New OCZ Power Supply!

[BUFF]

Iirc the TDP of the CPU alone in that system is 115W.
& it's nVidia that says that it needs 850W

nVidia also recommends 530W for 2x GPU SLi, however in reality 480W is overkill..
nVidia needs to account for inefficent PSUs, and thus going way over actual power consumption.

The only way you'd load a 700W PSU is by sticking a thin copper rod in the yellow wire of a molex connector and sticking it on the concrete outside..

Seriously.. you could power 2 heavily overclocked rigs from a 700W PSU. And try running them 24/7 and see how your energy bill looks at the end of the month/quater.

Nope. Try these guys on XS, running Dry Ice, pumping mad volts into there chip, with SLI 512mb, with insane volt mods, etc, etc, mods on mobo. Once you start all this mad cooling and volts, your average PSU is going to crash and burn.

There is a market for everything. They get cleaner, better overclocks with better PSU's, a a lot of them use the 650Watt beast from Silverstone.

I think its good news that mega PSU's are released with over-the-top wattage outputs, the PSU's i'm likely to need should come down in price as a result

nope, I seen TomsHardware using liquid nitrogen (nevermind dry ice) to overclock a P4 3.2Ghz to 5Ghz and the processor still only drew 180W. I don't care how insaine an overclocking project you will be working on, you will NEVER need a 1kW PSU.

Agreed, let the numpties buy PSU's for nob swinging that would power two of their computers, and us sane people will buy PSUs we really do need at a nice cheap price.

LOL you have no idea. 5Ghz on Ln2 is pathetic and thats toms hardware all over. Try 7Ghz, the extra speed, vcore needed and your using some serious power.

Like i said there is a market for everything. 99% of people won't need one, but that doesn't make it pointless.

if you can't except that, your problem. Guys on XS use 650+ PSU for a reason.

.... you will NEVER need a 1kW PSU...

I'm not a big power user myself (if you want a laugh look at my system), and at the moment 1kw does seem a little OTT, but as Bill found out never say 'never' ... doh I think I just contradicted myself ...

...Try 7Ghz, the extra speed, vcore needed and your using some serious power....

Ok, bear in mind that articale is nearly 2 years old, northbridges and ram weren't designed to take that kind of punishment, now the power drawn at 3.2Ghz is about 95W or so, if 5Ghz is 180W, then 7Ghz will only be about 270W, now thats assuming you will be cooling your CPU will liquid nitrogen, of course the number of people who would actually do that is miniscule, and the ammount of people who would use such a machine on a regulare basis is next to none, so the people to occasionally do so can easily just use a 2nd PSU to power everything else.

We're talking about reality here, and in reality the majority of people.. overclockers included, will not come close to the maximum load their PSUs are capiable of.

As time goes on fabrication processes of semi-conductors is constantly shrinking, and therefore drawing less power, so will anyone ever use a 1kW PSU?.. no, its just not practical to draw that level of power, especially these days as more and more people are running multipule computers in their home, and businesses don't want a £1m+ a year energy bill.

Well of course 500 W for the useful bit (processor etc) leaves another 500 W spare for the useless LED's, cold cathode tubes, illuminated fans and the rest of the bling!

Although I normally tend to stay out of these kinds of discussion:
"Yes you Do need one"
"No you Don't need one"
"Yes you Do need one"
... ad infinitum

Doesn't matter if there's a market for this or not right now. I'm using a 600W now cos my previous 480W just wasn't doing the job with my main rig, and I know that there are many more folks out there with PCs that blow mine away! 10 years ago when I started playing around with making my own PCs, 250W was an insane PSU for a desktop machine.

Semi-conductor fabrication may allow the manufacture of smaller gates, and therefore less power hungry silicon, ... ***BUT*** In the long term, reducing gate size means that you can stick more transistors onto a piece of silicon, which means that the resulting die size stays the same..... and eventually the TDP goes up. If this wasn't the case, we'd all still be using passive head sinks, or not at all. So, as long as some one is willing to pay the leccy bill, these things are going to sell.
