Lately I see lots of hate towards the Corsair CX/CXM series and I don't know why.

I've notice many people tend to bash on any PSU that isn't the VERY BEST, but thats not what the CX series was meant to be, it never was. They were supposed to be cheap entry level PSUs to swap in to replace the Apevia and Diablotek junk that people usually pick up. All the reviews I have seen of them show them doing decently; not fantastically, not horribly, just decently, just like they were supposed to.

Sure the CX750M isn't as good as the EVGA 750 G2 but its also only $60 instead of $95, they aren't meant to be equivalent so why do we insist on comparing them? I've also noticed lots of people, many of whom are just repeating the party line because they don't know better, blasting PSUs that aren't top of the line as being bad which just isn't true.

There also seems to be a lot of FUD about capacitors floating around too. I just came across someone saying that the caps in the CX/CXM series will fail in a year which just isn't true....


Sooooo, why all the hate?

I know what you mean, I don't see why people act like the PSu is going to fail on them within a month. Many people on this forum always say or act like you have to go for the "best of the best" but there are many people who cannot afford such expensive builds and need the best parts.

I don't have hate for them, but I rarely recommend them. The majority of the systems people are building on the forum are high end gaming machines that will be overclocked. If someone is spending $300-400 on a high end graphics card, it makes sense to me to get a top of the line PSU to match it. It doesn't have to cost much more. The XFX650 is always somewhere around $50 and can handle most single gpu setups. So considering that, it doesn't make sense to me for anyone to use a CX series PSU.

But for a system that will not be heavily overclocked and integrated graphics (or less demanding GPUs), the CX lineup is the perfect fit.

Agreed, i had a CX 430 in one machine and a CX 500 in another, both ran for 2 years with no issues, sold one and upgraded to an HX 750 for a GPU upgrade, still running the CX430 in the other machine. Also just built a home server that is usually idling along...a CX430M for $20 shouldn't have any trouble running it for years.

I definitely agree with what was said though, if you're running Ultra or Raidmax type stuff...definite upgrade.

I have a friend who had the CX 750 in his rig, and it's been running fine for maybe two or three years. I think people stay away from recommending these PSUs just to be on the safe side, or they don't know any better.

Or perhaps there's a better quality PSU for not that much more.

I just came across a poster who said that the CX 750 could fail after a few minutes...

I do agree that the comments on the forum about the CX lineup being terrible is not warranted. They are not terrible. Whoever said it will blow up in a minute is sadly misinformed. They are great mid-level PSUs and perfect for mid-level systems.

CX is not bad. Corsair itself recommends it for low-mid uses home/office machines. I know a small IT business which runs around 10 PC's with CX 430 and never had any problem. They are just not for high powered gaming/overclocked machines.

You have to realize that when even experience people like moderators always comment on the "bad caps" you get people who will pass that info on.

It just makes me sad to see people spend $800 on a rig but then shove a CX in there just to save $15 on the PSU...

Any PSU worth it's weight these days has a 5 year warranty. The CX has a two year warranty. It's a fine enough budget PSU but those who can should always spend a little more imo

I have a CX750M that i've had to RMA twice..

The one I have currently is even on it's way out. Used in my HTPC for a year.
When it works, it's great.

I'd like to know too. Had one in my rig for 6 months. Not one problem

I bought a CX750M from Best Buy a few months ago to replace a several year old power supply that had a very high pitched capacitor squeal/coil whine. It was even noisier than the old one - squealing and buzzing like crazy. I took it back and didn't give them a second chance. After searching around the web it seems that's not an uncommon occurrence with the CX line. Ended up getting a Cooler Master V650 (gold rated) and its dead silent.

Rather than to start a new topic,i'd like to know the same thing about the rm series.

Anyone here is bashing on that rm 850watt (for insatnce this wattage) because of the tier list,but has anyone seen real problems? The low(er) grade capacitors are in there,but even sites as jonnyGuru recommend this psu.The issue that the fan wouldn't rev up even above 40°c seems to be resolved too.
I know this is set out to be better than the cx line,but looking how it performs in reviews is it just that.

Is there anyone that can say why this is such a bad buy other than the caps? I've seen no real problems on the web,maybe others know better?
