Power Supply

[AlbertKropp]

I have the 4th gen intel i7 3.4 ghz nvidia geforce gtx 645 1tb hardrive 460w power supply.

I am going to get the Nvidia geforce gtx 660 SC and i read that it requires a minimum power of 450w i have a power supply with 460w so when they say 450w do they mean the graphics card itself requires 450w or it needs a system with a 450w or greater power supply.

Plaese tell me what you think.

Now i think i'll go for the gtx 760 SC
And the corsair 750w PSU

[AlbertKropp]

what card would you recoment that's better but not over 250$ ?

if all you are concerned about is just getting better play for the 2 or 3 games you play now, the 660 will do fine. But if you were to spend the money on a new psu, then I would recommend something like this gtx760 for $250 as the minimum. But then you have to add in the cost of a new decent psu, so there is another $75.

but that is just my opinion.

well, that is "about" $75. I was just guessing on the amount since I didn't actually look for one to price. A corsair 750W is a good psu, if it will fit in your dell. If you get that psu, I would definately go for the gtx760 at the very least.

[AlbertKropp]

yeah it can fit in there i messured and good ghess:)

it'l take me awhile to save that much$$$ but i'll do it

Hi,
the total power requirement of a system as such, is the sum of ALL consumer.
This includes the Motherboard, CPU and any other additional devices e.g. usb hub and you mentioned somewhere a CD ROM that also will consume even when in idle.
So, if your Video card manufacturer specifies a minimum of 450W, you are running on the edge or beyond already.
Your I7 is probably around 120W full load 450+120=570W just two consumer.
The terrible byte HDD is taking probably another 25W, technically you are already beyond...
Furthermore, if you push a 600W supply constantly to the edge, temperature will increase which causes in return a lower efficiency until it sweats so hard and quits.
The 750W mentioned earlier is probably a good choice to run your system efficiently and not at the last breath.

[AlbertKropp]

yeah

What... The... Hell?

Your math and explanation is supremely messed up and are giving FALSE advice..

a GTX 660 draws a maximum draw of 140watts, possibly a little more if its overclocked
a GTX 770 has a max draw of 170watts, again a little more if overclocked.

a 450w recommended Powersupply is for TOTAL PC POSSIBLE Consumption and is being on the safe/logical side. The Recommendation DOES NOT mean that the Graphics Card will use 450watts of power at full load.

a 500w PSU is the lowest recommended PSU with enough headroom for most systems. When it comes to Mid-High range PCs 650w-750w in my opinion is best when any kind of overclocking will be done.

And for the record, a Hard Drive does not take 25watts. 5-10watts IF that depending on the Hard Drive, around 2-5watts or so if its an SSD.

Atleast know what you are talking about before you give advice.

thanks for helping i thought my pc was going to burn out if i did'nt get a better power supply.

When it comes to PSU's brand can make a difference as much as actual wattage does.

With low Quality PSUs actual wattage may be lower than what is stated.

Anyway, if you have the money a 750w Fully Modular PSU wont hurt. Corsair, XFX, EVGA, and Ultra are all good PSU brands.

[AlbertKropp]

yeah the one i'm looking at is corsair

Better throw in $20 more and get HX 750. Ten times better quality.

Only difference is that it's 0.79" longer. Not a problem since space behind the PSU is empty inside majority of cases unless you have some extra-mini case.
