Good Bronze 750w PSU

[wNotyarD]

newsflash! You just contradicted your former statement with your latter. If you confuse security with safety (or in this case simply overhead because the user in this situation fails to understand their current and/or future power needs) you should not be giving advice. Thank you, end of discussion

Ok... let me give you the definition of safety by the Merriam-Webster:

The condition of being safe from undergoing or causing hurt, injury, or loss.

And also, by the Merriam-Webster, the definition of security:

The quality or state of being secure: such as

• freedom from danger : SAFETY

So in my interpretation, preventing loss of data falls well within the definition of data safety.
Unless you're using British English, which may not interpret the word safety in the same way.

Everything else, I agree with you. Be it the Corsair RM/RMe/RMx or the Seasonic Focus, they're all good units and provided the user doesn't ever exceed their rated power for long (as they all have been tested to be able to exceed their rating if pushed to in brute loads, but spikes are random by nature) there is no wrong choice. With his current RX6650, 650W will suffice. I just would be wary of spikes tripping it with anything above a RX7800XT from the current crop of graphics cards if paired with any 105W+ CPU.

Ok... let me give you the definition of safety by the Merriam-Webster:

fantastic, take it up with seasonic or any other OEM that your interpretation of adding more power to a PSU makes it safer. Let me know how it goes otherwise you just pivoting in a pathetic attempt to cover up a wrong statement. And as I said before, discussion over. You are wrong and the OEMs says so.

 

[keakar]

Think im gonna close my eyes and order

well just to add to your confusion,

i just bought this

CORSAIR RMx Series (2021) RM750x CP-9020199-NA 750 W ATX12V / EPS12V 80 PLUS GOLD Certified Full Modular Power Supply​

it was on sale for $100 at newegg, but im not sure if the $20 off deal ended yet, if it is you can still get it on ebay for $99 here

CORSAIR 750W RMx SHIFT RM750x 80 PLUS Gold Fully Modular ATX Power Supply | eBay

i dont ever believe in buying the expensive stuff, but i also dont cheap out on certain things like PSU where the quality maters more than price

why even bother with bronze category, just make your pick from the gold versions

What? Talk about misinterpretation: nowhere did I (nor Dro, unless you quote it for me then I'll apologize) say that the PSUs aren't safe unless overpowered.
I EXPLICITLY said the USER'S DATA will be safer if he opts for a little PSU overprovisioning to avoid protections tripping.

When 650W is enough, overprovision to 750 for a safe experience

once again, discussion is over. you are wrong

 

[nomdeplume]

He said they might consider playing it safe it by having an extra 100w if they think their power use might expand.

I played it safe going with a known good performing PSU.

Pedantry of this nature would be quickly resolved if the OP cared to ask a mod to remove it.

 

[Bill_Bright]

dirtyferret is correct. There is no technical reason a 750W supply is "safer" than a 650W supply just because it has a higher output capacity.

There is no technical reason a 750W supply can more easily or more safely protect the connected equipment from "transient" spikes any better than a 650W supply. None whatsoever!

It is the design of the power supply, not the output capacity that determines how well the supply will suppress such spikes.

This got out of hand.

I never said that a power supply's capacity in itself is what improves its safety record. It just so happens that higher wattage units tend to be built better, especially on the same platform. Nor does that address the point I was trying to make all along: you could have the world's most brilliant PSU design, once you've maxed it out for any reason whatsoever, it's going to - and it should, or you are potentially dealing with a fire, or at least toasted electronics really soon - shutdown. Bye bye to your data at that point. Which is entirely why buying a slightly larger model than you need a wise idea.

Laser-focusing on one aspect of safety - that of hardware safety i.e. avoiding fires, correlation does not imply causation; it is not because a power supply is of larger capacity that it is less likely to blow up - it is a fact I never disputed and am in agreement with - but it does not paint the entire story either, and that was my entire point to begin with.

I consider reliable operation and data integrity to be part of the word "safety", but if you don't, that's OK, it's just a conflicting philosophy, perhaps you do not value the data the computer is processing enough to invest the extra into something that will last longer, and that is no crime, I just don't see how either of us could be in the wrong here.

While we're talking cheap power supplies, I found my apevia 600w to be very good. Its the 'APEVIA Prestige Series ATX-PR600W' its only $60 and now before you gasp in horror, apevia has really cleaned up their act in the last 10 years. Its gold rated and in my experience, more reliable than that antec peice of crap I bought once for a premium price that fried my system ( that might be why I an hesitant to buy 'high quality' power supplies, especially when I already have one that works.)

This is 100% untrue, if its the same line & platform it's practically 100% identical parts with the same care of construction by the OEM. It's not like you run a SMT assembly line different for a 650w to a 750w of the same consumer line. There is very little you need to change to make a 750w unit into a 850w or a 650w into a 750w. You are just pivoting to change the subject.

 

[nomdeplume]

Abstractions belligerently enforcing a side point narrowly, at best, related to the direction conversation has pursued are indefensible.

There remains exactly zero capital S underscore bold scare-quote safety concerns with the PSU under discussion.

Alright man, I don't wanna argue this anymore. I could point out that there are PSUs of the same series that use different OEMs, for example, but it's just lengthening something that has veered off topic and become, to be honest, rather toxic. Let us be at peace brother.

I agree

 

[dirtyferret]

I'm actually going to surprise you and defend you on this...partially. This was more common years ago with brands like Corsair and Antec. Antec would flip flop between OEMs like Seasonic, Delta, CWT, and FSP sometimes in the same line. All high quality OEMs so stating one is better than another in build quality is a reach. They really don't do that as much now, same with most other brands due to how production costs work and the current competitive market. Corsair is another story as they are hands on and design the units alongside their partnered OEMs which allows them to take the build to another OEM but build quality still has to meet their standards and their in house testing is excellent. Thing is many people remember the original VX450 & TX650 fondly, both built by Seasonic. The higher watt VX 550 , TX750, and TX850 were all CWT units. People preferred the lower watt because they were Seasonic, I believed they were all very good units at the time with equal build quality for each unit of each line. Corsair has taken their unit lines between OEMs like Great Wall, CWT, Chicony but the build quality was always to their standards. The only one that really stands out in my mind as dropping the ball a bit was the RGB CX750F built by HEC. Not really part of the true CX or CX-M lines built by CWT and then Great Wall and not really up to their quality but once again it was a higher watt unit where the lower watt units were better built.

So yes accurate different OEMs in the same line, more so back then, but not always having the larger watt units built better.

*I'm 90% sure the OEMs are accurate but too lazy to check each one. Definitely on the Corsair TX, VX, and CM lines.

You certainly implied that, at least twice when you said more than once.

overprovision to 750 for a safe experience

It just so happens that higher wattage units tend to be built better, especially on the same platform.

Tend to? Same platform? No, dirtyferret was right again when he said,

This is 100% untrue, if its the same line & platform it's practically 100% identical parts with the same care of construction by the OEM.

Well, maybe 95% untrue because there likely are units "marketed" as being in the same "line" but in reality, do NOT use the same "platform". You make a valid point @Dr. Dro about different OEMs being a possibility. But those are exceptions, not the norm.

That said, a different OEM does NOT automatically imply a drastically different "platform" or design either. In fact, it is not uncommon for companies/brands to outsource production of the exact same design and specs to different OEMs to (1) increase supply and (2) have more than a single source (in case, for example, one factory burns down, if flooded or blown away in a cyclone).

I will also note @Dr. Dro is partially, perhaps mostly correct about some lower wattage supplies being of lessor quality. But, these days, those "tend to" be much lower wattage supplies like 300-350W or less, and from off-brand makers.

Transient spikes were mentioned more than once. There seems to be some misunderstandings about them. I note transient spikes commonly are well up into the several 1000V range. 5000 to 6000V are NOT uncommon. Fortunately, they typically last less than 10 µsec (10 millionths of 1 second, or 0.000010 second). There is absolutely NOTHING to suggest a 750W supply can handle such a transient any better or more "safely" than a 650W supply just because it has a higher "output" capacity.

What you think about the vertex 850w for just more 15€ ?

 

[dirtyferret]

What you think about the vertex 850w for just more 15€ ?

quieter fan profile (same fan but seems to make less noise), newer design & cleaner layout for better airflow. Box and reviews say it has a 10 year warranty yet Seasonic paper work and web site says 12 years (I believe 12 is the accurate number but not certain) . It's a very good good PSU and a notch better than the GX but will a user see the difference that won't be pushing the PSU to the limit? Probably not. Also, it's kind of over priced and the competition has just as good or a hair better units for the same or less. Once again its not like you would see the difference. To me, it's not worth the 15 more over a GX. To other people, maybe and that's fine. If you are pushing the unit to extreme levels the quiet fan profile may be worth it but at the same time you could just go to a higher watt GX for the same price. Maybe the 12 year warranty is worth it to you but honestly there is no real world difference between 10 and 12 year warranty and most people are looking to move on after a decade with a PSU to something newer and more modern.

Literally on their own web site the box says 10year warranty for the vertix

yet on the same page it says 12 years on the warranty twice (including just above the video) plus on the PSU paper, Seasonic marketing team is no where as good as their design team (not the first time they messed up their info)

Thanks alot.

There so many PSU ,

ATX Thermaltake Toughpower GF A3 850W TT Premium Edition 80 Plus Gold Full Modular​

Even cheaper than the focus 750 GX with the promotion and this one its 850w , its so stressfull....

 

[nomdeplume]

Use your best judgement if the extra cost is justified.

it would compete with units below the GX series, ok but nothing special.
There is definitely a paralysis by analysis feel to PSU once you get above a certain level where as nodeplume stated, is the extra cost justified to performance I would use/benefit from for my needs. All three PSU you listed will do the job, I would pick the GX Seasonic at equal price with the Corsair and 15 below the Vertex (which is the best of all three).
