Required PSU?

I'm currently deciding on the parts I'd like to put in my computer. Only thing to decide now is the power supply. After Reading the sticky post up there I concluded I needed a 650W power supply. But I'd like to make sure I'm correct.

Here's the computer parts that will be in the tower.

Intel Core i7 Quad I7-930 2.8GHz LGA1366 8MB 4.80GT/S
ASUS P6T X58 ATX LGA1366 DDR3 LGA1366 3PCI-E16 PCI-E1 2PCI CrossFire SLI SATA2 GBLAN Motherboard
ASUS ENGTX470/2DI/1280MD5
Corsair XMS3 Dominator TR3X6G1600C8D 6GB DDR3 3X2GB DDR3-1600 CL 8-8-8-24 Core i7 Memory Kit
SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive
DVD Drive
DVD Writer


1. Is a 650W enought for what I stated up there?
2. Considering I will eventually add another GTX470 in SLI, 6gb RAM I should be going for a 800W PSU?
3. And If I overclock my CPU, RAM and Video card, does this make a difference when choosing the PSU?
4. If you have any recommanded PSU that arent too pricy to fullfill Question 2 answer, I'd be glad to hear it.


Thank

The 470 is pretty power hungry (as well as hot and loud) - any reason not to go with an ATI card?

Another suggestion - If I were buying new parts, I would get a board with SATA 6Gbs and USB 3.0 - there are plenty of boards by Asus and Gigabyte to choose.

For the PSU, check here:

I'm thinking that the 650 may not be enough for a dual-GPU system like that

I always got problems with my previous ATI cards. And since I tried Nvidia one I'v been very happy with them. Plus the 470 is a good card for it's price in comparison of target ATI.

Which Asus board support SATA 6gbs and USB 3.0? By the way what is the point to buy a SATA 6gbs board. Does the HD I selected will use that extra available speed?

Thank for the psu calculator. Will take a good look.

Got to agree with huron here, the ati cards are superior. It took nvidia twice as many transistors and 150% more electricity to slightly nudge ahead (they're in trouble there).
Don't know what you're previous ati cards were, are they from this century?
As for you're actual question, no a 650 watt is not enough for the system your describing, not with sli using 470's. If it was a top quality brand it might be enough with cross fire say (2) 5850's.
The issue is you want to run the power supply in a comfort zone 40-60 % for maximum power efficency. Of course using 470's does away with any thought of efficiency anyway.
Since you appear to need to buy a psu anyway and are looking at dual cards with a system overclock you might want to look in the 800-1000watt range for a quality brand hopefully on sale, $100. The savings in electic costs will pay for itself in a year to two years with a bronze unit. good luck.

I'm not closed to switch over a ATI card. What would be a good card (Or dual card) for around 350 bucks?

As for the PSU, what is a gold, silver or bronze psu?

Btw if someone could answer my SATA question, I'm still wondering :) 
May 5, 2010 10:55:45 PM

The ASUS PX58D is one for sure. The ASUS PX58D is one for sure, though a little expensive.

About the Gold, Silver and Bronze certification - they are measured at 20% load, 50% load, and 100% load and if they meet certain efficiency standards at each of these levels, then they earn the certification. It's escaping me right now what they are exactly...sorry.

Check out 80plus.org for some more info it interested.

I'd go ATI right now if I was buying and would probably look at the 5850 if I were you.
May 5, 2010 11:07:29 PM

You need a power supply with some head room.I know some one who is selling a Silverstone 1000w for a good price.they just need a site to sell it from.

Corsair 850tx is going for 109.99 at newegg and a 5850 will run you about 309, from what I've seen (2)5770 in crossfire will cost about the same as a 5850 but will draw alittle more power. The 5850 is sufficient all by itself and leaves the opportunity later to add another when price comes down in a year.
The real question is are you going to run any graffics that are as demanding as the 5850 can handle as 300 is alot to spend on just a graphics card no matter how good it is.
Leaves me thinking about the old saying you only live once, but a graphics card only lives about 2 years maybe 3 before something better is required.
You can check powersupply reviews at hardware secrets.com for reliable reviews, don't just buy one without knowing.

I'm sure I'll be able to fully use the 5850 by playing games. (That's a gaming computer).

After reading some review, the Corsair 850tx will be just fine for my needs.

Now gotta decide if I'm ready to let my love for Nvidia go away for that 5850. But after I saw the noise and heat and power hungry card, guess I've got not much choice.

Btw who are the good manufacturer of Radeon cards? Sadly it seems that Asus doens't make this one.

You really seem to stuck on Asus for everything for some reason.. Anyway, Sapphire makes some quality cards and are a trusted Ati only partner.. Plus their vapor-x and toxic cards are wonderful.. Give a look to them..

For twin GFX cards, you'll want a high quality 850 watter if you want to maintain stable voltages for a great overclock.

For comparison purposes , the list below contains performance ratings (10 scale) at jonnyguru.com / prices as per newegg on 02/21/2010 and ones w/ double asterisks (**) made it onto silentpcreview.com's Editor's Choice List meaning they excelled at both electronic and acoustic performance:

Antec SG-850 - 10.0 ($220) **
Antec CP-850 - 10.0 ($110) ** Requires compatible Antec case)
XFX 850W Black Edition 10.0 ($185)
Corsair HX850 850W - 10.0 ($180)

Though the price just shot up $30, this is still a super buy:

Asus offered me quality speed and realiability for every single computer I built. Yes I love them. After reading reviews I see they still offer what I want.

Thank for the great infos. Btw I read about the P6X58D-E, it says it has no optional fan. Does it mean I cannot plug an additional fan on my case?
May 6, 2010 4:54:52 PM

No, you can buy a fan controller.

Antec P183 Black Aluminum / Steel / Plastic ATX Mid Tower Computer Case looks very nice. I see there is talk about GTX 470 Case certified designed to prevent heat inside. Does this one fits the job?

Well if you plan on adding a second video card, and that too a GTX 470, in future then you better take one with high airflow coz those babies can get seriouslly hot.. I think an antec 902 would be good though i hear they suffer from pretty bad cable management.. I guess a good modular PSU (like a corsair HX 750 which I'll recommend for your build also) can take care of that.. A CM Sniper would be a better choice on that regards although some might argue that for its price, one can get a full tower case like the CM HAF 932

P.S. - I've no grudge with your asus love.. I too know they make some very fine quality stuff..

Two Fermi's?

There are currently five pc cases on Nvidia's official list of recommended cases that can accomodate the large video cards and provide optimal cooling (more will be added as they get tested and certified):

•Cooler Master’s HAF 932
•Cooler Master’s CM 690
•Cooler Master’s Stacker
•SilverStone’s Raven RV02
•Thermaltake’s Element V

I have the Coolermaster HAF 932. Ventilation, airflow, and cooling are excellent. It is one of the top gaming cases.

Tom's Hardware recently published an article about using multiple GTX 480's. Here's what they had to say about case selection:

http://www.tomshardware.com/reviews/geforce-gtx-480-3-w...

I recommend you read the entire article.
May 7, 2010 5:16:23 PM

Yeah thank guys. Did read the article Jonnny and it was rather interesting. I will get the HAF 932. I Like the design and it pretty nice and look ventilated enought.

For the PSU I will get the CMPSU-850TX. Reviews are great, silver certification.

Emperus : Didn't take it personally don't worry. I'm a "fanboy" but not a blind fanboy at least :) .

Big Thanks.
