is 550 W enough?

post #1 of 20
Thread Starter 
I just assembled my first pc, and the power supply I chose is bothering the hell out of me. I used http://extreme.outervision.com/PSUEngine to calculate the parts i went with and give me recommended of at least 425W with 3 fans and 5 usb devices,

than i used Aus calculator http://support.asus.com/powersupply.aspx and with the same set up and the parts below it suggested 600 W minimum.

Than i read over time that psu looses efficiency over years and to add (20%-30% on bottom of extreme website)

So should i return the 550 and get a 650w just in case or am i being paranoid ?

I booted without a problem and this pc is a monster I was ruining bastion and hot pursuit on high and didn't even budge compered to my old pc was about to explode..

thank you for any suggestions!

EDT: also really happy with the performance so far so no overclocking will be done on CPU

For that system the PSU you picked is fine. You picked a really high quality PSU. If you decide to go SLI you will have to consider a new one but right now you're fine smile.gif

With the 550w Rosewill, you could easily Sli two 660 ti cards. So you have plenty of psu power.

Was it the Capstone, which is actually a very good quality Super Flower, or was it one of their other lines, which are sometimes crap? Rosewill puts their names on a lot of PSUs, so just going by Rosewill doesn't help much.

Ya, you obviously have no idea what you're talking about...

OP: Your psu is very nice. You could throw another 660ti in there easy!
