750watt vs 850watt for GTX 560 ti SLI
i bought a dell xps 630i three years ago, and i have upgraded it a lot since but im still using their stock PSU.(750 Watt MAX model DT50E).
so im not really sure if their psu can handle the new parts.
here is what im using now:
GTX 560 ti (SLI in the future)
i5 2500k 3.3ghz stock cooler (going to get the H80 soon, and Over clocking)
Asrock p67 extreme 4
Gskill ripjaw (2 x 4GB) 1333mhz
ST3500418AS ATA 500gig HHD 7200
ive been looking at the Corsair AX 750w or 850w. right now everything seems to be ok. just dont want it to die and take anything else with it. which do you think would be the best?
Also side question. does anyone know what lighting guides were used in the vesta g1? i have 2 logisys cold cathodes,but they are too bright and the ones in the vesta g1 look a lot better.
750w is fine, in the unrealistic event other than stress testing that you reach maximum draw you'll still be well within specs and efficiency with the 750 model. Even the 650w model would hold up but run a little warm and outside of it's efficiency zone. You could grab the 850w and possibly save a few pennies per year in power savings.
as for the green lighting in the vesta g1 I believe they used green LED coolermaster r4 fans. NCIX.com - Buy Coolermaster R4-L2R-20 120MM Green LED Case Fan 2000RPM 69CFM 19DBA 3/4 Pin - COOLERMASTER - R4-L2R-20AG/CG - in Canada
thanx for the response
i know they also used two 12 inch green cathodes (top and bottom) but didnt say what they were exactly. like i said i have two green cathode but they are much brighter and im looking for something with a light glow like the g1.
750 is enough, but with an 850w your system will be more stable if you pull off extreme oc's on your cards and cpu, or if you upgrade to more power hungry cards
Headroom is always good, get the best PSU you can afford, it's always a money well spent in my books.
I wouldn't recommend that CoolerMaster though, look for a Corsair AX / Antec HCP / Seasonic X at the 750W - 850W range.
I am not sure about the included model of PSU, but 750w is fine for a SLI 560Ti setup. How many watts/amps can the 12v rail handle?
ok so i just turned on my computer and one of my two 120mm sickleflow fans didnt start right up it would shake and the LED lights would come on for a second then stop i had to spin the fan with my finger to get it to go.
also when im playing skyrim i noticed that my LED lights dim and brighten this is the first time ive seen them do that. i have the Corsair 560d and i have the fans plugged into the fan controller. i know that some LED fan light dim as they are undervolted.
is that what it is or should i get to ordering that new PSU?
That dimming doesn't looks good to me... about the fans themselves there's no problem with that, but if they get undervolted under load then your hardware is as well.
Yeah sounds like your PSU is having large voltage drops under load. My guess is its not up to the task. Can you take a picture of the psu with wattage ratings?
well just ordered my new corsair AX 850w it was on sale and with mail in rebate i got it for less than the
AX 750w :). glad i did now my computer seems to be revving up randomly.
its a very good chance that the psu is dying, could it be that it just cant handle my my pc with all the upgrades that i put in it, but if i put it back in its old case with all the old parts that it would be ok. was going to give my sister my old pc once i got a new psu.
