Need help making finishing touches ( psu selection !!!)

I would go with a 600w if you really want to play it safe. Out of all things the power supply is the last thing you want to cheap out on. And always make sure its at least 80 plus certified. Here is my recommendation: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

You're definitely right to question that PSU choice - most of what Raidmax makes is absolute crap, I've used their cases at work (who tends to purchase a lot of junk brands like Ultra, Apevia, Raidmax, Xclio, and Xion) and they've fallen apart easily. If their cases are bad, I wouldn't trust their PSUs.

With PSUs, you definitely get what you pay for, and the cheaper the PSU is, the worse it is in most cases. You want a good, solid, strong

This would be a better choice: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I think I'm gonna go with the first one as I'm on a tightbbudget ...is there anything in my build I can do bettEr on??
Also I'm not sure the difference with going 1600mhz ram or 1333mhz ram

Just realized that one is pretty bad too going through reviews ^so many people say it died on them >.< need to find good psu 50-70$ sufficient for my build :$

XFX Pro 550W Core Edition 80Plus Bronze $70 ($30 rebate)

I already recommended a good one for you that is in the 50-70 range http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Never look at the one egg reviews. It's all idiots that use it incorrectly or its doa so they rant and rave. It has 4 eggs and almost 150 reviews, it's a good psu. It sure as hell is better than the one you were going to get before.......

It is true that newegg reviews are usually not worth reading. But I wouldn't go for it either, especially not at $70.
The XFX Pro 550W Core Edition is a better buy, more 12V capacity (504W vs 528W), higher temperature rating (30C vs 50C).
If the CX600 V2 has the same choice of capacitors that the CX430 V2 has, then it has inferior capacitors to the XFX. (85C Samxon primary, 105C Teapo and Samxon secondaries vs 105C Chemi Con all round).
I suppose some of these differences could be considered academic, but the XFX is still the better unit.
