Hey guys, so I'm going to build my PC real soon, and here are my specs, not sure how much Wattage do I need here. please help :) 


1. Cooler Master Hyper 212 Plus 120mm Sleeve CPU Cooler ( probably going to add another 120mm fan for the other side, since it only came with 1 fan ).

2. Western Digital Caviar Black 1 TB SATA III 7200 RPM 64 MB Cache Internal Desktop Hard Drive Bulk/OEM - WD1002FAEX

3. Kingston Hyper X X1 Black Series 8GB DDR3 1600 (PC3 12800) 240-Pin SDRAM Dual Channel Kit XMP LE

4. Gigabyte Intel Z68 ATX DDR3 2133 LGA 1155 Motherboards GA-Z68X-UD3H-B3

5. Lite-On LightScribe 24X SATA DVD+/-RW Dual Layer Drive IHAS424-98

6. Intel Core i7-2600K Processor 3.4GHz 8 MB Cache Socket LGA1155 (will be overclocked to at least 4Ghz-4.4Ghz)

7. EVGA Nvidia Geforce GTX 580 1536mb ( the official EVGA site said needs at least 600W PSU to have this running on the rig ).

the case is :
Cooler Master HAF ATX Mid Tower Case, RC-922M-KKN1-GP (Black)
the case alone has 200x30mm fan x 2 included.

Currently I'm thinking of :
1. PC Power and Cooling Silencer 760w High Performance.

So the question is, do I need bigger PSU than the one I state above?
thanks

lol not yet, but according to this http://www.tomshardware.com/forum/314712-28-please-read... and another link inside that thread says the GTX 580 will need at least 600-626W on max power, so lets say 600 divided by 12 is 50.

then 50 + 15 + 5 amps. so it needs 70 amps, and it says my PSU delivers +12VDC @ 74A Single Rail Design.

Im a noob in choosing PSU thing lol..

so what do you think?

The EVGA site is recommending a 600W PSU to run a system with a GTX 580. It is not saying that a GTX 580 would consume 600W by itself, as no card on earth draws anywhere near that much.

These would be better for a single GTX 580:
Seasonic X-650 80Plus Gold Modular $110
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Corsair 750TXV2 80Plus Bronze $105 ($15 rebate)
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

If you ever want to SLI then you would need a minimum of 850W.

SLI needs at least 2 GPU right? so I think im not going for the SLI here since its a single GTX580 ?

I'd buy twin 560 Ti's (900MHz) which will beat that 580 by about 40% for about $60 less than the single 580. That would require at least a 750 watter . Single 580 could I'd still go with a 750......Using this w/ 15% capacitor aging and your specs, I got:

http://extreme.outervision.com/PSUEngine

(1) 580 627 watts (CPU Oc'd to 4/8 Ghz, no OC on vid card) ... I'd use 750
(2) 580 838 watts (CPU Oc'd to 4/8 Ghz, no OC on vid card) ... I'd use 950 - 100
(2) 560 680 watts (CPU Oc'd to 4/8 Ghz, no OC on vid card) .... I'd use an 850 watter since ya prolly gonna fo to 1000Mhz

1st tier:

Antec SG / CP* series
Corsair AX/HX series
Seasonic X series

* requires compatible case for CP

2nd Tier:

Antec HCP/HCG/TPNew series
Corsair TX Series
XFX Core Edition


As to the rest ....

-Why Z68 ..... you gonna take advantage of anything here ? If not P67 an option.

-Why 2600k ..... You gonna be doing video editing, CAD, big databases or anything that uses hyperthreading ? If not 2500k will do same thing and run cooler.

-Hyper 212 is a great budget cooler but ya other parts are all high end ..... High end would warrant a 1st tier product. CM V6 GT is the best performer but loud .... Thermaltake Silver Arrow is right behind it and dead quiet...... Hyper 612 is right behind the Arrow but not on store shelves yet.

the 580 from EVGA said it is superclocked right? i think i will stick to the PC power and cooling 760w here.

yes i will do some gaming and video editing.

what is the main difference between z68 and p67? really, im not quite get it :( (

I might change the hyper 212 to antec kuhler 620 h2o liquid cooler ( thats quite decent right? )

thanks!

I chose the Z68 because im going to use the integrated graphic card first, then save up some money probably 1 month later after i purchase this rig, i will get the GTX 580..

not going to spend boom! 1500 bucks gone.. haha
