looking for a power supply unit for a custom desktop

bobbothner · Apr 8, 2013

Hi, I want to build a custom desktop (for the fun of it, and to have a decent gaming platform, mostly games like the Witcher 2, Tomb raider, bioshock, etc). I have a 1920*1080 Dell monitor.

Here are the components I've selected so far:

motherboard: gigabyte ga-Z77X-D3H
CPU: intel i5 3350P
GPU: gigabyte HD 7850 OC 2GB
RAM: 8 GB corsair vengeance red
Hard Drive: 2TB Seagate
Case: In Win mana 136
optional: maybe an optical drive

I have read that choosing the right power supply is important, but don't really know what to look for. Could someone tell me what wattage etc I should look for?
Also, does the motherboard I chose support WIFI?

If you find anything wrong or that could be optimized in the components (or simply something I forgot...), let me know!! Thanks in advance!

this works great for the number of times ive used it while building a computer (6)

If you dont plan on doing any overclocking of your CPU, and only stick with the one GPU, I would say that you would be fine with a 550W

however, try to look for modular powersupplies, it helps with air flow and comes out alot cleaner.

It's incredibly important. Research this area heavily before you make the right decision. Hardware Secrets and Jonnyguru have the most comprehensive reviews on power supplies in all of the internet. If they say it's a good supply it's a good supply. If they say it's crap, it's crap. This index will also give you a good idea of what manufacturers use what OEMs: http://www.tomshardware.com/reviews/power-supply-oem-manufacturer,2913.html

Pretty much the most trusted names in PSUs are Antec, Seasonic, Corsair, XFX, and anything made by Super Flower (NZXT, PC Power & Cooling, Rosewill Capstone/Lightning), and Seasonic are among the best you can buy. This is one I usually recommend: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151096

Yeah pretty much all I ever use are generic USB adapters so get one of those.
