How many watts? What one?

cheesemonkey · Oct 14, 2008, 09:48 PM

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.

Oct 14, 2008, 09:52 PM

350W at peak .

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

PennySavre · Oct 14, 2008, 11:33 PM

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.

Fastmix · Oct 15, 2008, 12:00 AM

Those components are not even out yet, what other people are saying is just a guess, my guess is 600/650 to play it safe.

mlee49 · Oct 15, 2008, 01:04 AM

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.

not saying that get a 350W PSU.

saying that the above system won't consume more than 350W .

So your say dont get the HX1000w because its 2 rails? i thought that was a good thing.

rampage · Oct 15, 2008, 11:40 AM

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

Here you go, Modular and single +12v rail. 700w though

Oct 15, 2008, 06:51 PM

get the xigmatek 650W Modular PSU and be done with it. Its the cheapest 80%+ Efficient Modular PSU

PCP&C 750w you wont have any issues its single rail to

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

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
