PSU Recommendation

My old PSU is a box of crap that I need replaced. I love finding a good deal and unfortunately that has caused me to buy several PSU in the past two years, so this time I'm willing to splurge a little on the side of caution. First of all, look at my specs:

ASUS Crosshair IV Formula 890FX
AMD Phenom II X4 965 BE 3.4GHz
SAPPHIRE 100312-3SR Radeon HD 6950 2GB
G.SKILL Sniper Series 8GB 1866 (PC3 14900) 9-10-9-28 1.5V

I will only be running one HD and one SSD in the near future so I'm not too worried about their power consumption here. I have no idea how much power this rig is actually using, but I guessed around 550-600W and pulled a few suggestions from Newegg:

Antec NEO ECO 520W - $40 after promo

OCZ ModXStream Pro 600W - $65 after promo

SeaSonic S12II 620 Bronze - $82

Please post your which one would be best for my system or another recommendation if you have one.

Of the 3 the Seasonic is the best. Other OEMs to consider are Corsair & PC Power & Cooling (which is OCZ owned).

all three will do the job (and are well reviewed) plus the two davcon linked

the antec 520w is a very good PSU using a seasonic platform and has just as much 12v power as the modstream 600, plus its $35 after the MIR (you won't find a better PSU for the price)

the modstream has modular cables although I tend to use just as many cables in non-modular PSU as I do modular so I find that aspect not as important to me.

the seasonic is an excellent PSU

the antec EW linked by davcon is an excellent budget unit

I assumed the Seasonic was the best to begin with, but for the value I don't know if it's worth twice the price of a PSU that might work very well in my computer.

The XFX PSU looks like a great value, but since I hardly believe I need more than 600W, the extra 150W would just be eating up my electricity bill wouldn't it? Do either of you have a guess at my required wattage?

The Antec 520 honestly looks like the best deal in my opinion. If that model really uses a Seasonic platform that almost makes the decision for me. However, 520W might not be enough for my computer. If I OC my CPU to 4.0GHz with 1.4-1.45V where would my wattage be at?

you are correct (500w+ PSU with 35a+ on the 12v) as you won't break 325w during gaming. the 750w will let you CF down the road if that interests you
Test System Specs
- Intel Core i7 920 (Overclocked @ 3.70GHz)
- x3 2GB G.Skill DDR3 PC3-12800 (CAS 9-9-9-24)
- Asus P6T Deluxe (Intel X58)

The XFX is made by Seasonic btw and a higher wattage psu does not use more power.
Your pc only draws the power it requires from the wall.
80+ ratings determine how efficient a psu does this and that's related directly to your electric bill.
Both units i listed are 80+ Bronze certified so they are efficient.

Now the XFX 750W is looking to be the best deal here. Newegg has it posted for $130 with decent ratings. I read the XFX Core edition PSUs weren't the best series on the market, is this just hearsay? I'm using this thread as a reference: http://www.eggxpert.com/forums/thread/323050.aspx

Thanks for the link to the Antec information, very useful.

Don't go by user reviews on Newegg while some are very helpful and informative,most aren't.

+1 and the xfx PSU are very good units (seasonic platform again) but I would say; I have read about customer support & rebate issues. I have also seen them pass off lesser video cards as gimped or different models.

ati 4860, nvidia 9600XT, selling gimped ATI 5570

Read a couple more reviews for the XFX PRO750W and I will making the purchase later today. The PSU looks like it has a TON of wires I won't be using considering how bare my PC is, I hope it comes with a velcro wrap tie or something. Modular would have been a plus here, but I don't feel like paying for that feature.

Thanks to Davcon and Dirtyferret for all your help and guidance. :)

I'd go for the antec instead, $50 is an incredible value for that PSU
