16gs Ram at 1866mhz(Cooler installed)
Mobo: ASUS P8Z68 Deluxe - LGA 1155
Only have 3 140mm Fans and 1 240mm Fan plugged in( dont know if psu would be able to handle the other 3 140MM fans)
1 blu ray drive installed
1 64g Samsumg SSD installed for OS
2tb WD green 7200rpm not installed, againt, not sure if the PSU will be able to handle it.

You should be able to power your system with a CM 600W, with a single card config.

For SLI I suggest you CORSAIR Professional Series HX1050 1050W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular Power Supply http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Ok, thanks, just powered it, with the 600 watts psu while i wait for the new one, feel like im cutting kinda close lol, the 12va rails are rated at 18a each, for a total of only 36A, see the card pulling in 32A at stock settings on load.

The Cooler will have no discernable effect on your PSU.

Ya can check what nVidia feels is good enough here:

The AX1200 is a much better PSU than the HX1050 .....just about all of the HX series are great, getting 10.0 jonnyguru performance ratings....the 1050 however is the sole exception getting a rather pedestrian 8.5.

HX1050 (8.5) - http://www.jonnyguru.com/modules.php?name=NDReviews&op=...
AX1200 (10.0) http://www.jonnyguru.com/modules.php?name=NDReviews&op=...

I doubt that you even have 36a, the max is not usually as much as the sum of the two rails. The data plate should give you the max combined amps or wattage for +12v.
It is recommended that a 600w psu with 42a be used for a GTX580.

But, the GTX580 will not draw full power untill it is under full load, so I think you are ok if you do not push it. If the power becomes insufficient, I do not think there will be any damage. Iw ould expect the card to downclock or shut down first.

I would go with the ENERMAX Platimax EPM1200EWT 1200W- They have a platinum rating for a reason, quality.

Ended up purchasing this PSU: http://www.amazon.com/gp/product/B003PJ6QVU/ref=oh_o00_...

Anyways, trying the pc with the 600w PSU, i saw the card pull 66a on a Full load, when the 2 12v rails are rated at 18A each, 2 connected to it for a total of 36A...

What problems could that cause? >.>

The GTX580 needs a 6 pin connector, and 8 pin connector plus the slot for power. the 6 pin connector can deliver 75w max, the 8 pin 150w, and the slot 75w for a total of 300w, or a max draw of 36a. Regardless, I would limit 3d graphics usage until you install your new psu.

With its +12 Volt continuous current rating of 100 Amps it's far more than you need so it will handle any overclocking of the CPU and GPU you can throw at it.

Ok, and one last question I have a 20A ciircuit for my Room, would that be enough for the PC, 24inch led monitor, 50 inch led tv, 5.1 audio system(low specc, 1000w), 1 router, modem, and consoles?

As i don't know if it was my circuit or the first 1200w PSU that came faulty.

As long as you're not running all of those toys at once at maximum power the 20 Amp circuit breaker shouldn't trip on you.

The Thermaltake TR2 RX 1200W (TRX-1200M) is made by HEC/Compucase. Not really known for making high quality power supplies.

The only Thermaltake power supplies that are worthy of consideration are the Toughpower Series models.

The new Corsair PSU that you're getting should be of much higher quality and better electrical performance.

20a should be plenty.

That is standard for a house circuit. Remember that 20a is for 120volts which is 2400watts. Your pc will only use as much as it needs.
