Which one for me, between Seasonic, Corsair, and Superflower for reliability?

hi..

i'm looking to build my 1st pc. i'm a bit confused which PSU i should get.
I want the PSU to have reliabilities to survive many years,, when i upgrade my system down the road (maybe in 2 years or so), i wanted the PSU to last that build, and hopefully another one after that as well.

Initially, i was deadset on getting Seasonic G-550. but there is no availability for the item on the island where i live. (it cost $130 here)

i could stretch my budget a bit,, im thinking of going Corsair RM550 Gold ($147) because it's optimized for silence and im building a quiet pc, but from reviews.. im really really worried abt getting Corsair RM due to its capxon capacitors...

another alternative im thinking of getting is the Seasonic X560 ($172), but $145 is my maximum limit for PSU..., secondly im concern about coil whine on X series that i read on some online forums...

another alternative i could get is Super Flower Golden King Platinum 550W ($140), im not familiar with the reliability of the brand Super Flower but from the website i read that it has eco mode where the fan don't spin until 20% load so that's great.

another alternative i could get is going Seasonic G series but go higher, there is stock for Seasonic G650 ($147) i heard. the cons of Seasonic G650 is that it's probably overkill for my PC build thats all.

All the PSU above is within my budget except for Seasonic X560... i'm willing to pay for X560 if its leaps and bounds more reliable than the rest because i want to use the PSU for at the very least 5 years down the road.

Which one of these in normal situations will be more reliable / last longer and fit my needs of quiet and reliability...?


===
my build will be on 24/5 for uploading and downloading, stock speed, no OC, will never Crossfire

i5-4570
MSI H87-G43
1 SSD 4 HDD
650ti boost / 660 / R9 270
Corsair vengeance 2x4 gb
Corsair 330R

down the road i will get Blu-ray internal drive, a 2.0 speaker, and probably a sound card.

cheers ^_^
 
Johnnyguru has reviews. http://www.jonnyguru.com/modules.php?name=NDReviews

As a matter of fact, he used to post here. lol

There are several brands I could buy if I wanted to. That being said, the last time I bought one it was a Seasonic S12 II.

There are some PSU calculators that allow you to see the maximum wattage you're going to use. This my own personal preference but I prefer buying a power supply that's 150 watts more than what I need. Why? Because I find the PSU stays way cooler when you're playing games.

I have an old machine (maybe 7 years old) with a Seasonic PSU, Scythe Ninja (CPU heatsink), HIS 4670 IceQ video card and Coolermaster case. It's almost dead silent. I put the 120mm fan in the case next to the CPU heatsink but it's on the case, not the heatsink. And the video card has the IceQ type of fan that is very quiet. So only two fans in the computer with a case that has a mesh front.

EDIT: Whoops, I just noticed HIS only sells AMD video cards. When I compared the 4670 vs Geforce 8800 GS, I found I preferred the Geforce card in Unreal Tournenament 3. I only wanted to mention the video card because of its silence.

ive read the reviews on some of them

read corsair rm and seasonic g reviews. read super flower golden king review as well. but im still confused. the aftersales where i live is almost non-existent. so provided that i get a decent functioning unit (not a lemon), i'd rather choose the one that will be most reliable down the road since... when i upgrade my computer i think i wont buy a new psu with it.
 
Well I can vouch for Corsair (though all the ones I own are manufactured by Seasonic) I would say seasonic #1 if your number one concern is reliability, Corsair right behind them only because of the other ODM they use on some models.
 
OP with that grade of card and no OCs, you are getting WAY too much PSU there. Look at 300-watt units. That's still a ton of overhead because you won't break 200 watts in use. That will help significantly given that you are on a tight budget.

i know... but like i said, the G550 ($130) is empty.
Seasonic M12II-520W ($108) is also empty.

Other than the above i mentioned on post #1.. i think they have Seasonic G450 ($120) and Seasonic X460 ($168).

they dont sell 300W PSU here sadly. 400W-450W PSU only sold on Gold and Platinum efficiency... Bronze efficiency all starts from 500/550W.

Wish i couldve get some Antec VP / Neo-Eco 400W from newegg, but cant sadly

===============
also, is this wattage calculator overstated watt needed?

Seasonic is good, although in the last year I noticed significant complaints about coil whine, reliability wise they're still great. Superflower has been getting good reviews lately too. I got rosewill 500W fanless PSU which is a superflower rebadge, and it's been great, zero coil whine unlike seasonic gamble, completely silent. Corsair does not make their own PSUs, they source them from all over, some models are made by seasonic, some by channelwell, and who knows who else. Not sure who makes RM series but from what I understand it's not seasonic. So of all your choices, I'd go with seasonic, you might get a unit with some coil whine, but reliability wise it's your first choice.
 
they only have rosewill hive here and that's also empty.
considering i can't stand coil whine, my ear is unlike average ppl ear 🙁

i've heard about X series whine.. so now i narrow down my choice to g650 and sf golden king i guess, depending on availability.

does anybody knows if seasonic g series also whine like x series does?
 
The Seasonic coil whine is a gamble. I still visit silentpcreview and other forums and from what I understand 1) the coil whine problem can affect gold, platinum, and fanless seasonic PSUs 2) some PSUs are better than the others, i.e. they have less coil whine or none when powering the same machine 3) sometimes the choice of components can affect the whine. Basically like I said it's a gamble, completely unpredictable. Of course it also depends on a person, some people are bothered by it, some cannot even hear it at all, so from their perspective there is no coil whine at all. Personally, I'm highly sensitive to noise, especially coil whine. I actually unplugged our HP inkjet printer at home because we rarely use it and I noticed it has coil whine when plugged in. I bought Anker USB charger mini station because my Nook HD+ power adapter is making noise without any load, I subsequently returned Anker adapter to Amazon because it had sporadic coil whine when my tablet/phone were almost charged and I'm back to using stock Nook power adapter.

JonnyGuru actually gave very high marks to the SuperFlower PSU, so if you want to be safe, I'd go with that.

Look at the XFX PRO 750 W Black Edition Full Modular Review at Hardware Secrets:http://www.hardwaresecrets.com/arti...Edition-Full-Modular-Power-Supply-Review/1695

It's a clone of the Seasonic X-Series KM3 design and priced much cheaper then either Seasonic or Corsair units.

I bought the XFX PRO 850 W Black Edition Full Modular for $120 from NCIX.CA about a year ago and it's been a fantastic unit - Quiet and no coil whine.

These units are Gold Rated but pass Platinum Specs when tested.

Corsair does not build their own PSUs, although they do specify how they are built (circuit design, component selection, etc).

Super Flower makes good PSUs, so buying one of their units will not cause you much trouble either.

How do you like your Super Flower?

I've got what I think is the Rosewill equivalent:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817182169

Had it about 3 weeks. No complaints at all. It has no coil whine, which I wanted to avoid and which is often found on Seasonic fanless PSUs.

I paid 120, which will amount to 80 net if I get the 40 dollar rebate I just filed for.

Cables are more flexible than I was expecting, which is good. I have all 3 internal drives connected to a single SATA power cable.

Only minor quibble is that it's only "semi-modular"---the video card cable that most people would use isn't detachable. I don't use a video card, so I simply tied it up and out of the way into an unused drive bay.

I've got it mounted in the top of an Antec Solo II case, with the PSU heat sink immediately below a similarly sized vent in the case. In a warm room (27C, 80F), the heat radiated out of the vent isn't even warm unless the PC is under a considerable load.

I think there is a 430 watt model available in Europe through Superflower, but I could not find a USA source.

No regrets, but I can't really comment on its reliability since it's so new.
 
There's something you may want to consider. Note that the below is from personal experience only and that I am from the US.

When my Corsair psu went bad, they shipped me a brand new sealed in box replacement. Same when my Corsair H60 died.

When my brother's Seasonic psu went bad, he had a heck of a time trying to get in touch with customer service. When he finally got them to respond and shipped his unit back (own expense), they shipped the same back to him without doing anything.

I don't doubt Seasonic's quality and I have one as you can see from my sig. But it will be my last Seasonic and for me it's Corsair all the way from here on out. I don't know how much you value customer service or if you will have that experience if you aren't from the US. All electronics can fail and all companies put out a percent of defective products. The differentiator for me is how each company handles it when it happens.

OP, you named the 3 best makers of PSUs in the world. your question is irrelevant.

Well, Corsair doesn't actually make PSU's. And if we're considering PSU brands, I'd place XFX and Antec above Corsair in overall quality, especially in the mid range. Corsair's high end units made by Flextronics and Seasonic are top notch stuff, of course. But RM series uses Teapo capacitors instead of the highest quality Japanese ones, so I wouldn't put RM series next to Seasonic G/X series or Super Flower Golden King.

I can personally attest to this. I think I am the who handled that RMA 😉

Thanks for sharing that experience btw.

I think you are referring to the Chicony RMs here. We've recently EOL'd those SKUs, both the 750 and 850 are no long being built. We are moving our RM to CWT as our OEM from this point on. The RM updated version will have 100% Japanese Nippon Chemi-Con caps on both the primary and secondary.

Nice! But I was actually referring to the first CWT built RM units, of which JonnyGuru reviewed the 650W version, noting Teapos and CapXons on the secondary side:
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=363

RM1000 is the same - CWT with filtering by Teapo and CapXon:
http://www.techpowerup.com/mobile/reviews/Corsair/RM1000/4.html

Are we going to get all-Nippon versions of the RM450, RM550, RM650 and RM1000 as well?

well yes, you caught me trying to cut it short. still, we've all read the reviews of the corsair parts and you know how good they are, even with the "subpar" capacitors.
not that modern capacitors fail as they did 30 years ago.

also, corsair's rma is legendary, and the thing where they took responsibility for a system damaged by a failed AIO .. thats stuff that leaves a mark. for my new system i got corsair ram and corsair psu without a thought

@joseph
if you read this, next step is to work on your cases range. take heed of the complains about the weak side panels.
(check out Define - they are doing some incredible work. surely you can do better?)

I think they're already released. Newegg:

RM850
RM750

Both claiming to have high quality japanese capacitors.

I honestly don't know if those are already the CWT units, but I can get a confirmation from our PSU team.

Edit: Confirmed, those units are already from CWT.

Thanks for the kind words, I really appreciate that 🙂 We'll continue to do our best to make sure that customer experience with our after sales support is always a positive one.

I'm with you on those side panels, we'll surely need to improve them somehow. That's a very good feedback, duly noted.
