First post, I’ve been reading the forums for a while. Newegg had a sale and I ended up impulse buying the Zotac AMP! GeForce GTX 570.

When I was looking at the requirements it was saying that a 600 watt power supply is needed (The Zotac card is factory overclocked to 780 mhz and might have higher than stock voltage). I’ve currently got the Antec TruePower New TP-550 550W (link below). Some of my other specs are: i5 760 @ 3.6 with 1.3 vcore, 4 fans and, 3 hard drives.

I think I’m probably ok, as I’ve got a combined 45 amps on the 12v and the power supply is one of the ones made by Seasonic . Will the PSU actually be powerful enough for my machine?

Also I’ve been using a Geforce 460. Would I need to reinstall the Nvidia drivers (275.33) and/or Windows 7 when I put in the new video card?

You will be fine.Your PSU has plenty of power to power a single GTX570.The full system pwoer consumption with a GTX570 is right around 350watts.You could even use that GTX460 as a PhysX card with the GTX570.

I would suggest reinstalling the drivers for the GTX570,yes.

I think you will be fine with that power supply, the 600w recomendation is assuming worst case power supply quality. You don't have to reinstall Nvidia drivers, but there are newer ones out so you might as well.

Knowledge is POWAR !

As far as PSUs are concerned, be informed. Before you buy any PSU read accurate, objective PSU reviews at reputable sites such as www.jonnyguru.com or www.hardwaresecrets.com on the EXACT model PSU that you are interested in as some brands have good and poor quality PSUs.

You can also get an accurate rating of how much PSU power is required for your current or future system at the PSU calculator link below. Once you know the total PSU watts required then you need to confirm that the 12v rail has enough amps. to support your Vid card(s) and the rest of the PC system.

There are several websites that show the Vid card power consumption in watts. Divide the watts by 12 to determine the amps. required on the 12v rail(s). Add 15 amps for the rest of the PC on the 12v rail and you now know the Minimum total 12v rail amps required under full load. It's best to have at least 5-10 amps. reserve on the 12v rail available under full load so the PSU is not loaded to 100%.
It's also worth noting that people often misunderstand the 80% power rating. This is a rating of the PSU's energy efficiency not it's output. 80% plus PSUs use less grid power to produce the same PC power. If it's 80% Bronze, Silver or Gold the cost savings on electricity is pretty small between Bronze, Silver and Gold unless you are paying very high rates for electricity so any 80% rated quality PSU is fine even if not Gold. For those who leave their PC on 24/7 a quality 80% PSU is a good investment.
