Thank you sosofm, I figured I would open a new thread after completing all the components for the build. I appreciate your feedback especially regarding the GPU from the other thread. I am actually a bit torn between the Asus 7950 you mentioned and the XFX. I may most likely purchase the video card last in hopes of AMD sorting out driver issues so I can get a better understanding from those who currently own 7xxx series.
Go look at Jonny Guru for a review on that unit (it is one of the best resources for current PSU information). The LZP-1000 is arguably the best 1000w PSU on the market at the moment (Seasonic being the alternative). I would recommend Super Flower (the OEM of this Kingwin PSU) over Seasonic OEM PSUs due to the Seasonic units still having issues with coil whine. Performance wise, they trade blows depending on the test.
The Kingwin unit is also $50 cheaper and it has a longer warranty.
I was actually going to use the PSU in my 2 year old system, Cooler Master Silent Pro Gold Series 800W but I fell into the trap of combo deals and purchased the 1050W because of the discounted deal price.
Looking back now, I should have spent a bit more time researching PSUs before purchase. Definitely rushed that one. The Kingwin unit is very very tempting. I think I may have to make a last minute change on the PSU Thank you for the info regarding the Kingwin.
Customer reviews are great for seeing if a PSU frequently comes DOA or has other out-of-the-box issues. It isn't, however, a good indicator of performance since enthusiast PC parts have a long history of people jumping on bandwagons. All the units you posted are Seasonic OEM with various ages in terms of the platform they are based off of. The only unit that would even makes sense to compare to the Kingwin LZP-1000 is the XFX P1-1000-BELX, but why spend 60 dollars more? Not to mention the recent track record of coil whine in newer Seasonic designs. I sent back a Corsair AX series PSU 4 times to try to get one without coil whine for a customer's high end build. Corsair was happy to accommodate me, but who wants to deal with RMAs for a month and a half?
When you buy something you need luck too. Everybody recommend Asus mobos but a lot of them are DOA or need RMA because they have something. Gigabyte the same thing. Even the bigest brands do mistakes.
It is simple math. When you buy the really high end $200+ mobos, failures are more prominent merely because there is a fraction of those units being made compared to mobos between $75-$125. The last top of the line motherboard I purchase was my MSI K8N Neo2 Platinum. Full featured motherboards can be had for less than $100, 97% of the time, that will work just fine for a custom build.
He doesn't need 1000W of power.. For 2 7970s, at most he will need 850W. 1000W would be needed for 2 580 fermis.
No, he does not need 1000W of power. A nice 650-750 watt PSU could handle this no problem. However, it is kind of nice knowing that you don't have to worry about purchasing another PSU for a long long time.
Another Super Flower OEM PSU that is rock solid. I've started using Rosewill CAPSTONE for all my recent builds. Also, stepping down to a smaller 750 watt unit and keeping 80Plus Platinum is a bit pointless due to how close pricing is to the 1000 watt units. If you want to step down in wattage, go for an 80Plus Gold. Otherwise, for 80Plus Platinum 1000 watts is sort of a sweet spot for pricing.
I certainly contemplated a 850w PSU but my reasoning whether flawed or not is peace of mind as (iknowhowtofixit) mentioned. Thank you for all the help thus far everybody.
One last bit of hesitation I seek advice on, I know I mentioned the H100 in my build but after a week of researching I am unsure of the route to go; air cooled or the H100?
I am actually digging the Phanteks PH-TC14PE but these coolers at this price point are huge with possible motherboard layout complications. Any experience and/or advice regarding the x79 Sabertooth specifically would be a plus. Thank you.
