As for the power supplies I'm looking at (Yes I plan to crowd source this whole PC.)

As for the video card I'm  looking at the Nvidia 570 card with a i7 or i5.

What dose everyone think?

if I remember correctly the 560 has a faster clock speeds than the 570  and it's cheaper slightly maybe worth down grade slightly and save up for the dual core graphics cards in a couple of years

When it comes to power supplies, I'm always for more is better. 1000w is probably way more than enough. But one never knows what you may add to the system down the road. :)

I'm running an i7-2600k o/c'd @ 4.9ghz with an aftermarket cooler, and a pair of GTX 570's and it's awesome.

As I said before...the lazer series is better then the mach 1.  I have a mach 1 and love it...it now powers my 2 gpu's, and my other PSU powers the rest.

I personally like Antec, Thermaltake, Coolmaster and Kingwin PSUs, since they are all very well built.   (not just some wires and capacitors enclosed with aluminum foil) They are not the cheapest kids on the block but they are work horses and and will last a long time!  I am also a huge fan of the modular PSU design to cut down on extra cables and increase airflow in my cases.

My pet peeve PSU Company is Ultra Brand PSUs!!! (On my 4th return for my 500W, and had to fight tooth and nail to do each return!)

Back to PSUs....make sure you get one that packs the most punch on the +12V Rail!  More 12V rails is not as good as more AMPs on fewer rails.  Some PSUs have 6 rails but only 20-35A per rail.  Others have 2 rails with 40-80A each and some only have 1 rail with 104A, so please keep this in mind.

Hope this feedback helps!
CHEERS!!

OK I understand people have brands they like to use. But what about the specs on the two listed above witch are better and why?

I've been running this 24/7 for nearly a year with my amd quadcore and MSI R5830.

nVidia GTX570 requires a minimum of 550W and 38A on the PSU's +12V rail(s)!

Both the PSUs you have posted above have enough WATTS, but they do not have enough juice (AMPS) on the +12V rail to optimally power the 570 card you want to put in!! The Kingwin ABT-1 only has 20-35A, and the Kingwin Lazer has 20-33A on the +12V rails.

Will both of those PSUs work with the 570?   well yeah....but you will be stressing the power supply at max graphics settings which will eventually kill the PSU.

What would you recommend getting?

This is what i use http://www.corsair.com/power-supplies/professional-series-1/hx850w.html And what i will recommend.


Sabo.

Are there any cheaper options under $150?

GOA.Luke*BK*

Try this one, Cooler Master GX.  $70 after rebate.  750 watt with a 60a single rail.  I have never used this one but I do have a Cooler Master (module model) and have not had any problems.
