    Why?

    300W is more than enough.

    I hope that was a joke, for your sake and mine!? I wouldn't buy under 430W these days, and I'd have to go even further if I were getting SLi/Dual Core CPU.

    if you add up where your components use power, 300w is often more than enough.. how do you think laptops survive powering the display and all components with <120w (and, for that matter, how would shuttles survive on a 250w psu)..

    its just williemeasuring.

    Wouldn't the bill be the same as another PSU seeing as it would still be using the same power? (Assuming the same efficiency).

    Still, PSUs are a piece of hardware that I normally expect to last longer than the other components, except, possibly, for the case. Therefore, it's good to get a PSU that should last you while (although 1kW might be a bit over the top!)

    Yup. Unless you're running ****loads off it (which, at this rating, you really should be ) then it'll cost the same as any other PSU (assuming efficiency)

    The joke is the money you waste buying into this hype.

    Well, I don't see how really. Surely with a dual core processor, two gigabyte of DDR(II?), SLi setup etc, as well as hard drive(s), the power consumption (as well as PSU stability) easily goes sky high. Personally, I'd use about 3 HDDs, as well as 2 optical drives and numerous other external things plugged in. The external peripherals are 5W a piece (on average), so as I said, it all amounts fairly rapidly

    I'd go with something along the 400w line, maybe looking towards 480w and above if you are considering a setup alike to the one I detailed in the above paragraph.

    Though, the 1kW monster is tempting regardless of its excessiveness

    Like I write in almost all of my reviews that have a power consumption angle, I've yet to have my usual 420W workhorse be outclassed by any system I ask it to run. The last 'big' system it ran was SLI GTX 512s, FX-57. Piece of cake for it.

    There's no real way a current system is ever going to ask for more than 400W of input power, even loaded with disks.

    Further, a 300W unit, provided it's ATX2.0 and has plenty of +12V capacity, and is clean and stable, is more than enough for most modern PCs the masses are running.

    I explained it all in the PSU roundup I wrote for HEXUS.core, here. That 1000W supply is just madness for more than one or two contrived scenarios.

    Most switched mode PSUs ponly run at max eficiciency when they are operating near their rated output, so a 1Kw unit delivering 400 watts will be much less efficient than a 480w unit delivering the same power!

    what happened to the good old days of 230w PSU's? damn, time goes fast.

    I guess its true that msot systems will not chew up enuf to burden most PSUs today.. But the hype started with cheapo manufacturers that builds cheapo PSU with massive ratings but terrible specs. For a simple 2 HDD, 1 gaming gfx and a decent CPU.. you'll need like a 550W TRIPLE FAN (drum roll please*) QTEC to get it running stable.. Throw in abit of OC, and the volt ripples will send ur CPU straight to the grave and ur HDD to the corrupted dept.

    There are also certain batches from better, non-Qtec manufacturers that are just rubbish. Take the ULTRA-X Connect I bought 6 months back for example.. 500W rating, healthy amps on paper.. but it cant even keep my 2.7Ghz 3500+ Venice running properly with 4 HDD, 2 Opticals and one overclocked 6800GT during 100% CPU load. It does survive for an hour or so.. but after that, the system will either shut down automatically, or goes into a terminal freeze where the only solution is to pull the plug.. no the reset button and the 4 sec delay power button wont work as well.

    I guess these 1kW psu are meant for systems which will run loads almost 24/7. It makes pretty good sense for a system with 2 dual core cpu, 8GB of DDR400 and 4x140GB of 15k SCSI and 4x500GB storage.

    http://extreme.outervision.com/index.jsp (more upto date)

    According to outervision I will need 460w (assuming 80% psu utilisation) for the following

    opteron 146 @ 3ghz hopefully (so used FX57 value)
    2x 7800gtx (if I choose to buy another)
    2 sticks ram
    1 dvd rom
    1dvd/cd rw
    1 floppy
    2x sata hd
    1x ide hd
    3x 120mm led fans

    I bought a 480w tagan 18 months ago for my current system knowing that power consumption will go up. I think that a high quality psu with some headroom is one of the best investments you can make.

    I certainly would not want to run anything more than 80% of the psu wattage or 80% ampage on the 12v rail as manufacturers often quote their psu's peak power output which is unsustainable. Those that say you can get away with a 300w psu are not correct if running a modern a64 gaming rig!

    Incidentally the inquirer is quoting a site who have tested ati's x1900xt(x) cards

    "you need 450W with 30A for a single card while you need a minimum of 550W PSU providing 38A for two cards"

    http://www.theinquirer.net/?article=28611

    Not sure that I believe that cos that's huge Amps! As for 1k it's a bit like having 1k horsepower in a car - never gonna use it but you'll win in the bragging wars.

    With a price tag of ~500 bucks it'll cost something like 450 quid over here, that's insane for a PSU.

    What are "A"? It obviously cant be amps...so what it is?
