Earthwatt can usually be found on sale for ~ 20 - $30 if you look hard and would be far more than what you need

400w, i thought it needs more watts, like 650 or 750

No, that system would work on a quality 300w.

Just get the cheapest one you can find on that list, although you must decide if you need modular cables, because only rare low wattage psus have them.

what do you think ? do i need modular
for my quad core ?

Im trying to build here a gaming pc, a pc that can handle 1080p, made for HD

the case would be antex 902, so the PSU needs to handle , bunch of fans and neon

Modular just means you can choose which cables you plug into the PSU, so you don't have as much clutter in your case from the unused ones. It doesn't affect the performance itself. However, modular PSUs are typically more expensive, and, like Kasp1js said, not very common at lower wattage levels.

Uh, isn't an 8400 GS about roughly equivalent to the integrated HD Graphics 2000 already on the i5-2300? Also, why would you want either for a gaming computer?

What kind of graphics card are you really going to be using? That will determine the power supply wattage you need.

But unless you get a flagship model GPU, you'll have plenty of room left on a good 400W+ model.

ok , so in modular the cables go into the PSU.. thanks

so only based on my graphic card I choose which PSU to use ,thats what I needed to know
Mikeaj maybe you can help me with my configuration, i need opinions and recommendations on what and what not to use

No, not quite, but other components other than the CPU (an i5-2300 takes about 55W max if you're not using the integrated graphics) have relatively low power consumption. Hard drives are several watts each under normal usage, RAM sticks a little less, most case fans a couple watts each, and so on.

There is just a big difference between somebody using integrated graphics that use something on the order of 10W, compared to a high-end discrete graphics card that uses on the order of 250W. They take more than that when overclocked. Or you could use multiple high-end discrete graphics cards.

This is why the graphics card(s) are the dominant factors in power consumption, followed by the CPU. See the stickied power supply calculator thread.

I was saying that since we already know the CPU, other components other than the GPU are not going to make much difference.

You could run the system off of a 120W PicoPSU or may want to get a decent 450W or so power supply, depending on which graphics card you pick.
