Building a gaming system

Hi everyone

I'm looking to put together a gaming rig and build it myself.

I think I've done a good job finding components that will compliment each other, but I'm getting bogged down trying to work out what kind of PSU and Case to buy.

Here's my ideal rig so far, yet to order parts:

Component Model
Processor Intel Core i7-2600k 3.40GHz (Sandybridge) Socket LGA1155 Processor - Retail
Motherboard Asus P8P67 PRO P67 Socket 1155 USB 3.0 Bluetooth 8 Channel Audio ATX Motherboard
Graphics Card OcUK Value GeForce GTX 480 1536MB GDDR5 PCI-Express Graphics Card
Memory Corsair Vengeance 12GB (3x4GB) DDR3 1600Mhz Memory Kit CL9 1.5v Non-ECC Unbuffered
CPU Cooler Arctic Cooling Freezer 7 Pro Rev 2 CPU Cooler

I'm intending to start with just one GTX 480 card but I WILL be buying a second and setting up a SLI system in the reasonably near future.

What I need advice in, please, is what kind of watt power supply and subsequent case/cooling systems to invest in.

I've currently pencilled in these components:

Power Supply Corsair TX 950W ATX SLI Compliant Power Supply
Case Antec 1200 Twelve Hundred Ultimate Gaming Case - Black

Based on a topic I read on here regarding power supplies for a i7 system.

Would anyone mind running the rule over my proposed rig and helping me out, maybe some suggestions on different components etc.

My top level price for the system now (minus the SLI) is going to be £1,100 to £1,250.

Many thanks

First off, no point in getting 3 sticks of RAM. Sandy Bridge is dual channel, so you'll want to go with 2 or 4. 2 (8GB total) will be fine.

The 850W Corsair TX will be fine for that system, even with SLI. See here: http://www.extreme.outervision.com/PSUEngine . I got 781W min, 831W recommended with conservative component estimates and 20% capacitor aging, which you likely won't ever get to.

That case has good reviews and plenty of space to make building easy. If you want to reduce noise you could replace the tri-cool fans that come with it, but it's not necessary.

Those 480s are expensive.. I don't have time right now to check benchmarks, but would dual 570s or even HD 6950s give better performance for less money?

Hi, thanks for the help.

I've taken on board your suggestions and settled on a final build. Once again would anyone mind checking the build and letting me know if the PSU would be sufficient.

Processor === Intel Core i7-2600k 3.40GHz (Sandybridge) Socket LGA1155 Processor - Retail
Motherboard === Asus P8P67 PRO P67 Socket 1155 USB 3.0 Bluetooth 8 Channel Audio ATX Motherboard
Graphics Card === Gigabyte GTX 570 1280MB GDDR5 Dual DVI Mini HDMI PCI-E Graphics Card
Memory === G Skill Ripjaws 8GB (2x4GB) DDR3 1333mhz Cas9 Dual Channel Memory
CPU Cooler === Arctic Cooling Freezer 7 Pro Rev 2 CPU Cooler
Power Supply === Corsair 950W TX Series PSU - 78A 12V Rail
Case === Coolermaster HAF 932 Full Tower Case - High Air Flow Design - No PSU

SSD Drive === Kingston 64GB SSDNow V100 2.5" SATAII Read=250MB/sec, Write=145MB/sec
SATA Drive === Samsung HD103SJ Spinpoint F3 1TB Hard Drive SATAII 7200rpm 32MB Cache
Optical Drive === LiteOn iHBS112 12x BD-RE with DVD±RW DL & RAM SATA Blu-Ray Drive - OEM Black

Any final advice would be greatly appreciated.

I've managed to put this together for just over £1,300 which is slightly above budget but well worth it in my opinion.

Thanks in advance!

Oh and I am still intending to SLI with another GTX 570 at some point in the future and could look to add a sound card at some point.

Yep, that PSU will be more than sufficient. The 850TX would be fine too.

If you want to save some cash, the 2500K is significantly better bang for the buck than the 2600K.

You'd also save a few bucks with this RAM (which is the same speed as the G.Skills) - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I like the HDD and have no opinion on the SDD. :)
