Corsair HX650W is a quality modular PSU. 650w is definitely enough for your build.

Where are you located? Newegg had a combo deal with $153 after mail-in rebate with Corsair HX650w + 16GB Corsair Vengeance LP RAM.

The combo is now $180 after mail-in rebate:

If you can sell 8GB for ~$40, you've got a nice deal there. Or, wait to see what pops up around Black Friday/Cyber Monday.

thx for the suggestions!
i guess i missed a GREAT DEAL RIGHT THERE
the reason why i didnt go for 16GB ram is cuz i dont need that much for gaming
thats why i just ordered the 8gb today

whats a good price on HX650?

For a system running a single Radeon HD 6870 graphics card a power supply with a minimum combined +12 Volt continuous current rating of 26 Amps or greater and with at least two 6-pin PCI Express supplementary power connectors is recommended.

Even a 450 Watt power supply unit, like the Corsair CMPSU-450HX semi modular PSU with its +12 Volt continuous current rating of 33 Amps and with two 6+2-pin PCI-Express supplementary power connectors, will work.

It's not the wattage of the power supply that determines whether or not it is sufficient to properly power the system. The most important PSU specification is its combined +12 Volt continuous current rating. If the PSU isn't able to meet this base specification requirement then it's not going to work properly with your system no matter how high the PSU's labelled wattage is.

If you can get a Corsair Professional Series HX650W (CMPSU-650HX) for $100 then definitely buy it since they are usually priced above $115.

The Corsair Professional Series HX650W (CMPSU-650HX) will have enough reserve capacity to allow you to run your system with two Radeon HD 6870 graphics cards in 2-way CrossFireX mode if you choose to do so in the future.

$100 is a good price for the HX650.
Better psu imo for what it costs compared to the HX.

Only some OCZ models are good.

The OCZ 750W Fatal1ty Series (OCZ750FTY) should work fine for your system configuration. Here's a review of that unit by a reputable power supply review site:

Yep the OZC Fatal1ty is a good unit!
Personally i'd fork over @$20 extra for the Seasonic M12D based XFX.

im kinda stuck among XFX 750W PRO750W XXX Edition, corsair HX 650W, OCZ fatal1ty 650W

all are modular, price not vary by a lot....which performs the best out of them?
which can last me longer?

The Corsair Professional HX650W (CMPSU-650HX) is too expensive for what you get compared to the other two.

The OCZ 750W Fatal1ty Series (OCZ750FTY) +12 Volt continuous current rating is 8 Amps less than that of the XFX.

The XFX ProSeries 750W XXX Edition Semi-Modular (P1-750B-NLG9) is the best out of the three you've listed. It has the best electrical performance and the best efficiency.

The XFX is superior to the others in performance and efficiency.
They are all semi-modular and good units.
Like i said earlier the XFX is the best deal for what you're getting.
My ranking in order of quality.
1.XFX - Seasonic oem
2.Corsair - Seasonic
3.OZC-Topower

so overall rating, would be xfx > corsair > ocz as for as power supplies quality and performance/?

I don't place any trust in EggXpert.

The rating of xfx > corsair > ocz is only for the three specific models that you were considering.

The ranking will change based on the models you choose to compare.
