Hi guys, I'm currently looking for a PSU that is 150mm x 140mm x 85mm and has 400Ws and over and also has 3 4-pins connector for a Graphics Card - also it needs a 24-pin cable, my motherboard doesn't use a 20-pin power cable to power it.
I'm asking this cause I seriously don't have a clue for things like PSUs. Anyone got any good recommendations?
Additional information : Needs SATA Pin Connector and a 4-Pin ATX (to power the motherboard I think) I think these are included automatically right?
I am currently looking at this model. http://www.microdirect.co.uk/Home/Produc...n-12cm-fan-SATA

PSU are typically referred to by their form factor and not by the raw dimensions.
150mm x 140mm x 85mm is commonly referred to as an ATX form factor.
What you have linked to is a bargain basement power supply. Note where they say "various" when referring to the manufacturer.
It may run for awhile, but reliability is a concern. Spend some money and buy from a reliable manufacturer. sammorris is the resident expert on power supplies and has severl threads where he has recommended and (not) recommended several brands.

Thanks for your advice, I've just searched around the Forums, and saw that he recommends Corsair alot, I was just wondering, cause I saw that a Corsair 400W PSU could power 2 good graphics cards, is this true?
I basically need a 400-500W PSU that can power a GeForce 9600GT.
Thanks in Advance.

Flattered by the comments :P
I'll have to check the exact dimensions. If that's standard ATX sort of size there are plenty of options. If it's smaller than usual there are PSUs you can buy but not many.
You say it needs 3 4-pin connectors for graphics cards, but graphics card connectors are either 6 or 8 pins, 4-pin connectors are for the CPU (and are always included).
Aside from the model you've chosen being ghastly, you've also chosen a pretty terrible store, MicroDirect have a very poor customer service record.
What exact hardware do you need to run off this PSU? You may not need as much power as you think - many power supply requirements are greatly overstated. A Geforce 9600GT and, assuming a normal single CPU system will only need one 4 or 8-pin (CPU) and one 6-pin for the graphics card, not three. If you want two 9600GTs you still only need two 6-pins and either a 4-pin (most CPUs) or 8-pin (high end boards and core i7s) connector, which even some 450W units have. I will get back to you shortly with my recommendations.

The standard size for Corsair modular PSUs is 150x150x85mm - is this what you meant or is this too big? The non-modular versions are 150x140x85mm as they do not have the extra length of the modular connectors. All PSUs include the mandatory S-ATA power connectors, CPU and ATX 24-pin power connectors.
If you can stretch to 150mm length, your best bet is the 450W Corsair HX power supply - a model only available in Europe and not the US.
http://www.scan.co.uk/Products/450W-Cors...5-year-Warranty
This unit has been chosen as it has the required two 6-pin power connectors for two graphics cards.
If you do not need both 6-pins and will be using just one graphics card, then this is your unit:
http://www.ebuyer.com/product/150985
If you have to have the 140mm length but require two power connectors then you should choose this:
http://www.scan.co.uk/Products/550w-Cors...ranty-see-specs
Other than that, do you already have both 9600s? If not, I would strongly advise against buying another. For the same amount of money you can buy a card faster than both cards, which will allow you to sell the old 9600 and get some money back - this also means less energy used, less heat produced and it only requires a motherboard with a single PCI express 16x slot - wins all round. You could even potentially make use of the extra power the 450HX or 550VX offer by using a double power connector card like an HD4870 for more graphics performance.

No, I only have one 9600GT, I only asked that question for future reference.
I should be able to fix a 150 x 150 x 85 into my computer, it's just slightly longer, right?
I'm not sure what you mean by what kind of Hardware do I need to run off my PSU. Are you talking about my inside components like my CPU or things like Keyboard/Mouse.
I have a question, I {was} planning on getting the 400W Corsair PSU, but with this PSU, can I run off the latest Graphic Cards such at the GTX295/Radeon 4890? Also, do these cards require double 6-pin connectors like you said before?
Another question I have, if I buy the 550W Corsair but only need one Graphics Card at the moment (maybe sometime in the future I'd get a decent graphics card.) Would that be okay? Would there be any malfunctions if I don't use the second 6-pin connector?

Wishcross: 150mm long PSUs fit into practially any PC case, it's only an extra centimetre so as long as your existing PSU isn't hard up against something else it'll be fine.
By hardware I meant CPU, drives and graphics card. Peripherals like the mouse and keyboard hardly draw any power at all.
A 400W Corsair PSU is not OK to run new cards as it does not have the extra connector.
ddp: Assuming you mean not using both connectors for a 2-connector graphics card, you're out of touch, using both connectors on a graphics card is mandatory and has been for some time. However, it might be you mean not using the other connectors on a PSU, in which case that's of course fine and I apologise :P
I would advise against a Radeon HD4890/GTX275 as a new generation of graphics cards (DirectX11) is just arriving, one of which, the HD5870 is already out - you would be wise to keep your eye on those as they'll be much better value for money.
If you buy a 550W unit with both connectors (the 450HX will be fine too) you don't need to use them.
Using a graphics card that requires two connectors and only using one, your PC won't function at all, the screen will be blank and it will not boot windows.

Ahh I see.
My hardware is: 1 DVD Drive.
1 220GB Hard Drive
1 500GB External Hard Drive
Dual-Core Pentium 1.8GHZ + CPU Fan
3GB RAM
1 GeForce 9600GT.
I have another question, like you said, a PSU is important by Brand and not how much Watt it supplies.
You recommended me a 450W Corsair, would this be able to run that DirectX11 Graphics Card you talked about earlier?

Yes, it would run it fine. Be advised though, the fastest new cards are quite pricey (the HD5870 is currently $380 though it will drop), and very large, so check if they will fit your case before buying. The HD5850 is expected to be roughly $250 and much more manageable and is still triple the performance of a 9600GT.

Yet again, I have another question(lol).
The question is - would my Processor be able to run the DirectX11 Graphics Card? I'm scared that my Processor would not be good enough to run a very good Graphics Card in the near future.

Well it would work, but it would be a severe bottleneck, a DirectX11 graphics card wouldn't have to work very hard because the CPU wouldn't be fast enough to keep up.

What would you recommend as a good CPU processor then?
Would it be a Quad-Core?

Core 2 Quad, not Quad 2 core. Core 2 is the name of the technology, Quad signifies 4 cores. It doesn't say which Core 2 Quads though, given the age of the board it's probably just the Q6 series, which is now out of date and overpriced, unless you get a cheap one off ebay it's board upgrade time.

No waaay, damn, I've seriously got to buy a crap load of stuff even though I just bought this computer a year ago.
So, I really need something like 600 pounds just to get all this crap, haha epic.

Which is why you don't buy prebuilt PCs if you want to upgrade them.

True.
One more question, if I'm going to need to buy a case and a new motherboard, any recommendations?

What's the difference in the RAM slots?
Can't I just the ones currently in my computer?
Does that Motherboard has a Ethernet Port for a Router, I can't see one o_0.
EDIT: Also, any decent UK retail shops you can recommend? =P

No, as Core i5 uses DDR3 memory, not DDR2.
All motherboards have at least one ethernet port, this one included.
