Apparently the PSU's that come with cases are just flimsey paperweights that are useless.
Im using a 160gb hardrive,a geforce 7600gt graphics card, amd x2 3800+ cpu and a msi motherboard.
I dont know what PSU i require, as i've been told that alot of PSU's that come pre-installed with cheap £20 cases are naff and if it cant cope i could potentially damage some expensive pc components.
I dont want to know how many watts i need or anything like that, i know ill will want at least 350w, refferably 400-450w. But i want a decent PSU that will be reliable and run all my components sufficiently.

thats what i've been told ill need although i wasnt planning to spend more on my case a psu than i am on my cpu!
So please dont answer unless you know abit about this, as i said before i dont want you just to do a search a find the cheapest 450w one for like £5 or something.

You'll need 15-30 watts for each hard drive, 15 watts per gig of Ram, 50-100 watts for the motherboard, about 100-125 for that particular graphics cars, 80-125 watts for the X2 cpu, 20--30 watts for any optical drives, 3 watts for each case fan, and about 10 watts for any pci card like sound or wirelss adaptors. To be safe take the upper limits of each. With your graphics card i would recommend a PSU with dual 12v rails, unless you want to pay for an expensive PSU like PC Power & Cooling. Use the Newegg website to look at reviews of all PSU's in the wattage you need but i would order from your country to save on shipping. I've never had a problem with Enermax, FSP Group, Antec, or Thermaltake. Like I mentioned earlier, PC Power& Cooling are the best but the are extremely expensive.

Yes, check Newegg- the user review are very useful. Also check PC Power & Cooling for better psus. Since you're using a 7600GT that doesn't require a dedicated PCI-E connecter, 400W should be fine.
If you plan on upgrading to a high-end video card like a Radeon X1950XT or GeForce 8800 series, then get a 500W with plenty on the 12V rail.

I am not going to name brands, because I dont know that many. If I were you, I would go with at least a 600W PSU. The only reason I say this is because you seem like you will be upgrading and if you add...say...another video card (SLI) or more case fans/lights, you will need more power. If you want to spend more money in the future, but be cheap now, just go with a 450W. That route will require you to most likely upgrade in the future. A little more £ now will make your system easier in the long run. Good luck!

Many cheap PSUs that come bundled with the case have low efficiency and weak +12V rail. Do get a 450 watter preferably complying with ATX V2.2 (hi-efficiency/dual +12V rails). A higher rated power supply runs cooler, lasts longer and gives you plenty of elbow room for upgrades.

Your PSU is something you don't want to skimp on. It's connected to everything in your computer.
I recently built a system : Intel Core 2 Duo 2.0 GHz. 3GB DDR2 RAM. 500GB HDD. 2 DVD RW's. 1 DVD ROM.
The case I bought came with a 450w. Not NEAR enough. I chunked out $160(USD btw) for a 650watt and it works perfectly.

Well, my PSU cost me £20 and it's still going strong, with 1.3GHz processor and 300GB HDD, with 3 fans in the case. And it came from PC world so it really is the bottom end.

get a psu with 4 or 5 eggs, and you'll be fine...
