I bought a new system about 3 months ago now, it was custom built.

CPU: AMD Phenom II X2 560 Black Edition
Operating System: Microsoft® Windows 7 Home Premium 64-bit
Motherboard: Asus M4N68T-M
Memory: 4GB DDR3 1333mhz (2x 2GB)
Hard Drive: 500GB S-ATAII 3.0Gb/s
Optical Drive: 22x DVD±RW DL S-ATA
Graphics card: NVIDIA GeForce GTS 250 1GB
Case: Xigmatek Asgard

and finally my PSU is an ATX-500 500W.

When running my PC for a long time, most of the time gaming, the PSU starts to get very hot and what seems like the fan in it gets VERY noisy. When doing mundane tasks such as browsing the web etc. it is fine.

I have a feeling that it might be either it's not supplying enough power and is trying to hard or it has a very poor efficiency.

So I was wondering, is it the PSU that needs replacing/sorting out and if it is which one should I buy since I know compatibility is a big thing when it comes to these sorts of things.

Your feelings are correct. Many buidlers use low quality underpowered PSU's to increase profit at your expense.
550W is the bare minimum we suggest for any PCI-E GPU. For the GTS 250 I would want a 650W. SeaSonic-XFX-Corsair are all top quality.
What's your budget?

My budget is probably around £30 to £70 at maximum, I'd also want it to be quiet.

Looks like you're in the UK? Where do you shop online? Corsair are handled by many UK sites.

I've previously bought from Scan.co.uk and they seem to be the place to get your things from what I've heard although I'll go anywhere with a good deal.

I'm in the US so I am not familiar with any UK sites. Look for the b rands I mentioned on Post #2 or post a link to a site you want to use.

It's alright I have a general idea of what specs I need on it but I'm wondering, are there any compatibility issues with maybe the motherboard or other components? Should I only buy a certain type of pin or something of that nature?

This Scan.co.uk: Corsair Enthusiast TX V2 CMPSU-650TXV2UK 650W Power Supply (PSU) is a good PSU that comes with a 5 year warranty.

The PSU's brands I linked to will have all the proper connections to properly power your hardware.

Thanks Amd_Man.

This seems good but do I want a modular or non-modular PSU? Also is there anything a little cheaper, I know it would compromise quality.

This Scan.co.uk: Corsair TX CMPSU-650TXUK 650W Power Supply (PSU) is the origional version of that PSU and still carries a 5 year warranty. A Modular PSU of the same quality will cost more than both of these. The PSU is not something that should be used to cut costs as it provides the power to the rest of your (expensive) components.

EDIT: No problem Tyree.

I've found Scan.co.uk: XFX P1-650X-NLG9 XXX 650W Modular Power Supply (PSU) which is the same price as the others but it's modular. I'm assuming it's of a lesser quality then?

While it's alot better than the one your using now, I wouldn't use it. It only has a 2 year warranty so that says something.

I think that I'm going to with Scan.co.uk: Corsair Enthusiast TX V2 CMPSU-650TXV2UK 650W Power Supply (PSU) but one last question (sorry about all the questions I'm kinda new to this) the corsair has these connectors:

8 x 4pin Molex
2 x FDD Power
8 x SATA Power

and the XFX has:

1 x 4+4pin CPU +12V
6 x 4pin Molex
4 x 6+2pin PCI-E Power
1 x 8pin CPU +12V
2 x FDD Power
6 x SATA Power

I am alright with the corsairs?

Yes the Cosair will have all the required connectors that you'll need. The real difference is that the Cosair only has 2 PCi-e connectors while the XFI has 4. What that means is the corsair can power 2 graphics cards while the XFI has connectors for up to 4 cards. A 650w PSU wouldn't power 4 cards anyways so it's kinda pointless to have that many. I've had no problems with any of the Corairs TX line of PSU's.

Your welcome and please let us know how it goes. As a side note: your old PSU was getting so hot while you where gaming because it was struggling to provide the power reguired when your system was under load.

Another option for a non-modular from that site. Made by SeaSonic w/5 yr. warranty and cheaper.

Are you sure that's the correct link? It's made by Corsair the one you linked

Most PSU's are made by someone else. The PSU I linked to is sold by Corsair but made by SeaSonic and they don't get any better than SeaSonic.
