Sorry for being such a noob but what do you mean with the actual digital ones? 

some have digital monitoring, some are actually digitally regulated

Okay... dude sorry to ask again, they'll soon be down with the next update you mean they are going to get worst (the digitally monitored, I assume?)

Thing is I got two defective aerocool project 7 psu's in a row and I don't want another one, so I'm looking for another PSU and this one is in stock where I got the aerocool and saw it was on the top tier, but now I'm not really sure if this is an actually top tier PSU...

 

Sorry again for my newbiness but I never ever got into PSU's so much as in the last days (when I actually cared about getting a good PSU, don't want to get anything fried on my pc)

both, but that's because we're tiering down all single rail psus for reasons

Though 1200W for a 300W PC?? (OK, more like 350W, maybe)

I'm buying it off of someone; I have no idea why he used a 1200W PSU for such a system.

Okay so I bought the Seasonic Focus+ Gold 650w (overkill I know, but it was as cheap as the 550w at that point), thinking it was a very good PSU (none of the reviews mentioned the issues that have surfaced afterwards). It has served me well (even when benching with a 8086k and a 1080ti), no shutdowns, no problems, reasonably quiet, etc. I'm considering selling it (as part of a different build) and getting a better PSU for my main rig. I'm probably not pushing more than 400w daily (possibly up to 500w while occationally doing some heavy OCs)

 

Nowadays, the Corsair SF600 Platinum, RM750x V2 and TX650m are all equivalent to 100$ where I live. There is also the Seasonic Prime Platinum 550 (140$) and Prime Gold 550 (120$). Would any of these be a better and safer PSU, and is it really worth the upgrade?

It comes with a bracket for normal ATX mounting and I wouldn't really mind a smaller PSU in my already cramped Meshify C.

The main issue is with cable length. Shorter cables with the SFX power supplies. 30cm motherboard and 40cm CPU power cables for the Corsair SF600, might not reach where they need to go in a larger case.
If you want a 80+ plat Corsair power supply just go with the HX750. Should be comparable in price to the SF600.

I didn't know this, thank you! That pretty much rules that one out...

Unfortunately it's actually a lot more expensive (165$). But I guess that's the price I have to pay for an actual upgrade form what I already have?

What tier is this PSU: https://ca.pcpartpicker.com/product/ss6BD3/thermaltake-power-supply-pstpd1200mpcgus1

If you need to ask what tier a 1200w PSU is you shouldn't be considering it even in the unlikely situation you actually need 1000+ watts

Single rail units exceeding 650W will not be placed above Tier A.

 

Why? Can someone explain... Don't really know how PSU works

If a component in your computer short-circuits in a particular way, it starts demanding infinite power from the PSU. If you have a single-rail 1000W, it will send all that power to the failed component, breaking it and/or burning the cables. If you have a multi-rail 1000W, it will shut down when it exceeds the power limit on the rail assigned to the affected cable (for example at 480W), which isn't enough to burn the cable.

Well so much for the tier list, won't be recommending it anymore after the latest change.

 

That's never again.

 

Too much bad information added.

 

Can't believe they bought into that stupid BS.

 

It went for being actually really good to almost completely totally useless now. ?

 

Needs to be changed back or completely removed from the forum.

Only when the 12V rail shorts.

And even then, you have UVP and SCP to protect you.

Heck, maybe even OTP could help.

 

I'm no electrical engineer, but I'd expect the single shorted wire to produce so much heat it's resistance would rise quickly, and the UVP would trigger before the max wattage.

Sometimes yes, sometimes not.

Here an eye opening review with a Unit where they messed up OPP and nothing can stop it...

https://www.hardwareluxx.de/index.php/artikel/hardware/netzteile/29916-enermax-triathlor-eco-650w-und-lepa-maxbron-700w-im-test.html?start=3

ITS GERMAN!

 

Because no UVP is there...

29 minutes ago, Rexper said:

UVP on 12V is missing on many 8pin Chips.

You might want to look up HY-510N for example.

WT7510 doesn't have UVP on 12V as well.

And probably some other units as well.

 

And SCP is just Marketing Propaganda as that is a product of either OCP, UVP or other stuff.

 

29 minutes ago, Rexper said:

...wich isn't implemented in some units at all.

While other units have two independent OTP Implementations...

So can't be that expensive...

29 minutes ago, Rexper said:

And what happens if you have a resistance in a cable? It reduces the current that allows to flow through...


So without measuring the voltage drop on the other end, you don't know the Resistance., And that there might be something wrong there...

But if you measure the Voltage drop on that cable, you basically have OCP anyway. So why not do it that way in the first place??

 


PS: Back in the day, the Multi Rail was done with LM393 and 339, depending on the Rails. My 4 Rail Enhancy thing with 650W and 80mm fan (and a total garbage fan controller) has a WT7510 and two (SMD) 339 right next to it.

Another HEC 2 Rail also had the WT7510 and an LM393 (or was it the 339?? I don't remember) right next to it for the Rails....


So you can either use a WT7518, wich seems to be the preferred way, or design it with a random jellybean component from whatever you feel like.

Yeah that's why there is protection testing. Well it's good if its German I'm trying to learn either German or French anyway gotta choose in between.

 

Isn't there a virtual multi rail which basically a single rail or is it a different thing Hmmmmm.

IDK what UVP is or just forgot because I don't really care about it, except MOV ATM.

A couple PSUs that (seem) modern that are missing from the list:

 

Rosewill  LEPTON, RBR1000, and HERCULES

 

Lepton looks like it may be up there in Tier A with Tachyon and Photon.

 

Thoughts?  Comments?  Add it to the list?

That's not true. Take this Kolink for example: https://www.tweakpc.de/hardware/tests/netzteile/kolink_sfx-350/s06.php

OCP on the 3.3V rail is missing, it drew up to 35A (it's a 350w power supply).

UVP is missing on the 3.3V rail, you see it drop to 0.2V...

However SCP was atleast half functioning.

What you're telling me is I can't make a blanket answer regarding how beneficial multirail is, because it depends on the protections and the power supply as a whole.

So why do you make a blanket criteria in the tier list that all high watt single rail are below Tier A?!

And what is SCP? How was it implemented? What Protection does latch?

No, it depends on the Wattage.


On a 500W you can probably omit it.

On a 1500W you must not.

 

Multi Rail = Breakers in your Box.

You usually don't need them either. You have them so that the cables in the wall don't catch fire.

And in some weird systems (*caugh* UK *caugh*) you have 32A lines/Breakers and need another one in the component.

9 minutes ago, Rexper said:

What is less dangerous?

50A OCP or 150A OCP?

Especially when a shitty connection is enough to prevent "SCP" Detection...

 

As someone with some kind of electronics background that's pretty obvious to me. But also high current with low Voltage are even more dangerous than the same current with higher voltages because the Resistance of the Cable overall is far more with 12V than in 230VAC as we are talking about some milliohm that are needed for a short to be detected...

Due to your list, in Viet Nam the FSP Hydro PTM 650W Tier A+(cost ~101USD) and the Seasonic Focus + Gold Tier A (cost ~140USD). How is this possible or the seller set the wrong price tag? Sorry for my bad english.

Its not a wrong price.

But its possible tue to different import cost, importeurs and thus different margins for them.

 

That's why looking at the price is important.

 

PS: the FSP is the better one anyway!
