Building Computer

I bought new computer with the following specs.:
Motherboard: MSI P45 Platinum (MS-7512) (2 PCI, 2 PCI-E x1, 2 PCI-E x16, 4 DDR2 DIMM, Audio, Gigabit LAN, IEEE-1394).
CPU: Quad Core Intel Core 2 Quad Q9650, 3000 MHz (9 x 333).
RAM: OCZ DDR2 PC2-6400 8GB Platinum Quad Kit.
H.D: I have four hard disk from WDC Green 3*1 Tera SATA and one 500 GB SATA Green for the system.
GPU: MSI Radeon HD 4870X2, R4870X2-T2D2G-OC.
Display: View Sonic VX2255wm-2 [22" LCD] (QK9074330194).

The only thing left is the power supply and I need your Advice on one of these or any other you think it’s better:

Corsair HX1000W:

OCZ Z Series 1000W:

OCZ GameXStream 850W:

Toughpower Standard W0155RU 1000W:

I need your Advice on one of these or any other you think it’s better.
I will use this PC as Heavy Gamer and for Virtual software like VM Ware, Virtual Server and Virtual PC.
I have two devices using Bluetooth.

I have budget for the power supply around 400$.

  1. Go with Corsair
  2. +1 for Corsair. The company has an excellent reputation for high quality power supplies that are stable and reliable.

    I have a question for you. Why do you think you need a 1,000 watt power supply? According to your list of components your system has one HD Radeon 4870x2 graphics card. The video card does need that much power - about 260 watts and 22 amps at load. The rest of your system, even if it's overclocked doesn't need that much power either. Different technical reviews have slightly different power usage results but they are fairly close to each other.
  3. Corsair TX650 is all you need. Or if you want to go up a little - TX750. A 1 kw PSU is massive overkill.
  4. jsc is correct, you will never use a 1kw PSU with that system. I recommend looking into PC Power and Cooling, they are my preferred brand because their quality is some of the best on the market and they are all individually tested which makes the chances of a DOA PSU very low.
