Which PSU maker is the most reliable?

Veseleil · Dec 25, 2022

Apples and oranges.

RBit · Dec 25, 2022

It should also be noted that all the the different vendors will use different manufacturers for different products in their psu portfolio, for example Thermaltake might use Super Flower for one PSU, and Seasonic for a different model. So it's not as easy as associating one company with one manufacturer. You have to know which vendor was used for a specific model.

Yup corsair heavily does this, evga as well

Hi,
Mostly super flower
All I have is evga P2 series 750-850-1000-1200w which are SF.
Evga just slaps their logo on them like many others do.

As you know, most of PSU's are developed in a handful of corporations. Even Corsair, Asus Thor, MSI, Cooler master, Evga are regular customers of this companies.

As far as I know these companies are Seasonic, FSP and Channel Well Technology. So which one is the best (or well known) PSU maker? I know the specific model matters the most, but in general terms which brand would you pick?

Seasonic | Power Supply for Computer

I don't know ANY PSU made by purely CWT. Though I know they are OEM for many brands lol.
For me, Seasonic is go to, FSP is not as good nowadays already as it was like 10-15 yrs back.

Super Flower are the manufacturer who makes everyone elses psu's, they only make psu's and they are smart enough to use Japanese capacitors which is important because Chinese capacitors are usually a smaller capacitor in a big capacitor case. I also like EVGA power supplies and really anyone who offers a 10 year warranty on their product is generally reliable.

Why Japanese capacitors is an important requirement, if you look in the 2200milli farad cap there's probably a 600mf.

I know it's not common practice but I normally do capacitance reading on all my capacitors.

Eskimonster · Dec 25, 2022

i swear to Seasonic, and i only buy them with 10 years or more warranty.

I would question that claim.

oxrufiioxo · Dec 25, 2022

I personally stick with Seasonic or Superflower but there are plenty of other good platforms out there and sometimes it even comes down to who refreshed their lines most recently.

There are a few others, HEC comes to mind. There is a list of PSU's graded by Cultists, I like to rely on that.

PSU Tier List rev. 17.0g - Cultists Network

PSU Tier List will help you to choose the best PSU out of hundreds of models on the market. From budget to the highest end Power Supplies.

cultists.network

MSI has a few A-tier Gold (Best units in the tier) and Blue (Quiet operation) models

Interesting!

Given it highlights specific issues in quite a few different Seasonic PSUs, I'm gonna sway towards Super Flower as the best one personally.

kiriakost · Dec 25, 2022

If highest energy efficiency score along 10 years of warranty, these are not at consumer top list?
Then all PSU they look identical with the top cover closed.

Only skillful people in electronics they have complete awareness of how challenging it is, for engineers team, them to combine 120 electronic parts or more, so them as one, to deliver higher efficiency.
The big spenders which classify them self's as E-Sport gamer, they should better wait for the upcoming Seasonic Vertex series for the latest MB and RTX cards.
When 97% of consumers they will be totally happy with the Seasonic Prime.

I did refurbish recently and still using my PSU of 2008, I did feel good for a few months about this personal success, because I was not forced any more to toss away 200EUR for a newer PSU.
Nowadays the electricity bill this become more expensive than the price of a new PSU.

Priorities changed over night and we have to adapt in a new way of dealing with computer hardware.
When electricity bill this overloads due four PC in a household, this translates to huge waste of family income.

Eight months ago, here in TPU I did wrote of my new decision about me to get the Seasonic TX750 PRIME as my next PSU upgrade.
This summer I got the Seasonic TX750 PRIME as product sample, my test lab needed some test equitment upgrades and my review this is on hold.

In conclusion, what ever I write today this is facts of my past made homework, as of what it has to do with Seasonic customer support?
In my region no other PSU brand measure up.

We working in electronics repairs professionally, we do not have Gods, we only admit the superiority of a new product if there is found any.
And this is the purposed served due PSU product reviews, because due accurate made electrical measurements we discover the truth.
Simple as that.

Shrek · Dec 25, 2022

An interesting point

Let's say I could save 20W by upgrading my PC power supply; 1W costs about $1 a year out here (24/7 use), so if I use the PC 8 hours a day, I'd be saving about $7 a year

lol. Don't spend it all in one place.

Count von Schwalbe · Dec 25, 2022

It is interesting though, if you plan to run the rig 1/3 of the time for 6 years, is it worth buying a pay with a higher efficiency? Maybe, if it only costs $15 more in the swamp.

Shrek · Dec 25, 2022

I'm a lazy guy and would rather recap the old supply than figure out a replacement, and I'll have you know that I live in one of the most technologically advanced swamps in the land!

We PC power users, we have different work hours, and requirements..
Large businesses with much more installed PC they benefit more from what a single PC user will.

I don't doubt your swamp, but other places (Europe) they have more expensive electricity...

adulaamin · Dec 25, 2022

Seasonic and SuperFlower for me.

mclaren85 · Dec 25, 2022

@kiriakost hello again, I know this is an off-topic question but I really want to know what makes the difference between the brands?they use the same capacitor, same PCB, same transformer etc.. which component is the reason to be called premium?

Shrek · Dec 25, 2022

I believe most power supplies use different PCB layouts, that the transformer is not the same etc

Veseleil · Dec 25, 2022

TBH, power supplies in both of my main machines come from an ex-mining rigs. And I will continue to buy those, as it's the only way to get my hands on to higher tier units for a fair price. They are mostly overkill in terms of wattage, and most of them didn't work for too many hours anyway. People used to jump into cryptomining fast, and jump out of it much faster. :laugh:

The only thing that might need servicing is a fan. Using an Arctic F14 on my Rosewill Capstone 1000M (SuperFlower golden green), drilled to fit the 135mm factory fan mounting holes, it's powered & controlled from a motherboard fan header (fixed ~600rpm in BIOS). I also had to clean the internals, as you could guess, no one ever did that. On the other hand, the Enermax Revolution X't came almost in a factory condition. The seller cleaned the internals almost perfectly, and the fan still goes strong. Just for the record, both factory fans are double ball bearings, and while the Enermax one makes tolerable noise, the Rosewill one (globe Fan) I had to replace. It's one of the noisiest damn fans I've ever encountered.

Shrek · Dec 25, 2022

It is risky changing out a power supply fan with one that might not have enough flow.

Kalo vradi,

There is a local Seasonic distributor in Turkey and I even e-mailed them to ask to stock however there were no reply. So I did contact to Seasonic HQ, and they replied in less than 2 hours. In the box, Seasonic says it will provide a full 10 year warranty in Turkey, official distributor declared as two years.

Any case, I'm a Seasonic lover.

Wow, that's sounds like a scam from the distributor.

lightning70 · Dec 26, 2022

in my opinion Seasonic.

I think you're Turkish, I'm Turkish too. I have read reviews and experiences about many brands so far, Seasonic is top quality and hassle free. MSI and ASUS PSUs seem to be made by Seasonic.
