builiding a new gaming pc and iam confused on psu to get
heres what iam getting
intel core i5 3570k
2x 4gb ddr3 1333mhz
asrock z77 extreme 4
2x evga gtx 660 sc in sli
wd caviar black 1tb 64mb cache
ocz vertex 4 128 gb
case thermaltake chaser mk 1 (theres alot of fans here)
cpu cooling: does this even get in the equasion?
Notice: im planning to oc the 2 gtx cards even further to their maximum
cpu to 4.5ghz
I would skip the 2x 660 and get 1x of whatever that would get you and trade in some PSU wattage to get an even bigger video card budget.
The PCIE slots have usually been 75w, but the 6 pin PCIE connectors can do more than 75w I am pretty sure. Not that they should ideally do more, but I am pretty sure plenty of cards suck down a whole lot more than that off the PCIE connectors when OCd.
Anyway, I would go for a 670 or 680 and maybe an XFX 450w or Corsair CX430w.
The drawbacks for SLIng can be pretty horrible compared to the tiny potential upside.
If you are ever in doubt, a power meter can always be picked up at the local hardware store to tell you exactly(within the range of error for the unit it self) what the system uses. I am guessing you would be surprised how efficient today's systems are.
what country are you in? you can use the drop down box to select from several countries on pcpartpicker.com.
Use the power supply button and sort by price. I suggest selecting corsair and xfx from the boxes at the side
(antec often has 2 +12v rails you may need to balance and seasonic is overpriced, while corsair has decent
quality and some xfx power supplies are made by seasonic and a tremendous steal for the price right now).
The xfx 550w in particular seems fairly unbeatable as far as a combo of quality and number of amps on the
+12v rail for the price. It has 1 pcie 6+2pin and 1 6pin with 44A(528w) on the +12v rail. Even if you oc those
gtx660s, you won't exceed 150w each due to the limits of the peg slot and single 6pin connector. Your cpu
is 77w stock and probably wont go past 130w overclocked. That is the vast majority of system pull at any one
time right there(430w in a game, if that), so that xfx 550w should be more than plenty. It is jonnyguru.com
recommended(friend of hardwaresecrets who know how to properly test a gpu) and has a longer life ball
bearing fan with a 5 year warranty. 80+ bronze, too.
I might mention it is generally better to go with one more powerful gpu than 2 lesser ones. You don't have
to worry about whether a game has crossfire or sli support and you don't have to deal with potential micro-
stuttering(see gpu reviews at techreport in the last year or so for detailed reasons why). Have you considered
a couple hd7850s instead? They draw less power, overclock like beasts , and any perceived deficiency compared
to nvidia can either be worked around or is bull(save for physx, which means little in the grand scheme of all
games out now and due out soon). They are also less expensive than gtx660 by quite a bit.
well heres the prob
i will let my cousin get it for me xD and shes no computer expert and i live in PALESTINE in Gaza
everything here is 1.5 times pricier and theres everyone between the age of 18 and 40 cant get out due to security reasons(you have no idea what kind of hell im living thru)
my cousin is coming from egypt and its cheaper there
and another problem is im getting the other 660 after a year from now
the ssd after a few months
the case after 2 months
im just buying the basics cuz im on a tight budget
so the 670 and 660 ti is a no go
my budget is $650
Some replies were added while I was composing my last post. For less than 2 gtx660s, you could get a custom
hd7970(NOT ghz ed.), oc it yourself past gtx680/hd7970ghz ed. speeds, and enjoy gaming at 3x1920x1200 now
or for some time at a lower res. Here are links to that xfx 550w psu(ncix for price, newegg for specs, Canada too):
For people that can't afford the whole cost of a better card up front, we usually suggest ebaying the cheaper card to get back 90% of the cost when they save up whatever the second card would have costed.
I don't know how the secondary market is in Palestine, so YMMV.
thanks for eveyone who helped me out here
well i think i will go with the xfx 550w its only $70
or is that psu IF iam not OC the cpu and both gpu's?
Both the cpu and mobo will cost me $395
so i only got $255 to get a psu, ram and an hdd
and whetever is left from the $255 i will work to buy a 660...
Oh ***...hey guys do you think i should get the 550w psu and raise money to get a 670 instead of 2 660's one this year and the second 660 the next year?
But i dont think the 550w will b enough for 2 670's overclocked(if i will get a 670 i may get the evga gtx 670 cuz theres an agent here for evga)and an i5 3570k on 4.5 to 4.8 ghz
damn i have lots of questions
appreciate everyones help
If you are on a short budget, I wouldn't recommend doing a lot of OCing. If you blow your voltage regulators or something on the motherboard that is a whole lot of expense that you will have a hard time paying in order to get running again even at stock.
1x 670 and a 3570k will play pretty much anything just fine.
im planning on buying with the $650 without getting a video card
still one prob
im planning on getting a 670 ftw after a few months and another one when the 7 series is out
and im planning on oc them both and the cpu also
do you think i should get a 650w or 750w?
