Here is the inside of the Gamemax RGB 850 I have thankfully replaced with a FAR better PSU. Just thought I 'd share for fun. Anyone here able to comment about just how bad the quality is by what you see? I tried to get a clear pic of the MOSFET's but couldn't.

 

 

dual Mag amp regulated. not too bad. still better than some group regulated psu

@sean8102Can you take a shot of that IC under input receptacle transient filter ? Looks like one of the 4-pin supervisor ICs judging by the space for 8-pin variant, and such, the unit probably therefore lacks any OCP as there are no DC-DC controllers with backup protections. Although we've tiered all Gamemax PSUs to tier E anyway so it's not like that would change anything.

How good is aerocool's cylon/cyclon power supply?
For which PC is it advisable to use a cylon/cyclon as a power source?

Hey, Take this with a grain of salt, but I had an MWE (v1) gold 80+ 750w cooler master psu, it started randomly shutting down when I was using my PC,  I checked it with a crap red bare bones Oscilloscopes (the stuff you find on for 22$). I set the ms (i think that's the measuring speed right?) to like 1ms or something I'd see spiked up to 12.5v which is pretty crap.

 

it also did cause me a ton of issues so I had to buy a new one (with the GF1 ARGB everything works perfect). but i'm only a hobbyist who hasn't made anything electronic in a bit.

 

Maybe you can add it to the potentially dangerous or low quality stuff?

can someone tell me which tier is this

Where does the Seasonic FOCUS GM-650 fall on the tier list??. Wondering about this one specifically https://www.newegg.com/seasonic-focus-650-gold-ssr-650fm-650w/p/N82E16817151202

 

i see several Seasonic GM listed in different parts of the tier list.

I was testing my psu, listed on tier d  but... I ran occt psu test, power consumption - 560W. What should I check to know if it's safe? Voltages are neccesarry, but what else? Home tests, without fake load. Besides that, my X299 mobo provides a lot of voltage and current sensors - anything worth checking there?

 

PS. There aren't any tests for this psu, so internals are a bit of mystery there... Maybe there's something more than producent claims.

A Thermaltake Smart SE 630W?  You don't check that "it's safe".  You just replace it. 

 

[siewcu]

TBH I don't have money for that at this moment. I've tried to check, while gaming it won't go past 350W and I think that it won't break now, but... I know that I need to replace that. I just wanted to try and check something, since there's no review about this psu. Just may be worth checking how bad it is.

Is this one any good?  Can't find it in the list.  It's either this Seasonic or an EVGA BR.

It's an old SKU, EoL and out of production for some time so i suspect that they're actually selling Focus GM but who knows. In any case, as long as there's a full warranty on it, 40CAD is definitely a steal.

Thanks.  I bought it.  I figure it has to be better than an EVGA BR.

"Seasonic PRIME based units experience shutdowns with RTX3080/3090 (and possibly RX6900 XT) GPUs, especially ones with unlocked power limit like FE and ASUS Strix. It is recommended, if going with such units, to overprovision wattage, 1kW for RTX3080 and 1.2kW for RTX3090"

 

Would a PRIME TX-1000 Titanium be sufficient for an Asus 3080Ti Strix? I'm kinda shocked that the wattage requirement for the PSU would be so high when the PC would never get close to using the full capacity (without crazy overclocking that is).

It's not clear, i would advice against buying Seasonic Prime PSUs if you plan to use RTX3080/3090 series GPUs or something high-end from next generations, which would likely be even more transient heavy. But it's not strictly power draw related issue in this case, more of design flaw in Seasonic protection circuit, because most other PSUs work fine, 750W for RTX3080, 850W for RTX3080Ti/3090.

I currently have a Corsair AXi 860 and was planning on getting either another Corsair unit or something from Seasonic as i have heard they are very good quality. The problem with Corsair now is that their PSU lineup seems way more complicated than it was when i did my last build 6 years ago. Its basically alphabet soup and i have no idea what does what. I bought Corsair last time around because they claimed the AXi had something like had 'digital power delivery' for 'smoothness' (where as now they use inline capacitors in their cables?) and power usage could be monitored via Corsair Link.  Also according to the OP Corsair units share the same problems as they are based on Seasonic ones.

 

Is the Asus ROG Thor any good by comparison? Their 20% off Cablemod cables deal sounds nice...

Hardly ... compared to EVGA for example, besides, you have a tier list right there, just look at models which are in tier A.

Only one lineup, AX, not AX-i or anything else. And it's discontinued anyway so you likely wouldn't be able to buy it anyway.

850W one is Focus, so apparently it doesn't have the same issues. 1200W one is Prime. THOR II all models except 1600W are Prime too, maybe they're fixed since they're fresh, maybe not, we don't know. In any case, with custom cables there shouldn't be an issue anyway because most of them lack the 12V v-sense wire, but i'd really rather buy Corsair HX for example.

I honestly don't even understand what the differences are between Corsairs high end PSU's now. is it just something to do with the 80+ rating?

 

You'll have to be gentle with me, i know very little in general about PSU's, reading through some reviews a lot of it is electrical gobbledegook to me. I'm not even sure what the difference is between single rail and multi rail! I probably researched it a long time ago and have since forgotten haha.

I see, so custom cables could solve the problem with any of the PSU's anyways since if they lack that wire the PSU isn't getting the 'signal' to trip the switch so to speak?

AX/AX-i series are supposed to be high-end 80+ Titanium. But while AX-i is indeed good albeit very expensive, AX ended up being worse than HX aside for efficiency because Seasonic couldn't or didn't want to customize their platform for Corsair demands, so it's just stock Prime TX. But it's now discontinued anyway so it doesn't matter.

HX/HX-i is 80+ Platinum. The only difference is iCUE / monitoring capability. And this series is not only practically the best of Corsair current offerings (disregarding 500$ AX1600i) but ones of the best PSUs overall.

RM/RM-x/RM-i are 80+ Gold fully-modular. RM has cheaper capacitors and no in-cable caps, both fine, especially if it's cheaper than RM-x. RM-i has iCUE.

TX-m are 80+ Gold semi-modular. Old, 2017' version was a bit loud, new 2021' version is fine.

CX/CX-m/CX-F series are the real mess tho. CX is better than CX-m electrically aside for modularity. And Corsair for some reason decided to make CX-F RGB which didn't sell, so they've discontinued it now. CX is apparently discontinued too.

CV is another weird series, sub 650W are group regulated, kinda refreshed / slightly improved version of VS, i.e not something you really should use with builds using a dedicated GPU. But 650/750W versions are better, kinda like CX-m but non-modular.

 

Then there are also different revisions of CX-m, TX-m, RM and RM-x but they're overall close to each other performance/quality wise so it doesn't really matter much.

 

Anyway, in most cases you look either for CV 650W, CX-F (while still available), TX-m, RM, RM-x or HX.

 

PS: Also, apparently there's also CS refresh coming, unless they rename it to something else.

Kinda, yes.

Hello, little confused about the list. How can a PSU be in the A tier, be golden, but have an note next to the name saying how it randomly shuts off if you try to use it with a graphics card? Why would that not be in the trash tier?

Looking for a PSU for a 12700K with some GC to be added in latter.

New (past 2018y) Seasonic Focus revisions do not exhibit this problem. Seasonic Prime Gold / Platinum units sub 850W are based on Focus, and such do not exhibit this problem either. Then, it is assumed that Seasonic Prime 1000W and higher do not exhibit this problem too, but i've seen some reports with 1kW units tripping too, so it's not really clear and i'll move 1kW units to low priority too.

 

In both cases, the footnote in normal priority subtier is there just to provide information about the issue that other versions of these models have.

 

If you need a PSU recommendation please create a dedicated thread.
