The Ultimate Dream Computer

Here's my first go at a rudimentary PSU volume graph in Openoffice. Far more models to follow.

For reference, a system with an overclocked QX9650, 4GB of RAM, two HDDs and two HD4870X2s in it sits at around 620-650W on this graph (it's DC load, not AC input)

 

you should switch the X and Y axis, where did you get thes enumebrs from? and the 430w BQ! DPP? i havent heard of that, the lowest is the 450W

 

It's the only BeQuiet! PSU silentpcreview have reviewed unfortunately. I'm hoping they'll do a 600-700 watt variant at some stage, they reviewed a 700W Nesteq this week.

I know the axes are an odd way round, but I chose this method as when you're after a quiet PC, I tend to think of it as not 'how loud will it be with this much power' but 'how much power can I get out before it gets too loud' and that essentially means you target the decibel figure, the PSU that achieves the most watts at that decibel figure wins. For the average joe it might seem odd, but said average joe probably doesn't care about noise that much. What is clear though is just how astonishing the ZM1000-HP is. Very shortly I will be adding the absurdly overpriced, but spectacularly quiet Enermax Modu82 unit.
When I say overpriced, I mean that the 625W variant SPCR reviewed is only £9 less than Zalman's 850W unit, which is believed to be as quiet as its 1KW partner, based on its performance in the endpcnoise gamer rig.

I wonder why they didn't include thermaltake. Mine is quiet. BUt then again, what do I know. My computer has 8 noctuna fans and a 1200W PSU, and sits in my room where I sleep.

 

Thermaltake stuff isn't typically that quiet...

 

why would anyone need a 1200 watt PSU lol

 

lol Zoso, don't bring it up again haha. I guess if you totally wanna max out with tri SLI and stuff you might need it.

 

hummm ok lol. my Thermaltake 750 watt is overkill, let alone 1200 watts

 

Yeah but you're not exactly using a top of the line video card or a crap load of drives lol.

 

Heh, well a 1200W PSU is overkill in almost every circumstance, a 750W PSU is overkill in a lare proportion of circumstances, even a 450W PSU is technically overkill for a large number of PCs out there, depends on your usage.

 

I guess you could have a tri SLI with like 10 harddrives and a crap loaf of fans and lots of USB stuff connected.

 

Or you could have it hooked up to a 600W RMS amplifier.

Well ZoSoIV, you are running an old video card...older than the 8800 series, also none of components are OC'd. Your RAM is shit too.

My RAM requires 1.7 Volts to run at 1600MHz, but I have at 1.9.

You also definitely missed out on the 1200W PSU discussion.

 

Lol, be a bit careful about how you hook that up though, I wouldn't want anywhere near that much power running through one molex connector, or chain. I'd suggest you make some way of powering the system with two parallel lanes of connectors.

 

Well I actually read the current that the particular 12 volt line can take, and I'll just put a fuse block on that line, I'll probably shoot lower than the ~22A or so it says though.

 

Even so though, that's per rail, not necessarily per block of connectors. There's only one 12V wire on a block usually, and 20A is a lot of current through one of those thin wires. They can and do melt!

 

lol

TheftAuto I would like to think we are getting along better. But his Ram is NOT crap. In fact I wouldn't be surprised if his computer was faster than yours. His Ram is just as good performance wise as yours.

 

Sorry, what? I don't get the relevance of that post... You might also want to remove the s word...
