PSU blew up after installing new GPU

[xtre]

Recently bought XFX ATI Radeon HD6950 2GB. After finding out that I needed another 6 pin from the PSU I went and got an adapter with female and male molex connections to 1 6 pin. I connected up both molex from different wires started up my pc and played max pain for a while on max to test it out. After about 10 mins of playing it got quite hot and before I could do anything about it it popped twice really loudly and cut out. I examined everything and found that the PSU had blown just from the smell it gave off. I'm yet to test if anything else is damaged with a new PSU.

What could have gone wrong?

PSU: 700w
GPU: XFX ATI Radeon HD6950 2GB
CPU: AMD FX 8150 (8 x 3.6 GHZ)
Motherboard: Gigabyte GA-990FXA-UD5 (AMD 990FX)
RAM: Corsair 4GB XMS3 PC3-12800 1600MHz (2x4GB)
CPU cooling: XIGMATEK GAIA Heatsink & Fan

Oh nooooo :0you popped a gasket :O turn that off and unplug it don't want you getting hurt. I would say use a power supply with a good 12V rail to prevent that from happening again. I use only a 600W OCZ PSU for my Gigabype Windforce 3 OC and my OCed 2600K@4.2GHz and I never had any problems even when I had a 570. Either buy a video card thats less power hungry or upgrade your PSU. OCZ is very reliable but dont buy it if it doesn't have enough power for all your componets

What brand psu did you have and i hear its never good to use molex adapters as connectors so im told but mainly i wonder what brand of psu did you use

Sorry for not stating earlier. It was Pulse power. It came standard when I bought all the parts. I found out after it failed on me that it wasn't a very good PSU.

 

[swagatrath]

did you check out the mobo, GPU and other components? was there any damage to the other components?

a good 700w should not need an adaptr, even 550w usually comes with 2x6pin.

better get a good quality psu. im using seasonic 760w gold. before i was using gigabyte odin 550w, used it for 4-5years still functioning now, i just replaced it but it's still ok

You are lucky if your another PC components fine. Never ever choose cheap PSU for budget reason, Its the one component that supply power to all of your PC, working like a heart for human. Get high quality PSU like Antec, Corsair, Seasonic.

That must of been a really bad quality 700w PSU because I am running 2 7850s on my Thermaltake TR2 Bronze 700w and it handles it easily.

pulse power? That doesnt even sound like a legit brand i would rather have thermaltake any day gold sauce.. NEVER buy cheap end psus tho ive seen a site talkin bout that and it showed the whole inside of the psu being burnt into shreads i felt bad for the kid

OCZ is as quiet as two rocks talking while under full load

People should always buy quality power supplys because for one power supplys are pretty damn cheap and second they power your entire system, so OP please do purchase a brand name PSU like Corsair, OCZ, Thermaltake, Antec, Coolermaster, XFX, NZXT, and Enermax and if you want to be running high end cards I would choose a 650w or 700w.

+1. So many mistakes is made when buying lower end power supplys. People think oh its 700W and get a cheap brand and it underpowers the system or burns out which is never good. One of the reasons why i hate dell computers due to how they give out crappy psu on xps

 

[deathstroke001]

OCZ isnt the best brand..

 

[smeezekitty]

This is exactly why not to use a crappy PSU
Atleast it didn't kill your mobo or GPU

Even though the TR2 is far from a great supply, almost any 80+ certified PSU should be atleast usable
since they need to provide their rated wattage to get certified.
