Well if you want mostly show and some go, that would be it. Yes it should work for just about any build, but the X2's have a shaky past, so you can decide. Like JEDIYoda says, do a google search and see for yourself. You can then make a more informed decision. For $100 I'd go with the Corsair hx520w PSU. It has a
5 yr. warranty and runs cooler and probably quieter than that X2. It has
40A on the 12V rails at
50C!!!!! Look below:
Corsair HX Series Features:
Supports the latest ATX12V v2.2 and EPS12V 2.91 standards and is backwards compatible with ATX12V 2.01 systems.
Guaranteed compatibility with dual-GPU configurations.
Double forward switching circuitry design offers high efficiency,
up to 80% under wide load range.
Active Power Factor Correction with PF value=0.99 provides clean and reliable power to your system.
Universal AC input 90~264V automatically scans and detects the correct voltage. No more hassle of flipping that tiny red switch!
Ultra quiet 120mm double ball-bearing fan delivers excellent airflow at an exceptionally low noise level by varying the RPM in response to temperature.
Guaranteed to deliver rated specifications at
50ºC.
Triple 12V Rails provide independent reliable power to the CPU, video card and other components with a combined rating of 50A (
40A on 520W) maximum! Advanced circuitry design that automatically enables power sharing between the triple +12V rails in an event of overload on any single +12V rail.
Powerful +5Vsb rail with
3A rating.
Over Current/Voltage/Power Protection, Under Voltage Protection, and Short Circuit Protection provide maximum safety for your critical system components.
105ºC rated industrial grade capacitors provide uncompromised performance and reliability, delivering 4 times the lifespan of conventional 85ºC rated capacitors.
Enhanced modular flexible cables enable easier cable routing and increased airflow in the system.
Gold Plated connectors provide oxide free ultra low-resistance contact between the power supply and your critical components.
8 Serial ATA connectors (4 on 520W).

110VAC and
25°C Ambient Condition
FCC and UL Recognized
50A on the 12V rails is nice, but it's at only
25C as noted above.
You can decide, but that is the direction that I'd go.
