Hi All,

I would like to know if my PSU is enough for my gaming rig, here are my specs:

ASUS strix z2z0h - MOBO
ASUS strix gtx 1050 ti -GRAPHICS CARD
intel i5 7600k - PROCESSOR
WDC blue 1tb - HARD DRIVE
Kingston hyperx fury 8GB single DDR4 ( 2 8GB TOTAL OF 16GB) - RAM
CORSAIR CX series CX500 500W - PSU

Thanks eveyone!

Lucky_SLS · Feb 24, 2017

the cx series is not good, but the cxm is better. also try a rx 470 instead of 1050.
a psu i would recommend is https://pcpartpicker.com/product/fZyFf7/seasonic-power-supply-s12ii520bronze
u could go for a cheaper z270(something like this? https://pcpartpicker.com/product/jtH48d/asrock-z270-killer-sliac-atx-lga1151-motherboard-z270-killer-sliac) to save up to the rx470(this version maybe? https://pcpartpicker.com/product/FgBrxr/xfx-radeon-rx-470-4gb-triple-x-video-card-rx-470p436bm)

Your power draw should sit between 61W and 267W, the Corsair CX 500W should be fine.

Specs-wise It's fine, build quality and performance-wise however It's a poor unit.

With your motherboard + CPU you want a power supply that is actually high quality. EVGA B2/G2/G3/GS, Corsair Vengeance M series.

Thank you for your answers, should i upgrade my psu or stay with corsair cx500?

eidolon171 · Feb 24, 2017

I wouldn't worry about it if it were me. It's 80+ Bronze rated, and well within your required power needs. But it's whatever gives you peace of mind honestly.

RCFProd · Feb 24, 2017

eidolon171 :

The Corsair CX is genuinely low quality. We try to recommend good quality parts, not parts that could easily fail due to cheaped-out Chinese capacitors and such.

Can't recommend a low quality power supply with cheap parts with a near-enthusiast grade CPU+motherboard combo intended for overclocking.

80 Plus rating doesn't paint the picture at all, the certification line is extremely flawed as it is and doesn't tell you anything about the power supply's performance.

Im having a doubt that my psu is too low for my setup, When I setup my rig it sometimes not turning on, I dont know whats the problem, when I tried to put it in vertical position it will turn on but when I tried to stand it up theres no power at all, do you have any idea what is the problem here?

eidolon171 · Feb 24, 2017

RCFProd :

In Corsair's case it means that the power factor has been rated to 0.99. It is a self-regulated standard of power efficiency, true. But is also a technical term that denotes how stringently the device has been tested. This particular device has been rated Class B by EU power standards. It is cheap, I grant you, but that does not mean that it is poor quality. Have a look at customer reviews,

https://www.amazon.com/Corsair-CX500-Supply-Bronze-Certified/dp/B0092ML0MY

RCFProd · Feb 24, 2017

Customer reviews are mostly based on impressions within the first 2 weeks. The Corsair CX is much more likely to fail within 2 years time than higher quality power supplies. That's why we look at actual reviews with professional testing rather than what a customer has to say within 2 weeks of use.

Why 80 Plus is flawed? Read here:
http://www.tomshardware.com/reviews/80-plus-psu-efficiency,4848.html

By the way, any Tom's Hardware regular is with me on this. We have all agreed that Corsair's CX power supply is a failure.

Customer reviews also don't tell much in the first place. Why? If a customer is using a low-end CPU with a very efficient and low end graphics card like the GT 730 1GB, he/she is less likely to suffer from performance issues in the first place.

Torture the power supply with the highest loads and that's where you might kill a bad power supply within no time. Why do you think Corsair came up with a revisioned white label Corsair CXM in the first place? Because the first one is bad.

Tom's Hardware PSU tier list:

Corsair CX - tier four

Built down to a low price. Not exactly the most stable units ever created. Very basic safety circuitry or even thin gauge wiring used. Not for gaming rigs or overclocking systems of any kind. Avoid unless your budget dictates your choice.

eidolon171 · Feb 24, 2017

Your tone is very presumptive. As you can see if you look at my account I have been on Tom's for a long time, so saying that any "regular" here would disagree with me is not true, since I myself am in fact a regular. I am also an electrical engineer, and I happen to specialize in power distribution and signals.

Your opinion is not uncommon, but I believe that customer reviews are a useful tool in gauging customer satisfaction and can be observed as an indicator of product value.

As for the ratings standard I happen to appreciate the 80+ standard and find that it has been a useful indicator of quality. This particular power supply is designed to deliver up to 264V of AC electricity, therefore the likelihood that the user, with the aforementioned specifications would overload this power supply is extremely unlikely.

The Tom's reviews are not worthless, but there is no data to back up the claim that the PSU will break down faster than an EVGA G2

So as an electrical engineer, what is the benefit of the power supply that delivers up to 264V of AC electricity? What does it tell you about Voltage regulation, ripple suppression and hold-up time for an instance? Also, are you aware that the Corsair CX is rated to only work at and below 30 degrees celcius?

You don't even have 200 posts, I'm looking at users who have been posting here regularly for years and have over a 1000 replies to certain topics.

''The Tom's reviews are not worthless, but there is no data to back up the claim that the PSU will break down faster than an EVGA G2''

Enough data that hints towards it actually. http://www.overclock.net/t/1431436/why-you-should-not-buy-a-corsair-cx430-500-600

eidolon171 · Feb 24, 2017

Square voltage is a component of the power law, and is one factor in determining quality. The modulated 6-10A choke is high enough to garauntee appropriate saturation current for 264V up to about 550W. The 47Hz-63Hz variable oscillation frequency is fairly standard ripple protection for devices that include unshielded transformers (shielded transformers usually have oscillators that operate between 40Hz-60Hz). Hold-up time is not very important unless you are prone to constant power outages. And no I was not aware that the CX500 was rated below 30°C, that conflicts with their own datasheet which clearly states 44°C. I realize you are only asking these questions because you doubt my credentials, but as its no skin off my back I'm willing to give you what you want.

More to the point though friend, your tone is getting more and more combative. I have traditionally used private messaging more than posting, as I have a lot of friends on Tom's, and we only converse through the site, but I've been coming here for a very long time. You laid out your opinion, and I laid out mine, there's no need to make it into a personal issue.

RCFProd · Feb 24, 2017

I'm not combative, just hoping people move away from the Corsair CX. It's no coincidence that people seeking help here are mostly budget power supply users with either an EVGA W/B series or Corsair VS/CX units or something comparable, and not Seasonic's.

Why take a Corsair CX when a Seasonic S12II costs as much? The Corsair CX isn't even priced that decently, there have always been better power supplies for the price, with the Corsair CX430 being a small exception from time to time.

eidolon171 · Feb 25, 2017

Both the tests run here,

http://www.overclock.net/t/1431436/why-you-should-not-buy-a-corsair-cx430-500-600

and here,

http://www.guru3d.com/articles-pages/corsair-cx600m-psu-review,1.html

confirm that the Corsair CX series PSU's are neither impressive, nor defective. They are simply mediocre. They meet their specified qualifications accurately, and consistently.

Aside from that, RCFProd you may not perceive your comments as combative, nor might you have intended to be combative. But starting with the statement

"By the way, any Tom's Hardware regular is with me on this."

Which I feel to be a condescending, and exclusionary statement. I let you know in my next post how I interpreted your comment, and defended my position as a long-time member of the community, and of my chops as it pertains to circuits, and computer hardware. Your response to this was emphatically hostile.

"So as an electrical engineer, what is the benefit of the power supply that delivers up to 264V of AC electricity? What does it tell you about Voltage regulation, ripple suppression and hold-up time for an instance?"

Demanding that I prove my credentials by answering basic electronics fundamentals questions (which honestly anybody could just google, and don't really prove anything). And then you add this,

"You don't even have 200 posts, I'm looking at users who have been posting here regularly for years and have over a 1000 replies to certain topics."

This is a demonstrably combative thing to say. You are suggesting What? That infrequent public posts are an indication of ...?
Well I assumed you meant ineptitude, considering the context of our disagreement. Listen, I am fine with a heated discussion based on the merits of an argument, but there is no reason to make broad, judgmental statements about each other in order to endorse, or dissuade a PC buyer from making a particular purchase.

USAFRet · Feb 25, 2017

I'm seeing a lot of personal attacks in here, from multiple directions.

Is anyone volunteering to take a vacation for a while? No?
Then leave out the personal attacks.

Bring the facts, or don't come at all.

COLGeek · Feb 25, 2017

Lets all remain calm and civil please. Just a reminder. Thank you.

4745454b · Feb 25, 2017

I don't mean to start anything here, but I'm probably one of the few people here who don't cringe when I see someone using a CX. As mentioned above, they are low end, but they aren't junk. Using something low end isn't horrible. There are WAY worse options that could be used. WAY worse. For his load at stock he should be fine. I don't think I would OC with that PSU. It is also very odd that so many good/great parts were bought with such a low end PSU. Why buy a 7600K with a Z board if you then pair it with a lower end PSU that can't really handle the heat (literally in this case.). Some better parts are in order with this build, but it's not going to blow up on him. Depending on the price paid and budget he can return it and get something better, but it's not a fire hazard PSU shaped object either.

RCFProd · Feb 27, 2017

^ The Corsair CX's price point is too high in most countries, for the performance it gives. Whilst the tests may surpass, there are better options for the price. And for the price, you do want the best possible option for a setup that's going to be overclocked on.

That's why there isn't much reason to say ''Yeah go ahead'' in my opinion, when something better could be suggested for the price.

That being said, no signs of OP replying.

user11464 · Feb 27, 2017

I have a CX500 as do many people, and it will be fine for your build... however I only have one complaint on it.

The 24 pin connector is a super tight fit on my motherboard, and I've seen many other people have the same problem. It's so tight, you have to bend the motherboard(or be smart and put fingers under it) to get it all the way in. You have to pry it off with a flathead screwdriver and I feel like I am going to uproot the male end on the motherboard.

While this psu has good reviews and a good warranty, the fitment makes me wish I would have bought a different one. All 24 pin connectors are tight, but this one is unreal. I love corsair, but take my advice on this one and skip on it.

4745454b · Feb 27, 2017

Price is something I disagree about a lot with many people. Jonnyguru even has price a part of the final score. I can see mentioning it, but the cost of an item can very. Sometimes a lot. More so with "flash sales" and the like.

https://www.newegg.com/Product/Product.aspx?Item=N82E16817139027

At $55 yes, it's much to expensive. At $35 it's probably one of the best option. I've seen it or the CX450 hit $25-30. It's honestly hard to get any quality PSU that cheap. Seeing as the OP didn't include the cost of the items it's hard to know if he overpaid or not.

user11464 · Feb 27, 2017

4745454b :

I bought my CX500 with the $20 rebate too... and the next day, the CX600 and CX450m were on sale for the same price after rebate. lol I hate flash sales.

logainofhades · Feb 27, 2017

For the combo above, the CX500 shouldn't have any problems. CX's get their bad rep, due poor longevity. Their caps have a low temp rating, and they tend to fail. Nothing that will kill other hardware/start a fire, but yes there are better options out there, at similar prices.

user11464 · Feb 27, 2017

they have a 3 year warranty now, and corsair has good customer service, so it's not as bad as people make it out to be. however I simply would avoid that psu for the reason I mentioned earlier. the 24 pin connector is notorious for being a pain in the ***. that is coming from someone who owns one and that is my only complaint
