When I bought my gaming rig last year, I tried to buy the power supply with a worst case scenario in mind, something that would last me for a long time; that a few years down the road, when it can no longer run new games well, I could always run 2 cards in sli, maybe overclock the gpu/cpu/ram.
Lately I've been thinking about also upgrading the fans in the future and possibly watercooling as well. I just checked out Thermaltake's power supply calculator, and, according to them, it looks like I should have gotten a much higher wattage psu (about 1500 watts). Is that a reliable online calculator? I've heard that 750 Watts will run 2x GTX580s in sli, but I do have a lot of other paraphernalia and want to overclock.
Rather than spend hours in front of a calculator to verify this, I was hoping you guys could give me some opinions based on experience.
My PSU is a Seasonic SS-850HT 850W ATX12V
Here's similar specs of what I want to upgrade to eventually:
Case: Fractal Design R3 (Mid Tower)
Fans: 10 fans:
x6 Scythe DFS123812-3000 "ULTRA KAZE" (or similar, im open to suggestion. 3 for the case, 3 for a radiator)
x4 Scythe Slip Stream Kaze Maru2 140 or Xigmatech XAF series (or similar, i'm open to suggestion)
Motherboard: ASRock Z68 Extreme4
CPU: i7 2600k (LGA 1155. 95 watt. probably try to overclock it to around 4.5 ghz at some point)
HDD: 2x Western Digital Caviar Black WD1002FAEX 1TB 7200 RPM SATA 6.0Gb/s (I'm leery of SSDs and their degradation over time)
Thanks for that info; I really do appreciate it. If I'm pushing it that hard, isn't it safe to say that it will crap out a lot faster than if I got something with more headroom, like a Seasonic 1000 watt psu?
