Looking for a future-proof psu in case I want to upgrade my gpu anytime (planning on running Battlefield 3 on an 8800 gtx). Gaming comes 2nd to sound production.

So I'm looking for the best bang for my buck (preferably under $100). It also needs to be modular, I hate not having options and would hate even more to limit my gpu choices if I decide to go that route.

Thanks

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.

Well, I assume you want a PSU to last 10 years, so you want it realiable and silent.

Go with Cooler master silent pro. They have a 600W for $100, altough I recomend gettting the 700W version, just to be safe. And never worry about PSU again. BTW, its modular
