Beware cx500w when overclocking!!

[Snedz1989]

Just a quick post about cx500w.

 

I see so many people hating on this psu. From personal experience i would recommend this psu for any budget build and maybe some mid level builds. You definately could do better for a little more cash but if your in a rush to get one for a £50 budget and pc world is your only option then go for it.

 

But!! If you're going to be overclocking do not increase your voltage at all.....

I've been using this psu for 10 months powering :

Asus formula v motherboard 

Fx 8350

Rx 460

16gb ram

 

And worked fine till greed took over and tried oc'ing from a stable 4.4ghz to 4.8ghz. Was a stable oc, but turned on the pc in the morning before work, made coffee and came back to a dead pc...... 

I only upped the voltage to 1.39v from 1.32v and that was game over. Also overclocked the gpu too which didnt help anything.

 

Up until this point it ran fine, no problems at all. Luckily this experience has forced me to learn everything about psu's to avoid this happening again and am waiting on a evga 650w gq gold rated psu for £71, only £21 more than the cx500w lol

Trash psu don't reccomend it

[pebble guy]

Yea. Low tier PSU's are not an good option for anything other than basic builds. With those you really get what you pay for....

Well the FX eats power for breakfast like a maniac. I mean 200W is like nothing for FX cpu's. Especially when overclocked.

If you have a current maintstream platform like ryzen or coffee lake you'll be fine with overclocking. You might even get away with a 500W for an overclocked threadripper.

But if you have a socket 2066 platform, you might want to be careful when oc'ing. There are reports out there an overclocked one goes easily over 500W.

Attention viewers: water is wet.

Lesson learned: don't pair a mediocre budget PSU with a very power hungry CPU and expect it to handle it well. The CX500 isn't a bad power supply on its own, it just wasn't made to tackle stuff like this.

Was more of a last resort recommendation. Lile it was for me when i bought it lol

The green label versions are quite bad for gaming builds, the newer 2017 ones are just okay budget PSUs

 

But these things are only made for office builds.

Quite frankly this ^ probably was a bigger issue than the PSU itself, FX is obsolete and dead in 2017.

Just posted a thread about dealing with this. Have a look and help if you could ?

It isn't an inherently 'bad' PSU, but for how much money it costs, you can get better....

 

No sense in buying this: https://pcpartpicker.com/product/hgGkcf/corsair-power-supply-cx500

when you can get this (more wattage and won't die the moment you try any OC): https://pcpartpicker.com/product/3F2rxr/corsair-cx-2017-550w-80-bronze-certified-atx-power-supply-cp-9020122-na

 

(note the CX650M is currently on sale at that price, but that is the standard price of the CX550M, which is still better in the above mentioned ways)

 

and if you're looking for budget PSU's, there are equally good, but cheaper, options: https://pcpartpicker.com/product/MfvZxr/evga-450w-80-bronze-certified-atx-power-supply-100-b1-0450-k1

https://pcpartpicker.com/product/Q7L7YJ/corsair-cx-2017-450w-80-bronze-certified-atx-power-supply-cp-9020120-na

or

https://pcpartpicker.com/product/4FH48d/evga-600w-80-certified-atx-power-supply-100-w1-0600-k1

 

 

So its not "bad".... it just doesn't make sense based on the competition on the market today (and those are JUST the offerings from corsair/evga). And if you ask any more than the bare minimum out of it you're going to get the result you did.

it is neither of those things. if you're chasing 60fps gaming its still quite competent. I mean not ideal, and certainly not an efficient CPU, but if you're a budget user it'll definitely get the job done.

Sure if you already own one you can hold to it but NOBODY should buy one used regardless, at least not when a dirty cheap 70 dollars G4560 with absurd better support, better energy efficiency can out perform any FX line up at all...

 

There simply is no good reason to get one of these used nowadays but to make the sellers day that they managed to get rid of it

Snip

and if you throw streaming into the mix? or editing/rendering? or any kind of core count scaleable task? Don't get me wrong, not saying the FX8350 is good or amazing or whatever, bur the DDR4 RAM you're going to have to pair with your G4560 is probably going to cost as much as the entire FX platform. Definitely not a good deal if you're buying new (unless you can get a killer deal at a place like microcenter), but with how many of these things are out there, finding a good deal on a used setup shouldn't be that hard at all. And if you already have one its far from "dead and obsolete" for many users.

What the hell are you talking about?!
That one has _NOTHING_ to do with the 500W version. Totally different plattform...

1. FX8350 is exactly equal to an i7-3820. An i7-3930K consumes more power than both.

2. The FX is stronger than ever and, if the game supports it well, can perform very well...

1. PLS STOP IT!
Stop these bullshit games, that lead to nowhere!

Especially since you can find many examples where the FX8350 performs really well and is around an i7-3770K and sometimes even 4770K. And remember that the FX was around 150€ at the time! 

Way less than every i7 at the time did cost!

 

2. the FX isn't that bad, you can play games well with it, what else do you want?
3. Depending on the Workload the FX can slap many other CPUs of the time around.

4. The FX8350 was introduced before Haswell!!

 

And without overclocking and a decent Board, power consumption of the FX8350 isn't that bad. I had one, measured it and the i7-3930K I have now consumes much moe than that.

 

 

Anyway:
If the CX500 isn't broken, it should be more than enough for an FX8350 with a good mid range graphics card like a Radeon HD7970GHz Edition - wich is around 350W under normal gaming conditions.

For the record i bought the cpu second hand with a asus formula v motherboard, 16gb ram for £200 in late 2015

WTF?  Not the same PSU.  Not even based on the same platform.

So you're 100% sure the PSU is dead and not something else that died due to the OC?

 

You've already troubleshot that?

[Snedz1989]

90% certain its just the psu. Tested using a psu tester. Also the power led on the motherboard power button still lights up, just like the last time lol let you know tommorow when the new power supply comes. Wish me luck lol

2015 was a good time.. on my previous build I picked up 16gb of 2400mhz gskill ripjaws for £70, now that costs about £140

Personal experience means nothing. User reviews mean nothing. The only reviews you should look at it professional reviews, as they take apart the unit and test it with expensive equipment. That unit is a bad unit, so it honestly should've been trashed.

 

The minimum budget unit I would recommend is this unit: https://pcpartpicker.com/product/FQ648d/corsair-power-supply-cp9020101na

Just my 2 cents on it buddy lol i by no means claim to be an absolute authority in any pc component lol

Either way, this isn't a PSU that should be recommended.

[Snedz1989]

I agree. Like i said "if you need a psu now for £50 and pc world is your only option, get it".

 

Beleive me having went 2 days without a pc because of that psu and my own greed im not a fan of it at all lol
