Which power supply and ram?

[M-Section9]

This would be my first pc build and I am a having trouble choosing these two parts. I have 2 psu's in mind Corsair 650tx or 750tx. Don't know if 650 would be enough. As far as the ram goes i'm going for 4g(2x2gb). Anyone know some ram thatis compatible with this board. All advice is greatly appreciated.

What I currently have is:

Monitor - LG 20" LED monitor E2050
Hard Drive - WD 500gb Caviar Black 7200 rpm
Case - Cooler Master Gladiator 600
Processor - Core i5 750
DVD Burner - Lite-on 24x
Video Card - Geforce GT240
Motherboard - Asus p7p55d-e lx
3 Cooler master 120mm led fans 2000rpm(case came with 2)

500 watts would be more than enough for those specs, with that in mind, the Corsair TX550.
People say OCZ ram is junk but I've had no problems with it on several P55 and X58 builds, and it's on the QVL.

Based on what you have listed now a Corsair 400CX would be plenty.

G.Skill Ripjaws 4GB DDR3 1600 Cas7 would be a great match for your CPU and MB.

A little more power is never harmful.. With those regards, i'd also suggest the Corsair VX 550 as suggested by DellUser1.. WR2's suggestion takes care of your RAM worries definitely.. Those GSkill's are very good..

A minimum of a 300 Watt power supply with +12V current rating of 18 Amps is recommended.
Therefore, I would go for one of these PSUs:

CORSAIR CX400 400W (by Seasonic)
CORSAIR VX450 450W (by Seasonic)
ENERMAX Pro82+ (EPR425AWT II) 425W
SEASONIC S12II 430W
SEASONIC S12II Bronze 430W
OCZ StealthXStream 400W (by CWT)

Concerning the memory, I would go for this one:
