jeffunit,
You mention the power supply efficiency, as not being all that great... I don’t disagree with you, as I don't know what the other power supplies efficiency is at various loads. But for those who may not know as much about power supplies, your comments may be misleading.
First it is important to distinguish a few things about power supply ratings. If the efficiency stated by a company is simply a single percentage or says “upto xx%”, then it is really not telling you the whole story. Efficiency is not a singular figure, rather it is more like a curve. It starts out low at very low loads, as the load increases, so does the efficiency, then toward peak loads it falls off again. So just as important (if not more important) than the peak is how flat the curve is.
That said, it is more reasonable to say that this psu is 80 PLUS, and upto 85%, since the curve never dips below 80% and 85% is the peak, not 80%. Really the 80Plus certifications tell you the most about the efficiency curve. The certifications are based on efficiency ratings at 20%, 50% and 100% loads. In order to obtain the various certifications the psu must achieve these levels.
| Certification | 20% Load | 50% Load | 100% Load |
| 80 PLUS | 80% | 80% | 80% |
| 80 PLUS Bronze | 82% | 85% | 82% |
| 80 PLUS Silver | 85% | 88% | 85% |
| 80 PLUS Gold | 87% | 90% | 87% |
Seeing the reported rating for all three loads actually gives you even better information since as in this case, the psu is considerably better than the bare minimum required for 80 PLUS and is only lacking a 2% efficiency at 20% load to be certified as an 80 PLUS Bronze.
The point is that this power supply is really quite nice. But certainly there are others that are better. But before you can honestly know if a psu is better than this one, you need more than a single figure.
That said, I generally agree with the comments here including your other comment on ECC. This rig is not very impressive overall... and I wouldn’t seriously consider this a workstation class system that is worth the bucks it costs. About the only parts I think are worth having are the case and psu. Again, not that either of these are the best, but they are pretty good. But that’s it. Considering all of the limitations of this board, I don’t care how well made and how stable it is, its just not worth it.
WyomingKnott,
To respond to some of your comments/questions, this is really not the rig for you. You will pay more than it is worth if you are just a “tinkerer” or “enthusiast”. Even if it were a better motherboard at a better price, true workstation class hardware cost considerably more than other systems, and the added stability you are referring to, might not be quite the same thing as the stability of a workstation system. Think of it like this. If you were going to leave your system running for a week or more solid and the whole time, it was going to be rendering a video or an image and even very small memory errors over the course of that span could wreak havoc on your work, then that is a workstation. If on the other hand, you plan to use your computer for various tasks, maybe home video editing, and some personal photo editing, etc, and you expect to have it running maybe 4 hours a day, or even if you planned to use it for working and expected to use it for 8 or 9 hours a day. But don’t want to be hassled by an occasional hiccup, and even given that you would like to play with some RAID, you could buy or build a much more suitable system for considerably less money that you would be very happy with.
With ECC, again, I personally think it is probably unnecessary for your case. There is certainly nothing wrong with ECC, but I doubt if you would notice a difference. I honestly believe that most stability issues for the average enthusiast are the result of several factors:
1) Cheap Parts – Just because you don’t need an Intel or other brand server motherboard doesn’t mean that you should settle for a PCChips or no name motherboard. Buy good quality parts.
2) Components running out of spec – Just because you are not overclocking does not mean that your components are running within their specifications. For example a cheap or faulty power supply might cause voltage to sag in places. Even if you have a great power supply and a great motherboard, you’re voltages may not be perfectly within spec. It is very possible to confirm voltages and adjust them via the BIOS to get them to run closer to spec, or even slightly over if necessary. Most components have an acceptable under and over voltage range. It is better to be slightly over voltage but within the acceptable range, than to be under voltage outside of the acceptable range.
3) Excessive heat – Most people do not give much consideration to the heat generated in their system. They are quick to notice fan noise, but are slow to think about the impact of a slow moving or stopped fan, a system clogged with dust and dirt, or of inadequate cooling to begin with. It’s a delicate game of balance to avoid excessive noise and provide sufficient cooling. This doesn’t mean that you have to run water cooling, etc. (even though those can be very quiet and very efficient). But if you plan to run RAID you may want to just give up on the idea of a quiet system anyway. Even if not, do not sacrifice cooling for a quiet system. Don’t be afraid to switch to aftermarket heatsink/fan combos, but read up on them, good reviews/ratings and make sure they allow enough clearance for your motherboard, case, other components, etc. use enough case fans and arrange them for equal flow or positive pressure, not negative. (that means equal volume of air moving in and out or more air moving in than out) fans have different speeds, sizes and blade pitch with all add up to different volumes of air. So use CFM to arrange and not number of fans or size of fans. Also do not have fans blowing in close to fans blowing out. Chances are the hot air will be redrawn in.
4) Software – Viruses, adware, bloatware, crappy applications that run all of the time and have memory leaks, etc… Software is just as likely to be your problem as hardware is. Perform a fresh install of a stable OS (64-bit if you can), install anti-virus and anti-adware, keep them running and keep them upto date. Install only the applications you need. If you want a “scratch pad pc” then use a separate computer or a virtual computer. Don’t download and install crap on your system you want to be stable. Don’t install something that a friend gave you. Don’t surf questionable sites from your system, in fact don’t surf at all, use a separate computer or virtual machine to surf the web. Reboot regularly. Learn about processes and programs that automatically run. Download and learn to use “AutoRuns” from Microsoft (previously SysInternals). And when you first do a fresh install record everything set to automatically run, get rid of things that are running that you can. And keep that list handy… once a month compare the current state to the list and remove new crap that has set itself to autorun.
Think of it like this, lets say you are not getting a new computer but a new car. First, if you only look at price and you buy a brand new car for $9,000, (yes it can be done), you are probably not going to expect much of it or be very happy with it. Now if you move up the scale and look at a nice car that is $35,000 or another one that is $60,000. Ok, so either one could be a very nice car. You really may like the $60,000 car, it may hug the road a little tighter, it may have a quicker take off, but if you drive it around for a while (few years), you constantly over rev the engine, you never change the oil, never change the plugs or filters, never perform any maintenance on it. After a short while, it starts running hot, but you ignore it and keep driving it hard anyway, a warning bell starts to ding so you cut the wire, you start to develop an oil leak that you also ignore, its not really going to matter if you got the $35,000 car or the $60,000 car, because either one of them would be running like crap by now… it doesn’t matter what kind of system you buy if you don’t maintain it. Once you make sure you are going to maintain it, then don’t buy the cheapest piece of crap you can, but that doesn’t mean you need to buy a Rolls Royce either.
If you really want to play with RAID then you are not going to be disappointed in a hardware RAID card. I don’t mean a card that gives you enough connections to run software RAID on a bunch of drives either. It needs to be a RAID controller that actually has a processor on it. Again, you don’t have to buy a $1000 card, but don’t buy a $100 or $50 card and expect it to perform like a true hardware RAID controller. Also there are a lot of factors in running RAID, like the drives. Don’t setup a RAID and cripple it with 7200 RPM SATA drives. Yet again, if you cant get 8 x 15,000 RPM SAS drives then that’s ok, but don’t buy standard home consumer hard drives that you spent $50 bucks each for. Finally if you are going to setup a RAID 5 for storage that is great, but don’t run a single drive for the OS, etc. Run 2 drives in RAID 1 (mirrored) if you cant do that (i.e. you are only going to use 4 drives, etc) then run RAID 10 or 5 on all drives as one large virtual disk and then when partitioning carve it up into System and Data partitions.
Well, I guess now that I have a book written, I should go…
