Do I have enough power for my build?

Hey all, was wondering if the power supply I have picked out is enough to power this stuff in addition to a couple 180 mm fans and a couple 120 mm fans. Will most likely be doing some overclocking, nothing too extreme though. Any other critiques or comments on the build are welcome as well.

and lastly the power supply in question, chosen for its single rail and 2x 6 pin pcie connectors, is 750w enough?

That is probably too much. I have a very similar system (only real difference is that I have a 4870 1gb vid card), and I run very nicely on a 650 watt PSU (Corsair). I'm also overclocking my E8500 to 3.8 Ghz.

You can probably use a name brand PSU rated at 550 watts and be fine.

Get a SATA burner.

The PSU is just fine. You'll only use it around 50% capacity, but that's where it's most efficient so it's not a bad thing. Also, $80 for that PSU is a steal. I paid $200 for mine last year.

Are you sure the GA-EP43-DS3L has all the features you will need? There are better boards with lots of extra features for $30 more, like the GA-EP45-UD3R or GA-EP45-UD3P.

$65 more buys you a faster version of that GTX 260 (216 processors instead of 192), with lower power consumption, from a more reliable manufacturer (XFX), and with a copy of Far Cry 2. I think it's worth it, if you're interested in Far Cry 2.

Thanks for the input and quick replies guys.

I was actually looking at the GA-EP45-UD3R as a possible upgrade for easier more reliable overclocking. Will probably go with it now.

Why the bigger HDD selection? Just for more storage space? If so, I can always pop in another 500 Gb when I need to. Space really isn't a big concern ATM.

I'll prolly stick with the 750W PC Power and Cooling PSU. $80 (after rebate) seems like too good a deal to pass up.

That bigger HDD is faster (higher density platters) and costs less per GB (8 GB/$ instead of 6.66 GB/$). It is a good idea IMO.

It's not space, it's speed. The WD6401AALS is much faster. The $$$ difference is peanuts.

Nice, I'll swap that out then.

Agreed here, good choice of PSU and good call on the HHD as well

I bought an eVGA GTX260-216 on sale from newegg in December for $220. There are some good deals out there.

I prefer to run my PSU's at 50% - 60% - better efficiency and they run cooler.

In the 500 - 800 GB HD size, the WD 640 is the one to get. Two 320 GB platters will be faster than two or three 250 GB platters.
