June 8, 201213 yr What relevance does this have to power draw from the wall while on idle? As you get lower on power draw the efficiency drops. Getting low with a 550W means you have to get under 100W of power consumpion (roghly 20% of nominal power) to start losing efficiency, which is unlikely even on idle. Getting low with a 1000W means getting under 200W, which may well happen on the other hand. This means that on idle, with a PSU that is too big for your system, you will have a bigger power draw. Just like piston engines have a efficiency range, in a very similar way PSUs have their best spot in terms of power output/power consumption. http://www.anandtech.com/show/2624/3 Mateusz Kapusta
June 9, 201213 yr What relevance does this have to power draw from the wall while on idle? More importantly, what relevance does this have to my FSX performance?
June 9, 201213 yr More importantly, what relevance does this have to my FSX performance? Nothing, but it would save you money (both when you buy, and when you pay your energy bill). Mateusz Kapusta
June 9, 201213 yr More importantly, what relevance does this have to my FSX performance? If he has enough money to buy an 1800euro system, I think he can spend a few extra bucks a year with a larger PSU.
June 9, 201213 yr If he has enough money to buy an 1800euro system, I think he can spend a few extra bucks a year with a larger PSU. I think you misunderstand me; I'm with you, buy as big a PSU as the budget can accommodate. I think buying small is foolish, b/c it could limit you one day. When that day comes, you're no longer saving money, because you're buying the bigger one in addition to the smaller one you've already purchased. I've had a rig that wasn't very upgradeable, and I don't ever want to be in that situation again, so I buy my parts to be future proof, and that's what I would recommend to the OP. A kilowatt+ is doing just fine in my rig.
June 9, 201213 yr I'll take signal quality over ridiculously overpowered units any day of the week. I mean it's ok to have some headroom, but getting 3 times more W than you need makes no sense to me. 750 - 850W are more than enough for any SLI, and with the new Kepler lineup being so power efficient, there's no way you'll ever need more than that
June 9, 201213 yr 750 - 850W are more than enough for any SLI, and with the new Kepler lineup being so power efficient, there's no way you'll ever need more than that Hehe... I went way overkill with my Corsair AX850. Although, if someday I get 4 GTX480s, that will really put it to the ultimate test. :LMAO:
June 9, 201213 yr Hehe... I went way overkill with my Corsair AX850. Although, if someday I get 4 GTX480s, that will really put it to the ultimate test. :LMAO: Yeah, if you somehow find a way to hook up 4 GPU's, (or even 3) to your motherboard
June 10, 201213 yr Yeah, if you somehow find a way to hook up 4 GPU's, (or even 3) to your motherboard DIMM slots will work with graphics cards right!? :LMAO: :LMAO: :LMAO:
June 10, 201213 yr DIMM slots will work with graphics cards right!? :LMAO: :LMAO: :LMAO: LOL 850w may not be as much am overkill as you think. PSU's can degrade up to 20%/yr depending on the quality of the capacitors and hours of service. I average about 2.5 yrs on a PSU before it dies, no matter which manufacture. In fact, Ive lost more Corsairs than any other brand but, in their defense, I have used more of them also,

June 10, 201213 yr Do capacitors age? Certainly. All electronic components (except perhaps inductors and transformers) age. One of the PSU calculators allows 10% a year PSU degradation under normal usage and 20% - 30% per year with 24/7 computer usage. This does not pass the "Does this make sense?" test to me. Proofs how "Little" people here think they know! Specially the one that comments on every post to run up their post numbers only!

Proofs how "Little" people here think they know! Specially the one that comments on every post to run up their post numbers only! Please Rendi, at least read the link you posted. Doesn't help your case too much you know. Fact is that one should get quality over quantity. Build quality and signal quality and forget about capacitor aging. Good PSU's are actually already overprovisioned and can handle more than what's in the sticker. The HX850 for instance, has been tested at 1000W+ but was rated at 850W just so that it falls under the 80+ silver certification. Actually it caould have been 80+ gold certified but Corsair decided not to because it fell short a few % in the hot box Again, please read that link you googled and tell me if you agree with the opinions there including: I just do not worry about capacitor aging. Interesting notation on that. I myself am a gamer and i've been using my Corsair TX 750 watt PSU for about 3 years now, and it still runs great. I've had a great deal of graphics crads installed on it, ranging from SLi 9600 gt to 9800 GX2 to SLI GTX 460 (current) and it's still toughing out. 10% a year is just crazy. The calculators aren't predictive — they aren't even MEANT to be. They're built to account for worst-case scenarios, so of course their degradation numbers are pessimistic. Look at some of the very old audio file A class amps, like Mcintosh. ten year and older from this company is still fine and expensive in some cases High end equipment that i required over 15 years still works.. receivers, stand alone amps, even no name PSU for PCS that i retired because its so old... It still runsThat capacitor aging is for marketing purposes only. Its a question if the vendor installed reliable capacitors or not. I just purchase a good reliable brand w/ great reviews PSU. To conclude i don't use the capacitor aging... I use my engineering judgement to decide the brand, capacity of my PSU for my PC .
