finally got the computer assembled. it was really nice to build (last one I built was 10+ years ago!). getting pretty good temps and nice airflow. thanks to all for the help
Holy Slappin' Batman! It's STICKIED!!!
Wasn't looking...
Expect less replies to the thread now that it has become part of everyone's peripheral vision.
Welp so much for those, either their auto price correction system kicked in or someone typed in the wrong numbers, price is up to $53 AND they're out of stock.
Also worth nothing the MSI Twin Frozr 7950 is now $330 + $8 shipping.
New update, mostly just price changes. Not super happy with $70 for the PSU, let me know if you spot any good deals and I will update the build.
I'm looking to build a new PC and this guide looks like a good jumping off point for me. I have a quick question though, how do you determine how big a PSU you need? It seems like only the graphics card lists how much power it uses.
Did you not include the promo? It's another 15% from the original pre-rebate price so it's actually $56.50 AP AR (unless you're taxed like I am)
Basic math really, you add up the values of the maximum possible power draw of the components you want (mainly CPU + GPU) and then set yourself a slight overhead for overclocking, capacitor aging, etc. Hard drives and such do add to the power draw but are usually only a few watts on their own anyways. For accurate values of how much wattage you need from a PSU you need to really look at the power draws in proper tests like the one AT performs. The "suggested" minimum on video cards is typically highly overestimated just to make sure people have enough power.
Ok. The GPU here says 500W min and the CPU is 77W so that puts us at 577W (which you say might be an overestimate because the GPU might not need 500W). 600W is enough clearance for that?
Awesome, thanks for the help! One more question, do you think it's worth waiting until next week to order a graphics card (b/c of AMD's price cuts)?
