FAO: GreyBeard; Corsair RM 750.

Hi Greybeard,

Wondering if you can help, or any of the fellow OCUK fellas.

Recently, my PC has been randomly shut off while under load, I have done that basics like removing Overclocks, etc... But I have noticed that whenever it shuts off the PSU is so hot that it cannot be touched for anymore than a few seconds, this worries me as I have never seen this happen before.

I have made the PC shut off twice when folding, and the same thing has happened, with the PSU being really hot to the touch.

The PSU is question is a RM 750, while it has been fine for over a year, this has randomly started this week.
Upon further investigation, I have stumbled across this thread on the Corsair forums: http://forum.corsair.com/v3/showthread.php?t=123484

Bear in mind my Unit starts with the lot code 1339, which I believe is part of the affected units with only one transistor for the fan system instead of two.

I have been in touch with the Corsair RMA service, and my ticket number is: #6635357
In terms of postage, usually when dealing with OCUK I have had a prepaid label to return the unit. But i'm going to RMA directly with Corsair, as i'm aware that there is a new RMA centre in Bolton UK.
So in terms of postage, is there a return label which can be used? I aware that due to the weight, it can cost quite a bit to post is all.

Any help in advance is greatly appreciated.

Anyone?

Hey

I am doing the exact same thing with corsair right now and RMAing my RM850. Personally I pushed corsair to provide a postage label at their own cost due to it being an inherent fault with the unit rather one that has developed over time.

And to their credit they have provided me with one so I will be sending off my unit as soon as my temp stand in arrives.

An update on my part too, after a little push (Winky

) I have also managed to get a free postage label.

I will package it up and send it off, but need to find a local DHL centre first.

Edit: what was what with your PSU?

Disco_P · 18 Jun 2015 at 08:27

At first it was that my PC used to cut off so I thought it was the described thermal issue (case frequently gets that hot and the unit gets no passive airflow). Turned out to be that my 8 pin cpu wasn't plugged in correctly.

However the unit's fan seems to be spinning up massively rather than gently and is very audible and annoying. I told this to corsair and they replied with:

If you are unsatisfied with your PSU, we can always go through with an RMA.

I think you can call DHL and have them pick up your unit. At least that is what my email says.

russell664 · 18 Jun 2015 at 23:16

I have not been told that, the issue for me is, where is the local drop off point.

I could have them come to work, but would rather not, as people can get rather nosey about my PC building habits, which then results in them asking how much I have spent in total which makes me sad.

Disco_P · 19 Jun 2015 at 10:34

Just arranged the pickup, whole process was really easy.

russell664 · 21 Jun 2015 at 20:55

Dropped mine off at Ryman. Never seen such clueless people in my life!

Disco_P · 22 Jun 2015 at 14:47

I organised a pick up and the DHL man got completely lost!

Been reading about the RMi line, they have stupidly good ripple suppression.

ShivP · 22 Jun 2015 at 15:20

They also have stupidly bad prices at the moment, hopefully they will become cheaper than G2

russell664 · 22 Jun 2015 at 17:57

Is that what the unit will be replaced with you think?

Disco_P · 23 Jun 2015 at 02:26

Probably not. I just found out that corsair now has CWT versions of the rm750 and rm850 so we will probably end up with those.

russell664 · 23 Jun 2015 at 09:48

Argh, well looks like I'll be selling on after then. Just got a Silver Stone Strider Gold 1000w.

Disco_P · 23 Jun 2015 at 14:23

I was eyeing that up on the MM.

russell664 · 24 Jun 2015 at 21:19

I got mine from OCUK, actually went into the store as I needed a PSU exactly the same size as the RM, but with more power. Came in with measurements and everything!
The reason was because I would have to re-do my whole loop if it was bigger, so wanted a decent unit.

Was speaking to the lad about it all, it is like nerd haven in there!

But yeah, if you are considering it, get it, it is a great unit.

Disco_P · 25 Jun 2015 at 10:44

Well bumfluff.

Rma has been approved but the replacement unit won't be sent until 13th July. Just great. Gonna have to look for a unit on the MM.

russell664 · 25 Jun 2015 at 12:59

Mine hasn't arrived as of yet, was in Belgium last time I checked.

Have they mentioned why it will be on the 13th of July?

Edit: Mine is now processing.

Disco_P · 25 Jun 2015 at 16:28

They are out of stock of RM850s

Disco_P · 25 Jun 2015 at 21:41

I asked this morning whether there was anything they could do to shorten the delay such as allow me to pay to get a better model.

Normally their warranty policy doesn't allow for upgrades but because my unit is out of stock they are making an exception and will send an RM1000 for no extra cost in the next couple of days! That is a very impressive level of customer service.

There really is no harm in asking :cool:

russell664 · 25 Jun 2015 at 22:18

Mine was an RM 750, so may well have some of those, it is in the 'processing' stage as of now, roughly how long did yours take?

Your right there is not harm in asking, will see how mine pans out too.
I would like to say thanks for sharing your experience with your Corsair RMA too. :cool:

Finally eliminated the whine issue from my PC, thought it was the new PSU, but it turns out I tuned my pump seeped, and doing so made a massive, annoying whine because of the way it is mounted, really need an EK tube res!
