I'm about to finish buying all the parts for my first computer build, but before I do I want to make sure I'll have enough power.

Here's my setup:

AMD Phenom II x4 955 BE CPU

Asus Crosshair III Formula Motherboard

Antec 902 Case

Xigmatek Dark Knight CPU HSF

XFX Radeon HD 4770 Video Card

G.Skill 4GB DDR3 1600 RAM

Sony Optiarc Black CD/DVD Burner

Western Digital Caviar Blue 640GB 7200RPM Hard Drive




Now all I need is they power supply.
I was looking at this Corsair 750w Power Supply:

But I'm not sure if it's going to be enough to power my machine.
If anyone could help me with this problem, it would be appreciated.

Thanks,
Daniel

That PSU is plenty for that rig.

actually for that rig, you could get away with a Corsair 550w (450w if you only use the 4770)

only get the Corsair 750w if you plan to get dual gpu's at some point

The Corsair TX750 is overkill for the ATI Radeon HD 4770 video card. That card is an energy efficient card. It is not a power hog. The Corsair VX450 is plenty if you are going to use only one 4770. The Corsair VX550 is plenty for a system with two 4770 cards in Crossfire mode. Those are the official ATI recommendations:

I would switch your hard drive out to the Samsung Spinpoint F3 500GB hard drive. It is a faster hard drive. If you want a WD, I would go with the 640GB Black over the 640GB Blue.

Use Caviar Black instead of the Blue.

The weakest point for this build is the graphics card, unless this rig is just for casual gaming. Anyway, you could do crossfire with another 4770 anytime.

I have another question guys, I was looking at RAM on Newegg and under the features section it sometimes says "4GB memory kit (2 x 2GB) for use with Dual Channel DDR3 Intel Core i5 and Core i7 processors Intel XMP". Does that mean it only works with Intel CPU's and not with AMD, or it's made to be used with Intel and can be used with AMD?

It will work on AMD.

It states Core i5 and Core i7 because they have specific voltage requirements of 1.65V or less for their memory. Anything higher on those chipsets will damage the CPU.

In that case, anyone know any good DDR3 RAM for around $100?

Doesn't seem to have any reviews. Is it reliable?

The Corsair RAM is okay but with the Cas7 timings the G.SKILL I've listed will actually be better. Cas7 DDR3 1333 will perform better than Cas9 DDR3 1600.

During the past two weeks I've read every technical review I could find. The DDR3 1300 memory is definitely the sweet spot, especially if you are gamer. It would be different if you were going to use it with high end mainstream applications such as those used by professional photograpers and film editors.
