I'm going to build a new PC, my first one actually, and I have already chosen all the parts I want and the power supply is the only thing left.
Here are the parts I picked:


Case: NZXT Phantom

Processor: Intel Core i5-2500K Sandy Bridge 3.3GHz

Motherboard: MSI Z68MA-ED55 (B3) LGA 1155 Intel Z68 HDMI

RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)

Graphics Card: AMD Radeon HD 6970

Hard Drive: SAMSUNG Spinpoint F3 HD103SJ 1TB

DVD Burner: SAMSUNG SH-222AB - OEM

So could someone please recommend me a good psu??
Also, if I'm getting all 7 fans for the NZXT Phantom case and I won't overclock the 2500k, do I really need a cpu cooling system??
Thank you for your time :)

A good 550W, or 600W should do just fine. Look for: Antec, PC P&C, Corsair, Enermax, and Silverstone. I recommend an aftermarket cooler myself, but since you are not OC'ing it isn't needed.

A Radeon HD 6970 has a maximum board power of 250 Watts. This means that the graphics card itself may draw up to 20.8 Amps from the +12 Volt rails.

For a single Radeon HD 6970 graphics card system AMD recommends a 550 Watt or greater power supply with a +12 Volt current rating of 42 Amps or greater and with at least one 150W 8-pin PCI Express supplementary power connector and one 75W 6-pin PCI Express supplementary power connector.

For a two Radeon HD 6970 graphics card 2-way CrossFireX system AMD recommends a 800 Watt or greater power supply with a +12 Volt current rating of 62 Amps or greater and with at least two 150W 8-pin PCI Express supplementary power connectors and two 75W 6-pin PCI Express supplementary power connectors.

Since you're not overclocking the Intel Core i5-2500K the Intel supplied CPU cooler should work just fine.

What is your power supply budget?

Do you want a modular power supply?

Does the power supply's efficiency matter to you?

My budget for the psu is around $140, I don't really need a modular power supply, and obviusly the more efficient the better =P

Do you ever plan on running two Radeon HD 6970 graphics cards in 2-way CrossFireX mode?

Just stepping into the thread :D  I may be running two HD 6970's in the future, do you have any recommendations for a PSU in that case? I have a similar budget ($140 wouldn't be too much, but I'd like to save money if possible).
