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?
 
Corsair RM units are pretty poor quality sadly (well, some, check johnny guru), PSU is most certainly dead if it smoked.

As for frying the motherboard, not sure. Any beeps or anything? if it doesnt post at all and the PSU is fine its either RAM CPU or motherboard so process of elimination I guess.
 
I certainly wouldn't rate the Corsair units unless they're the AX range. You should be able to RMA it but I suggest you pick up a Superflower as a replacement and when the returned unit arrives back to you, sell it!

You'd also be better to try the paperclip test before confirming its dead!
 
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?

Not 100% sure about super flowers, but EVGA G2 (rebranded super flower) doesn't have zero RPM , however the fan spins so slowly it makes literally no noise anyway until it gets over 600W used (on the 850W model). I am glad I got this PSU, a great purchase.
 
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 :D

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

How come?

They're on the same scale as XFX and Seasonic, Seasonic being the #1 brand for PSUs (XFX being the OEM) - Superflower are one of the most solid, stable & hassle free units you can buy! Well worth the investment!

All you have to do is review the general hardware thread and see the most common spec'd unit - Superflower! Gibbo will vouch for the number of units sold!

The bonus to the EVGA is the 10yr warranty! I'd still go with the Superflower ;)

How come...? I am confused

If you mean why did I got for the EVGA G2 over the Superflower leadex? Longer warranty, the same internals and it was like £20 cheaper as it was on offer at the time for like £85.

I had an XFX XXX 750W before this and it was a great unit for a great price, but its fan was just far too loud for me.

This ^ Sorry for being unclear lol, I know SF make the best units, next to seasonic, I wouldn't recommend anything unless it was made by those OEM's.

The G2 750W and 850W both have zero fan mode. There is a switch on the rear to select 'eco' mode. Superflower have the same thing.

As mentioned above though, not all of them have eco mode.

What the.... How did I not notice this both in the reviews I looked at... AND when I bought the unit! It's been there all along! Now to turn it on... :D thanks
 
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!
