Building New Gaming PC



Ok Guys Really need some good advice from Game Machine Builders. I am going to Build an Extreme System Using either the new Intel Mother Board From asus which will be comming out in March of 2010 or the AMD Asus Crosshair III Formula.. I am also getting the Radeon HD 5800 series Video card when it hits the market. Only the start of my Build, My Question to any and all Serious Gamers-Game Comp Builders is What is the BEST, Tightest Power Supply that I will get an Overwhelming yey to? Both the items mentioned will not be out till Next month but I am in the process of getting all other components.. I'm Looking to Build a Rocket for my Games :D Please Advise. I will also be using Solid State Drives.

BFG Tech EX-1200watts looks good for your extreme top notch rig. But if you SLI or Cross fire use gold or silver certified psu for energy efficiency.
Antec TPQ-1200 1200W silver certified
Rosewill BRONZE series RBR1000-M 1000W said it would run @40 but it depends on your chasis.
the only 2000Watt psu i could find(I don't think anybody ever needs this...)The Ultra X3 Modular 2000W
keep in mind that I hybrid SLI 2 5750 and overclocked amd phenom ii 965 to 4.0ghz and used 800watt psu with out any problem. (still too much) so i'm plenning to switch to 6-700watts psu... but if you still want to get 1000+ psu go for it.



Thank you for your response... I will definately look into that... Still tossed on the Motherboard and most likely will go with the ATI Radeon™ HD 5970 for a Video Card... Got to look into a Case as well :)

Corsair HX1000 is spoogeworthy :)
It will go well over 1000 watt AFAIK. I got the 850watt version and its nice :)

I hate to beak it to you but the Radeon 5800 series has already hit the market, and NVidia's Fermi has been announced to hit the market on March 26th.

Also the 5970 is a very nice card, but make sure you have a big enough case cause its massive.

2 x 5850's would give similar performance to a 5970 but cost a lot less.

+1 for the Enermax Revolution85

Great PSU

I would go for HD 5970 over Crossfired HD 5870 if money isn't an issue. Less hassle with older games that don't like crossfire. (might be a non-issue for you)
Hold on!

Please list your pc components so we can make valid recommendations. For example how many video cards do you plan to install. In your posts you only mention one video card. Obviously a 1500 watt power supply is overkill for an overclocked system with one video card.

Here are the official power requirements for the ATI Radeon™ HD 5970 video card.

ATI Radeon™ HD5970 System Requirements:

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard

650 Watt or greater power supply with one 75 watt, 6-pin and one 150 watt, 8-pin PCI Express® power connectors

850 Watt power supply with two 75 watt 6-pin, and two 150 watt, 8-pin, PCI Express connectors for ATI CrossFireX™ technology in dual mode

The power supply recommendations are for an entire pc system.

My suggestion:

Processor: Intel i7 Extreme Edition with compatible motherboard.
Graphic card: ATI Raedon HD 5970 (maybe corssfire 2 of them)
RAM: Corsair 12Gb
PSU: Corsair HX 1000
Case: Antec 1200

I want to see this RIG.... :D :D
Can't see anything requiring more than 850 watts. For comparison purposes , the list below contains performance ratings (10 scale) at / prices as per newegg on 02/21/2010 and ones w/ double asterisks (**) made it onto's Editor's Choice List indicating outstanding electrical and acoustical perofrmance:

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

Antec TruePower Quattro (TPQ-850) - 9.5 ($150)
Corsair TX850 - 9.5 ($140)
Seasonic M12D 850W - 9.5 (NLA) **
NorthQ Giant Connector 850W - 9.5 (NFS)
Etasis ET850 - 9.5 (NLA)
Silverstone Zeus ST85ZF - 9.5 (NLA)

Enermax Revolution 85+ 850W - 9.0 ($250)

Thrmaltake Toughpower XT 850W - 8.5 ($216)
OCZ Z Series 850W - 8.5 ($200)

NorthQ Black Magic Flex 850W - 8.0 (NFS)
Coolmax CTG-850 - 8.0 (NFS)

SilverStone Decathlon DA850 - 7.5 ($230)
Enermax Galaxy DXX 850W EGX850EWL - 7.5 (NFS)

SilverStone Strider ST85F - 7.0

Silverstone Element ST85EF 850W - 6.0

NFS - Not For Sale / NLA = No Longer Available

The CP-850 paired with the Antec 1200 saves you $84 ....CP-850 is a match electronically (both get a 10.0 performance rating at but the CP is quieter.
