I'm trying to figure out if a power supply will work with a system i am building. I have used a few of the calculators and the general amount is a 750w

I have never needed one this big before so i thought i would ask people who knew

This is the power supply im thinking of using [CORSAIR CMPSU-750TX 750W] - http://www.newegg.com/Product/Product.aspx?Item=N82E168...



CPU
- Intel Core i7-2600 Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W

Motherboard
- ASUS P8P67 PRO LGA 1155 Intel P67

Graphics Card
- GIGABYTE GV-N465MT-1GI GeForce GTX 465 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16

Memory
- G.SKILL Ripjaws Series 4GB 240-Pin DDR3 1333

Optical Drive
- LG Black Blu-ray Disc Combo SATA Model UH10LS20 LightScribe Support

Case
- Rosewill BLACKHAWK Gaming ATX Mid Tower Computer Case (Comes with 5 fans (3 blue 120mm) + (120mm) + (1blue 140mm)

HD
- Western Digital Caviar Black WD5002AALX 500GB 7200 RPM SATA 6.0Gb/s


I am planning on getting 4 sticks of the ram and eventually 2 of the drives.

I just really want to be sure that the system will work and wont need a power suppy upgrade in the future. And that it will also be able to power thumb drives and a new cpu fan later on.

Thanks a lot guys your the best!

That power supply will last you quite a while, it can power most dual card setups.

A few changes i would make to that build, get a GTX 460 or 560 instead of the GTX 465, its actually slower and hotter than the GTX 460 1GB ironically.

Also, swap the HDD for the Samsung F3 1TB, you should be able to find it at about the same price for twice the space and a little extra speed.

Would i be pushing my luck too hard if i wanted to drop down to a 650w supply?

Also good call on the 465, i didn't know that.

You could run that system on a good 550W unit if you dont plan to SLI in the future, so a 650W certainly wont be pushing your luck. I would look into the Seasonic S12II 520W unit or the XFX 650W unit as alternatives.

A 750w would cover you for a 2nd card, this is slso a good option along with the Corsair you listed.

If you have no intention of adding another card save some money

Im actually going to go with the next step up corsair its a 650w for 5$ more. Really don't have an intention of getting a second card and ive actually have changed a few components now but they shouldnt require any additional power.

Oh that is nice, only 30 watts lower but $20 cheaper means i can save a little cash. Silly question, but the corsair says its compatible with the i7 the seasonic does not. Im sure its fine but i thought i would mention it.

Easy, you could probably run 2x460's with that psu but it only has 2xpci-e cables.
