Seems a good price for this quality power supply.

I won't copy out all the blurb. Suffice to say, it is really well reviewed.

It is a previous model, which is probably why the price has dropped.

no forget the watts, it is about what the psu can deliver on the 12v rail, thats the crucial factor and this model doesnt supply enough,especially in high end cards like that

agree, had a few of these and they were completely inept in supplying enough power to a mid to high end gpu under any form of load.

Avoid.

Are there any specifics on what the PSU delivers and what the card needs? It's specced for 38A/456W on the 12V rail.

When we get people posting mid-range PSU's, I always feel there's an element of responses from those looking to justify their own spends on a PSU.

Jonny guru reviewed the cx430 variant and gave it a good score: jonnyguru.com/mod…214

This looks like an ok choice for a budget gaming build

It's because you need at least 10000 watts of pure power in order to use a low to high end graphics card. Infact forget any PSU there all "inept". Just hook the graphics card up to the mains.

Thank you so much for the correction kind sir. I'll sleep better tonight knowing people understand my spelling was incorrect.
Voted cold. These are awful.

I had a Corsair CX400 (SeaSonic OEM) years ago and it was fantastic.

I bought one of these CX500's (CWT OEM) to troubleshoot a friends system. Opening it up alarm bells starting going off when I realised how light it was compared to the CX400. Supposedly the CX500 was a 100watts more powerful when in reality it was less powerful then the CX400 version I had.

Troubleshooting my friends system under high load this CX500 PSU was unstable. Swapped with my CX400 and my friends system was stable even after extended testing.

A few years later I came across another system that with a i5-4670k was crashing on entering standby. Opened it up to find another CX500. Swapped it out instantly and sure enough the system was able to enter standby no problems.

I love Corsair. I've bought many of these products over the years. However these CX500 made by CWT are cheap, nasty, rubbish. Do not buy.
Thanks for posting, not sure about it though - will research a bit. Get another £5 off with the Amazon toolbar offer at the moment - hotukdeals.com/dea…168

It kinda says on Corsairs website not to
The old CX (green label) use cheap components, a basic design and have very little protection features. Anyone who frequents PC building forums will know these have a poor reputation for developing stability issues after a period of time and in some extreme cases they fail and damage other components (back to lack of protection features). I have lost count of the number of forum threads that start something like this, “my pc I built a year age has developed a problem where it randomly reboots during gaming” and the problem turns out to be a green label CX PSU. They work when new but don’t last under gaming conditions, when gaming the psu is put under high load for long periods of time and these low quality units just deteriorate too quickly.

Even Corsair knew they had a problem but completely redesigning the CX range but rather than admit there was a problem and releasing a new range and dropping the CX name they just changed the label from green to grey.

likewise witnessed numerous posts on pc and gaming forums with people describing very similar symptoms all caused by a cx psu and resolved by changing the unit for an evga or similar.

As said in an earlier post, these are a poor psu and wouldnt trust it any pc, gaming rig or not.

Agree, personally I would not use in any pc but I do know people who have used in basic office pc’s and they have been ok. Then again those pc’s probably had a peak of 200w and 99% of the time ran at less than 120w.
Well perhaps I'm the only person here but I find these CX power supplies to do just fine! I have one in my personal gaming rig and in many of friends and families computers and have had no issues whatsoever. CX series seem good, but the VS series have caused me nothing but issues.
Here is a list of psu requirements with amperage for modern graphics cards. forum-en.msi.com/faq…-20 as you can see this psu will handle anything from the latest gen on paper. You should heed warnings about build quality from others though. They are only trying to help make an informed purchase.
unless something has changed these are still very good PSUs. At the computer shop we used them all the time.
Green label Corsair CX's are ticking time bombs - look for the grey label CX's they're more recent and safer (supposedly)

I have this one over 5years and no problems ;-)
I don’t use cheap PSUs any more and advise the same of others.

This is probably fine for most builds but people just look at the ‘claimed wattage’ and that’s it. That’s also why there are tons of 800W cheap sub-£25 PSUs around because it plays on the marketing.

Just look at the tier this thing sits in:
tomshardware.co.uk/for…tml

Of course, you can buy it and of course, it could be fine for ages but it’s a false economy with even a half decent CPU and GPU. For an office machine with integrated graphics, no problem. Cheap capacitors and low grade fan is one of the big failure points.
I never thought this would have generated so much debate. I am plugging this into a 1050ti. If it doesn't hack it, it will go back.

I can see there are a number of people who have concerns about this supply. But equally, there are hundreds of really good reviews across the web. I guess it depends on particular circumstances.

Good thing is, as it is Amazon, I will get a refund in the first year of there is a problem.

And yes, I did use my Amazon assistant £5 to bring the price down a bit.

Thanks to everyone for the really helpful discussion. I will certainly be looking at my performance/stability more carefully as a result.

These are bad . I have only experienced 2 of them and one failed whereas the other had a major manufacturing defect . I agree that Corsair are a decent make when you go up to there higher range but these arent well made .
not sure why the amazon reviews are so positive as a quick Google’s of pc forums and you can find plenty of people who have had issues like the ones I did with these
You have to balance the positive reviews against the negative. This is the level of Corsair PSU dominantly in the bestsellers on Amazon, so of course they are going to be quite frequently posted about on PC forums.
Had one for 4-5 years now on a 660 ti's, i5 k, overclocked all and don't have a problem whatsoever.

I tend not to get involved with anything to do with "gaming" on this site as most people on here having got a f'n clue.

I'll be upgrading to a 1070 soon and keeping the same power supply and I guarantee I'll have no problem, ignore the plebs.
Would people go for this CX500 or the 3 year newer VS550 for a touch more power and a touch less money?

Didn't they just shift them to the VS range.

No, the VS range still remains and as far as I know the design and components used are unchanged. It seems Corsair just redesigned the CX range and relaunched with a different colour label.
Confused why this is a deal pretty average psu

You can get a Aerocool Integrator 500w for £30 will be just as average

I mean the VS range is the bottom of the pile a bit like the original CX600s. I bought a CX/cwt about 6 years ago and it lasted just over a year. Would cost too much to rma it so I binned it instead. I think they cost about £40 as they were cheap and nasty. Looks like the VS are HEC built but are probably on par with the low end CX PSUs

These are examples of why people find pc gaming annoying. You can't buy anything without it been not good enough or there's better. I've got 500W in mine with gtx 980ti and works fine.


I'd definitely make you sure look at your build to see if it's compatible but don't just quickly say it's rubbish.
Seems a decent price, heat added!

Tho all the posts mention graphics card, you'd need to keep in mind your processor load too (not that many go over 135W) and anything else you're going to want to have connected - tho these are likely the 2 biggest loads, they all add up

What do you do with the other 14 hours? Do you sleep?
Having worked at a major PC component retailer, and seeing the amount of cheaper PSUs that got returned after going bang (even from big brand names). Believe me there's a reason they are cheaper.
My power supply arrived today. Someone earlier in the thread described it as a lightweight supply. Believe me, it is anything but. First impressions are it is a quality build. The cables are plenty long enough and they provide a cable tie kit for management.

I chose to avoid budget, sub-£30 power supplies. But, I could not justify a £80+ supply. First impressions are that this fits my needs perfectly. It really does look like a quality bit of kit.

But, i haven't used it yet. As I said before, if it doesn't stand up to the demand, it will go back and I will learn a lesson. Based on what I have seen so far, it is pucker!
