So I looked on Newegg's PSU calculator to figure out power needed, and it doesn't have options for like having an SSD and HDD both. Or case lights, fans, CPU coolers, etc. I was wondering this because I wanted to see if this PSU http://www.newegg.com/Product/Produc...82E16817151088 would be enough to power my setup. Here is what i have:
-i5 3570k (going to over clock)
-XFX 7970 DD
-Corsair SSD 120g
-WD Caviar Black 1TB
-Xigmatech Dark Knight II Cpu Cooler
-CM Storm Trooper Case (8 fans on this case)
-16g Gskill Ripjaws DDR3 1600
The calculator says I need 483 w PSU, but like I said, there aren't options for having both SSD and HDD, case fans, etc.
I just got that one too for my 3570K & 7950 setup. I initially got a 550W non-modular PSU (XFX) but decided to upgrade after only a month. More than enough power and I got it for future expansion (Crossfire and whatnot).
That PSU is more than enough. Good quality PSUs, especially with this one, tend to run very efficient, and being a Seasonic brand, I'd trust it without any second thoughts. Even if you were to overclock your i5-3570k, it's not going to significantly increase the power consumption by that much, since it's a really power efficient chip based on the newest 22nm architecture.
I own a Seasonic X-660 myself, on an i7-3770k @4.7Ghz, as well as a heavily overclocked GTX 680 Lightning without any problems, and just to get an idea of what the calculators have been thinking, I don't use up anywhere near 550w.
