How much do I need in a PSU?

post #1 of 4
Thread Starter 
I've been looking over PSUs, and I know the last computer I had - the PSU gave me a lot of trouble because I went with a cheap brand. Now that I am building a new computer, I was curious what you guys would recommend as far how much juice will I need? I've been looking at Corsair's line because they are known to be very reliable, but I am open to suggestions. Right now don't intend to SLI, just keep a single card. Got everything, just waiting to decide on a good PSU. I was thinking 600 or so would cut, but not 100% sure.

You need a quality 400-450w PSU.
Refer to both of these helpful resources:
PSU Calculator: http://www.overclock.net/power-suppl...alculator.html
Suggested PSU's list: http://www.overclock.net/power-suppl...-supplies.html

May I suggest this great deal? It's on the suggested PSU's list. http://www.newegg.com/Product/Produc...82E16817182202
430 watts, $39.99 - $10.00 = $29.99 with FREE shipping.
$10 off w/ promo code EMCKCHB33, limited offer

This is good if you don't want to SLI. If you SLI two GTX 560 Ti's you'd need around 650 watts.
