We need more things like this. Low wattage high efficiency goodness.

R-T-BWe need more things like this. Low wattage high efficiency goodness.

They already have Focus plus series fitting that category. With higher efficiency video cards(atleast from nVidia) high wattage PSU aren't necessary as much.

My next PSU will be an Seasonic Prime, maybe this one, depending on the price in my country.
I really like that 12 years warranty.

Seasonic is just brutalising the competition lately. First they release the PRIME series which beats the snot out of anything their competitors have in terms of performance, has a warranty that will outlast multiple generations of systems, and is priced highly aggressively for what you get. Then their competition starts spreading rumours that Seasonic cherry-picks review samples, so Seasonic calls their bluff and gets reviewers to buy retail samples... which perform identically to the "cherry picked" units.

Now they add yet another PRIME variant that's even better than their existing line. It's like Seasonic dropped a building on the competition, and this new PRIME is an extra brick they are throwing on top just to push their point home.

Seasonic has no chill this year, and I love it.

why do i need such a great higher cost psu if the other components are decreasing in power requirements?

Glad to see SeaSonic making moves on the mid capacity PSUs. Until recently most high-end quality PSUs are all 650W+ units.

I'll be getting one of these PRIME Ultras the next time I upgrade my secondary box. That PSU tester will be a good extra to have provided that it would work with any brand of PSUs.

A good PSU is an investment that will literally last you years. Until now, the really good PSUs have only been available at high wattages and proportionately higher prices. Seasonic is bringing the wattages down but keeping the quality so that more people can afford PSUs that perform well and last long.

but many psus perform well & last long, my corsair tx750 from 2008 is still in use

seasonic already has great quality across pretty much all of its lineup, choosing its 'lower end' models isnt much of a compromise compared to this prime ultra, which says it comes with a 'psu tester', an added cost i have no use for, it's a convenience not a requirement

My Bequiet 720W from end of 2015 wen belly up after its warranty period... turned it on and fire on the input socked side not so nice


bought a new seasonic prime 650W for 130€ and i am loving it. Will be inside my rig by friday for weekend gameing..

To save money for one , key words ( more efficient ) . Many people have been using Seasonic units for years without knowing it with rebadged PSUs from enthusiast brands. The PSU market is very competitive keeping seasonic units a bargain for what you get.

It takes years to recoup the initial investment from PSU's efficiency, that's not the reason to buy these. Knowing it will go for years with no fear of frying something on your motherboard or dying on its own when you least expect it, that's a good reason to get one of these. Plus, they're quiet, modular...

I picked up the 750W Prime last year for $110 after MIR. Out of all the components in my build this one will outlast pretty much everything except maybe my case. Even though I bought my PSU before the extension to 12 years on the warranty, they grandfathered me in, Its rare to see this kind of customer service and treatment out of a manufacturer. I can say I'll be a longtime Seasonic customer (not that I'll need more PSU's with a 12 year warranty).

Not frying something saves money...no? As of today on the egg Seasonic 650w titanium full modular ( no 550w yet) and Silverstone 600w titanium full modular are both $149. . Final price with rebates and shipping Sea. $134.90 , Silver $145.98. (With Seasonic having 50 extra HP ) With more reviews having Seasonic with higher efficiency you don't need years when you save from day one.

note my last post; from within seasonic's entire lineup, which is not going to suddenly destroy everything, which has a minimum amount of decent efficiency, which isnt loud or unstable, what is so good about the n-times higher cost of ultra/platinum other than small numbers & a useless psu tester?

so.... i was about to pick up another Prime PSU from my local microcenter, only to find out that the "prime" titanium PSUs have now been replaced by "prime ultra" titanium, but neither are in stock. WTF is the difference? someone pleas enlighten me.

EDIT: found the answers. they removed the cables caps and added support for SATA 3.3

kn00tcnwhy do i need such a great higher cost psu if the other components are decreasing in power requirements?

...because the PSU is the only component that can literally cause issues with any component if voltage regulation is off and is the only component that has the potential to fry just about every component in your machine. To me, that's reason enough to not cheap out on a PSU as I've seen cheap PSUs wreck machines when they decide to fail.

The TX750 is made by Seasonic, isn't it? :laugh:

the cheapest most low end seasonic is going to fry every component in a machine? this is common for known brands!?

why do i need an ULTRA TITANIUM PSU WITH PSU TESTER for $300, i never mentioned a $20 800w noname explosion psu, but electricity doesnt have a disaster at $100

My point was just buy a decent PSU and not the cheapest off the shelf and you should be good. In addition to that, Seasonic tends to make good units but, cheap hardware is cheap and you get what you pay for.

Once Enermax was No 1 probably. Now they can't catch competitors.
Seasonic, Super Flower lead market. Flextronics very rear show up on desktop market and than maybe even outperform them.
But one more player is forgoten who could outperform maybe all of them, Delta Electronics. Antec HCP 1000 Platinum is tank.
Very bad because none of them didn't build PS Case I like, In Win C900. PSU with aluminum case but significantly lower quality then this models and really not worth to buy PSU because nice case.

Seasonic removed their famous Sanyo Denki Industrial fans from PSU. Probably because noise.
Their sacrificied durability for silent operation.

Recently purchased a PRIME Ultra 550W 80 PLUS Gold Power Supply, Full Modular, 135mm FDB Fan w/Hybrid Fan Control, ATX12V & EPS12V, Poweron-Self Tester,- 12 yr Warranty (SSR-550 GD v2) for $84.99 & FREE Shipping.

However I could have gotten a Seasonic Focus Platinum for $99.00 comes with a 10 year warranty. The Focus Platinum has a slightly higher efficiency rating of 92% at 50% load, where the Prime Gold is 90% at 50% load. The Focus Platinum Voltage Regulation [± 3%]
(3.3V 5V 12V) and the Prime Ultra Gold a Micro Tolerance Load Regulation (0.5 %). Other than that I'm uncertain of other differences.

The Prime Ultra is $15.00 less and comes with a 12 year warranty.

I have a M93p Thinkcenter with OEM 280W power supply and wanted to add a Nivdia Quautro K4000 video adapter (3GB). PSU calculator told me I could squeeze by with a 350 Watt PSU so I started looking at 400 and 450 watts power supplies from Seasonic and OEM Lenovo's. Most were non modular where some were semi modular. All came with a maximu 5 year warranty

Ebay has Seasonic 400 - 450 watt PSU's that are listed as new, pulled from new PC from around $30.00 to $60.00 and other Seasonic 550W - 600W from $60.00 to $100.00+

However pulls have no warranty at all the others it wasn't clear some may have had up to a 5 year Seasonic warranty.

Also some may not of had the correct type of PCi-e power connector for the K4000 that uses a 6-pin (3+3) connector.

Anyway I'm happy with the SSR-550 GD v2 that has a Gold certified 90% efficiency rating which is better than most other Gold series PSU I've looked at.

I also have a P300 Thinkstation that came with a Lenovo 450W Platinum PSU, that runs new around $150.00+ if you can find one most the Lenvo 450W are a Gold or Bronze series. and run around ~$100.00.

I doubt I will ever need to upgrade the video adapter again as I haven't been doing any gaming at all. Mostly Video, image editing and mapping and map making.

Video editing / image softwares don't normally utilize much Video ram as does gaming.
