Seasonic FOCUS Plus 650 Gold SSR-650FX 650W 80+ Gold ATX12V review

these are the higher end power supplies the gold efficiency performance that we're getting out of this 650 watt model that I have here as you can see fully modular which is the nice touch you know keep things neat and tidy inside of your case and you can see how things are labeled nicely so that you can't go wrong when you plug in the modular flat cables that it comes with we're gonna take a look at that in just a moment again solid good construction from C Sonic they've been around in the game for a long time and are leading the pack when it comes to

quality power supplies that hybrid button that you see there that's to turn off the fan should you be running this in a smaller machine you know maybe you're not running it with a lot of power you want to keep things quiet that fan is purring along very nicely no issues for me on that and again very nice touch that this is fully modular because that's what you need now a single 54 amp rail there on the 12 volt rail 648 watts as you can see how it's divided across the different rails and very strong because we want stable output here on idle to full load there are the specs 10 years warranty by the way on this beautiful I can't complain on that so they really stand behind their product and again the cabling itself terrific now let's look at what comes

inside the box obviously you get this package very nicely with some twist ties the cables some velcro straps very nice I'll be using those the manual and of course the little bag there with all the modular cables that you need now you're probably wondering what else well we've got the power cable as well because we need that now looking at the cable sizes and lengths how many here it is pause the screen if you're interested in knowing that here is a close look at each cable which is braided very nicely flat cables you can see they're tucked in neatly behind the motherboard tray I have it installed here ready to go and it looks terrific I mean look at that velcro strap holding it all nice and tidy there using the bare minimums just to get the system

going that's all you need and well what can I say I mean that's what you want right when you get a modular power supply you want it to be looking something like that here's a look at the back of the key of the case so you get an idea on how it looks and again that hybrid mode button should you decide to have the fan running on silent mode basically now here we go looking at the specs in the bias on idle those are the voltages that we're getting across the different rails stability is there because I also looked at it in Windows pretty much the same readings I'm getting as in the bias on idle but then I'll boost it up to full load now what I mean by full load is that I'll run the CPU doing some rendering the CPU will do the rendering then

I'll run the GPU in the background at the same time doing rendering so everything is being run at full load for maximum wattage and that way I can really get some good readings and you can see here that with these applications the wattage of the machine is going to go up in red at the bottom you can see those different wattages but at the top in green you can see there that we have stability the mid power range is great and it's giving us the boost that we need when we're running it full load and overclocked as well here are some more stability tests within three minutes these are the readings that I'm getting then I'll run it again six minutes these are the

readings that I'm getting after 6 minutes and then again after 10 minutes you can see that there's basically very little change variance in the readings that's a stable power supply and that's what we really want when it comes to overclocking and running things on full load terrific results from the focus plus here the 650 watt model I do have also the 850 model here they have a titanium and a platinum series we're gonna be reviewing that next

It’s not often you come across a power supply worth getting excited about, but this might be one. Howdy howdy guys , taking a look at the new Focus Plus series of power supplies from Seasonic. The specific model Seasonic sent me here is the Focus Plus Gold 850FX. First released just a few months ago in summer of 2017, Seasonic designed the Focus Plus series to be small, modular, and quiet. The Focus Plus Gold series all come with an 80+ Gold rating and the Focus Plus Platinum series, as you can probably guess, comes with an 80+ Platinum rating. Both series are available in 4 wattages: 550, 650, 750, and the highest,

850. Also, every Focus Plus power supply comes with a ridiculous 10 year warranty. That’s a long time. The box is actually one of the best designed component packages I’ve seen, it’s eye catching without being gaudy. Not that that affects performance, but shoutout to their designers on this. On the back of the box they have all the features and benefits of the Focus Plus series. They all use modern DC to DC converters for better stability and higher 12V output, promise tight voltage regulation within 3% of spec, are cooled by a 120mm fan with a fluid dynamic bearing for lower noise and longer life, and quite a bit more that I’ll cover later

in the review. More detailed specs, including the connectors, are listed on the side. This 850FX Gold comes with 2x 8-pin EPS cables for CPU power and 6x 8 or 6 pin PCIe cables; that’s enough to cover just about any build you could put together today. Inside the box, you’ll find the multilingual user manual – not much to say, pretty much “don’t open the power supply and don’t mess with the cables while it’s plugged in”, a bag with the mounting screws, some zip ties, and I really like this, some Velcro loops. These are a much better way of managing cables than zip ties, in my opinion, because you can adjust them so easily. There’s the wall cable, and then

the bag of modular cables. I’ll talk about those in a bit. Behind the foam, we have the power supply. It actually comes wrapped in a cloth cover – a nice touch to make sure it doesn’t get dusty or scratched while shipping. Also there’s a plastic protector on the logo, let’s peel that off. Perfect. One of the big draws to the Focus Plus is the super shallow depth, only 140mm end to end. That’ll be useful for people working in tighter cases. The modular jacks are all black and branding, unlike on some power supplies, isn’t over the top. In fact, one thing I really like is

that the electrical specifications are on top of the power supply rather than the side; it’s nice not having a big ugly chart facing out in your case. Although, this chart does have some nice numbers on it. Specifically, the 12V rail is rated for 70A or 840W. That’s almost the full 850W rating Seasonic gives it overall. On the back vent, other than the 3 prong connector and on/off switch, there’s a button labeled “Hybrid Mode”. This is used for switching between fan control schemes – one which keeps the fan at low RPM under light load, and another which completely stops the fan when the system is at idle. More on that in a bit. The modular cables are all completely black. The motherboard, CPU, and PCIe cables are all sleeved while the Molex and SATA cables are not. They seem to be about as stiff as typical cables, and not any thicker or

thinner. The 24 pin motherboard cable is 25.5 inches or 65cm long, the 8-pin EPS cables are 27 inches or 68cm long, and the PCIe cables are 28 inches long with a 5 inch extension to an extra plug (that’s 71cm and 13cm respectively). Onto peripheral connectors, the SATA cables are 33.5” or 85cm long and the Molex cables are 28.5” or 72cm. These should give enough length for most cases, and we’ll look at installation in a Cooler Master MasterBox Lite 3.1 microATX case now. With the shallow depth and fully modular design, it’s easy to drop the Focus Plus into a new or existing build without having to take anything out. The cables are easy to snap into the

power supply and have plenty of length to be routed behind a motherboard tray. Though the first section of cable sleeving is pretty stiff, they’re set far enough back from the plugs for it to be relatively easy to plug them in. Cable routing with a modular power supply is so much easier, especially in a case like this with relatively little space for cable management. The cable sleeves don’t get hooked on edges and the cables are flexible enough to twist them into an out-of-the-way position. That looks good. All in all it only took about 12 minutes to get this power supply installed and the results do look quite nice. Before I installed the power supply, however, I wanted to run some tests. Specifically, I looked at efficiency, sound level, and what kind of

noise profile the Focus Plus has. One of the big features that I was really looking forward to is Seasonic’s Hybrid Silent fan control. That’s a mouthful of marketing speak that basically means you can tell the Focus Plus to completely stop the fan under low load, when the power supply can stay cool just with passive airflow. Here’s their chart that gives the estimated fan curve – up to about 30% load, the fan doesn’t need to run at all. Up to 50% load, the fan can run at a nearly-silent fixed RPM. Above that, as the load starts getting bigger, the fan ramps up to maintain cooling. If you press the Hybrid Mode button in, this keeps the fan spinning even under low load. By pressing the button again so it’s in the “out” position, fanless mode is

enabled. To give a reference for efficiency and noise level, I’ll be comparing the Focus Plus to a Thermaltake Smart 500W, the original power supply I used in my Ryzen 3 build. The test setup today is my Little Red build with a Ryzen 3 1200 overclocked to 4.0GHz at 1.34V and an RX 480 4GB at stock speeds. Idle conditions were measured after the PC had been sitting at the desktop with no programs running for 15 minutes. Load conditions were measured with Prime95 stressing the CPU and Unigine’s Valley running on the RX 480. At idle, the Smart 500 drew 57.5W from the wall and the Seasonic Focus Plus drew 53.7W. That’s about 6% less power wasted. Ambient noise was measured at 48dB, though this is near the lower limit of my

reference mic. At idle, the Thermaltake power supply clocked in at 50dB while the Focus Plus was… Well, it was silent. The fan didn’t need to spin. By pressing the button and forcing the fan to maintain that minimum RPM, however, it came in at 49dB. Under load with Prime95 and Unigine’s Valley running, the Smart 500 drew 255W from the wall. The Focus Plus cut that by a pretty significant margin: only 237W at the wall. That’s almost 20W or 7% better efficiency. As for noise, the Smart 500 came in at 57dB while the Focus Plus was still able to stay in fanless mode; 48dB, same as ambient. Clicking the button to disable fanless mode, it stayed at the minimum RPM and clocked in at 49dB. Next we’ll listen to the actual recordings

so you can hear the difference. The only modification I made to these recordings is a 6dB boost on both so the sound is easier to hear, other than that they were recorded identically; same volume and same distance from the mic. First, here’s the Smart 500 at idle. Now here’s the Focus Plus at idle in fanless mode, and the Focus Plus in normal mode. Now at load, here’s the Smart 500. Next the Focus Plus at load in fanless mode. And finally, the Focus Plus at load in normal mode. As you can tell, the Focus Plus is ridiculously quiet, even before turning on the

fanless mode. Now for the pros and cons of the Seasonic Focus Plus. First, it’s extremely efficient; about 7% more efficient than a standard 80 Plus power supply. Second, I love the fanless mode. Quiet components are awesome. Third, every Focus Plus power supply is fully modular which makes cable management a vastly easier task. Finally, the Focus Plus series

comes with a 10 year warranty which is well above standard for the power supply industry. As for the cons, the ends of the cable sleeves are pretty inflexible so they’re hard to twist around tight corners. Fortunately Seasonic sets them far enough back from the plugs that you have a bit of bare cable to work with. Second, all these premium features come at a premium price; the Focus Plus Gold series and the Focus Plus Platinums . If you’re

thinking about building a mid to high end PC, Seasonic’s Focus Plus series is definitely worth a look. Or if you’re interested in silent computing , the fanless mode is amazing. In fact, I didn’t have enough power hungry hardware to get the 850FX’s fan to spin up at all in fanless mode. The only way I could get it to spin was by turning off fanless mode

altogether. Seasonic did a great job managing the thermals on these power supplies, while the low noise and high efficiency speak for themselves.

let's have sons it's blind ride with Cinematheque once again and today we're gonna have an overview of the see sonic focus gold 650 watt power supply so let's get to it the see sonic gold focus 650 watt power supply is 80 plus gold hence in the name there and we're gonna be doing mainly an overview just to see if it meets your needs on a very basic level if you're looking at more technical you know review of this I'll leave some links to trusted articles in the description below I just don't have the tools to really test that in-depth but what you're looking at is a power supply that's a hundred and forty millimeters wide a hundred and fifty millimeters long

and eighty-six millimeters high so do the measurements for the case that you're purchasing to make sure that it's gonna fit and fit your needs it is shorter so it's not a super long one or anything like that it should fit in pretty much any ATX case that you're looking at and even go down to some of the many IT X's and so on like I said that's just the information for you guys to go check for yourselves now it is fully modular and it supports four plugs on the rear for peripheral so we're talking about SATA or of course you know something like molex adapters on the rear there now I had the box as far as cabling goes in this particular matter it comes with

two SATA and two molex so just make sure that you order additional cable so if you're going to need them and then it has five CPU slash of PCIe shared plugs or ports on the rear for those two they are shared you can interchange them how you see fit now it actually only comes with one CPU additional power in the box as well as two PCIe plugs or cables in the box as well so if you're going to need to add additional cables make sure that you're aware of that for example if you have something like the X 399 taichi motherboard you're gonna have an additional CPU power so you're going to need to order an additional cable now that being said make sure that

you go to a PSU calculator and make sure that you're not using too much power in the case of adding on an additional CPU power and maybe a an SLI setup or something like that now that being said of course you're going to be able to get a lot of power out of this but it is best at its 50% load where it has 90% efficiency so in this case that would be 375 watts it load you would still have a 90% efficiency anything above that's going to knock it into that 80% efficiency

range that's really up to you I don't mind going over that however for peak performance obviously you're gonna want to keep it about 50% load now it does have a hybrid mode for the fan and this hybrid mode is essentially either you can have the fan running at all times or you can have it running only when it's at load if the button is depressed on the rear next to the plug

itself then that leaves the fan off at load and if the button is pressed in it turns the fan on at all times now speaking of the fan it should have a pretty good longevity as it is a hundred and twenty millimeter fluid dynamic bearing fan and that's just one of the better technologies for of course the bearings there you should be good to go even if you decide to run at all times with the button pressed in now why the unique things about this particular power supply on the interior design it is a cable free connection design to reduce human error so instead of having a board that receives all the modular plugs and then a human goes in there and solder the connections between the board and the and the rest of the power supply to you know supply

power to the devices you're plugging in this actually runs on connections on a PCB and is done you know without human interaction there and will obviously reduce costs for them and then passes on a more reliable product to us so pretty neat there and that pretty much covers everything about this power supply that you could need to know if you have any more questions about it please let me know in the comment section below and I'll try to answer it to the best of my ability
