Product Description
SeaSonic X-850 850W 80 Plus Gold ATX12V / EPS12V Power Supply. False Anti-surge Shutdown Issue: The built-in anti-surge feature on some motherboards is known to produce false-positive readings while monitoring the output voltages of the power supply. Seasonic power supplies have their own integral safety features to protect all the components against electrical damage. When your system shuts down due to this problem in the motherboard, please follow these steps: 1. Update the BIOS of your motherboard to the latest version available. 2.Check the power supply’s output readings in the BIOS. 3.If all seems to be normal then turn OFF your motherboard’s anti-surge protection. 4.To make sure that everything runs properly, you can check your benchmark scores (Futuremark, OCCT, etc.)

The point of the story being, his Non Seasonic power supply was approximately 4 years old when it died past it's warranty, and my dead corsair also lasted a little past it's 3 year warranty. As for Seasonic, since 2002, I've owned a few of their units. None has come to mind that has failed on me yet. I've also given away an old 620W 80plus model I've purchased in 2006 that's still kicking to this day confined in a desk cubby with inadequate air flow.
I can babble on for hours about how great this unit is on efficiency, how quiet it is, build quality, rail quality, customer service, etc.
But here's what it boils down to:
"How reliable is this unit?" Very reliable. "What happens if this fails?" Contact Seasonic, they'll ship you a replacement unit. Also this won't kill motherboards and components like the Bestec power supplies did. (Look that one up guys)
"Why buy this when I can buy 100000W brand XYZ power supply for half as much?" When you spend $300+ for a CPU, $400 for a GPU, $150 for a case, you can budget some money in a quality power supply that will easily outlast your video card in terms of functional use. Go ahead, save some money, buy a cheap crap PSU, but don't cry when your expensive part fails.

The gold rated efficiency claim I tend to view more as marketing since psu mfg's police themselves, besides, efficiency ratings only matter for over 80% utilization. I don't expect to be taxing the psu that hard all the time (the one 2star review, I don't think 850w is enough for his kit). For me, the quality of the power is what counts. I use a psu tester always before plugging it onto my mb. This unit was solid spot on for all voltages except one plug was 11.9v. Within spec, but there's enough connectors that I can not use that and have plenty to spare. If I add so much hardware I'm actually using all the connections on the psu, I should be buying a bigger psu.
It's very quiet. I have mine on normal mode, I don't see a need to go to fanless mode.
It's fully modular and comes with a nice sleeved mb power cable, and plenty of black power cords for most anyone. The mb and cpu power cables are long enough to route through a thermaltake A71 full tower with slack to spare connected to a ASUS maximusVI hero full size atx board. Quality of power, ease of installation, and number of connectors are all excellent.
A bonus is the bags for the cables that it comes with, and the bag the psu is packaged in. Rather than a rats nest of unused cables, you can keep your spare parts organized, the velvet bag will be stuffed with extra cables in my parts box.
The only con would be, for me, is that it is a single rail psu. Single rail psu's mean you don't have to balance the load on the psu, but I'm used to that. Since most psu's now are all single rail, I'll have to grin and bear it.
I've been around the block the last 20 years building and supporting machines for a living, electronics fail, fact of life. In my experience though, if it passes burn in, I expect this unit to be as rock solid as any seasonic psu. It's smaller, lighter, made in china, but what isn't nowadays. The one good thing is that seasonics have always been made in china, so I'm pretty confident they know how to make a power supply. Any unexpected failures down the road and I'll update this, but if I need another power supply for another build, I'll be buying a seasonic again.

Silenziozissima anche con la ventola su normal , hybrid si sente appena.
Discovering the Seasonic X-850 was nothing short of a revelation. It comes in a box that looks as if it's going to contain the crown jewels. I've never seen electronics packed lovingly in a velvet draw string bag before, and it looks like it comes from Tiffany's. All the cables are laid out in a pair of neat nylon pouches and unfold like Dexter's toolkit. And there is a cable for *everything* you will need - and they're of decent length (unlike my ex-power-supply's, which fought to get to the ATX connectors in my Thermaltake Level 10 GT case).
The instructions are a bit basic and read like the taglines from a marketing brief, but it's not hard to fit -it can only go in one place, and one orientation. Slapping everything back together, I powered up. And lo and behold... Everything was immediately fixed, even things I hadn't associated with power - no more strange instability, no more spontaneous warm-boots, and my last two drives are straight in and working a treat. Immediately I noticed that the strange screen shimmer I'd been noticing had gone too (thanks very much, old PSU) and the fans that I had thought were just well designed to be silent roared up to their max speed - embarressingly, they had actually just been undervolt. Mister Multimeter shows 12.08V on idle, 12.17V on full load - and most amazing of all, the 5V bus is a rock - 5.05V at any point in the duty cycle. Now that's good regulation.
I admire good engineering and this piece of equipment deserves all the praise heaped upon it. It's not cheap - at £180 it was getting on 7 times the price of my stock supply - but in terms of quality, reliability, stability, and sheer avoidance of wasted time and energy, it's a total win-win for me.
Bearing in mind most system builders keep their cases through 3-4 motherboard iterations at least, it's a long term investment that can only be a wise choice for years to come. Get one, then forget it even exists - the ultimate accolade for any technology that just quietly does a good job.
Que se soit en charge ou non celle ci reste inaudible,teste effectuer avec OCCT pendant 1 heure ,seul la carte graphique reste audible car avec se genre de test qui est fait pour monter en puissance,normale que le ventilateur tourne plus vite.
Je recommande cette alimentation , malgré un tarif un peu trop élever,vue la qualité,le prix est vite oublier,de plus j'avais un bon offert de 15€ pour l'achat de l'alimentation.
Seul problème au sujet du bon d'achat j'ai envoyer les documents demander pour preuve ,j'ai reçu un mail comme quoi j'allais recevoir le bon,mais jusqu'à maintenant j'ai toujours pas le bon d'achat de 15€.
Edit: Je viens de recevoir les chèques cadeaux,mais je ne pourrais pas les utilisés sur Amazon ,dommage.
