And we have first boot. Yay!

slight overkill but nothing wrong with that.

overkill is better than the reverse.

anyone who thinks a case is an important piece needs considerable counseling.
most people POST outside the case at first and could run there forever.

nice cases are fine but they are just personal accessories for ease of use or looks or other environmental preferences outside of actual performance.

Too much capacity? Has anyone here even done any accurate (not just rough guestimations) calculations about what this system would draw and what percentage of the PSUs capacity he wants it to operate within? Nope. [and now, if I didn't add this line, a couple of you would get out your calculators and waste your time trying to calculate a more accurate figure to prove me wrong, but I know as well as anyone else that 850 watts is overkill. Does it matter? No it does not. Voltage regulation and reliability is what's important. No one does everything 100% right.]

No need to calculate, it's already been done... many times. 850W is a waste, plain and simple (sorry for dragging this on OP, you got a PSU to power your machine, that is what matters in the end, but if this guy isn't shut up now he'll likely become a problem in other threads). You are making a fool of yourself now with your name calling and poor grammar. I suggest we end this now and you admit you are wrong, before I do get into the details and shut you up with no way for you to babble yourself out. You are in over your head here, just leave it be...

Just for a few details, PSU efficiency lays somewhere in dead center of capacity. So that PSU would be most efficient at ~425W. His computer draws less than 200W idle, and will draw under 400W load, so the best efficiency would be found in the 650W-750W range, depending on what tasks he performs most. This, by the way, doesn't even factor in price, it factors capacity. There is no question $170 was way to much to spend on a power supply, be it an 850W, or a 400W...

Again, sorry OP, I didn't mean to have this drag out. It must seem like I'm trying to bash your system into the dirt, but it is a solid system, and you should enjoy it.

Not everyone has those problems. I'd bet a lot of people who "have" the problem just dunno what they are doing.

ROFL

?? Do you have something to say or are you just gonna sit there like a special needs kid?

Thanks for the replies all (and the honesty)!

OK, so next build I'll not splurge so much on the CPU and PSU. Hopefully what I have will mean I don't have to replace them for a while at least. I'll have to run some synthetic benchmarks that are amenable to HT to make myself feel better at the wasted £80

I'm quite interested in the points made about the power supply. I was under the impression that the system would, at load, draw something like...

Overclocked i7 2600K ~100W
2x 5850 Toxic ~ 350W
Misc other ~ 50W
+10% for inefficiency ~50W
Total ~550W

I added 50% to this figure so that I would be running nearer the efficiency peak and some notion/assumption I pulled from my ass that running near capacity on the PSU would be detrimental to it's health. Are my power consumption estimates above wildly off the mark (as BTRY B 529th FA BN suggested) or is my latter assumption just plain wrong? OR both of the above!

You are probably pretty close. I bought my PSU with the mind that running it in ~40-60% utilization is most ideal for several reasons. But, most importantly, running your PSU in it's most efficient range is a sign of intelligence and maturity.

You have never overclocked, or lived somewhere where the weather is nice, have you?

Case selection can be literally critical. It is very important that a case facilitate ability to maintain (eg, vacuum/clean) the internal components (fans, heatsinks).
My computer was built as an R&D system with one of its uses being to fix/repair other computers. The ability to quick access components and connectors for swapping components in and out (HDD imaging, formatting, diagnosing and data recovery) is absolutely essential. Further, it is light weight and therefore easily relocatable. I have never regretted purchasing my Lian Li all aluminum tool-less case. (Most other cases for this purpose were useless or actually just horrible/unworkable.)

You seem like a reasonable guy who can take honest criticism (contrary to what some posters in this thread may think), so I will elaborate.

Your numbers look fine, but you overlooked idle efficiency. Your system will spend far more time at idle (like 95% for a typical desktop) than at load. Yes, the PSU will be most efficient between 40-70% load, but the efficiency at 80% is much better than the efficiency at 20%.

If you had asked before you bought, I would have recommended a reasonable 650W PSU (550 + 15%) because the 650W gives you plenty of safety margin but is much more efficient at idle than a 850W would be. Mot to mention that it would cost a lot less!

^I would also add that you will never practically hit 100% utilization either, which means you're probably not even hitting that peak efficiency mark (unless you run OCCT and Furmark together or something).

It should be obvious why this is the case. Whenever you're playing a game, either the cpu or the gpu will be the bottleneck. You simply won't ever see every single component of the computer with power consumption maximized under real-life use.

Thanks for all the input guys, I now know more for next time. Few centuries of progress and eventually I might not be that dumb. Here's to the future!

 

[Davidh373]

You weren't dumb, you made common mistakes and they were overestimating for things which is much better than underestimating. Especially with PSUs. At least a PSU that provides more than you need will power your build, while one that doesn't supply enough wont.

Also, I don't see double toxics being a horrible thing, but they just cost WAAAY too much imo.

It's fine. Dumb would be buying a crappy-quality overspeced 1kW PSU.

 

[jibberegg]

The double toxics were a funny one actually. I managed to get a really good deal for one (only £15 over stock 5850). While i was pleased with one, it was unfortunately doa. I complained and asked for a replacement... They sent me two. Very very pleased! And very very surprised!

The only enlightenment you were near was me enlightening other people how wrong and retarded you were...

Anyway, yeah, the only reason I even commented in this thread was because I accidentally clicked on it from the home menu and this happened to be more of a well-chosen system than average in this forum ():thumbsup:

Trolls aren't right most of the time... if I agreed with most people, I'd also be as ignorant as them. It's a scientific fact, humans get more stupider in groups. LOOK IT UP.

That logic doesn't prove you aren't a troll nor does it prove you were right.

Don't you mean "more stupider"?

wow... Guess that shows how smart you are... I've got a tip for you. Next time you're trying to prove how "smart" you are, proofread... I'm pretty sure we've been over how horrendous your grammar is...

Agreed.
