So seasonic saved me from a fire, or did it?

Been trying to test this new 290x with mining, random restarts, computer hangs, card isn't OC'd

While troubleshooting all the things that could be wrong I decided to replug the connectors in my PSU

This seasonic x 750 has been good to me for 1.5years

While removing the pci-e for the ONLY 290x in my rig I notice the connector is MELTED.

MELTED. I couldn't even remove it, so when I did, obviously the black pieces on the connector broke off.

I'm going to RMA this thing but, no single rail was completely overloaded, this is a gold rated 750 watt power supply and I'm not even close to reaching that limit.

So RMA or not, did I have a unlucky psu? What could have possibly gone wrong

I am assuming the short is what kept causing the PC to restart, but to be honest it was more of a screen goes black, everything is still powered on(gpu fans spinning , cpu fan spinning) ? I still don't know if this was the main reason for that or not, still have to test bunch of different things

Here's some bad quality pics for you to see

this is the 2nd Seasonic PSU that I have seen do this in less than a week. See this thread.

What it looks like to me is that seasonic has a +12 and a negative crossed. because the PSU should not cause this it should be a short on the other end. and you see it here because this is where the heat would start first, or maybe the ribbon cables they are using is allowing a short.

Good luck Hulk.. interesting to see what happens because I know seasonic is going to blame it on what ever you had it hooked to. Unless they know they might be a problem then they will replace asap to keep you quiet....

that is also a possibility but it looked like the connector was tight to me in the pictures but might be bad pins not making good contact causing this also... I have removed the factory pins from psu connectors and found some that was not stripped out and had been crimped to insulation....

Thanks man, I really hope not.
I would be quite aggravated with seasonic. Everything on my PC is fine except this destroyed cable that was melted into the PSU.

Really sucks that happened to RAFFY, much coincidence happened on a 290x eh. Guess tomorrow will be one of those fun days.

Slack on the cable?
There is no loose connection I plugged the connector into where it goes making sure that it clicks in place.
I used this power supply for 1.5 years and after putting in a 290x this happens? Sucks for me

problem might be with the 290'x also pins hooked up wrong or something like this. If you guys have problems need to get together so you can prove it not just one time happening. let us know how it turns out!!

Customer service is a big thing to me. I will pay more for good service and have in the past and will continue to...

It has to be a problem with these power supplies and the 290x. Mine was hooked undervolted, and the psu was running at 80% capacity at most. So far Seasonic has been great. They paid for return shipping and are willing to reimburse for damage to my computer case once I send them pictures. So far they have been great.

I just hope they are the same with me, thank you for sharing me the experience.

I'm honestly afraid to get the Seasonic X 1250 now and am considering a Corsair 1200i with the single 12v rail.

I've never been more glad to not finish the sleeving job. I'm sure all the paracord bunched up might of had a different effect if 10 wires burnt up at once. A sleeved pci-e cable could of ended up costing me my home

Get a EVGA SuperNova G2 Instead

That is great and I am glad to see good customer service.. but I wonder if this is because they know they have a problem and have not announced it or they are just that good at customer service. Time will tell but glad to see a company stand behind their products!!!

The same question I had in mind.

I read some newegg reviews on the Seasonic X 1250. I thought to myself, should I really buy another seasonic? I mean, they are good PSU and I was unfortunate but I don't know the actual cause of the problem.

Further reading some good/bad/silly reviews I noticed some claims of Seasonic advertising a 100+ amp 12v rail when it is 4 rail design
http://www.overclock.net/t/1215732/seasonic-x-1250-vs-corsair-ax1200/10

This thread and dozens of reviews are forcing me to never buy a seasonic again.

Sure many of these PSU are rebrand the problem is even for example Corsair, I was reading about the CX models on this forum a week ago, not sure exact problem but it seems every manufacturer and every oem psu or rebrand they use will range from good psu to bad. Example, thermaltake, TR series is terrible while the Tough Power is pretty decent.

I need to figure out what will be my best bet for a power supply to handle 3 290x, a OC haswell, and everything else connected in the rig, 20 fans, drives, waterpump... The whole shabang

Some of the TR-2´s are bad thats the HEC models

The TR-2 model made by CWT and FSP are decent

Again get a EVGA SuperNova G2

If there is any information you can give me that will help me research this PSU I will consider it. You might know something reviews don't cover and save me time and money.

I'm looking at the Corsair AX1200i but if you can fill me in on why you have mentioned the EVGA supernova twice I will appreciate it

That single 12v rail on the ax1200i gets my eye seeing I'm going to be putting 3 290x on the rig and at max load I don't want to be stressing multiple rail designs like this x750 I had, I really can't learn from first hand experience anymore, going to have to dig the internet and hope the unit is as good as they say

EVGA SuperNova G2 is based on the Super Flower Leadex gold rated

And the EVGA SuperNova P2 is based on the platinum version of the Leadex

I know it is hard when you have had a bad experience with a company but overall I really thing seasonic makes some of the best and most dependable PSU's not only for the money but overall. They actually make most of theirs and most companies their best PSU's are re-branded seasonics.

personally I am watching for more of these and also how the RMA's play out. to me that is very important. Like I said before I can understand your feelings on seasonic now but I think you should give them a chance to make it right because problem might actually be with the 290's... I still can not figure out or see how the PSU could cause this unless it is manufacturing quality control problems like pins not solder or crimped correctly or a isolation problem...

Compared to how many units are out there and how few units have problems i would say the amount of bad units are so tiny its almost unheard of

You are trying to help and this is going to sound really bad...

So I clicked that best fully modular thread and it's like Corsair AX models are "lower is better" on more than 75% vs Supernova, why are you recommending supernova again?

You told me to get a supernova
You link me a comparison thread
The thread shows the Corsair AX better than a Supernova in 75% of the charts

Thats the AXi models which are a ripoff

They might be a tiny bit better but they also cost at buttload more money

The AXi models are a ripoff you can get almost as good or better in some areas for far less money

240$
http://www.newegg.com/Product/Product.aspx?Item=N82E16817438011

399$ and on sale 330
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139039

Thats 90$ to 160$ more for a unit that is less then 1% better = massive ripoff

And the G2 has 100 watts more

Ripoff or not I want to pay for the best performer. Does the single rail on the corsair ax1200i DEFINITELY handle multiple cards at max power better than a multiple rail design of other psu (like seasonic x1250) ? I noticed the supernova is single rail too which is nice

Also, is the platinum vs gold efficiency neglected? I know you mentioned the supernova designs are from the platinum version?

Trust me I'd rather save money, but if it's going to cost me 3 $600 cards a few months down the road, or even my home when I'm gone, I will spend the extra money

Looked into it what you saw in that thread was THE 1000 WATTS versions

The SuperNova G2 1300 watts has better voltage regulation then the AX1200i but ripple is within 2-3mv of each other so i call that a draw

The G2 has less then 2% lower efficiency then the AX1200i and more like 1%

I say the G2 with its better voltage regulation and much lower price is the better value of the two by far
