Is this a good power supply? Opinions please.

No, its not a good PSU. Its mediocre at the very best.

Entrainers 2 points 2 months ago

Its an old unit, and unless its like $10 it isn't a good buy. You can find the much better Corsair CX 450 (non modular) for $21 often

fellway 2 points 2 months ago

It's worth noting that only the 2017 version of the CX (both of which are different than the more-reliable CXM) is better than the 500B. As for the original CX series, it's a toss-up.

tragiktimes101 submitter 1 point 2 months ago

Yeah, I have heard....well lets just put it as less than good reviews on the original CX series.

fellway 2 points 2 months ago

If you already own the supply, if you aren't overclocking, and if it isn't old: I wouldn't worry about it.

If you are buying a new supply, I wouldn't even bother considering the 500B. It's absurdly outclassed by the competition.

For an example, these 4 supplies are much better than the 500B and are either less expensive or similarly priced.

tragiktimes101 submitter 1 point 2 months ago

One question left....how did you compare items?

fellway 2 points 2 months ago

When you're looking at multiple parts in the listing section, click the check box on the far left.

After selecting more than one, there will be a "compare selected" button in the top left (underneath the "Parts" heading) that you can click, which will take it to a page like I linked. As a side note, the compare function is limited to 4 items and will only show 4 of the selected items if more than 4 are selected

Thanks a bunch. Didn't know about this feature.

navarro233 2 points 2 months ago

Wow, but I bought one in $ 30, in amazon, I did wrong? , I want a PC Gamer not so much, but rather for Daily Use, PS: Sorry for bad english :´v

tragiktimes101 submitter 1 point 2 months ago

Np on the English friend! It's not bad if you don't plan on getting close to its stated load levels. It really only gets dicey when pushing higher watts which can cause the 12V to run out of spec from time to time.

Do you have a dedicated GPU? Because that can make a huge difference as they can pull high watts depending on the kind of GPU.

navarro233 1 point 2 months ago

I plan to buy a GPU, but later, because I do not need it now, and if I feel comfortable, without a dedicated GPU, I may not even buy it, xD.

But Well, first things first, Build the PC, but if I buy a GPU, max I choose between this one https://pcpartpicker.com/product/cCDzK8/evga-geforce-gtx-1050-2gb-sc-gaming-video-card-02g-p4-6152-kr and a 1050TI, no more: v

tragiktimes101 submitter 1 point 2 months ago

I would go with this GPU as it has two fans for better performance, cooling, and sound control.

Point you may want to consider most 1050/1050ti models run solely off of slot power on those models two fans eats into your overall power budget and can limit the available boost clocks early and don't really make much difference in cooling with how cool those run.

Its more of an issue with the 1050ti as its fast GDDR5 memory is very power hungry but even a couple of watts saved is better boost performance with GPUBoost 3.0.

tragiktimes101 submitter 1 point 2 months ago

That is a good point. I suppose this concept applies to most if not all non-power supplemented GPUs?

tragiktimes101 submitter 1 point 2 months ago

More opinions please.

The EVGA 500B is very much an inexpensive entry level product and that is exactly how it performed for us today. That said, it is also very much a passing inexpensive entry level product and we don't often get to say that. The downside to all of this is, of course, this product category is usually defined by compromises that enthusiasts would rather not make and that was again true today. From the units mediocre to passable for its niche build quality, to its passing but not great voltage regulation, to its OK Transient Load Test results and DC Output Quality the EVGA 500B was thoroughly uninspiring functional. Certainly, a lot of the very "meh" feelings we have about this unit come from the fact that even ~5 years ago we were seeing this kind of performance in this output capacity among units that were also entry level products.

What saves the EVGA 500B today is pricing. As it stands today, the EVGA 500B can be had at Amazon for $44.99 with Free Prime Shipping and that makes this unit of the least expensive power supplies in this category from a brand that is respected. That right there makes this unit worth looking at for when you need a quick power supply to test something, a low end build, or some replacement when budgets are extremely tight.

Although keep in mind that is utterly fails now in the $40 range due to the CXM and the B3(if you keep it below 450W...)


With the 500B, EVGA did pretty much what they set out to do - release a good, solid, no frills power supply at an affordable price. No, it doesn't have the performance of the Supernova units, but it really doesn't have to. That kind of performance costs money, and if you're shopping at the fifty bean level you simply cannot afford a world class unit. Units like this one are the next best thing. I'd like to see the Japanese capacitors used on at least the 5VSB output, but that remains my only major complaint right now. You could do a lot worse than one of these if all you have is fifty bucks to your name.


EVGA decided to enter both the high-end and mainstream category by also releasing a product for the budget user. The new EVGA 500B surely doesn't provide cutting-edge performance, nor does it have exotic features—it is a simple PSU with a non-modular cabling design, Bronze efficiency, and rather average performance. But its very low price and EVGA's three-year warranty are strong advantages, and it has an interesting look. EVGA usually targets the enthusiast user, but it is nice to see them enrolling into lower-end categories too, where more and more companies are lately trying to establish themselves.

tragiktimes101 submitter 1 point 2 months ago

I really appreciate the opinions everybody. The whole point of this thread was to dissuade someone from using and recommending the 500B. I bought one in the past and had nothing but problem with it. Not a problem since I upgraded. The person that I am referring to wouldn't take the reviews from reputable sources seriously so I was hoping they would take your opinions with more weight. Again, I really appreciate it. Wouldn't want to see someones machine go through what mine had to.

This is what I took from the reviews that I read, and my own experience with the PSU:

Many people would be wrong.

  • Cheap caps.
  • Poor 12v ripple suppression.
  • Poor 12v voltage control.
  • Group regulated design.
  • 40C Ambient.

Am I saying that this PSU wouldn't do fine for a PC that was on the low end and didn't plan on pulling near full load? No. It would do fine for that. But if you have a 1060 and a 1300X (which your proposed build has), even without OC you will be putting that PSU into a wattage that will potentially lead to PC crashes, which is what my EVGA 500B did over and over again until I replaced it.


If you are building a gaming PC with a decent size GPU or plan on OCing avoid EVGA B series like the plague. I would recommend the B3 (which is what I have now) but there is a review that suggests it has a misconfigured OPP, which lead to sparks (without tripping protection) in their test bench.

EVGA B3 Reviews:


The second B3 review is of 750w variant. I cannot attest that the build quality remains the same between the different wattage variants.

Yes, the 750W and 850W are completely different inside than 450-650W.

tragiktimes101 submitter 1 point 2 months ago

I was almost certain of that but had to include it with a note due to uncertainty.
