Need a good power supply unit and fan (if any is needed) for the build below.
SLI OR CROSSFIRE: No
FAN+PSU BUDGET: ~$400
ADDITIONAL COMMENTS: I'd like it to be quiet and not eat up a hellacious amount of power. Don't want to have to add more than 2-3 fans. Not willing to mess with water cooling. Probably won't upgrade most parts for 4-5 years; my current computer lasted 8 years and I'd like another one that will last me for about as long. May upgrade CPU and graphics card a bit in a few years and/or add another HD.
450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)
The values apply to the whole system as opposed to just the graphics card so you should have ample power with a good 500-600W PSU. The recommended brands are Corsair, Antec, Seasonic etc. Stay away from anything cheap
As for fans, that case has 3 fans pre-installed which should provide decent airflow. There is room to add more if you wish though. Have a look over this guide for more info on basic case airflow:
If you have $400 to spend on the PSU and Fan, I would drop the 5770 and get a 5850, you'll then still have $250 to spend on the PSU and fan, which is still MORE than enough. You can get a good PSU for ~$100 (or less) Here is a solid one: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
As for the Fan, I assume you are meaning a CPU Cooler? if so, you can get a good one of those for $50 or less. Here is a good one of these as well: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
With those 2, you've got a total of $135 after MIR, which leaves you enough money to actually jump up to a 5870 which will last you MUCH longer than the 5770.
The build is a good one, but the graphics card seems underpowered compared to the rest of the system.
If your monitor is 1920 x 1080 or larger, a stronger card is appropriate.
If you are interested in quiet, I suggest you review cases, psu, fan and cooler articles on www.silentpcreview.com.
Even though the stock cooler will do the job, I suggest you look into a oem cooler with a 120mm slow turning fan. They are all good. It is much easier to install one initially while the motherboard is outside of the case as compared to removing the motherboard later.
I really don't plan to game too much, is the thing. Really the only thing I'll be using it for is (like I said) Diablo 3 and some PS1 and PS2 emulators. That's it. Don't plan to overclock or add a second video card. Not sure if video editing needs more than one video card or just a good CPU.
Anyway, I will definitely look into adding a second fan and may upgrade the graphics card but... I'm not sure at this point why I would need a better one, at least for my purposes...
Professional photo and video editing is cpu and memory intensive rather than gpu intensive. You've got that covered with the Intel Core i7 930 and the DDR3 1600 memory.
Playing games is gpu intensive. You've got that covered with the 5770 video card.
If you are positive that you will not be adding a second video card or overclocking, then I would recommend a high quality 500 to 550 watt power supply with more than sufficient current (amps) on the +12 volt rail and an energy efficiency certification. Such a psu can easily power a system equipped with any single video card made. You'll be covered if you decide to upgrade the video card. The Corsair VX550 is a heavy duty psu currently available at newegg.com for $79.99:
Corsair is a brand that has a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty.
I would not purchase additional case fans right away. The Coolermaster HAF 922 has very good ventilation, airflow, and cooling with the stock fans. You could always purchase additional fans later if necessary.
You didn't list a cpu heatsink and fan. For mainstream applications the stock cpu heatsink and fan that comes with the 930 are okay. However, for gaming sessions you might want to consider a third party cpu heatsink that will help lower temperatures. It doesn't have to be exotic or expensive. A Coolermaster Hyper 212+ which comes with a varaible speed fan would be good. The system can control the fan speed based on cpu temperature. It will help keep the noise level down.
Thanks for that - very helpful guys. In that case, it seems like I'm okay with what I have, based on what I'll be using it for. I'll go ahead and get that Corsair power supply (second recommendation it's had) and the CPU heatsink/fan (another second) and get ready to start building this thing.
