Hello, I'm buying my Parts this week. I have a few questions... What is a Modular Power Supply? Do , I need it? I'm planning to run SLI GTX 560ti , Will 700 Watts be ok?

My System...
CPU: Intel Core i5-2500K 3.3GHz Quad-Core Processor (£164.98 @ Dabs)
CPU Cooler: Cooler Master RR-B10-212P-G1 76.8 CFM Sleeve Bearing CPU Cooler
Motherboard: MSI P67A-GD65 (B3) ATX LGA1155 Motherboard (£121.88 @ Buy.com UK) (This Board Good , Or should I go for the Z68 , Plus this Mobo has 2x PCIE 2.0 At X16 Mode instead of just one being at X16 mode and the other being at X8 mode.)
Memory: Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory (£56.98 @ Dabs)
Hard Drive: Samsung Spinpoint F3 1TB 3.5" 7200RPM Internal Hard Drive (£42.83 @ Scan.co.uk)
Video Card: Asus GeForce GTX 560 Ti 1GB Video Card (£179.98 @ Scan.co.uk)
Case: Cooler Master HAF 932 ATX Full Tower Case (£99.58 @ Scan.co.uk)
Power Supply: Corsair 650W ATX12V / EPS12V Power Supply (£64.99 @ Dabs)
Optical Drive: Sony DDU1681S-0B DVD/CD Drive (£11.98 @ Scan.co.uk)
Total: £743.20

Bump , can anyone help me out?

Each of those cards should draw a maximum of 170W (14,2A) so that power supply should be about right, even with overclocking on the CPU. You could get the 750W to be on the safe side, but that would likely increase power consumption at idle.
A moduler powersupply means the cables are not attached. Instead you get them seperate, and have to plug them in (its made so that its easy, don't worry) This helps making it easier to fit everything in the case as you only have the cables you need in there. It is definatly not needed in the HAF 932, but it can still be nice to keep things simple-looking.
Z68 is great if you need to encode video (P67 cannot access the GPU core in the 2500k to help with that) There is also some SSD caching, which allows you to use a small SSD as something inbetween RAM and a HDD.
If you don't need those things, get the 67P.

That looks like a really nice system, although I would be carefull about getting such a big case unles syou really need it.

For your motherboard id recommend going with a GEN3 board.

ASRock Extreme3 GEN3 is £115 at www.novatech.co.uk

It's SLI ready and has PCI 3.0 support with a z68 chipset.

The RAM you've listed looks really expensive at DABS. You can pick up the same stuff from www.SCAN.co.uk for £45 (sometimes as low as £40 if you check their "Today Only" deals).

500w PSU recommended for a single GTZ 560Ti, 750w recommended for SLI. Recommended PSU brands include: Corsair, Antec, SeaSonic, XFX.

i5-2500k can also be bought for £155 from SCAN ("Today Only" deals - its on there pretty much every single day though, usually as low as £153). http://www.scan.co.uk/todayonly/

I've looked at the ASRock board , it looks really nice and had better reviews than the MSI. But it only has PCIE 2.0 X16? I need to with it atleast X8 Mode or 16X mode.

It does run SLI at x8/x8

If your looking for SLI x16/x16 you need to be looking at boards like Gigabyte UD7, ASRock Extreme7 ($300+ boards).

650W is recommended for an i5 + 560Ti, and 750W for an additional 560Ti. PSUs will only draw from the wall what they need, so adding a bigger PSU won't necessarily increase power draw at idle (where is the power going to go?).

To tack onto this, a modular PSU is somewhat useless at lower wattages, since you'll only be running one or two GPUs. Non-modular power supplies in the 650W-850W range generally have 4x6+2 pin GPU plugs, enough for 2 GPUs. Modular PSUs become useful when you're only running one GPU with intent to upgrade on a PSU that can support 3-4.

I'd still suggest a Z68 board over P67. You get integrated video without an increase in price, and it's handy in the event of a GPU failure or even for motherboard debugging purposes.

As far as PCI-E slots go, the performance losses between x16/x16, x16/x8, and x8/x8 are very minimal. The only set up I'd be hesitant to run is x16/x4, which is the minimum requirement for Crossfire.

IMHO, Full towers are the way to go. I am never going back to a mid tower unless I absolutely can't afford it. There's tons of room, more convenient features, and better cooling. Plus, they look awesome :)

+1 to "almost" all of boilder1990's advice.

500w PSU is enough for single GTX 560Ti and i5-2500k

And full towers can be really unnecessary. There's plenty of space in a good mid-tower case for almost anything apart from an e-ATX motherboard and water-cooling. My CM Storm Scout has front, side, roof, rear fans, along with plenty of space for all components including SLI set ups.

Full tower cases can also run into issues with cable lengths. My XFX 750w XXX Edition would certainly have cable length issues in a full tower case, its only just long enough to fit in my Storm Scout.

Thanks for clearing this up. I'm going for the 750W PSU. I'm going to connect allot of Fans , and other PCIE X1 cards I use for editing and capturing HD Video , so I need the extra piece of Minds. Also , I'm planning to have A SSD and 2 More 2TB hard drives in the future , the Two HD's will be in RAID 0.

Hopefully , that will be Ok for 750 W.

A 500W PSU does supply the necessary amount of power, but a 650W has more headroom and reduces load on the PSU. That increases the lifespan of the PSU, and can make the difference in whether a "lower" quality PSU fails or not.

Not sure if I should go for a GTX 560ti or a XFX 2GB 6950. The 6950 has More FPS , From BF3 benchmarks but I'm not sure.

Anyone help me decide which one?

TBH it doesn't matter that much. What should be of concern is if BF3 turns out to be NVidia-favored, like Crysis is.

The beta currently isn't putting a huge load on the GPUs, so it's hard to tell what the game will require.
