It's entirely silent no buzz or hum dead silent when paired with a SSD. It's effectively ventilated for a PSU, but nonetheless has marginal space for improvement in that regard.Ultra energy efficient from what I've read in critiques testing that location.It's modular and comes with some Velcro strips to help in cable management. It seems like it runs rather warm I think the cooling on it could be far better Seasonic must increase the all round Honeycomb Structure ventilation and possibly add a heat pipe or two in future designs to preserve points cooler running general. I believed it was load at 1st and was disappointed, but it turned out to be a old quantum fireball HD was creating a crazy amount of buzz/noise/hum even idle. I unplugged that and tried it with just a SSD and presto 100% dead silence.I then plugged in a newer 500GB Green WD SATA drive and it was about 97-99% silent when idling silent adequate.The old IDE drive was about 90-95% quiet/ boarder line silent around on par with a incredibly low RPM 14CM fan which by comparison to dead silent is irritatingly loud sounding.Needless the antique Quantum Fireball HD will have to be retired to a different technique probably a HTPC build for the living room due to the fact it's nonetheless a lot quiet sufficient for that objective.

SilentCoolEffective Value This issue expense a ton, and the packaging is out of this world as noted in other reviews. With that mentioned, I place this in a Lian Li Mini-ITX case and positioned it so the CPU fan blows through the PSU. The program runs cool ࿄-40c for the CPU), and the sound of the tough drives is the loudest point in the method. I would pay the cost once more and will purchase these issues from SeaSonic in the future. Exceptional product.

This PS, combined with a fanless CPU sink and fanless video card, makes my program definitely silent sparing an inaudible 180mm case fan and the HDD. Flawless so far. I have it operating an i5 750 system with an ASUS P7P55D Deluxe. It replaced an Antec EarthWatts 650 which I believed was quiet...and it was. But quiet and silent are two really distinct items my pal. Only the price...but the silence quickly makes you view it significantly less as an expenditure and additional as an investment in your sanity. If you can afford it, absolutely go fo it. A 财 energy supply isn't for everybody, and even sounds a little koo-koo at initial. But it really should be at the best of your birthday or Christmas want list.

It is silent, no eletronic hum or chirping. I was pleased with the top quality. Cost. The cables are pretty stiff. I didn't mind, but it created routing the cables a bit of a chore.I've in no way had a PSU really fail (in my residence PCs), typically just the bearings in the fans fail and I end up replacing the psu rather of just the fan... Hopefully this is the final PSU I have to obtain and that would make up for the price tag down the road.

No sound, very tiny heat. Unit is cool to the touch soon after many hours of laptop usage. I thought my program would not strain the unit, but was shocked to locate it not even warm. Fanless cost premium Even though I'm particularly impressed with this unit, I'm not good I'd go the fanless route again.

What a great product. You actually don't want to be concerned about this point overheating. The efficiency is ridiculous. I have this inside of my somewhat compact HTPC case, inside a cabinet with really low airflow. The left rear quarter of the Pc gets a bit warm to the touch, but never ever gets as well hot with restricted airflow. Really impressed. The packaging is impressive, but I would have rather spent บ significantly less and not gotten a velvet bag to retailer the modular cables in, or a velcro bag for that matter as well. Overall great solution. You can't get any quieter than this silent power provide. Plus it's got best numbers to get the 80gold certification!

Outstanding make top quality. Outstanding power quality per the reviews on it. Runs really cool in my low demand system. 1) The CPU power cable is too short. It reaches OK, passes by way of a hanger on the top of my case, and goes around the corner of the MB, but from there its nearly straight down to the connector. It demands another 8" in order to fully tuck it out of the way. 2) The unit is a few millimeters as well tall for the expectations of my case. It conflicted with a locating lip on the back of the case and the tool-significantly less mounting strap would not perform due to the fact it was a little also tall. I didn't thoughts the mounting concerns, I was modding my case a small anyway (Lian Li Pc-B10). My case produces good air stress and I can really feel a cool breeze coming out the back of the PSU. Worth the dollars if you can afford it.

Keeps the space inside my case free of charge of clutter. It's cool, efficient and quiet. Anything I need to have in my case.

Wow!! Ultimately a definitely fanless energy supply ever constructed, and it's hard to match each in good quality and value in contrast to other individuals. Definitely none! I very propose it to everyone who desires a super quiet and efficiency energy provide.

Stays really cool. Well built. The cables are plenty long sufficient. Cables are quite stiff. I had a hard time connecting the power cables to the back of the power supply because they would hit the bottom of the five.25" drive bay enclosure. I was surprised at how cool this power supply is even when beneath load. I anxiety tested the technique for hours and the item was barely warm to the touch.

Anything. Dead silent, barely warm soon after many hours of uptime, very very good-looking, and uncomplicated to set up/configure. Cables are indeed a bit stiff, as an additional reviewer has stated.

totally modular, no lines are forced on the user by the manufacturer, did not advertise overrated wattage, did not skimp on components (I was unlucky and was missing one of the minor cables which they promptly replaced for me at no added expense) Only sensible 400w PSU I could find with 5yr warranty on the market at time of buy. The added 4 pins on the major motherboard connectorྴpin Ʋpin) is near impossible to separate and even when separated the unbound potion of the cable is too brief and inflexible for the 4pin to be put out of the way (constantly pushing against a capacitor next to the connection on my mother board). Similarly the additional 4 pins on the cpu connector Ɣpin Ʋpin) was not versatile/long sufficient to be tucked out of the way so as to not touch the motherboard. Location of the energy cord interface is not excellent, incorrect side on my situation unless I flip the psu upsidedown, which the manual especially says not to do. So I guess this unit was created for bottom mount case or leading mount with open best (btw, I by no means understood the logic of open top situations, seems like an opening for debris to enter the computer and unnecessary threat from spilled coffee to land on psu and fry the laptop or computer, yes, my coworker has accidentally spilled their drink ahead of and it overflowed sufficient to drip onto both computer systems) psu’s interface with modular cables only permits you to connect 3 of the 4 SATA/molex cables (not that you must need to have all four). The two floppy connections is optional at the expense of a single of the five molex connection(most folks will not will need these anyways). No switch amongst 115v and 230v(most men and women don’t need it anyway unless you program on taking your personal computer via TSA to Europe, the switch normally just adds confusion to inexperienced purchasers anyways)The line with the 2 molex connectors and the line with the 2 SATA connectors were barely extended enough for the longest connection to reach the closest item in my situation so the shorter connection on those lines might be useless in a lot of cases. The other lines had plenty of give to reach their targets. Warm to touch but cooler than other PSUsI’ve encountered DOA PSUs from reliable businesses like antec and corsair but none so far from seasonic. Athena lasted ten years and still workingAntec, Thermaltake, Rosewill all nonetheless functioning immediately after

Quiet, efficient. Expensive, but worth it if it's as reliable as it is efficient. Only five SATA connectors on two cables: 1x3 and 1x2. I'd gladly trade the velvet bag for 2x3. I'd even gladly spend additional for one more 1x3 cable, if they had been made readily available. I have it mounted in the "traditional" position, which is upside down relative to the encouraged mounting. There just isn't enough space above the power provide in my case to mount it the advised way. Temperatures appears to be fine at light loading (idle 25%, total load 40% of rated) and with some outdoors air getting pulled by the unit into the case.

Totally silent and extremely cool in operation. This Is a good PSU for a HTPC. High cost. I wish SeaSonic would make a fanless 200, 250 and/or 300 watt model for low power HTPC and SFF builds.

Runs silent and cool in my setup. I am utilizing it to power a By means of C7 ITX board and a few drives in my DIY NAS. Although I was searching for something with much less wattage (for superior efficiency), the PSU runs super cool for my application.The modular cables had been also a extremely nice touch as my case is now super organized.Speaking of, SeaSonic included some Velcro cable wraps and zip-ties which I thought was seriously cool of them. It is on the high-priced side. I would really suggest this in instances where audible noise is an issue (such as a recording studio, HPS, NAS, and so on.). For a typical Pc, obtaining a PSU fan could not be as significantly of an problem. SeaSonic appears to make PSU with fans as nicely though I have not tried them. My final bought PSU was a Pc Power and Cooling and I would suggest them as nicely. It comes in some fancy packaging that produced it entertaining to open the box. I'm not sure the packaging is worth the cost (I don't actually need a fancy bag for my PSU soon after it's installed) but it was a good touch.

Runs incredibly cool... quite little detectable heat at 70% load. SILENT (but I guess you already knew that :). This 80 PLUS Gold PSU has dropped my rig's low power consumption down one more 15-30W (depending on load). Isn't wired for two x 6-pin PCI-E; at the moment operating my Radeon HD 4870 employing the offered PCI-E and a SATA cable. Minor quibble, and mostly mainly because I didn't read the fine print. Price could be a deal-breaker for some, but I have no complaints. Running on a MYOPENPC DOMA test bench, so it gets fairly very good ventilation from ambient air movement.

Runs amazingly cool (Like, surprisingly cooler than any other PSU we've worked with)A lot of power with plenty of cables to assistance it.Awesome modular cable management which, in our situation, was very crucial.General, best PSU that actually surprised us. Expense - Was 财 at the time we bought it so it wasn't low cost but it was worth it. We necessary an energy efficient, modular power supply that was silent, and boy does this guy deliver. We we're skeptical about utilizing a Seasonic simply because we haven't heard the name considerably in the sector. If your worried about the very same issue, don't. This is most likely one of the most solid, stable and nicely built PSU's I have ever worked on.

Impressive and stable power supply. Following I read the evaluations from couple of assessment internet websites, I decided to purchase X 400FL for my HTPC. I like the modular design and of course, no noise. None so far. It would be excellent if Seasonic created greater wattage fanless power supplies.

properly created, quiet, very effective, underrated output. overdone packaging, documentation is lacking, support response was poor. They give you a bunch of decals and stickers, but no illustrations and won't talk to you when you need help. PATHETIC.Read a evaluation that said they actually got 600W out of one these w/o it getting hot! WOW!My challenge was with that 20Ʋ m/b connector. Yet another reviewer stated impossible to get apart; I felt impossible to figure out! I had never seen a connector like that - it snaps on 1 side and pivots on the other. I sent a support email asking how to get it apart and he just sends photo which doesn't answer my question, so I ask again and get one more picture. UGH!!! Not a single word in the response emails! Phoned support and asked for a callback, but got nothing. Luckily, I looked at it lengthy enough and kept thinking about it and it came to me. BUT..... it would be SO Easy for them to put in a single sheet of paper with some figures on it. The manual is all verbal and covers about 8 languages.
