CX PSU Questions

[iamdarkyoshi]

So I want to buy a CX PSU. Why? So I can put it through its paces. Running it in hot ambient temps, running it at full load for extended periods of time, ect.

 

If it lasts more than a month, then maybe people on the forums will complain less about them sucking. Sure there are far better options, but I have seen people suggest expensive PSUs for little office PCs and stuff.

 

I want to put one through heavy load and see what happens. If it lasts without issues, that would be cool, and if it violently detonates in a shower of sparks and flame, that would be cool too.

 

 

What one should I go with?

 

 

Also, if anyone wants to donate their PSU, no matter how terrible, I might as well put it through its paces. I threw away about 200 pounds of old PSUs, should have kept them lol

Get a CX750M.  It's the one I've seen most on the forums.  Make sure you have a fire extinguisher also.  And don't burn your house down.  Good luck!

The thing that ticks people off is the 30c max operating temp

And so maybe I would try running it with a faster fan inside. Science.

Ooh, spendy. I might have to wait till that goes on sale

CX430 and 750M

Edit: I can donate the PSU from my dad's old PC, just to see how shitty (or good) those OEM ones are. Just pay shipping cuz that thing is heavy.

People liking silence is a thing and having rooms with over 30c ambient is also a thing

I've been using my CX600M for over a year now, with my pc on probably 16-18 hours straight per day, not a single issue with it so far. (Specs in signature)

 

Though in the future I would like to get a better PSU, perhaps a fully modular one with sleeved cables.

put the CX430M and CX500/M and CX600/M

 

 

i am using the CX430M here in my HTPC

 

no complains

CX 750. It's the one that really annoys me, as 750W is complete overkill for anything less than a "High-end build" and there are better choices to protect your 1000$+ investment. The CX430 is great for office computers (I use one) and the 600/500W are fine for budget builds. Also, the CX 430/600 seem to get better reviews than the 750W.

[LeapFrogMasterRace]

Really? I see cx 600 the most

[iamdarkyoshi]

I didnt know these damn PSUs were SO EXPENSIVE

The CX bashing has gotten out of hand. A lot of people that say it's terrible don't know why it's considered bad for gaming builds, so they just say it's bad all round. 

 

The PSU itself is actually okay, provided it's used for the correct type of system (office, HTPC and other basic uses). 

 

It's not going to blow up, and it's not likely take components with it if it does die, it's not a no-name $10 unit. It's also not guaranteed that it will die if you run a high end system on it, so running a single test doesn't really help that much. The issue is that it's simply not rated to operate over 30C ambient (not a difficult temperature to get to), and the capacitors and components in general are not designed to take heavy loads. 

 

I'd expect crashing, artefacts, buggyness and general instability if you push it, but I wouldn't really expect an outright death of the PSU unless you're really harsh on it.

And this was pretty much was I hoped to prove. But the problem with this is that I didnt know they cost so much...

Remember though that the /Ms and revision 3s of the CX are much better, though still not great performers electrically and not great for the money.

 

I'd suggest getting a used CX600 or CX500 (likely to be an older one) and run it through the world. I don't like the CX series mostly because, on sites like Newegg and Amazon, the older and newer revisions are often clumped into one group, meaning you're likely to be paying for the wrong product.

the CX psu is ok for light workload like office works,internet browsing and stuff like that,(not gaming-overclock-rendering) the problem is the maximum operating temps and the builds quality components, since the capacitors are not rated for 105c, but for 85c, made from CWT. Keep in mind that many 600w/750w/850w+ models are older gen GS psu from corsair, and they are consider better than the rest of them.

A Little bit of common sense here guys,the CS/CX lines are not meant for high-end gaming/OC'ing/Heavy workload builds, that is why the HXRM/RMi/AX/AXi lines are here.

 

The lower tier units aren't bad when used in the correct way ie: office/email/web use...

 

The general populous doesn't grasp the difference, they just see "80+ Gold, fully modular 600w" or whatever and assume it will be great for their gaming build because it's relatively cheaper than others...

600 Jiggawatts for 29.99$?!? GIFF ME! /s

They'll still complain. Guaranteed. The only thing that will become of your experiment is advancing your own knowledge. 

Sounds like a neat test, though. I have no problems with CX. I had one with a 4690k and R9 290 for a while.

Gotta say, the CX discussion in this thread is very mature and has a lot of good factual information for those who are considering the CX PSU in their system. It is refreshing to see rational conversation like this in this great community, where the responses are well thought out with a good reasoning behind it. It's definitely a lot better than seeing those type of hit and run post which doesn't really help the OP for the most part. All it really does is a disservice to the community, nothing more.  

 

+rep to those guys (you know who you are)

 

Well... there's a few outliers, I hope they get my point

Oh I totally agree. I mean sure, the CX is not meant for a 5960x with two GPUs, it is meant to be a simple, affordable PSU for simple computers. But I do not understand why people go ahead and bash it. it is like saying that a prius is not a good car because it cant climb a muddy off-road hill. Well of course it cant, its not supposed to!

What?

Watch the ending.

I have seen it plenty of times and to be honest, the video does not help a whole lot in threads about power supply choices. Sure, it makes a point, but not in a positive way.

[iamdarkyoshi]

Honestly, it depends on the build.

Say you're using a 4460 and a GTX 660, a CX-series PSU would be fine.

Or just a home theater PC that uses onboard graphics and houses a bunch of hard drives that are only occasionally used...

Speaking of which, I need to replace the fan on my mediaserver's PSU. its a stock cooler master case PSU... scary...
