Are Seasonic PSUs still regarded as the best in terms of performance, sound levels and longevity? I have had 2 Seasonic PSUs and my last PSU was an Asus Rog 750w which I believe is built by Seasonic. All of them have performed well, were very quiet and lasted years, so I'd like to get another one, or another brand that is built by Seasonic. Only reason I am asking is I looked at the spec me threads and I hardly ever see anyone recommend Seasonic PSUs. Just wondering if something changed, or if people just get the cheapest PSUs as its not an exciting part of the build...

Also does anyone know if the new Asus Rog Strix 1000w PSUs are made by Seasonic? I was going to order one, but I don't like the idea of the fan being a cheap double ball bearing fan as I want it to be quiet. If it isn't I might just go for the Seasonic Focus 1000w for less money, which has a better fan, but is gold rated instead of platinum.


Thanks for any input
 
Are they still good? yes and plenty of other OEM are using their internals still, the market last few years has been flooded by new 'brands' branching out at different price points.

It's over kill for what you need but there are plenty of us out there running 'flagship' Seasonic PSU's such as the Noctua edition 1600w.

At a 1000W I'd be looking at the Phanteks offering especially as they generally come with braided cable sets.

Not really, they're just not the best at their price points and availability isn't great.

The HCG Pro I'd say is the most popular Seasonic-derived PSU (Vertex Platinum) on here.

Yes, the original Rog PSUs were based on the Focus.

I don't believe so. SPL's tier list says they're built by Great Wall (if you mean the Platinum ones).
 
Thanks for the replies. Qtec is a blast from the past ;) I did a bit more digging and I couldn't find Seasonic in any of the 'best 5 PSU' lists and the site with all the in depth reviews doesn't seem to rate them too highly now. I guess I'll look at other brands and see what is good now.

I have removed the Rog Strix from my list as I don't want to compromise on something that will annoy me down the line with the fan being reported as noisy under load.

Currently looking at the Be Quiet dark power 14 as its supposed to be very quiet and perform well. Although Its apparently made my CWT which back when I used to keep up with the PC market was one of the oems that made mid range PSUs.

Nobody recommends Seasonic because they are so expensive and there are many cheaper options.

But if you look at tests they often beat the competition and are very modest about the wattage rating.
 
Yeah my 750w Seasonic is currently handling my new 5070ti fine, despite some of the calculators saying I need 850w. I have an AM5 motherboard on the way and am planning to get the 9800x3d with an AIO cooler and Nvme drive, so it might be pushing it a bit. I'm kicking myself for not going with a 1000w at the time to give me more headroom.
 
I've bought and owned a few Seasonic PSU's over the years, compared with some PSU Manufacturers these days they make a fair amount of Peaches and a few Lemons. I've had one fail on me, that was a X560 which was replaced under warranty.
I bought an S12II, didn't like that at all. The 1st Generation Focus 550 watter was pretty good though. The S12 430 watter 1st generation I bought in 2006 served me well and powered a fair few of mine and my familys rigs over 15 years.
One feature on all of them I liked is that they were all Quiet.

If I were to buy one today it would be either one from the Focus range or Prime range. I'd give the core models a miss.

An alternative would be to buy a brand of PSU that uses Seasonic as their OEM, I believe Seasonic specs older models for these brands but they are still OK for most people.
 
Seasonic like all companies can and will make both good and bad power supplies, and everything inbetween. Don't get me wrong, they have some fantastic options and tend to release quality units more often than not.

Other companies and OEM's make just as competitive and at times better power supplies, I'd have zero issues buying from the likes of CWT, HEC, Superflower and a bunch of others.

CWT will pretty much make a platform as good as their customers are willing to spend/ask for, they actually make some of the best supplies on the market such as the Corsair HX-I.

This is worth bookmarking/checking over when you're on the market for a PSU but aren't sure about what to buy:

Yup, exactly this. Seasonic are consistently one of the better psu makers, but you should be looking at models rather than the brand. That document is the one to consult if you're in the market for a new psu. Also check the warranty. Any decent unit will come with one that lasts 10 years.
 
My Seasonic Focus Gold hasn't skipped a beat. As others have said, most companies have both good quality and low quality PSU's for sale at different price points.
 
Oldest PSU I still use is an 860 watt Seasonic platinum from 2012 or 2013. It might be going bad now but only just started diagnosing the issue - sometimes when switching on the PC there's nothing at all, like a dead PC. Some minutes later however it can suddenly boot up. Same for coming out of standby also. Could be something other than the PSU but can't complain if it is after 13 or 14 years of use.

Exactly. The same principle applies to all brands. Most have good and bad products in their range.

For me personally I’ve always stuck with Seasonics titanium range and never had any issues.

The only other power supply I’d consider at the top end is Corsairs AX-1600i. The rumoured refresh will likely be the best power supply you can buy when that eventually releases….
 
Still a genuinely top brand. Just to a Titanium model and it's been solid so far; have used them for a while. Brans are brands, but generally speaking they make decent units
 
i still stick with seasonic
not exactly a bar to pass but still
im using a focus gx1000 on this main pc im using now and i just recieved a sgx-650 i think it is for a m-itx build
thats about to happen. also still have a gx-750 as backup and my old gx-550 i donated to a friend is still also on
heavy useage duty in his pc.
so i still rate seasonic
 
I'm stiil using my Seasonic PSU. They seem to be the best in detailed reviews but I haven't seen newer reviews of them as I haven't been in the market for a replacement, but it seems fewer people have them nowadays or know about it.
 
Looking at the SPL tier list, the newest spec PSU is 2024. All of the Seasonic PSU's OCUK stock are ATX 3.1 so they have been manufactured recently. The Vertex & the Prime range have a 12 year warranty, I think that is the longest warranty you can get on a PSU as most of their competitors offer 10 years at most. When you consider taking that into account if you are a periodic upgrader (like me) I think that is a price worth paying if you value a warranty of that length.
