Seasonic FOCUS Plus 750 Platinum, 80+ Platinum Certified 750W Full Modular Power Supply with 120mm FDB Fan

This is the power supply you've been wanting your whole life, but never knew you wanted until you installed it in your system.This Seasonic power supply came with a test device which works very simply: hook the main power cable up to the power supply, and plug in the motherboard power cable into the corresponding port on the power supply. Next, take the plastic test device, and connect it to the end you'd normally connect to the motherboard. Turn the PSU on, and see if the fan comes on. If it does, you're good.This PSU is so quiet, that with my head right next to it, I thought it didn't come on. The fan is dead silent. I had to look at it to verify that it was, indeed, turning. This is a stark contrast to any other PSU I've ever used, which sounds like a small jet engine is about to take off in the room whenever I turn on the computer. My new build is so quiet that the fan from one of my external hard drive cases is louder than the entire computer. That's impressive. I think I've made the point: this thing is quiet.It's also entirely modular, and delivers clean, consistent power to all of my components. The cables are nice and easy to snake to their appropriate locations, and they're clearly labeled (if you're a new builder, or if it's been a while since you've built a PC, this is a nice touch. The "gold standard" for testing power supplies is the PSU Cultist list. If you look at the list, this PSU is top-rated, representing an elite class of the best power supplies on the market. I paid a bit more for this, but I figured with all the other cash I'd spent on my new build, and extra $40 to be sure my power supply was excellent was money well-spent. It's next to nothing over the life of this computer.All said, my recommendation is to not skimp out on a PSU. Total up the maximum wattage your system is expected to use, then multiply that value by 1.5. The resulting value tells you what your PSU wattage should be, give or take a bit. You don't need to get a 1000W PSU "just because". Right-size your PSU to your build.Now that I've put a Seasonic power supply in my latest build, I'm never buying another brand. It's that good, and the hype is 100% real and justifiable.

Seasonic is the company that actually makes the PSUs for a lot of the "big name" brands you might have heard of, but PC enthusiasts know to go to the source and just buy their products directly. The Focus Plus 750 Platinum is very highly reviewed (Tomshardware.com, Jonnyguru.com, etc.).This unit has great specs that most people don't even look at: low ripple and noise, good transient response, and great voltage regulation, and lots of circuit/ unit protection features. Plus it's quite compact and fully modular. The button on the back lets you toggle a "fanless mode" that turns the fan off when the unit isn't working hard. The build quality is excellent. The cables are all black and sleeved except for the SATA and MOLEX, which aren't sleeved.Installing it was easy since it's a somewhat compact unit and fully modular. The cables are labeled well and of a good length. The overall impression is that it's a great unit, which I already knew it would be from the reviews it got.The PSU market is quite crowded, but this unit caught my eye because of the low ripple, great voltage regulation, great efficiency, decent price, and that Seasonic is an OEM for many other computer brands.The only negative I have to say is that the cables are a bit thick and stiff near the connectors because they put capacitors in the cables (although this is done to suppress ripple and noise) - maybe in a future revision they could just put those extra capacitors in the actual chassis.Not much else to say about other than to check out the reviews at Tomshardware, JonnyGuru, and HardOCP and other places (SSR-750PX is the model I got).Don't skimp on a PSU, if it doesn't destroy your computer, high ripple and poor voltage regulation will wear your other components down faster than with cleaner power.Plus it has a long, 10 year warranty.

The first thing that was really important to me and which this PSU does well is having a fully modular setup. This allows me to install just the power cables I need which saves space in the covered PSU area. Everything came nicely packaged in protective bags and the finish is outstanding. The 10 year warranty is the best I have seen and it has great features like everything being setup on a single 12V rail and a hybrid mode which you can select via a convenient button on the rear of the supply. In the hybrid mode when the PSU is under a low load the fan does not spin as fan cooling is not really required. This saves on both noise and fan life. Even when the fan does come on, it's one of the quietest I have ever heard.. or not heard more precisely! All in all this is a great Power Supply and easy to recommend if you are in the market!

So far so good. I will update this review from time to time as the PSU ages. This replaced a 6+ year old Seasonic that was rebranded under the Corsair name as the 750TX V2 model. It was a decent PSU for its price at the time, but the last storm killed it. The thing was very dusty inside as well, and it definitely needed to be replaced after a lot of work overload in the past 6 years.This is literally the best 750w PSU out there for under a hundred bucks. Platinum certification to boot. My last one was just Bronze. This is a beastly PSU no doubt about it. It's also modular, which is the norm now but was not when I got my last one! What a nice feature compared to the ridiculously tangled 750TX.All of the specs are better in every regard compared to that one. This is an incredibly nice platform for under 100 dollars. The fact they made Platinum at this price point is impressive, and it is clear Seasonic has mastered the PSU business. It looks nice, it is made with quality parts that you can verify in numerous in-depth reviews online, and as an overall package it is nearly unbeatable in its class.There isn't too much more to say. The cables were adequate and well made. The ripple is low, the power is there, and once again Seasonic has a top-tier PSU on the market for a fair price.
