I have 2 questions right...

1. What do you think a core i7 cpu and a ASUS P6T with 3gb three way ddr3 will need in watts?
Including something like a 200 series gfx card and 2x 300gb HDDs.

I would of thought around 850w but im starting to think whether that's actually needed. maybe a 750w or lower?

2. After that, say this build came to be... what one would you pick? I originally thought the zalman 850hp (because its quiet and modular) but the HX1000w sounds dam good.

A power supply that is modular im talking about here.

Serious? A system like that would only need 350w?? Why the heck have people got 1000w PSUs? and why are companies bringing out PSUs like 1300w

One of the reasons to buy more power in a power supply than what you need is for either safety reason or for more headroom... like if I knew my system could work on a quality power supply of a certain wattage but it is cutting it close, I would go for something a bit better than that.

Cutting a little close there lol. Always have some head room it's better for the PSU in the long term. PSU weaken over time and even faster the hotter they get.

And i think you be better of getting a single rail PSU to make sure every thing gets the power it needs.

I checked this psu calculator out,
http://extreme.outervision.com/psucalculatorlite.jsp
I like Corsair, BFG, and PCP&C. Anything over 600W is good. If you add a second GTX 260 then a 750W will hold up.

btw the psu calculator is pretty accurate, so dont be surprised.

i would say 350 > 400 watts at LOAD (my rig uses 300 at LOAD gpu+cpu) so a good quality 600>700 watt psu would be fine... its all about the amps per rail and getting somthing with a bit of head room, i think of it a bit like a car engin you dont want to be reving it at 90% of its max when its sitting there doing nothing 50/60% is what i aim for

No, i am saying it is easier to overload one rail. With single rail you don't have to worry about that.

And no i am not saying it's a bad PSU either. Reason to not get it is you not needing that power, all though i guess it could save you from upgrading it later but that depends on how often you upgrade.

Should be more than you need + if you add stuff to it and should good stability.

All so take a look at the Silverstone, FSP and Corsair. I have found them all good for there mail in rebates all though Corsair i have had issue's with there's in the past but been able to get it resolved.

Take a read of this thread if you have not all ready

Its true put only at idle times. Idle and load have a serious gap in wattage. Probably a 600 watt is a minimum.

Been sweet for me :)..
Heheh, most people don't have any issue with Modular, the one modular PSU I got had major issues, but even if I hadn't I wouldn't pay extra for modular, just my opinion though :)

LOLs I recommended the TX750w from Corsair ... basically the same thing :laugh:
ummm not really

Screw modular, did it once, never again. I agree with cdawall. My PCP&C is an awesome PSU.
loving mine to it can handle anytihng i have thrown at it and its only the 500w (read 610w ;))

corsair<PCP&C
