Can get a thermaltake 1500W for pretty cheap so considering that atm. Heard good things about that being silent. Can anyone recommend anything else ?

You don't need 1k+W on your power supply. Hope this helps :)

Maybe YOU dont with your low end setup, but try running my rig with less than a 1kw PSU....

How do you know he isnt using it in a folding rig or a dual cpu/quad gpu setup etc?

@ OP: I would not reccomend the TaganPipe Rock series for quietness, mine is silent until it gets to about 600w load, then it becomes silly noisy andis the loudest part of my PC which ****es me off now as I have replaced everything else for silence :(, the Corsair HX520w I have is always silent though, so I would assume other high specced corsairs would be wqually as quiet.

Corsair HX 1000w, ive seen one in use and its every bit as quiet as the HX850w i use myself. Also having owned a Thermaltake toughpower 750w, i found it to be a fair bit louder than the corsair.

just noticed your sig, what do you do to warrant like 20TB worth of space :P :O

its only like 12.38 once formatted and losing space to raid 5 parity etc :P

At the moment, I have just bought the 5 2tb drives so its sitting unused, just bought it before I ran out of space (down to 250gb free) on my other drives, and because I finally worked out how I could another 5 drives into my case if I got external dvd drive and fan splitter cables etc.

While I would like to say its all useful stuff like disc images of systems that I support for companies and all the business data etc, that takes up a marginal amount. Its mainly films, a 1080p blu ray rip is pretty large when you want to have a huge number of films lol.

Also, I dont like deleting things, and I like to have all my steam games installed, which now totals 1TB in itself :/stupid sales, havent even got time to play them all.

edit: forgot about the NAS, thats was mainly just backup of raid arrays on other systems, and is to give me a backup solution that isnt in my PC, incase everything inthat randomly fries or something. The original offsite backup to Carbonite (uploading on ADSL MAX 8mb) was fun......

I think he's probably glad that his laptop doesn't need a 1kw PSU!? :rolleyes:

yea, I know, didn't think about it being a laptop when I posted, and then cba to edit it after I re read his sig. But the point stands, just because he doesn't use 1kw doesn't mean others wont be. Along with the fact that most PSU's say that "normal" usage is around 50% load, and thats where they are the quietest as the fan ahsnt had to ramp up.

a 1kw laptop would be amusing, you might get to run superPI before your battery ran out.
 
You choose a PSU wattage based on the machine load. The best way is to use a power meter to see what your machine is using, and adjust that to include the PSU efficiency. Not an easy calculation and only for the very thorough. Alternatively just estimate it based on the components.

With the silent pro gold for example http://www.coolermaster.com/product.php?product_id=6663 the efficiency peaks at about 91.5% for a load of just under 50%. If your machine draws 300W you would go for the 600W PSU. If your machine draws 600W you would choose the 1200W, for maximum efficiency.

In fact, with that PSU it would be better to choose one too small, so the load was over 50%, than choose one too big and have the load under 50%. Strange but true.

His sentiment was correct, if not poorly put. 99% of people who post "spec me" threads on here don't need 1kW PSUs, I think that he was generalising a little ;)

Normal usage is around 50% load, but most people run their computer at a lot less than full load on all components all of the time. So it's better that your psu is power optimised for the lower load which is receives for most of the time in my opinion.
 
Specs:
i7 920 @ 4.2 ghz HT vcore @ 1.45v QPI @ 1.6v
Rampage 2 extreme
2000mhz 6gb dominator
2 D5 pumps
4870 x2 (OC'd to 800/3600)
DVD drive
etc..

Antec site said 980w :s But I plan to upgrade to a new GPU soon, either the 580, 6990, or 590, they will be watercooled and most likely oc'd too.

Pretty concerned as atm im using a coolermaster realpower pro 1kw that I've had for 2 years. Had to replace the fan as it got too noisy. Pretty PO'd as the reviews I read at the time said it was really silent.

I heard complaints about the ax1200 on forums about it being very noisy also seen a lot being RMA'd. Same with the coolermaster pro gold.

Currently got my eye on the nexus rx 1.1 or thermaltake toughpower 1500W. Anyone have experiences with these ? Power supply atm is the loudest thing in my system hence why a silent psu is absolutely vital.

Your system will pull max of 500w - 550w ~ from the mains, I use a i7 with a 580 (in sig) this pulls 500w with Prime & Furmark running. Also I had a 480 GTX this pulled 615w from the mains.

You will be fine with a 750w PSU.
