When will PSUs hit 1KW?

If you want a cool quiet comp, don't use TECs. They put out a LOT of heat - you'll need a fan cooled radiator, and likely a fan cooled PSU for them. Plus they will cause a lot of heat to be dumped into the air.

like i said i have a powerfull watercooling setup ....


i have a cold water storage tank in my loft in it there is coils of copper pipe which goes along my loft via a central heating pump down my wall in 22mm pipe
just before it enters my pc it is still in 22 then drops to small cuttings of 15 mm copper then i have my watercooling loop which is done in tygon hose connecting onto that

my temps for a 2500 xp m at 2.6 hover around the 31 to 38 degrees mark

Looks like the answer to this is now (or soon at least)

Think of the leccy bill

I have ben reading up on the Mini-ITX motherboards with built in CPUs, with a laptop HDD and slimline CD drive (also from a laptop) one of these will consume about 25W, thats less than ur average lightblub!!!

They run at between 500Mhz and 1.3 Ghz, will run any windows or linux and do most things except gaming, perfect for home servers or overnight downloading machines.

Good website here: www.mini-itx.com or www.linitx.com (forum @ linitx.org)

I have choosen the parts i want, as i already have a broken donor laptop it will cost about £150 for everything except a case, but i'm not sure what to put it in, possibly a spiderman lunch box or somehow squeeze it in the spare psu space at the bottom of my stacker.

Any ideas, i want something origonal, but strong and sturdy enough to move around without it fallig part and very quite too.

You have to wonder what they think people need 1000W for in a computer. Even a tricked out SLI box is going to be under 500W.

Back to the original question - My Proliant 6500 has 2x 750W PSU's - they can in theory do 1.5KW allready.
That is a server thats about 7 years old......

So if its 7 years old its probably highly inefficient. I think that will be 1500W before you take effciency into account. Say its 50% efficient, thats down to 750W

I'm running my pc on a 300W, 2.26P4 (Fine at 2.8), radeon 9800Pro, 1 hard drive, 1 dvd, sound card etc

In gen the average PC is using 150 to 350 Watts depending on load.

PSU's consume 10-30 Watts internally under load depending on make / rating.

A PSU will draw the power needed for the PC plus its overheads, so as said earlier they will not use the full rating of the PSU but you will find with older PSU's that many are still limited by the supply rails and a high drain on one will dip the other so your never
going to get the absolute max, and hense why so many are moving to split rail supplies.

I cannot see the general home user needing a 1kw PSU bit of a swing and roundabouts, CPU's are drawing less watts but GFX seem to be rising I think rough requirements will stay the same, but certainly those buying into the full works super machines then yes requirements are increasing in like the server markets.

PC Power and cooling do a 850Watt PSU that's rated 950Watts peak power, close enough to the 1kw barrier but its a very long non STD PSU case and will not fit alot
of systems without getting the Dremel out

As for watercooling your PSU, I'd only do it if your skilled enough electrically and in the way's of watercooling.

I do not recommend joe normal opening up there PSU's, the cap's in them if you get your fingers in the wrong place and there not discharged will Kill You!!!!!!!!!! no joke.

As for watercooling a PSU its really only a matter of removing the heatsinks that the
power mosfets are bonded to and putting something in place that watercools those
mosfets, but it needs doing right, a poor bond and your gaining nothing except a
potentially dead PSU and you want to make sure you 100% leak free before even firing
up the PSU.

Minerial Oil cooling is seen as better as it has a low electrical conductivity and if a leak
does occur there are less issues of potential electric shocks, downside its is harder to cool the oil..
