Seasonic FOCUS Plus 1000W Power Supply

The aforementioned FOCUS Plus 1000W full modular power supply belongs to the renowned FOCUS series of Seasonic. It is an 80 Plus Gold standard power supply with decent fan control.

Because the Seasonic cables and distinct wires are not color-coded, it takes some time for a multimeter to validate that the plugs were the same and both conveyed Ground and +12V. Moreover, the unused plug was tied to the cable at the back to guarantee that it cannot touch any component of the motherboard. Everything stays tidy and firm with the extra cable tie self-adhesive bases.

Top 9 Seasonic Focus Plus 1000W Power Supply Reviews

1. Excellent quality, quiet and powerful

I purchased this Seasonic Focus Plus 1000W to build my new gaming system, which will be very demanding as far as power (2x SLI Nvidia RTX 2080ti cards, Intel Core i9 9900k, Gigabyte Aorus z390 Master MB, 9 Thermaltake Riing Trio RGB fans, NZXT X72 Kraken CPU water cooling system). The packaging is more than adequate. In fact, probably overkill. Not only is the PSU surounded by a foam box insert, it’s also encased in a fabric bag. The cables are also packaged in a drawstring fabric bag. The unit is clearly high quality and has exceeded expectations as far as power output and efficiency.

2. Very compact unit for 1000W PSU

The Seasonic Focus Plus 1000W is very quite even when I run load on the system. I am not running a crazy load or something like that, but I think 1000W PSU is plenty for most med to high end system. What bother me the most is the cables, they come sleeved but the 24-pin cable to be specific is very big for my cable room behind MB tray. What interest me when I open it up that it come with 24-pin jumper in the box as long as free 25$ steam card.

3. It’s a power supply.

This is my first fully modular power supply, and I gotta save I love it. It’s by Seasonic, so you know it uses high quality capacitors. It’s 1,000 Watt so you know it’s COMPLETELY overkill for 90% of builds. It’s Gold proof, and the jump from Gold to Platinum isn’t worth the price difference in my opinion. It’s average weight for a power supply. The packaging it came in was high quality. The cables are beautiful compared to other “out of the box” cables. I’m not sure how this is the “cheap” Seasonic series when it’s so good. Only thing I don’t like about it: Gold accents. My build is black and RGB, and having a static gold accent in my case is a bit annoying, but it’s hardly noticeable to the untrained eye. Also, the top circular grate looks a bit cheap compared to other seasonic power supplies that use a more blended look.

4. stiff cables, but great quality

I’ve always wanted a seasonic power supply, especially since i read that they do manufacture their own units, unlike most other brands, so i trust seasonic a lot more than other brands because they stand by what they create, plus the 10 year warranty is amazing.

Now that i have one of these nice power supplies though, i can say for sure that the quality is really awesome, it feels well-made, the cables arent ugly, and knowing i have a seasonic unit makes me feel more confident to overclock further.

Only downside i can think of was that the cables were stiff, and i used the three of the 6+2 pin cables in my case which ended up being a little bit of a tight fit.

5. This is the best PSU I ever come acorss in my life!

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 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.

6. Definitely recommend this for noise sensitive people.

I replaced an old PSU just for safety when I upgraded my gaming computer. Ryzen 5 1600X, Nvidia GeoForce 1070ti. 2 Water pumps for liquid cooling.

This Seasonic Focus Plus 1000W PSU is quiet, and the fan has a sliding scale of noise. My old corsair PSU was either on low or max speed which was very annoying. This fan is 100% silent until it actually needs cooling, and the fan only spins as fast as it needs to. Definitely recommend this for noise sensitive people.

7. Great PSU for the money.

I purchased this Seasonic Focus Plus 1000W PSU, because it was GOLD rated, and affordable. I have an older 620W Seasonic PSU that is still running strong 15 years after I purchased it. This PSU is rated very well, and I expect nothing less from Seasonic, they have been making PSUs for a very long time, and even make them for many OEMs, and other companies out there. This is a great PSU for the money, and actually smaller and quieter that that 650watt PSU it replaced.

8. Good Quite & Affordable PSU.

The PSU is great price point for being modular and high reviews. The only thing I disliked was the $25 free steam e gift card that was NOT available when I tried product registration. Shouldn’t include an offer if you’re not going to back it up. Other than that the product is good.

9. Small and dead silent

2020 July update: Still running silent and strong. Absolutely recommended.

Original review: I bought the Seasonic focus Plus 1000 gold from eBay, semi-new. According to Seasonic’s website, the warranty should be transferred as long as you have the original purchase receipt. It’s amazing how much less noise it makes when compared to my previous EVGA Bronze 600w semi modular PSU. It doesn’t get hot while running a ryzen 5 2600x + 64gb ddr4 3200 MHz + EVGA 2080 ti xc ultra ( I understand the load is very small compared to the power capabilities of the PSU – still great, though!), I mostly bought it to guarantee I’d be able to run the 16-core 3950x ryzen and two titan rtx in the future. I’ll update the review again in 1 year.
