Is The Be Quite System Power 8 500w good for this system?

R5 1600 oc'd (Stock cooler)
Asus Strix Gtx 970
2 hdd's, 1 ssd?

Also is this a good pus?

 

[vapour]

970 tdp:145
1600 tdp: 65
consider serious overclocking and rest 50W
max draw < 350W
times 1.25 to leave some headroom, 450+ is more than enough
Be quite does not produce good psus...
Get [strike]Corsair CX550M[/strike] or Seasonic S12II/M12II 620 for budget psu, don't go cheap on psu, you may need to buy a new one soon. For better ones, Seasonic G/Focus Point or Corsair Rmx or EVGA supernovas GQ/G2/G3

Not really. That's mostly a mainstream PSU and you really want something better for what WAS a fairly high tiered card not long ago. That System power 8, and most of Be Quiet's units to be honest aside from maybe two or three high end models, are not terrible but not terribly good either.

You lose modular cabling, hybrid fan modes, pure performance and sacrifice a longer warranty, but, and it's a big one, these kinds of PSUs are perfectly serviceable units for a mainstream build.

We'd be happy to install something like the be quiet! System Power 8 600W into a mainstream build, and many system integrators will choose to do exactly that, but while these are fine for mainstream units they lack the reliability and quality you'd like to see in an enthusiast power supply.

What country are you in? What is your budget? Happy to help you select something that's not going to be a lemon.

I would not recommend the CXM units anymore. I just read this today. They are, apparently, even worse than the older CX units that generally reviewed well but failed prematurely due to the poor quality capacitors in them not holding up. The CXM units are apparently not even passing ATX specification testing.

The Corsair CX550M delivered power both under combined loading and crossloading, but it did not pass the combined and crossload testing in accordance with the ATX specification, so according to my evaluation methodology, it is not deserving of an evaluation. Upon first glance, the unit manages to deliver the voltage hold-up time of more than 10 ms. But because of a too lowly-rated bulk input capacitor, the power good signal does not, and upon further testing with a precise AC supply interruption, it is clear to me that the voltage doesn’t even stay in spec unless the hold-up time is much shorter. So short in fact that it may pose a risk of instability even if you actually use a UPS in conjunction with the power supply. Of course you can just buy a much higher-rated model, like the CX750M. But why do that? Why not just get a higher-end series with lower power for at a similar price point?

Another thing which seems very strange to me are the protections. Corsair only states that there is the OPP present. I found no such thing, the unit never reacted to overload and shut down when the voltage @+12 V fell under 9.5 V. This is more like a joke than protection to me. On the other hand I found the CX550M has OTP. It has also been reported there is in fact OCP working on the +3.3 and +5 V rails (most likely through the Anpec buck controller). So the advertised protections work at “meh” rate at best while there are other protections present which seem to work but are not advertised. This is kinda strange.

What I like about the series is that thanks to the DC-DC modules used, the regulation easily reaches the high-end class. It’s pretty much fantastic. Also the efficiency is really very good. However the ripple suppression hardly falls to within the margins of my mainstream requirements, and the -12V regulator has a difficult time keeping up with the high-speed fan connected to it. The thing is, there are huge differences in pricing. With discounts, the CXM is so damn cheap (and that includes shipping) in the US (I have seen it for 40 US dollars with shipping) that even with all corner-cutting, this unit still make a lot sense from a financial standpoint. For the money, there is simply nothing else that matches it. But here in Europe where the price is easily more than twice as high you just expect better performance. And some competing series (like the Cooler Master GM) have that. Corsair units perform great in the high-end, but it seems as though their mainstream still just doesn’t get things right.

@ darkbreeze

Wow, many people including several moderators on the forum told me CXM is good and better than seasonic evo... Good to know. Cross out CXM then....

 

[Darkbreeze]

Yes, and I am to blame on that as well. But when I find out otherwise I must needs change my opinion on whether to recommend a unit or not. I am in the process of passing this information along to others as well. Perhaps somebody will find another review with different results, but I cannot find one so I must trust, for now at least, that the information in that review is accurate and that these are units which, although perhaps fine for mainstream business machines, do not belong in any system with more stringent power demands.

It kind of sucks because these were really the only decent Haswell C state capable budget units available at fairly low prices, so now it's either use an older group regulated unit and turn off the C states, or pay more for a known quality unit.

 

[vapour]

budget and quality is opposite in most cases... Glad you find this out.

Not the same wattage (higher 650watt),but the same series,
review at Tom's here,
protections here seem to do well. Not defending Corsair,but did he (behemot) try another unit as well? (might get off topic btw)

Another thing which seems very strange to me are the protections. Corsair only states that there is the OPP present. I found no such thing, the unit never reacted to overload and shut down when the voltage @+12 V fell under 9.5 V. This is more like a joke than protection to me.

So the advertised protections work at “meh” rate at best while there are other protections present which seem to work but are not advertised. This is kinda strange.

Saw this mentioned at Corsair so why does he state that only opp is mentioned?

Over-voltage and over-power protection, under-voltage protection, and short circuit protection provide maximum safety to your critical system components

 

[npapa014]

is the corsair Tx series better?

 

[Vic 40]

The new TXM series ... yes they are.

You got a link to that? He specifically states in that article I linked to that despite what others have said, he found no evidence of it.

 

[Darkbreeze]

If I was going to buy a Corsair PSU, I would not be inclined to buy anything below an HXi unit, and since you can get a very good Seasonic or Super Flower built unit for less, I can't say that I see that happening anytime soon.

I was hoping for another review, that validates the indications on the product page, not the product page itself. Since the author indicates that other protections ARE present, and DID work, but that OPP did not work, it would seem that he is mostly not indicating that Corsair is wrong in a manner of saying something is there which is not, but rather saying something IS there which they did not indicate was. Probably Corsair has fixed this omission on their product page since that review was done but it still does not account for the fact that OPP failed whether it is there or not.

 

[Vic 40]

Between 550watt or 650watt are there no big differences than bulk cap,so in the Toms review they state that all works mostly fine with the 650watt version other than high ripple on the 5VSB rail,

So this doesn't become a lengthy discussion on somebody's thread.
