more things to worry about than 80+. BUT, at the end of the day it is a useful thing to look for. I have yet to see a great PSU that doesn't have an 80+ sticker. You do need to do more research yes. But at least you know that 500W PSU has a chance to actually output 500W if it says 80+ bronze or gold.
 
80+ is quite old standard and for now, is more of a guideline than actual rating to be considered. Especially since it can be faked easily.

Though, Cybernetics is making waves and it would be interesting to see their certifications becoming standard (must have) for PSUs.

Also vampire power and PF, still, it's not a quality certification.

Yep, as a separate program but still, it's not quality either.

I think you'd never get any of these certifications to test quality. Quality requires more extensive testing and can be subjective. If a PSU gets a bad rating, because its a worldwide certification (and not just an article) the manufacturer could consider it to be a major issue and then file a lawsuit to change it. Its just opening the rating company to litigation,
 
Maybe. But if company A submits sample for review its not an issue. Could be an issue if certification company randomly buys units, but if you are submitting product for review you sort of have to agree with the outcome.

It's not "making waves" because it's been around for a long time now. What it IS, is the only REAL standard, at all. So it's good that we all see that.

Then again, just my opinion. And I think we have already ALL agreed on what that is worth.
 
Sure. The only thing required is the base 3 protections according to atx standards, plus whatever EU requires. There's no saying you have to put uvp or any of the other protections in place. CWT is just the manufacturer, not the purchaser. Quite easy to just ask they skip that build step, which cuts costs, manufacturing time, supplies use that's already limited etc.
 
Especially considering it's Deepcool. Yes, they have had a FEW decent products over the years but they have REALLY skimped on quality and features for much of their product line at times as well. But, it could also just as easily be that it was overlooked when the webpage was put up. Until the last couple of years, even the more prominent PSU manufacturers often didn't list the full feature set because they assumed most didn't know or care, and marketing was king. Still is for the most part, but there are far more at least semi-educated enthusiast consumers out there than there used to be and a lot of them have begun being more transparent about such things. But it could still certainly happen.

I was looking at the deepcool PM-D line. It just looks like another cwt GPS, but the website doesn't list UVP. That's a pretty big flaw in my book. Think it's actually missing or just a mis-step on their listing? Would CWT even deliver something without UVP in the first place.
Click to expand...
It's not CWT GPS.
Judging by the shot they use Sitronix 8-pin supervisor, i don't see what model but it likely has UVP on all rails unless they've saved a couple cents on ST9S313B.
It's common for marketing folks to not list some protections which are still there so i wouldn't be surprised if that's the case. Although, i wouldn't trust Deepcool after their 'upgrade' of DQ-M into DQ-M-V2L, so until we'd have a teardown confirming that the supervisor has UVP it should be assumed that it isn't there.
@DeepCool_Phoenix I'll repeat my question. Can we expect some reviews on it ? Even if that was supposed to be a SI model, it is now on the shelves so people would want to know what they're buying. Even just sharing a BOM and ATE testing reports for it would help.

Its really a shame that Amazon promotes products like this. Granted, Amazon wouldn't have known there was an issue without proper testing.

I have doubts about their claims that some of the units meet 80+ gold. I can't say for sure if they did or did not, but using double forward and having underwhelming component quality elsewhere, meeting 80+ gold would have been unlikely.

And the review by Aris is also out: https://www.tomshardware.com/review...r-supply-review-less-efficient-than-wed-hoped
 
Even though this unit would never be able to be considered good, a fair bit of the cons of that unit would be somewhat able to be overlooked if the price was right and the unit was marketed correctly.

Change a part or 2 to make it comfortably bronze, and sell it for a price representative of its performance and it would be more acceptable.

But as it sits, that unit just needs to go away and Aresgame needs to be more transparent

It looks to be cash grab and/or fame collecting for the brand, by over-marketing the PSU, which most likely also includes positive review buying in Amazon.
Also, i doubt that the brand would be around long enough, for anyone to test if PSUs do actually last 10 years and if not, to RMA it.

Enough said.

And on another note, I want ALL of you guys, even some of you whom I've likely slighted or hard disagreements with in the past, to know that I definitely appreciate your contributions here AND also in the ("bastards, I hate 'em, but I also really like 'em" thread. Sorry guys, it was compulsory.) other various PSU threads, because every one of you has contributed to us ALL knowing more about power supplies, and I think that is the bottom line reason why we all congregate around these kinds of threads. So thanks to all of you who do this. You are appreciated, by me at least, whether you've ever had disagreements with me or not. I'm working on being more agreeable too, so, feel free to touch base if you have ideas that might benefit the community.

Tx

Well, with a title like that, now I need to know where this "bastards, I hate 'em, but I also really like 'em" thread is! 🤔😆

And, also, thanks for your efforts in starting the thread, and those who've added to it.

This has literally taken me away from that stage where I thought "The power supply? That thing comes with the case, right?"
