Corsair 750w

that is an excellent power supply, one of the best. But what are the specs of the computer you are going to use it in?
 
Cant go wrong with it, great unit for a good price. Spend a few bucks more though and you can get the king of all 750W non modular power supplies:

Or a semi-modular unit: (The zalman power supplies are excellent, quiet, and provide very stable clean power with low ripple)

Basically any of these or the corsair will run any system out there except the highest end tri/quad sli/crossfire setups.
 
get the Corsair.

I have one, runs everything in my Sig perfectly

I can maybe add another GTX295 (thats probably pushing it...)

brilliant PSU. Good stats (efficiency and all that jazz), good electronics, guarantee, very quiet,

I think corsair makes the best PSU's.

the PCP&C is also great (on par with the corsair), the only thing i dont like is that the fan is only a 80mm at the back.

The Corsair Discplaces more air, (meaning better cooling), and is cheaper...

The fan size means nothing, these units do not produce enough heat(due to their effeciency) for it to matter much, and the pcp&c makes far superior units to corsair. Corsair uses CWT internals, cant complain decent middle/higher end internals, however pcp&c uses seasonic internals which generally speaking is the best that you can get. Heck, the best ATX power supply in the world only uses an 80mm fan(the pcp&c turbocool 1200W with a rated 100A +12v rail, but each comes with a spec sheet telling its maximum continuous and peak loads)

6. SHOULD AN ATX POWER SUPPLY BE COOLED WITH A 120MM FAN?


Most low-noise ATX power supplies today utilize a top-mounted 120mm fan rather than a rear-mounted 80mm fan. The 120's favorable reputation is based on the fact that under low to medium load conditions, the 120mm fan provides sufficient cooling at low RPM and low RPM fans are generally very quiet.

However, problems occur with this design when the load exceeds 50%-60%. Because the 120mm fan consumes about 1.5" of vertical space inside the PSU, heat sinks, capacitors, and other components are about 30% smaller in height compared to a PSU with a rear-mounted fan. The smaller parts can handle less current, so the maximum power available with the 120mm design is limited. And, because the heat sinks have less surface area, more air flow is needed with this design to keep the thermal situation under control. With 80%-100% load, the 120's fan speed can double and the noise level can jump by up to 20dB.

In conclusion, for systems that require more than 50% of the power supply's capacity, a well-engineered PSU with a rear-mounted 80mm fan will provide superior performance and reliability (due to larger components) at a noise level comparable to a PSU equipped with a 120mm fan.

if you like corsair you might want to look at the HX series instead of the TX series you selected. The HX series is of higher quality and more efficient, just a little more expensive tho. but it might be worth it.
 
I'm running it in a:

AMD-Gigabyte motherboard: GA-MA770T-UD3P

AMD-AM3 CPU: x4 955 Deneb black editon.

Patriot- Ram: 2x2gb Patriot gammer series 1600

XFX-Graphics Card: Radeon 4890

Operating System: Windows 7

Thats all it for now. I'm not going to crossfire, since board only has one slot anyways.

Heck, you can go cheaper with a corsair 650W, OCZ Fatal1ty 700W, 610W Silencer, or a modular 750W or so zalman unit(the 600W modular zalman is only $2 less than the 750W) easily with that setup.

Quite honestly, Take your pick, any of these will run your setup, you have a range between ones that will run your current setup just fine, the higher end ones that will run a future setup with crossfire or such if you want, or ones that will handle pretty much any singlecard as well a few cheaper couple dual card setups(eg- 610W silencer). A cheaper unit such as the modxstream 600W will easily power your current setup or a singlecard, but hard to run a dual card on it. Or something like the 750W corsair, silencer, zalman, or antec will run most dual card setups.

And the main reason you can use a 80mm fan on the back is linear air flow, with a bottom mount fan it has to blow up over the components and then somehow find its way out the back, while an 80mm rear fan will blow linearly over the components then out the rear).

I just replaced a 4 rail Silverstone 700 with a Corsair 850HX. Seems I didn't balance the load sufficiently between the 4 rails, and when the overloaded rail shut down it took down my RAID drive long enough for total drive failure. I'm now a believer in the single rail design and also recommend going a little larger than you might think you need, as a quality power supply should last for a number of builds, (or major upgrades).
