I was wondering what or if there were any significant performance differences between these two PSUs

They both seem to be top notch with only the ratings and wattage being the real differences. I've read everything I could find but a lot is hard to understand.

My main concern is ripple suppression and voltage regulation for dual GPU setups rather than saving on electric bills. I just would like to make sure I get a model that will not spike when under heavy load for 15 hours at a time.

Thanks!

The P2 has been running my setup for awhile now , no hiccups.

I have the P2 1000w, I can state that it's a fine PSU. I've never hooked up sensors to it to test it. That's going beyond what I'm willing to do. The Platinum units usually are slightly better on the issues of your concern, due to slightly higher quality internal components. I'm not thinking you'd ever notice the difference between the units though. My advice would be to make sure you have at least a 25% overbudget on power. If you need 800watts, then I wouldn't settle for less than 1000watts, especially if you plan to overclock. Heck, I go higher than 25% on all my systems, never know what sort of power spikes you get during hard usage. There's a PSU tier chart floating around that has both of these units in the top tier. Buy the one that fills your max peak power needs.
 


Nice, yeah I read that PSU Tier List here on Tom's and I found the PSUs on it as tier 1. My needs are 1000W and still includes a 200w overbudget, so the only thing I needed to know really was the quality between the two. Sounds like either one is good for CF/SLI.

My main concern was the spiking and feed of the power when under high stress. I game at least 3x per week as long as 15 hours in one sitting so a great PSU would probably one of the better things for me to drop an extra $30 on.

But would the 300w on the G2 be more useful than the slightly higher quality of the P2? Most people would never see the power savings but my computer is on around 20 hours per day since I fall asleep to movies and I'm an insomniac and I do game for ridiculous periods of time. A normal person might have no issues between them and I doubt I would either but my expectation is perfect on the PSU side since the PSU is basically the only part in a computer anyone can actually future proof (since the warranties are 7-10 years). It makes the extra $30 that much more incredible. Meanwhile a GPU can all but be guaranteed to require upgrading every 2 years if I were to splurge on something epic now, makign the extra money there a lot less valuable

I hope this makes sense! The case and PSU I'm expecting a looooooong time out of. The rest of the parts are going to be upgraded every 2 years most likely

I am salvaging my old SSDs, HDDs, peripherals and Windows 7 Ultimate SP1 (etc)
 
I have another option, if you're patient you can find this PSU for a similar price and I think it would be your ultimate solution.

I have this one in my main system. It replaced the P2 1000 watt. All I had to do was undo the modular cables and install the new one. I already had the sli cables in place. EVGA makes darn fine PSUs.
With those GPUs, I think you need every bit of juice you can get. Those Radeons are power thirsty.
 


nice, so it sounds like that are par for quality and the extra watts may be more applicable to my needs or future needs? I just wish there was a comprehensive review detailing the strengths and weaknesses for them both since they are neck in neck for price
