Corsair RM650 -just died...

Any idea what could have caused the following..?

I have only been using the PSU for the last week to test fans and pumps etc.. Finally came around to test my full system. I plugged the 24 pin in, the CPU power, 2 pcie power cables and an accessory cable for fans pumps etc.. Hit the power button on my PC and the PSU made a click sound and white smoke came out the top. It's blow the fuse in my extension block etc

I am guessing the PSU is now dead

So, after last night, I plugged a spare PSU into the motherboard. The LED's light up on the motherboard, and also my USB power HDD starts up when I hit the power button. But nothing else indicates that the system is turning on or boot, (no system fans spin even though they are plugged into 4 pin molex).

Is this a sign my new motherboard has been fried by the faulty PSU?

No beeps or anything, nothing off the LED post either. My cpu and ran is fine, I've put it back into my old setup and it works. PSU is dead for sure. I've tried using my atx bridging tool to see if it will power just fans, and it won't.

I've only had the PSU about 2 weeks so I'm taking it up to overclockers with the motherboard for testing Friday/Saturday.

I'll see if I can get a refund instead of a new corsair unit then. Do the super flowers have zero rpm at low load?

I'm not going to be drawing much power as I'm only powering a i5 4670k @4.2 and a gtx 970.

But I prefer bigger wattage power supplies so I'm not taxing it. Also needs to be able to fit in the prodigy

Any idea if overclockers will just refund me instead of replacing it as I've not even had it a month?

I've got a seasonic g series in my other pic. It seems good, but the fan is a bit grindy sounding at times.

Ok right. So after leaving the battery out my my Asus Maximus VII Impact over night it seem to be booting up fine now.

Before getting the Corsair RM 650 I read somewhere that they and the seasonic G series PSU's are made in the same place but basically come in a different box..

Nope

Corsair RM 650 is made by a factory which is a company called CWT.
Seasonic has its own factory who make for many other brands of PSU's include some of the Antec PSU's. Seasonic is an actual manufacturer same as CWT.

Corsair are NOT a manufacturer, they buy PSU's from a company who brands them up for Corsair. Corsairs older units were made by Seasonic, but around 2011 Corsair switched to CWT to make PSUs for them, the Corsair RM series were released in 2013 and are 100% made by CWT. One of the reasons behind it was because CWT could build PSU's far cheaper than Seasonic, but with that came the negatives of quality and reliability.

Here is a list of PSU's and who makes them.

Thanks, that's good to know. Next time I'll hopefully make a more educated choice!

Bryan Kortez - I think it was just unfortunate that you got a bad unit from the get go.. We can always provide assistance if you need to get a replacement.

I have put a RMA in with your team. So I should be in with the unit today or tomorrow.

Something I'm not happy about with this PSU, is how tacky the connectors feel. They really don't like plugging into the PSU or components. You have to put a fair bit of pressure to get them to click in place.
