Buying a PSU.

Steel_Nugget · Feb 12, 2014

Here is the one I'm looking at http://www.newegg.com/Product/Product.aspx?Item=N82E16817151108&clickid=wJq1M6wGry261wSUoU0E1za8UkTUUV1pW3FGz40&iradid=97618&ircid=2106&irpid=79301&nm_mc=AFC-IR&cm_mmc=AFC-IR-_-na-_-na-_-na
and here is the computer it will be powering http://pcpartpicker.com/p/2QUYe
Would you trust the power supply? Meaning do you trust the brand in reliability? Also if it caught fire and fried my mb while the warranty is still there would they replace the mb because there product was faulty?
Thanks!

Yes. but 850w is alot you can get away with 650....

seasonic is a good brand so dont worry.

HEXiT · Feb 12, 2014

its seasonic so yes its very decent even at 80+ bronze...
you could drop down to a 750w unit and get 80+silver for about the same price. but the power saving wont make much difference to your quarterly bill.

NiCoM · Feb 12, 2014

Seasonic is a very good company, i have a 550w Seasonic psu powering a even more power hungry system than yours.
by the way 850w is overkill, you should seek a 650w instead, would still leave some headroom.

If the psu fries your pc, they're only going to replace the psu. But the better the brand & quality, the more "safety equipment" does the psu have against any failures.

all you need is a 550w psu. Look at seasonic G 550w and rosewill Capstone 550m. If you will be overclocking really hard. (Overvolting).

Here is a Highend Psu
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171080 85$ after rebate

HEXiT · Feb 12, 2014

gotta give it to the mods... they know there apples...
although i have seen a lot of complaints towards the corsair gs and rm psu's (this may just be down to numbers sold rather than a high fail rate).

Dark Lord of Tech · Feb 12, 2014

I personally don't care for the RM series.

Steel_Nugget · Feb 12, 2014

Sorry forgot to add, the reason the Wattage is so high is because I plan on SLIing the card in under a year.

The reason its 850w is because I plan on SLIing in under a year. Thanks for the response!

HEXiT · Feb 12, 2014

then yeah its a good choice.

qbsinfo · Feb 12, 2014

Steel_Nugget :

this will freak you out:

i know people that SLI 770s with a 750 watt PSU and not have problems.

and yes, they are overclocking too.

Dark Lord of Tech · Feb 12, 2014

+ 1 ^

Thanks. That will save me some money. Do you know the recommended amount of watts for 770 SLI?

GeForce GTX 770 SLI review - Power Consumption

GeForce GTX 770 2x SLI - On your average system the cards require you to have a 700~800 Watt power supply unit as minimum.

BUT every system is different; on average an intel setup will use less power than an AMD (not just the cpu but also the chipset on the motherboard) and overclocking will use more. (again the intel will use less power.) lets take a look at a similar system of what you have in mind that is OC'd:

now that is an 8350 (uses a little more than your's as you can see for the stock speeds) but lets use it to error on the side of caution.) the power is measure w/o taking into account the PSU efficiency. lets assume its 90% so we have 264.87 then add the power usage that guru 3d got: 402 (which might be a slightly heavy handed since techpower up gets between 180- 192 for "peak power" for a single card [192*2= 384] but again that would be an error on the side of caution.)

that's a reasonably over estimated 665 watts. and keep in mind not all of that is on the 12 volt rail; mostly just the cpu and gpu - a few watts for fans and HD motor. BUT a quality 750 watt PSU can handle that load for gaming w/o any problems.

got it?
