1000W power supplies
I don't know if I'm impressed or disgusted that some people need a power supply like this.

I just bought a 430W power supply for my home "server" and that's only because the motherboard manufacturer recommends it. I don't even think I need it.

I was just playing around with the eXtreme Power Supply Calculator, and I kinda failed at rising over 800W without exceeding the limits of what's reasonable (With the calculator, I can stack in 120 HDDs, 45 optical drives, 140 fans, 20 PCI-e cards, 8 sticks of DDR2 and 4 quad core processors, but in reality that's just not possible.)
I think 7 out of 10 1000W PSUs that are sold seperately (not in an XPS or whatever) are sold to people thinking "Meh, I have a shitload of money, let me just get 'the best' of everything, I don't care if it's redundant.", then there's 2 that think that their PC actually needs all that power, and 1 more that actually needs it.

Yeah... pretty much every PSU calculator out there on the 'net is useless. Thankfully some are less useless than others and hence are only 30-50% off base rather than 100% or more.Sylph-DS wrote:I was just playing around with the eXtreme Power Supply Calculator,
Probably not even that many who actually need it. +12v rail draw kills most people these days, often because they're still using old ATX12V 1.x units or they're using $35 "OMG 500W!!!!" specials that can't handle 500W for more than a few seconds... they panic and think they must need more than 500W when their box only draws 275W from the wall.I think 7 out of 10 1000W PSUs that are sold seperately (not in an XPS or whatever) are sold to people thinking "Meh, I have a shitload of money, let me just get 'the best' of everything, I don't care if it's redundant.", then there's 2 that think that their PC actually needs all that power, and 1 more that actually needs it.

Well, at least it makes the "low" wattage psus a little cheaper... I think every home should have a wattage readout LCD on every outlet. That way, people could understand how much each of their appliances are using up. I still find it amazing that some people have dozens of 100W light bulbs in their homes. We could seriously do much better than this, but, eh.. fuck it.
I would agree with that.jaldridge6 wrote:Well, at least it makes the "low" wattage psus a little cheaper... I think every home should have a wattage readout LCD on every outlet.

I have a 9W bulb in my room and I tend to turn that off when I'm sitting at my computer (I have a CRT which I can't really afford to replace at the moment).
Actually being able to see the power draw of appliances would open peoples eyes.
There are some nice product concepts based on this, but none have really taken off on a large scale.

So you're sitting in the dark in front of the monitor? Not a good idea. You may save a few dollars on your electricity bill only to spend hundreds if not thousands on your eye care bills in the future.jammin wrote: I have a 9W bulb in my room and I tend to turn that off when I'm sitting at my computer (I have a CRT which I can't really afford to replace at the moment).
Re: 1000W power supplies
Just let ppl buy what they want to buy....Why would you be "impressed or disgusted" becouse somebody bought big PSU ? Or is maybe envy becouse these guys can actually afford this sort of gear ? Sound like it to me.valnar wrote:I don't know if I'm impressed or disgusted that some people need a power supply like this.

Wow. Where did that from? I take it you don't have humor in Sweden?Redzo wrote: Just let ppl buy what they want to buy....Why would you be "impressed or disgusted" becouse somebody bought big PSU ? Or is maybe envy becouse these guys can actually afford this sort of gear ? Sound like it to me.

I should have mentioned that I also have a lamp (LED), so I don't actually sit in the dark.JazzJackRabbit wrote:So you're sitting in the dark in front of the monitor? Not a good idea.

The main light tends to cause glare on the screen as well, which is also bad for your eyes.
The amount of time a lot of people spend infront of a computer (myself included) is concerning.
I do try and look after my vision and hearing
There's a good article on real power consumption and 1000/1200 Watts power supply @ BeHardware.

Yes! I really need a 1000 Watts power supply!Before moving on, let’s touch on the arguments of the above two manufacturers. With Enermax, there was a configuration with a consumption of 933 watts. Based on a Quad Opteron system, it had the specificity of having no less than a mere 24 hard drives.
Thermaltake went even farther, offering a configuration that consumed 1105.5 watts. The only problem was that only 605.5 watts were used by the PC, the other 500 was for an amplifier and speakers. These are peripherals that aren’t linked to the PC power supply.

While 1K may be over the top, if you want some headroom with SLI'd 8800 GTX cards as I will, you have to go pretty high - consider the results from the aforementioned testing on such a loaded system at Be Hardware:
Time for SPCR to test a few SLI-capable 750+ watt PSUs!
So even a 700 watt PSU isn't too safe - I'd want at least a 750. And Nvidia themselves on their approved list don't go any lower than 750. Also you need to consider the 12V load - a staggering 484 volts on the 12V rail -- 41 amps. Unfortunately that eliminates every SPCR tested PSU - I was hoping I could go with the Seasonic 700w modular recently tested but I guess not.Consumption doubled compared to the previous configuration, because we are at 384.7 watts in stand by and 687.6 watts in load.

"The power source actually supplies 567.6 watts, of which 85.3% are on the +12V, efficiency being 82.6%. So this configuration justifies the purchase of a 600-650 watt supply, and even one a little higher if you like to have a little room"

Its very hard to get a PC to draw over 500W DC, 8800GTX SLi, QX6700 @ 3.7Ghz, 4GB ram, 2 HDDs, 1 DVD, 5 120mm fans and a pump use less than 510W. I would imagine HD2900XT Xfire would use less than 550W.
A quality 600W+ PSU will handle a 510-550W load easily. A 550W+ load it would handle but get very noisey.
Low Quality Power Supplys usually rate their Wattage/Amperage at temperatures below 25C. Maybe a water cooled PSU could reach those temps but most PSUs with a 500W+ load would be around 40C+. As the temperature of the PSU rises the total Wattage/Amperage and Effiency lowers.
nVidia know that a quality 600W PSU can power SLi easily, but they also know a cheap generic 600W PSU can't. Thes why they have the 750W/12v-41amp minimum.
A quality 1KW PSU could almost power 2 Highend gaming rigs or 3 Midrange gaming rigs. A 2KW rig is for idiots ( maybe not if your using pelts ). At most a quality <800W will power any sane rig with ease.
24 Hard Drives = 312W, that is if they all spin up to full speed at the same time ( which is unlikely unless its a very large RAID array ). After the spin up they would only use 192W and 120W when they are idling. ( That would be using Seagates 7200.10 drives )
