Another failure

[LCADolby]

Before it was the gfx, and now the boot SSD died last night, a Corsair Neutron XT series... Only been in use since October 2015.
A complete fail only allowing access to the bios, even with SMART off..

I don't see a question in your post, so . . .  maybe this post will help?

What is the make and model power supply in that computer?

[LCADolby]

Corsair CX 750

Corsair products considered good, but my corsair ram experience taught me to stay away. They will replace the hardware np but its annoying as hell, with a boot drive arghhhh.

Can you fac reset it? I have a piece of software that allows me to facset my ssd's, from manufacture. Maybe a bios flash will do this, my drives do a destructive flash when bios updated........just thoughts.
Its not a port issue or bad cable........................ ...
That is a short life span.

Your SSD has something like a 25% failure rate within the first year. It's more money, but I have had excellent experience with the Mushkin Reactor.

Channel Well makes that power supply.  Not bad supplies, but they are mostly known for making adequate supplies to keep costs down.  The use of lower costs capacitors helps keep the cost down, but hurts the longevity of the supply.  Over time, they drift, but worse, the voltage regulation suffers and causes a lot of drift.

Not a power supply I would consider for use in my computers.  This one is pretty sloppy.  It may have contributed to the death of your components.

I don't know where you find information like that Skuzzy. I tried looking it up and come away with nothing.

That being the case Dolby you can't go wrong buying a Seasonic X750 Gold. I've had one out of 27 fail, and it was just age that caused that problem.

Over the years I have accumulated quite a bit of data on power supplies.   When Antec's power supply quality went downhill, they were using Channel Well for their supplier.  I got a lot of data during that period as we were using Antec, at the time.

Here is a recent review by HardOCP (http://www.hardocp.com/article/2015/01/21/corsair_cx750_750w_power_supply_review/1).  Goes into more detail.  I think it corroborates what I said.

 IIRC, it was you who pointed out my antec PSU might be the problem,and it sure was!  Saddly it cost me a MB,cpu and ram.

 I changed to an early corsair TX and it's been running my old desktop since 06!

I know Challenge, I tried before to try and find out which specific Corsair PSUs were of Seasonic origin and which weren't, without much success - obviously this isn't something they are advertising.  Skuzzy has been right though on the cases he's commented on regarding this.  It would be nice if there were an easy to access place to find out which exact models of various brands are Seasonic manufactured and just rebranded.  You would think with Seasonic's reputation that companies like Corsair would be happy to have that info out there, but perhaps they feel it would hurt sales of their non Seasonic made stuff too much...

Like in the closing notes of Skuzzy's link, I was one of those buying on the reputation of the name... I got it wrong in my initial build putting that in, I believed my components were sound choices 

[MADe]

I somehow think that having the knowledge and stats on something does not mean as much as we might think. For the most part, all my choices are still working as pc's. I only knew enough to match components, much less know about manufacturing  and such. I choose to over build for my use, using server grade hardwares for mere desktop usage. All tho they crapped out, I used to have all PC's on UPS's that cleaned/conditioned the power.

really like OCZ SSD. Kingston ram works great, makes me wonder about their SSD's. Not like all the different companies use different nand.....

[Chalenge]

Well, SSDs tend to be sensitive to electrostatics, but a failing power supply can take anything down. Probably the higher failure rate of the Neutron XT is caused by people choosing a PSU like the one Dolby chose. The Corsair RMx series of PSUs is made of much better stuff (the RM850X for instance). I would stick to the Seasonic PSUs myself, because there is no mystery as to who made them.

It's not always about the NAND. Design, controllers, and other considerations play into it also.

[Skuzzy]

Cheaper made power supplies lack fine regulation, for the most part.  An easy way to tell if you have a cheap power supply is to go into the BIOS of any recent motherboard, and look at the voltage monitor in the BIOS.

If the voltage levels are changing, at all (for any of the voltages), then you have a cheap power supply that will end up taking out sensitive components, or giving you grief in other ways (i.e. lockups, overheating, noise...).

Granted, that is not the only thing indicating a cheap supply, but it is the only metric most people will have direct access to.

As far as a quality 750W supply goes.  I recently had a Seasonic 750W supply on my bench, and it was an outstanding supply.  Rock solid and clean power.  Reasonably priced as well, I think.

If you do not have access to an oscilloscope, then I would suggest sticking with Seasonic power supplies.  They are always a known quantity.  Sure, you can get a bad one, but it is not a design issue which causes that.
