My understanding of PSU's is that the PSU is capable of the burden of the wattage its rated at. It doesn't use 1200W if your system only requires 400W. I've upgraded my PSU without seeing massive increases in power usage because the PC doesnt use that much more Wattage than the previous CPu/GPU/Mobo etc that I installed.

To my knowledge the PSU does indeed not consume more energy then required by the system. Also it can deliver 100% of the rated wattage (and probably a bit more too). But continuous usage should not be more then 80% of the rated wattage (mostly because of efficiency and the lifetime of your PSU).

Hard to say, you'd have to measure it with a Kill-A-Watt.

As an estimate, use something in the 1/2 to 3/4 KWH ballpark, and calculate from there based on your utility rate.

In any event i7 Big Gun Battleships are like Ferrari's. If you have to ask how much it costs to run them, you can't afford it! ;-)

I know It's not cheap and I'm running a hyperfast Q9300(3.51GHz on air) souped up with a GTX295 supercharger, That RAC is from just one PC too currently, The bill for how much more will come before the 1st(My last electric bill was $45 last month), But getting My own P3 will not happen until July or when I've sold off enough to supply Me with about $42 to buy one with as the New Enermax Revolution 85+ psu just socked Me for $277.95 and that's with Free Shipping, Now If It will get here sooner than the 29th as a $40 rebate ends on the 31st of May. Of course I have an almost identical PC that needs a new case, psu and video card upgrade that will happen soon enough as It uses an old QX6700 B1(ES) cpu that runs at 3.52GHz on air. And If i7 cpus are Big Gun Battleships, Then My dirty pair are a pair of Big Gun Battlecruisers.

Good point about ship classification. I guess we could go with your suggestion, or classify i7's as Super Battleships. ;-)

Since this is kind of related.. I made my own kill-a-watt today and got 535 watts of total draw from my entire desk.

mobo: asus kfn5-d sli
cpu: 2x opteron 2222 SE (119w)
ram: 4x 1gb ddr2-667
GPU: 8800GT
hdds: 10 (various sizes..80-1tb)
display: 17" CRT
sound: 200-watt 2.2 channel shelf stereo system


I was actually surprised it was only 535 watts. I figured out from last month's power bill that my current rate is US$0.09211/kWh, so by extrapolation, my desk costs US$31.02/mo.

Well I chopped the good end of a bad extension cord off, grabbed a duplex receptacle and a spare single-gang electrical box, and clamp this around the black wire. Reads 4.45 amps. Change the meter over to VAC and stick the leads in both slots, and got 120.1. Volts * amps(current) = watts.. 120.1 * 4.45 = ~535 watts.

It's not pretty, and not exactly safe, but I'm used to working with live AC voltage, so it was fine for me.

Regarding the phase difference in AC circuits!

My Mac Pro tower has current and voltage with less than 1% phase difference. That means that volts time current gives true power. About same to the power phase into the lap top.

Big one has a dozen fans and dual large disk drives. And there are several drives that can be plugged in for external storage or moving big data sets around. I might even have more storage than I need!

Learned about AC power measurement way back when taking physics in the fifties.

How are you measuring the phase difference between current and voltage?

These days, the way to get a decent watt reading cheaply is to sample voltage and current simultaneously at a fairly high rate and compute the power from the set of readings. That allows for distinctly non-sinusoidal current waveforms where a simple phase difference reading is inadequate. IIRC the kill-a-watt takes around 1000 samples/second, plenty for the few digits of precision it displays.

Cosmic_Ocean's reading is of course VA rather than watts, but that's OK for an approximation since watts are always less than VA for anything other than a purely resistive load.

Part of my question to Cosmic_Ocean was to ask if/how he was taking power factor into account. Fast sampling seems like a pretty easy way, given all the different readings a Kill-A-Watt will return.

The other reason I asked: none of my power supplies have "good" power factors.

In other words, they all cost less to run than the VA rating would suggest.

Alright, I did some homework (thanks to google..) and have determined that without specific equipment, an accurate measurement is not possible, however, I still believe I am within 10% of 535 watts.

I think only the Alaska and Guam were Completed. A little bit over 30,000 Tones and 33 Knot Speed. The 12 Inch Guns were designed to counter German Pocket Battleships which had 11 Inch Guns. The Deutschland class Pocket Battleships were really just Heavy Cruisers (16,000 Tones) but with Small Battleship sized guns. Full Sized Battleships at the time had 14 to 16 Inch Guns. Light Cruisers of the time had 6 Inch and Heavy Cruisers had 8 Inch Guns. The Alaska class (American Pocket Battleships) were the size of World War 1 Battleships. They had thick enough armor that only a Full Sized Battleship could hurt them badly. Some called them Cruiser Destroyers.

You're part right and part not so right. Also they had no Torpedo protection what so ever and Yes You are right Only the Alaska and the Guam were completed to 100%, Whereas the Hawaii was only 84% complete when scrapped.

Alaska Class cruiser Wiki wrote:

The idea for a large cruiser class originated in the early 1930s, when the U.S. Navy wanted a counter to the "pocket battleships" (Deutschland class) that were being launched and commissioned by Germany. Though nothing resulted immediately, planning for ships that eventually evolved into the Alaska class began in the later 1930s after the deployment of Germany's Scharnhorst class and rumors that Japan was constructing a new battlecruiser class.[7][A 7] The Alaska class were intended to serve as "cruiser-killers", capable of seeking out and destroying these post-Treaty heavy cruisers. To facilitate their purpose, the class was given large guns of a new and expensive design, limited armor protection against 12-inch shells, and machinery capable of speeds of about 31–33 knots (36–38 mph, 58–61 km/h).

Do you think this will cost me monthly. It has a 1600 Watt PSU. Going to have seti Running 24/7 As soon as i get my GPU'S Cooled down.

Unless you plan to add 2 or 3 more GTX295 to the setup, the PSU is absolute overkill (?)

Yeah, From what I've read the 1050w psu I have has powered 4 GTX295 cards on an AMD motherboard, I saw that I think at bit-tech, But I did find another thread Here that mentions running four GTX295 video cards in one case and hacking a 178.13 driver and If done correctly, It works, Of course their using 2 psus and a custom case, So far I don't see any mention of the HAF 932 case of course.

Ok I'm Baaaaaaack and crunchin like a possessed Joker! Super isn't It?

I uninstalled the 850w psu and slowly installed the 1050w psu in the Coolermaster HAF 932 case, It went pretty smoothly for the most part, But there was one small problem, The Fan grill on the Enermax Revolution 85+ 1050w psu had to be removed as with the grill on the psu was forced higher in the case and so the 2 sets of screw holes would not line up at all, Remove the fan grill and all the holes line up and since the psu is facing down towards the bottom of the case this is not a real problem, Enermax could have recessed the fan grill better to work in cases like the HAF 932, But this does not matter to Me.

Oh and the BFG GTX 295 is crunching on all cylinders as is the iQ9300 quad core cpu, So My RAC should start going back up soon enough.

Oh and I have some Good News and Bad News, 1. Good, 2. Bad.

1. The 1050w psu has enough cables for 3 more GTX295 cards.
2. The HAF 932 case will not allow more than 3 GTX295 or any more than 3 of any type of GTX 200 or newer series video cards in the case as the case follows ATX standards and has only 7 backplane slots. :(

Oh and one more bad thing about the Enermax Revolution 85+ 1050w psu, The Molex connectors were hard to get to plugin to any of the drives that I have, The OCZ Molex connectors are better as they just push on, Whereas with the Enermax I had to fiddle with them somewhat.

Of course too late I found a case that will hold 4 GTX295 cards, It's made by Thermaltake and It's Here. It has 10 card slots instead of 7 like most cases have.



Here's a review of the case at ThinkComputers of the Thermaltake ARMOR+ VH6000BWS Full Tower Case.

And this BigBruin review says the VH6000BWS has foam air filters and shows them too.
