Seasonic PRIME Titanium 1000W Power Supply

Seasonic PRIME Titanium 1000W Power Supply

When it comes to neat cable management and high-performance output, you can consider this seasonic 1000w PSU. It is an SSR-1000TR 80 Plus Titanium ATX12V & EPS12V fully modular power supply. With the 135 mm FDB, the cooling performance is excellent.

Seasonic equipped this power supply with a PSU tester inside the box. It allows the consumers to carry out a rapid and simple jump start on the power supply. Every PRIME Ultra Series power supply would also contain a SATA 3.3 adapter. This adapter supports the “Power Disable” (PWDIS) functionality of the latest, high-capacity hard drives. The wide compatibility implies that this prime titanium 1000w PSU is one of the best seasonic power supplies.

To make the system lightweight, the inline capacitors on the cables were discarded. The 180° SATA connectors are flexible and easy to install. Seasonic has employed the latest design feature in which instead of cables, the rear panel, and the PCB are connected through a copper plate. The corresponding breakthrough solution not just reduces the odds of errors during manual placement but also enhances the output power quality.

Key Features

  • With the 80 Plus Titanium standard, the PSU offers 92% efficiency at 20% load, 94% efficiency at 50% load, and 90% efficiency at 100% load.
  • The latest design from Seasonic retains the output voltage in an extremely tight range. So, it achieves load regulation under 0.5%.
  • The extraordinary electrical performance and steadiness make this PSU a perfect option for high-performance systems.
  • For reducing cable clutter and boosting airflow, the PSU is made fully modular.
  • Fluid Dynamic Bearing (FDB) fans are high-performance fans devised to obtain the benefit of the impact absorbance effects of oil. They produce less heat and operation noise compared to ball-bearing fans.
  • Due to the lubrication on the bearing surface, vibration and friction are reduced. So, total power consumption stays in control.

Final Thoughts

Seasonic has been a prominent name on the power supply market for several years. The above review highlights that the seasonic prime titanium 1000w power supplies are economical and also guarantees outstanding performance.

Top 10 Seasonic PRIME Titanium 1000W Power Supply Reviews

1. Seasonic Prime Titanium 1000w vs my EVGA 1000w Titanium T2

I bought this Seasonic Prime Titanium 1000w PSU to replace my EVGA 1000W Titanium T2 PSU that developed coil whine. Both of these PSUs are extremely nice. They work great doing what a PSU does, powering the system. The Seasonic Prime Titanium 1000w is doing a great job powering my system with an Nvidia 2080TI, 9900K CPU, 8 case fans, and multiple hard drives. Overall, both PSUs are great. If you want a 1000W titanium PSU, pretty much this Seasonic and the EVGA are your best choices on the market.

Now that I have had both of these PSUs, here is what I think between the two of them:

Pros of the Seasonic Prime Titanium 1000w:

  • The PSU is actually physically smaller than the EVGA; not by much, but it was enough to immediately notice. Nice if you need to conserve space.
  • The hybrid fan control button is on the EXTERNAL side of the PSU outside the case. The EVGA switch for their version of this feature is inside the case. Therefore, the Seasonic is much easier to change this setting on, as you have to open your case to do it on the EVGA.
  • The power cables (except the motherboard 24 pin cable) are flat instead of in a rounded sleeve. This was a big help was cable management on the side of the case; with the EVGA, I had to really work to fit the case side panel on due to the bigger cables.

Cons of the Seasonic Prime Titanium 1000w:

  • The Seasonic has noticeably shorter cables than the EVGA. I have a mid size case, and I was no longer able to route the CPU power cables around the side of the case along with the rest of the cables due to insufficient length.
  • The CPU power cables are also split apart in two “ribbons” (for lack of a better word) each. This was kind of annoying because it kind of makes the cable seem like two cables when it is actually one. The EVGA wasn’t like this.

Neutral of the Seasonic Prime Titanium 1000w:

  • The Seasonic feels less heavy than the EVGA, but it could just be in my head.
  • The Seasonic makes a noticeable click at power on/off. (It does not last more than a split second). The EVGA didn’t make this click sound. Not really a big deal, but just in case such things bother you.*The Seasonic makes a noticeable click at power on/off. (It does not last more than a split second). The EVGA didn’t make this click sound. Not really a big deal, but just in case such things bother you.

2. I exclusively trust Seasonic PSUs

I bought this Seasonic Prime Titanium 1000w to replace a 10 years 750W Seasonic that finally bought the farm. It owed me nothing, and I trust Seasonic completely. I am an electrical engineer, and have pulled their stuff apart before. The circuit topology is well thought out, and the components really are of a very high quality. You can tell these guys know what they are doing when it comes to minimizing ripple, current foldback, and being able to provide stable power as the system demands it. They are such a high quality that the other trusted brands – like Corsair and EVGA – are usually just re-badged Seasonics for their high-end stuff.

I went with a this larger supply simply so I could take advantage of the higher efficiency. PSUs are always more efficient the less power you draw from them. I am normally drawing around 500-600 watts at peak, and 300-400 at idle. On my old 750W supply, that meant I was around 85% efficient at peak power usage, and 90% or so at idle. With this new one, I will be around 94% efficient at peak power usage, and about 93% efficient at idle. So, all around, I should see a slightly reduced electric bill from this more efficient PSU.

The only thing I am going to knock them for is their documentation, specifically the lack thereof. With my old middle-of-the-road 750W Seasonic, every single cable had a detailed page documenting the pin layout on both ends of the cable. With this high-end Seasonic Prime Titanium 1000w, I got a list of included cables and their lengths, and suggested cabled hookups (‘Use two PCIe cables for cards requiring over 225W’ is an example). I could probably figure it out on my own, but having that pinout is nice for troubleshooting or if I ever want to sleeve my own cables. At least some online documentation would have been nice. Ultimately though, not enough to knock off any starts.

3. For a premium build, well worth it.

I got this Seasonic Prime Titanium 1000w psu as a “used/customer return” unit for about $50 off. Not a bad deal for essentially a brand new in box opened unit. After 20 years of buying Corsair PSUs, I switched to this Seasonic unit based on recommendations from IT and computer geeks extolling the virtues of Seasonic’s current and load regulation, efficiency and brickhouse build – this one had a 12 year warranty that lent plausibility to all the computer nerd gods’ shilling of it. If you take a look at the retro analog look of this unit’s component board, I think you’ll be sold on it as well. I liked that you can look inside from the back of the unit to see the heavy-duty electronic components of which this one is constituted. I read the review on Tom’s Hardware and was impressed with the idea of the super quiet performance one got for the extra money over Seasonic’s own Focus line up. I pushed in the “Hybrid Switch” on the back of the unit for that little extra bit of quiet as well.

I tested it on my system, by keeping the case open while I twiddled on the UEFI screen’s fan Xpert and overclocking functions. I noticed that the fans on the PSU certainly switches on and off based on the circuit load – a nice gross affirmation that the unit works as promised. I just got finished building my dream computer: i9-9900k with Noctua D15s (2fans) cooling, Corsair Vengeance LPX 32GB 3200MHz RAM, Samsung 970 M.2 NVMe 1TB boot disk, Second Samsung NVMe 2TB scratch M.2 disk, NVidia RTX Founders Edition GPU, ASUS ROG Strix z390 mobo with ASUS ac88pce Wifi Adapter on it, blue LED Corsair ML quiet fans all around in front to back, bottom to top airflow pattern. You can see the innards of my unit above. For this type of premium level of build, this Seasonic Prime Ultra Titanium 80+ 1k watt PSU is well worth it. I hope to enjoy my computer daily for the next 10+ years.

4. Well built, quiet, and a ton of accessories!

I picked up Seasonic Prime Titanium 1000w psu to replace a decade-old 1000W power supply that had a dying fan. The old PSU was only 80+ Gold rated as that was the highest certification level available at the time. I’ve used Seasonic power supplies exclusively for the past 10 years as their high-end hardware is always top notch.

The PSU comes well-packaged, so you don’t have to worries about any bumps or scrapes during shipping, even if Amazon fails to provide any functional level of insulation in their box. The PSU also comes with a myriad of internal power cables, including enough PCIe power cables to power a Beowulf supercluster. You’ll also get plenty of SATA and Molex power cables, and every cable is tightly braided to keep your PC clean and minimize interruptions to air flow.

If the fit and finish is anything to judge by, I’m sure this power supply will provide another decade of stellar service.

5. Best around

So 300-350 USD is a fair chunk of change for a power supply. Even in the 1k range this one is on the higher priced ones with the others hovering around 270-300. But this Seasonic Prime Titanium 1000w has one of the most consistently silent operating profiles you will every experience. Even under 50%-100% load, this PSU does not whine, does not hiss, does not complain at all. Even when the fan fully ramps up it is indistinguishable from background computer noises.

So if you have a case with poor noise performance, or a more open design, or want 1k power and the best silent operation under any load around, this is the PSU to buy.

6. Fantastic PSU

I got this Seasonic Prime Titanium 1000w PSU for my personal rig, since LTT keeps getting bought out by them.

Cons: It’s kinda pricey, but you know what?

Pros: It’s fully modular, there are a lot of extra cables for even the most insane builds, it’s highly efficient, and it has not once failed me.

I’ve had this power supply for a year now. The dust filter underneath it is completely clean. This is thanks to the hybrid mode only turning the fan on when necessary, like under a heavy load. Even with my Ryzen 9 3900X, X570 motherboard, three storage drives, and an RTX 2070 with enough RGB everywhere to make a unicorn jealous, my peak wattage was under 500W, so I don’t think the fan have ever turned on since installation. I don’t expect this power supply to die out on me until desktops can be incorporated into t-shirts or something. Seriously, if you want the last power supply you will ever use until desktops become obsolete, look no further.

7. Well thought design

While I have had the unit in operation for just a short time, it is performing very well. What I want to focus on in this review is the design of the unit.

First off being the footprint, I have a similar wattage power supply that I had intended to use in this PC build but it was too big in one of the dimensions to be able to fit in the case next to my radiator. This is what set me looking and I went right to Seasonic as they are in the top two of my power supply vendors. I was extremely pleased to find that this Seasonic Prime Titanium 1000w power supply is a good inch smaller than my other and fit the footprint bill well.

Add to that the fully modular cabling which makes it so much easier to work in the still-limited space remaining and that brings up the second focus of my review, the cabling that is included. The lengths and arrangement of the power connectors on the many included cables covered all of my needs from SATA to water pump to dual CPU connections. The installation was a happy one because of the design, and the performance so far (just a little over a week) has been what I expected from a top name, top of the line PSU.

I would also add that I was happy to find that the labeling of the connections and the external side were unlike the photos I had seen, and came out “right side up” with the fan mounted down as in a bottom mount with air intake from the filtered bottom of the case. That’s just a nice looking addition to the overall appearance of the system.

8. Efficient PSU with industry-leading warranty.

I ran a COUGAR GTX1050 almost constantly from 2011 until now. That PSU ended up going out with a bang and a flash. Just under 8 years of life. It was a solid enough power supply, had a decent lifespan, but only carried a 5 year warranty. I had no idea as to whether it took out my build or not. Regardless, I knew I would need a new PSU. I decided that I’d go for an even more efficient PSU this time around. That one was GOLD rated; so I figured I’d step up to the highest that exists now, TITANIUM. My current setup doesn’t require a huge power rating, but I figured that it doesn’t hurt to run a PSU at a lower wattage than it can handle. Plus, you’d have room for expansion. Beyond that, I wanted something that was quieter.

After hunting around for quite a while, I decided on the Seasonic Prime Titanium 1000w. The warranty that Seasonic has is industry leading. I thought about going with Corsair since I have some other components from them. I believe that the few additional features that those comparable PSUs had would just end up being additional points of failure.

This PSU was stocked by Amazon, and came quickly and safely. The unboxing experience was quite nice. The fit and finishing of the packaging and components themselves is quite above what I’d ever expect out of something that’s going to not exactly be in the limelight in your case. Plenty of cabling, which seems to be nice wiring with nicely molded connectors. All of the wiring that I won’t be using at this time will live in the velvety bag that Seasonic provided. Plenty of cable management straps included as well.

Once installed, my system booted right up. (So, I was pleased that the other PSU didn’t fry components as it went out.) My computer appears to be a bit quieter now. I believe that my storage drives are probably the loudest bit now. The Hybrid system will be nice. This allows the fan speed of the PSU to be ramped up/down according to thermal needs vs just 100% all the time.

So far, very pleased. I plan to hook up the computer to my kill-a-watt and see the power factor, etc. Hopefully I won’t ever need to use Seasonic’s warranty. If I did need it, I don’t feel that it’d be a hassle.

9. Perhaps one of the best Power Supplies I’ve seen

Can’t say enough good things about this power supply, quiet and energy efficient. I really could not be happier. Slipped right into my omenX case… no problems at all so far. Very high quality.

It weighs more than most other power supplies I’ve had which gives the impression of a really nice and well built piece of hardware. There are no cheap or plastic parts anywhere.

The thing that drew me to this Seasonic Prime Titanium 1000w psu was the fact that it’s like 93% efficient which is exactly what I needed since i plan on running this PC 24/7 so I wanted something that was friendly to the wallet.

10. Initial thoughts

Really great looking unit and feels quality. Rebuilding from a 5 year old rig and this Seasonic Prime Titanium 1000w psu got a lot of good praise. I won’t have it hooked up until some more components come in but first impressions are good. I tested the psu with the included tester tool (which is nice btw no need to do the paperclip method) and it seems pretty quiet. There is a low sort of ticking noise but I’m not sure it would be noticeable once in the case and other ambient sounds. Documentation in the manuals seems really scant, which also seems to be the norm these days.
