Need some help please!

post #1 of 5
Thread Starter 
Hi all, I am new to the overclockers community, but I have been reading a lot on this site for a while now and has been a big help. I have a question for you.

I have recently got myself a nice (if not over sized) case from Lian Li and also an ASUS Sabretooth Z77 and Intel 520 solid state drive (I have just started building my PC if you have not yet guessed).

The question I wanted some help on is I plan to get an ivy bridge i7 3770k, an 800w PSU, 2x EVGA 680 4Gb FTW to run in SLI and a 1440 res screen (been used to the image quality on my iMac).

Just wanted to know if this will all work ok. I plan on corsair liquid cooling to OC my CPU as well.

Any info would be a great help as I do not want to buy it all and find there is going to be some problem.

Thanks!

you're looking okay. an 800 watt PSU is a bit much, a good quality 650-700 watt will be enough.

with the gtx 680 SLI using ~340 watts with 4 six pin power connections and allowing ~120 watts for your cpu, water pump, fans and whatnot on the 12 volt rail for ~39 amps
this is fine:
XFX 650W PRO650W Core Edition $74.99

just saying . . but like i said there won't be any problems with what you spec'd.

Thanks for the heads up. I think I may have posted this in the totally wrong place.......

What makes a good PSU apart from obviously the price that you pay?

Thanks

the first thing i look at is if it is certified 80+, bronze, silver, gold or platinum. the higher rated the efficiency the , hopefully, the better components it has. and any decent PSU will be able to supply at least 80% of it's rated power from the 12 volt. so a 700 watt PSU will 560 watts (700*.8) or 46.66 amps (560/12). the 12 volt rail supplies power to the cpu and graphics card which is the most power hungry components. the other "rails"; 3.3 and 5 volt do not need to supply that much power compared to the 12 volt rail.

here is a list of recommended PSUs:
