Which PSU?

Hi I've been juggling between the choices of a PSU and I was wonder if a 650W HX650 corsair PSU would work for my gear.

i7 930 (want to be able to OC maybe around 3.4 or 3.6ghz)
460GTX
DF-30 antec case with stock fans
CM V8 HSF
GB UD3R mobo if it matters

Btw I use Pccasegear.com 4 this. So if there IS a better PSU option over this which might be cheaper I'd love to hear about it to reduce costs as I'll probably keep this one build for a long while. :D

At 147 it beats out the XFX option by $2, so its a pretty good value considering the other offerings you have available on that site. Looking at the other 650W units it stocks i would say the 650HX is the best pick.

Ty you hunter, I reckon it should go well for one GPU.
as 4 my entire build is
CPUHS CoolerMaster V8 CPU Cooler $74.00
GPU EVGA GeForce GTX 460 768MB $239.00
DVD Sony AD7240SGB 22X SATA DVDRW Black OEM $29.00
TC Arctic Cooling MX-3 Thermal Compound (4g) $16.00
CPU Intel Core i7 930 $359.00
MOBO Gigabyte GA-X58A-UD3R Motherboard Rev2.0 $279.00
PSU Corsair HX-650 Power Supply $147.00
HDD Samsung SpinPoint F3 1TB HD103SJ $89.00
RAM G.Skill Ripjaws F3-12800CL8D-4GBRM (2x2GB) DDR3 $139.00
Case Antec Dark Fleet DF-30 Case $128.00

I will really want to OC the processor, as this will be my final build and ill be buying next week. I would really like if someone could suggest any improvements, cost, obvious flaws which shouldn't be experienced.

u want to stay with intel i7-930? or maybe try out an AMD processor? im not a certain resource so its ok if u ignore my suggestions.

do you want to have a small SSD for your os as well (with your 1tb)? or just ganna stick with the one drive?

u could get arctic silver 5 instead for the TC. a lot of people recomend it and its around 9.99 i think.

do you want to have water cooling? if its maintanence u dont want to deal with, you could always get a self maintaining one. jsut some things u could give a scond though.

I originally thought about AMD but I've always preferred Intel for some reasons. They expensive those SSDs? Because I've never done any research on them but I know their read speeds are amazing. Oh and the DF-30 has a quick slot for SSDs if I want to upgrade easily I guess (just looked at some, if i wanted to I'd upgrade after I get my initial computer). Arctic 5? May as well Idk much about the difference between the compounds tbh. All I know some are different to spread :p .

Has anyone ever OCed a i7 930 b4? if so how far did you get it with a HSF?

An i7 930 is the best you can get at a reasonable price, if you can do a build around an i7 930 in your budget there is no need to consider an AMD build, it wont be any better.

Most people report getting around 4GHz with a good heatsink like what you picked out, water cooling will add a significant amount onto the price and unless you get a high end loop a good air cooled setup will be as cool and OC just as well for about 200-300 less.

SSDs tend to add about $200 on, but they are significantly faster than HDDs and make good boot drives for your OS.

dont have much exp in oc-ing but some info on ssds. first off, they do have amazing read speeds. They also have NO MOVING PARTS which means it's quiet (no noise) faster boot times/loading times for example u can load a game on a hard drive in say... 2-3 minutes as to an ssd which can probably do it in around a minute or less.

another example is transferring stuff to another folder or something similar. what takes the average consumers hdd 10 minutes could take half the time or less jsut to say.

im pretty new to AMD as well but im getting a new build soon that has a AMD core. all my friends prefer the AMD processors cause of their stability appearently.

i think the 930 can be oc'd to around 4.0. im not certain cause i havent done this myself.

yes I will definitely consider a SSD 4 my OS in the foreseeable future. I saw this water cooling system for pretty damn cheap, Hydro Series H50 for $119. Although IDK how good it is :3 .

The Corsair H50 is good for compact systems that dont have enough space for a taller heatsink, but is beaten by most decent air coolers, the V8 is significantly better than the H50.
August 2, 2010 4:15:56 AM

Oh and I've also heard that the i7 750 can reach 4ghz as well. How much difference would there be between the 930 and the 750 OCed? I'll be looking at the 64gb to 128gb soon (when I have more money :p ). TBH The main reason I'm gonna build a computer is to upgrade from my 2 yr old Laptop which is kinda lagging behind. And I realise how funny gaming Laptops are.

hunter 315 is right though. the air cooling you chose would be better. im jsut not sure of the noise level.

The 930 has a few advantages, first the i5 750 doesnt have hyper threading so its only 4 physical cores and 4 logical cores, while the i7 930 is 4 physical cores and 8 logical cores which helps out on heavily multithreaded tasks like video encoding. It also packs triple channel memory, the higher bandwidth can be helpful for certain tasks, one review i saw of starcraft II showed that it did a bit better on the 930 than the 860 because it needed the better memory bandwidth. The i7 930 also has the X58 platform which gives you full 16x/16x SLI and Crossfire so you can throw in two high end GPUs and not worry about bottlenecking them at all.

Basically an i7 930 build is as high as you can go for a reasonable price, since the next faster processor goes for about $500 so its really not worth it.
August 2, 2010 4:31:55 AM

ahh k, Well If I do decide you upgrade my graphics scenario (like SLI or Xfirex) I'll have to get a better PSU probably 1k+ so I give myself OCing room. Co-incidentally you mentioned Starcraft 2 which is gonna be the main game I'm aiming to play :D , I figured the 460GTX would do that wonderfully. And because Starcraft 2 is kinda CPU intensive I didn't want to have it capped or anything by it. Plus given its OC possible it should last a few years. Before it become fossilized of course.

yeah I noticed that the 930 is good 4 the price, loled when I saw the crazy 6 core Intel CPUs for like 2 grand almost (1 of them which is more in AUS).

oh and btw SC2 doesn't use Multi-threading with their new game engine! The fools :(  oh well I gotta plenty of other games.

A 1k PSU is overkill, the GTX 460 doesnt use a ton of power and the HX650 is quite powerful for a 650W unit so it can handle 2 GTX 460s with some OCing fine.

The GTX 460 and SC2 are the hot trends for the week so i figured there was a pretty good chance that SC2 was going to be one of your main games.
