I didn't see any mention of the Corsair CS-M on the front page. Its not too shabby given its age. Granted it has been EOL for awhile, but its still a unit someone might come across so I think some mention of it in whatever category would ne nice.
The Corsair CS450M PSU Review (anandtech.com)
Corsair CS Series Modular 650 W Review - Value & Conclusion | TechPowerUp

Currently I have a CS450M I got for $15 (plus shipping) off of eBay chugging away in my i5 760 + R9 280x machine an it takes it no problems.

Recently Jon said they are making a resurrection of the CS-M and it is going to be 80+ Gold, double forward (presumably with DC-DC), CWT based, and semi modular. Somewhat like a better CX-M

I just got a xpg pylon 450w for my dad's old pc. The primary cap is a nippon chemi-con KMR(instead of KMW), but the secondary caps are all CapXon, unlike the 750w version that was reviewed, which had all Elite secondary caps. (I was just shining a light through the grating, don't plan to take it apart)

Bit of a letdown, I'll still keep it as load in this system will never exceed 200w(HP prebuilt).

 

[NightHawkRMX]

Yea, not a fan of CapXon after having to recap a CX600 with failed CapXon caps.

But it should be fine.

As for me, this is the best PSU in terms of price-quality ratio.

I do not see it listed here. Fake 80+?

Also I would never reccomend Chieftec. I can almost guarantee something better is available, even in some countries with poor selection of parts.

2 year warranty is kind of a joke to be honest. And its missing a bunch of protections.

2 year warranty, missing protections, unknown OEM.

This is the best PSU if you would like to light your house on fire.

You don't look at Cybenetics for 80+ certification, you look here:

...and it's there, so it's definitely not fake.

By the looks of it, assuming that the Russian site's trustworthy, it's a standard CWT gold platform, which is decent. The internals are decent except the sleeve bearing fans. But two years warranty? Seriously? Maybe it's not going to burn your house down but I'd rather have a grey CX or CM MWE V2.

 

[NightHawkRMX]

Lack of protections I find unacceptable

 

[maxamillionfeettall]

Looks like CWT GPS platform, like the thermaltake GX1 and montech gamma II, among others.

 

[NightHawkRMX]

I have been curious about those Montech PSUs, just like I was curious about the Segotep.

I don't particularly like the Montech Gamma II since for a non modular 550w version its like $65. Not a bad price, but you can get decent name brand units for similar price, like a CX550.
Alternatively, the Segotep GP is $15 cheaper in 600w version.

If it is really CWT GPS as @maxamillionfeettall suggested then it shouldn't have missing protections, it is just Chieftec being stupid. I am not good with CWT platforms so can't really say for sure. Montech seems to be that brand that rebrands CWT PSUs (like Chieftec).

 

[NightHawkRMX]

The Sitronix ST9S313-DAG microcontroller , which is also found in the most budget devices , provides a basic list of protections:

overvoltage protection (OVP);
short circuit protection (SCP);
over power protection (OPP).
It usually allows for undervoltage protection (UVP) as well, but in this case there was no support information

Not sure what's up.

 

[4745454b]

Considering the hat and cap selection, that's why it has a 2yr warranty. Hard pass for me. It will probably serve you well if you keep it cool enough. But considering those caps I'd avoid it.

 

[refillable]

Not sure what's up.

Actually, I might be mistaken. The Enermax Revolution XTII don't have OTP and OCP as well. I guess it's where the CWT GPS tops at.

 

[NightHawkRMX]

If it truely has no ocp and no uvp, that's bad. If you overload one rail it probably will 'splode.

Exactly. 'Nuff said.

That PSU isn't the "best available" in ANY region, when it comes to budget offerings. Not any region that I've seen anyhow. I know Chieftec is somewhat popular in many EU countries, and a few others, and while they do have a few that aren't likely to cause a dumpster fire, they have many that are, and the ones they have that aren't are generally more expensive than other options with better pricing from other companies.

You could certainly do worse, but you could also absolutely find something better at or near the same price for practically ANY region, unless you are somebody who is 100% limited to buying from local shops that have a very limited selection.

Well Aris said the supervisor IC supports UVP and the Enermax Revolution XT II has it, it is just that Chieftec isn't promising that. But still, no OCP and OTP PSUs in these days should be reserved for PSUs under $50.

I have a few pictures I will upload later that further confirm "ORION" as a brand that should be avoided.

Basically, I have a "585w" Orion PSU. Label claims to have dual 12v rails with 19 and 20 amps on them.

Lies.

I tore it apart and it is clearly marked as an HEC HEC-300AR-TF on the PCB. No it is not a 585w PSU. No it does not have 2 12v rails.

You're surprised? Heh.

 

[moccor]

Does anyone think it would be a bad idea to run two GPU (mining) off a EVGA Super Nova 650 G5? It has only 3x PCIE 8pin connectors but I believe I have a 4pin to 8pin EVGA adapter. It would only be running the 2 GPU and maybe 2x riser cards, so that's like 440watts total

 

[4745454b]

If you have to use adapters, no. You don't say which gpus so can't say for sure. But i would never use an adapter.

 

[g-unit1111]

So I'm looking for a PSU to power my new 3080. I am looking at the Seasonic Focus PX-850 but am also open to the Corsair RMX850 and the EVGA GQ 850W .I was also looking at the NZXT E850 which is a Seasonic PSU.

Right now I'm leaning more towards the Seasonic over everything else but am open to suggestions.
