first of all ive been building systems for over 15 years so im not technically challenged (play on words much)....ok so...

i wanted a bigger power supply since i had money and was planning to upgrade my video card. i had an ocz gamexstream 600w that had alot of hours on it.

picked up a corsair HX750 for 2 bucks less than the hx620 ( special bulk buy apparently) so i was happy. also got an evga gtx 275 (nice).

the system was cleaned and things put back in place weeks before so everything was running fine.

so i hook up my new big ass psu. things are chugging along just fine. 15 mins later when im looking for a solution to the new video card display problem on my lg 246 ala hdmi, i inserted the evga disk that came with my card thinking maybe there was some funky new calibration tool i didnt know about........schlunk.( thats my word btw lol) the system goes off just as the dvd tray closed. hmmm.
plug the hx750 into my psu tester.....no juice. ok it happens. i'll take it back and exchange it.
so i plug in a smaller hx520 from another system......nothing. arg. mb is shot.
venture off next day get replacement psu (downgraded to the hx620 as i was afraid it may be a bad batch) and a new mb.
assemble and boot. np. it posted. hook up drives.....nothing detected. *&$%^. !!!
bitch to 3 retailers trying to find a decent hard drive and finally get one. pick up a new dvd burner. install and off we go to being a computer that runs again.

so this "new" fricking psu took out :

asus m2n32sli
wd 150gb raptor
sg 320
sb audigy 2 zs
pioneer 117d dvd burner

my only saving grace was that it didnt take out the new gtx 275.

the Corsair HX 750 is supposed to be a high-end psu. there should be safeties to prevent these things from happening. there should be overload/short protections that almost eleveate this sort of thing. i expect this to happen on some pos psu u pay 40 bucks for. not this.

i doubt its gonna get me any where but im sending info to corsair and anyone else whos interested. im told that they may do something.

sorry to ramble on and bitch and moan but i needed to get this off my chest.

was thinking of getting the 850tx, not sure I like what I'm reading from the op, whats the main difference between the hx and tx series from Corsair or are they just completely different?
 
They are both some of the best psu's out there. The OP just had bad luck. The hx is modular and the tx is not.

Internally, the HX and TX PSUs are completely different. However, both are pretty good. The HX line is Corsair's premium series, so those PSUs have excellent performance and are also modular. The TX line is their value series, so those PSUs have overall good performance, but are not modular, and are also a lot cheaper in general.

And don't let this story discourage you from getting a TX PSU. Even the best products occasionally have spectacular failures. The OP was just very unlucky in this case.
 
sorry i was so pissed i got the model wrong. its actually the modular HX versions not the cheaper tx.
 
I ordered the TX850. I don't think I need the modular. from what I gather the HX is based on newer design but I think I got a good deal on the TX, of course I'm kinda building my next system piece meal so it'll be a while.

The TX series is great, but the HX is a completely different breed of animal. Higher quality and modular. However, you made a good purchase. I have the 750TX and have nothing but good things to say about it.
 
online reviews say its a good psu but theres no time testing to see how long they last because they are pretty new so they just go by the specs and features. in asking around at local suppliers ive been told numerous times about diff problems with these newer (750 and 850)hx psus.apparently most just go dead and not blow the whole damn system up, which is what should have happend in my case.

first of all before now i would totally agree with you about the corsair name being high end for psus. the problem now apparently is the newer style hx (750/850) are not the same design as the lower wattage models. i just hope my new hx620 holds out as well as the other 2 hx520s i have had for years in other systems.
 
I've been happy with my Corsairs, tho they've all been Seasonic made units, and never had experience with the Channel Well ones. Tho people I've recommended stuff like the VX550/TX750/HX1000 haven't run into any trouble either.

I'm looking at the HX750 for my next build (i5, or i7 on LGA1156), tho that's a few months away still. I usually hold off on buying all new products to see if there are any "childhood diseases" to iron out first.

there really isnt any reason whatsoever that the psus safety mechanisms didnt work, other than shoddy workmanship or poor design. there should be no way you can overload the 12v line to the point of frying drives, there should be an internal cutoff.i just expect more from corsair.

unfortunately i didnt know these were relatively new to market. otherwise i wouldnt have bothered.

You got a defective unit. It's not bad design, just very bad luck.
 
That sucks. Talk to Corsair's service reps, they might be able to do something for you.

Had an ATI 4870 graphics card take out more /e-peen flex :D
 
Ive used a ton of those PSU's and had a 650 go out on me after about 6 months. It didn't wipe out any hardware along the way though. Got a fresh unit from Corsair and the guy who has my old rig isn't having any issues with it.

thats how i would expect a psu to go...
 
to be fair to corsair i wanted to update......

contacted corsair by phone today. after speaking to 2 people the tech support manager called me back this afternoon. said the psu needed to be tracked to have it looked at. i contacted my retailer who in turn tracked it back to their distributor. distributor info is to be given to the corsair tech support manager via my retailer ( i guess its a big secret....lol) so the psu can be looked at. so we will see where this goes...

This is good info.. so if a psu ever whipes out your stuff.. hang on to it!!! :)
 
update....sept. 4 2009

so between me corsair and my retailer we've tracked down the psu and its been flagged, supposedly on its way to corsair in california so they can have a look at it.....
 
Perhaps, like that Pepsi can down in Florida, it had a frog in it?
 
I had a similar experience with my PC Power & Cooling Silencer 750W PSU. The thing blew an evga 680i SLI motherboard, evga 780i SLI motherboard and 4 sticks of 2GB Corsair Dominator DDR2-1066 ram. To top it off PC Power & Cooling sent me a DOA replacement.
