And yes it does make a difference. | ||

http://extreme.outervision.com/PSUEngine Use that calculator if you want. I did it for you already and the minimum PSU recommended is 581 Watts. 600 Watts is really holding back your system. Upgrade to 750 or 700. Just give yourself a little more room to breathe if you ever want to add more HDDs or w/e. | ||

I run Sc2 on Ultra settings at 50-60 fps with a Dual core CPU (albeit 4GHz) and a vastly inferior video card (Radeon 4890 - overclocked but still shouldn't keep up to a 580). Certainly there is something wrong. I would start with this list of things to check for: 1- Power Supply 2- Overheating 3- Drivers 4- Copious amounts of background applications 5- You don't mention how much RAM you have. I'm sure you have enough but if for some idiotic reason you only have 2 gigs or something, That could be a bottleneck. | ||

A 600W PSU can cost up to $200 FYI. I would gladly place my components in the care of an X650 instead of a shitty no name 1000W PSU. The fact that most of you think that a GTX 580 and a 1366 processor can use a combined load of more than 400W is delusional. If a power supply wasn't providing enough power to its components. The computer would be experiencing lockups, random reboots, or BSODs. Seriously. Go into your BIOS and try it. Lower the vcore to your CPU and see what happens... There is the chance that the PCI-E power connectors on the GTX 580 came loose or never connected and that could prove to be the problem. But for the last time, it is not the ****ing wattage of the power supply that is the problem. | ||

If you look at the grafic posted by eight.BiT on page 2 that is total system power consumption. Not just the 580. This is not the worst case scenario, so it is possible that his system draws more power, but that still won't get him to 600. The sound card also takes a bit, but not too much. What i am not sure about is this (useless) gaming network card that you have. It is in a PCI-E slot so if could draw power that might be significant in this scenario. Maybe i missed it but you didn't specify what exactly happens in the game when you have 30-60 fps. So do you start with no more than 60? Do you have vsync enabled maybe? Do you have reduce mouse lag enabled? Turn them both off and see if it makes a difference. So my first bet is that it is because of some wrong settings. If you are worried about the PSU try to remove this gaming network card and the sound card and remove any other devices besides mouse and keyboard. Then test if it makes a difference. | ||

Fairly certain that you would need 800+ just from basic head component math | ||

My ram is 4gb atm, I plan to upgrade to 8gb. I plan to do x2 gtx 580 SLI once I get more money, so what PSU would I need to support this? | ||

Forget about the 2 HDDs, multiple fans, sound card, network card and all the other things needed to run a computer. The GTX580 alone uses 389 watts when under a full load btw, so yes, a processor and gtx580 while playing SC2 easily eat up 400 watts of power. A PSU doesn't cost $200 either. I bought by Corsair 650W for $90 and even got $20 back in a MIR, so you are way off. a 750W PSU shouldn't cost him more than $140-$150. | ||

You probably don't have any or are referring to the anandtech bench which clearly states FULL SYSTEM load. Thanks for educating me that there are more components than the GPU and CPU because I clearly didn't know that... Clearly these other components consume a lot of power... gosh. A Seasonic x650 at one point did cost $200 and btw if you didn't know, the majority of Corsair PSUs are manufactured by Seasonic. | ||

600W is enough for this system, yes his power supply is not the best out there but if he had issues with his power supply, he'd be having more problems in the form of his computer actually fucking up - which I assume he isn't. There is nothing wrong with his computer full stop. That is the performance you should get, a GTX580 and a i7 isn't going to magically make Starcraft 2 run at 100fps on max settings, that's not how computer games work - in fact it should be running worse than a i5 760 because of the overhead you get from hyperthreading and that its turbo boost is older than the ones used on the Lynnfields. Its why you don't buy i7s for gaming because they provide zero (0) performance benefits full stop: enthusiasts buy LGA1366 because they want to make use of the PCI lanes or use the RAM for VMs. Crysis 2 is basically the only game that will benefit from it in the near future because it will accept up to 8 threads. | ||

Having 2 hard drives and a sound card in PCI with a network card pci-e will also be pulling more from the wall. Your hole system if you use the "antec power supply calculator" would be 870 watts but they always over do it a little. 750 watts should do the tricks. | ||

Minimum Recommended System Power (W): 600 The difference between a 600W and a 750W is ~50 U.S. dollars. Why did you choose to go for the minimum recommended system power? In my amateur opinion, that is a terrible idea unless you have worked the calculations.

A 600W PSU can only cost $200 if you have a working time machine (unless you're a sucker). | ||

Disable C1E ( stops execution ), EIST ( multiplier drop results in lower frequency at times ), and the on the motherboards for the i7, disable the thermal throttling one ( this one also slows down the cpu drastically ) ( that's also when the there's possible heat issues ) HT sometimes does slow down the computer and could be turned off, but it benefits encoding applications rather than gaming applications. | ||

The vast majority of the ones you listed have major flaws...in fact the only ones I'd trust without reading reviews (not Newegg reviews, proper reviews) are the PC Power and Cooling ones because of their long successful history. For instance the Coolermaster 750W GX Series has problems with fan noise, suppressing electrical noise and running within spec when drawing heavy loads and the Thermaltake TR2 RX 750W can't actually draw its specified loads when the operating temperature is hot and has problems suppressing noise and ripple during heavy loads. That shit can fry your computer if you're not careful. Its cute that people are just throwing around PSU wattages as if its the only thing that matters. | ||
