Alright time for another one of these threads and before i begin i want to say a few words, first off if you have one of these its not going to blow up and burn your house its not that bad its just not very good either, second this is an info thread to help and inform everyone what the flaws of the unit is, if you dont like this and you just want to rage and spam the thread becasue you dont like it then please stop reading right here and go away, thank you very much

First of the EVGA 80 plus and bronze rated units (not the B1 or B2) on paper looks like cheap 80 plus and 80 plus bronze units, but the fact is they are not very good and you should take your money elsewhere if you are looking for one of these units in a gaming and/or overclocking PC, why is that well i am going to explain in more details below.

OEM on these units are HEC or as i like to call them the kings of crap as almost everything they have ever made is not very good, the best HEC unit ever made is the gold rated AeroCool GT series which is on the OCN PSU list.

These units are group regulated as well which mean the voltage regulation is not going to be all that great.

Note that all ripple and voltage results are from the unit(s) at full load
Anyway lets start with the 80 plus rated units (Click to show)
review and pictures are from jonnyguru.com so all credit goes to them and not me as i have not reviewed this unit nor do i claim i have








Folks, what we have here is the exact same HEC design used in the 500B. Just... you know... less efficient and more rippletastic.


A CM6800 is our PWM/PFC controller of the day. That's a Capxon main filter capacitor, there.


Line filtering continues here with two more Y caps, an X cap, and a coil. No surge suppression device is present, but I tend to let that slide in APFC units anyway.


All secondary capacitors come from Teapo.


12v rail ripple suppression is crap its around 90mv and go as high as 105mv, and its been a long time since i seen anything that bad




So there you have it the EVGA 430 / 500 are cheap for a reason as they are not very good to say the least.
Moving on to the EVGA bronze rated units (Click to show)
this time all credit goes to techpowerup for the pictures and info





The OEM of this unit is HEC/Compucase, and the 500B actually shares the platform with the be quiet! L8-500 unit we reviewed a while ago. HEC/Compucase is a popular choice for this price category because its units are affordable and perform decently. The secondary side uses a group-regulation scheme, which will give the PSU a hard time with our Haswell compliance test. Also, the components rectifying all of its rails are passive, which will reduce efficiency.
500B


600B


Same story as before lots of CapXon and Teapo caps used everywhere


Voltage Regulation is not great but it could be worse

500B


600B


12v rail ripple suppression is a little bit better on the 500B and 600B but not by much

500B

Reviews of the bronze rated units
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=351

http://www.techpowerup.com/reviews/EVGA/500B/
http://www.techpowerup.com/reviews/EVGA/600B/

At least the bronze rated units are better then the 80 plus rated units are.

So there you have it avoid these units if you are looking for one in your mid/high end gaming and/or overclocking PC, if you are making a cheap office/media or other low end non stressful PC they are okey but still not great.

All info and pictures came from techpowerup jonnyguru and the testing has been done by them so all credit goes to them not me.

Ew. No thank you EVGA.

I mean, I understand that these are designed with a certain budget target in mind.... but why when the Rosie Capstone, etc is a MUCH better unit for not that much more...?

Very well made thread as always! Information instead of don't buy this it's crap blah blah blah! And you're always willing to change your opinion if someone makes a valid point!

Good work Shilka wink.gif

Much like the CX series from corsair, these PSUs can't be interchanged watt for watt in enthusiast/performance computing builds with more highly regarded PSU options.

Odd that they chose pretty *decent* 105C rated SC series Teapo caps for the secondaries, but then went and used semi-garbage class 85C rated capXon LP series on the main filters. Huge bummer and that is apt to be a source of degrading power quality as the unit ages.

Yeah that didn't make sense to me either. Probably got a shipment of 100k of them for a good deal

Was thinking about a W.Y.S.N.B. thread for the Fractal Design Integra R2 and the Corsair CS next but i really dont know these threads have a way of going total FUBAR, and its not like i really like doing threads like this i just think everyone have a right to know what is not very good, its not like its hate or bashing on the units or brand.

Techpowerup review shows the main cap to beTeapo (400 V, 330 µF, 85°C). Does this change anything? It looks like it has better ripples then the 500B.

None of them are good but the bronze rated models are better then the lower white 80 plus rated models.
