Future proof PSU

Unfortunately there's no such thing as future proof in this game!
I'd start at about the 600W decent PSUs and work upwards based on whether you want modular etc.
Of course, if you wan't as much power as possible, look at the 1KW supplies, but I think these would be overkill for what you state up there, there's few machines that genuinely require that much power.

are there the same as the xigmatek ones ?
I have a OCZ stealthXtreme 600w at the moment but dont know if its going to cut it with all of the about but with one GTX280 and the 8800GT....
What you guys think ?
http://www.overclockers.co.uk/showp...at=1088&name=Antec Signature Premium 850W PSU
I think that's your best bet.
I think you're gonna be struggling, those OCZ's aren't great to begin with. Mo chance on earth when you add a 2nd 280.
I'd be buying a new PSU iof i were you.
"Big psu's will tend to be noiser as well as using more power at low loads"
That's absolute rubbish. It depends entirely on the quality of the PSU in question, the better the PSU the quieter and the more efficient it is. Size has nothing to do with it.
You can't "oversize" a PSU either, a PSU will supply only what is needed.
Efficiency is prett much nonsense in PSU's anyway, we're only talking a few %, over a year the saving would be tiny, but it's green, it's a nice selling point, so it's hyped-up.
Nothing wrong with a more efficent PSU of course! But let's not pretend it will save the planet or kepp your leccy bill down.
I'm sorry, you're wrong.
Every PSU has a sweet spot - the point at which it's most efficient. Generally they're about 50% load (that's not accurate for all). If you have a 1200W PSU and you use 300W at load and 200W at idle then you'll not be getting much efficiency from it.
Over the course of 2-4 years life of a PSU that can account for half the cost of it.
It's simple maths, but it confuses a lot of people.
Let me explain.
70% efficiency - 30% wasted. Running at 400W load that's 120W constant waste.
85% efficiency - 15% wasted. Running at 400W load that's 60W constant waste.
Leccy is what, 10p per kWh?
So that's 60W wasted or 0.06kWH, at 10p is £0.006 per hour. £0.144 per day, £1.008 per week, £52.416 per year, and £157.248 for the 3 year life of the PSU.
Of course 70% against 85% is an unlikely comparison. But the figures show there's money in it.

Yep, I did say it was an unlikely comparison. The point was to show that it comes out in £. Even if it's half of what I said that's £75, or if it's quarter it's £40 quid. That's something.
You've just said 15'% is unlikely, it's probably nearer 5%. The savings are pretty minimal and certianly not worth worrying about. Also if you're buying a top quality PSU to begin with it really doesnlt matter at all, as they are all very effieceint theese days.
Maybe a few years ago, it meant more than it does now. I can see what you'ree saying but i donlt think it's that big a saving to make it a serious consideration with a PSU, certainly not over build quality, or how much "future proofing" you have bjuilt-in, or the modualr option if that floats your boat.
I'm sure there's value in it, but how measurable it is to the individual user is unknowable to be honest, and unpredictable pre-ownership.
