Sufficient Power

[THERESONATOR]

I'm looking to buy a new system consisting roughly of these parts:

Antec Nine Hundred
DFI LANParty UT 790FX
AMD Phenom 9700
2x Asus ATI Radeon EAH3870-G-HTDI-512M HD 3870 512MB GDDR4 DVI HDMI PCI Express 2.0
Corsair 4GB (4 x 1024MB) PC6400 Dual Channel DDR (QUAD2X4096-6400C5DHX) XMS2 C5 DHX
2x Western Digital Raptor 150GB WD1500ADFD 16MB Cache 10,000RPM (running RAID 0)
Thermaltake CL-W0121 Bigwater 760i Liquid Cooling System
Akasa AK-188-BL Cold Cathode 12'' Dual Pack - Blue
Viewsonic VP2030b 20'' LCD Monitor

That's roughly it. Now how much power would I need? Ideally the PSU has a blue light in it! Just for effect really. But doesn't matter that much. I've been looking at the Kingwin 800w[See Here]. Notice its modular. The blue light's nice. But modular is really necessary for me. Is that too much? Alternatively I could go with the Antec P190 case and use their 2 PSU system, one of which is hardly being used and the other is being used heavily (doesnt make sense). Who prefers the Nine Hundred over the P190? Anyway. What do you reckon is the best modular PSU for this system? I know its pretty expensive, but I don't care. I want the best that ATI and AMD have, and the best of what's out there! So price aint a factor. Although cheaper is nice. Performance first, price second, in order of priority.

All advice appreciated.

I would go with something from corsair or pc power and cooling. A corsair HX620 or a PCP&P silencer 610 will probably be sufficient for you, unless that water cooling system draws alot of power. I'm not really sure about Kingwin, but I would guess that they're a solid brand. Wait for a reply from someone else for a different opinion before commiting.

Thanks. Here's a link for that decent liquid cooling system I'm after, it should say something about power on the spec, I just aint technically minded enough to understand it!

Bigwater 760i

Also, is the Corsair modular?

Doesn't Look It

Enhanced modular flexible cables enable easier cable routing and increased airflow in the system.

900>P190
THe quality of those power supplies have been mediocr at best
Many people are having problems with the poer supply and the extra cost added on the the p190 for them are a waste of money

Go with the P190, personally, I got a CM Stacker 830 and I have never been happier


If performance is your main concern, buy 2x eVGA 8800 gt , if you can't affordd it, get one
eVGA's step up policy allows you to pay the difference to 9800 gtx when it comes out

The easiest way to figure out your power consumption is by using a power supply calculator. The best one, IMHO, is here.

 

[THERESONATOR]

Thanks. As for getting two 8800s, I'm afraid my heart is now set against it. Believe me, I was going to get the best quad core intel and a couple of the best 8800GTXs (512mb) around all sitting on the new Asus X48, but with what you get for your money here in the UK in terms of performance the quadAMD/crossfire ATI sitting on a DFI 790FX I reckon is the way to go. The HD3870s have outperformed the nVidia cards in some game benchmarks anyway, and thats without the overclocking.

 

[THERESONATOR]

From what I've read, the max overclock the Phenom 9900 can do is from 2.6Ghz to just over 3Ghz with a Vcore increase from 1.25v to 1.44v. Taking this into account using that PSU Calculator, total power req'd is just over 1kW! EEK! I wonder what its like when you OC the crossfire graphics cards and memory?

I suppose I should ask:

Best modular PCI-E 2.0 Xfire 1200w PSU?

So where did you get 620w from?

 

[MarcVenice]

Bullshit, for a phenom 9900 and 2 HD3870's a good 600w unit will suffice, depending on other hardware, 700w might be needed. This is not using a calculator, coz those are bullshit most of the time anyways. It's just using numbers from reviews, where they measure the powerdraw from several components quite accurately, add those up, and you more or less know what kind of PSU you need to run all those components.

 

[mageslayer]

I agree, there are quite a few 650-850 watt quality psu from name brands like corsair and cooler master

Jump on one of those, and you should be set

 

[BladeVenom]

I saw a review for the Kingwin not to long ago, reviews conclusions. It doesn't sound like it would be my first choice.

If you hurry the fluff up, you can grab 1 of these for a measly $50 !!! http://www.pcclub.com/product_...ls.cfm?itemno=A6296671

Thats a very good unit, high qaulity, but not modular, for just $50. It was out of stock, it's in stock again, so better hurry if you want one. It will easily power a qaud and 2 HD3870's.
