I have been advised on a Graphics Card, but it is recommended I has a 400w psu. I have a 300w.

The one I have is the Lite-On PS-5301-08HF 300 Watt ATX Power Supply. The dimensions of the power supply are 150mm x 140mm x 85mm

What could you recommend these dimensions? best value for money the better...in other words, cheaper the better lol :)

Thank you!

cheaper the better

is not a good thing as far as PSUs are concerned a PSU failure can take out motherboard, cpu, memory as well as hard drives, i.e. itwi;; cost you a new PC and possibly all your data as well.

A Corsair 400W PSU may seem small, I would go for at least 500W, it will have no problem powering a PC that requires 200-300 watts of steady current:

If renewing a PSU check:

  1. The physical size of your PSU, some are hard to replace due to being a non standard size.

  2. The amount of power need from the PSU don't skimp.

  3. The correct connections for your equipment

1. Physical Dimensions

Besides the specs and form factors, the physical dimensions are also important factors in selecting a compatible power supply. Here is an outline of the physical dimensions of most standard power supplies:

ATX: 6x3.5x5.5", HxWxD. Most common. Uses 4 mounting screws.

Mini-ATX: 5x3.5x5", HxWxD. Rare size. Uses 4 mounting screws. Can be used in a regular ATX case, but often not the other way around.

MicroATX: 5x3x4", HxWxD. Use 3 mounting screws. Not interchangeable with ATX or miniATX.

Flex ATX: Even smaller than Micro ATX. Various sizes according to case specs; often not interchangeable.

Use the data above to determine if a particular power supply would fit your case.

The quality of a power supply can be estimated by its weight. While this is not a true scientific or thorough measurement of the power supply reliability, it is nevertheless a very simple and easy way for ordinary PC users to estimate and compare the quality of a power supply.

2. Power supply calculator http://www.antec.outervision.com/

3. Correct connections Some boards have 20 pin connectors others 24 pin There is often a 4 pin plug required to power Intel CPUs Molex D plugs for IDE HDD and CD/DVD drives SATA power connections for latest HDDs and DVD drives.

The physical size is ATX: 6x3.5x5.5", HxWxD. Most common. Uses 4 mounting screws.

Power supply needs...I will get a 500w, that will do it.

As for connections. the PSU I have now has

1 x 24-pin ATX Connector 1 x 4-pin P4 Connector 5 x Molex IDE Connector 1 x Floppy Connector 2 x SATA Connector

None of the Molex IDE connectors are being used. The Graphics Card I will get is EVGA GTX 550Ti SuperClocked 1GB GDDR5 DVI HDMI PCI-E. Not sure what PSU is best

You have a standard PSU so I'd say this £35 500W OCZ click here will do but it'll take your budget to over £120.

Alternatively you can have this £45 Zotac GT630 click here which doesn't need extra power supply & compatible with your existing 300W PSU.

It may not match the GTX550Ti's performance but at least a big improvement over the GT8500.

Hmmm. That Zotac GT630 might do the trick. It only has to last a year being able to play new games and I can get a new comp or better card then. Will get that one I think. Been 2 mopnths without playing a game and I can't take it no more lol. Thank you both :D
