What PSU should I buy?

[spindle]

I reckon that I'm having power problems. My el-cheapo, came-with-the-case 400W PSU is trying to power 4 drives, 5 fans, the mobo etc.

The reason I think I am having problems, and I'm yet to prove this for sure, is that my USB modem suddenly loses power after about 10 mins or so. I've checked that Windows isn't set to power down the USB, and I've de-installed and re-installed the modem drivers. The modem was fine before I rebuilt, but with the rebuild I've added three case fans and one Coolermaster Aero CPU fan.

I disconnected one of the fans and a CD drive from the PSU last night and the modem stayed up. So chances are its the PSU.

Question is, what should I buy? It's just your average home PC with a few extra fans and (eventually) lights. Is 400W enough? I see that PSU's are rated for different amps etc. Not being much of an electrician I'm lost. Do I want a 500W PSU, or a 400W with bigger AMP rating, or one that glows green and blue and pink?

What's a good PSU for around the £50-60 mark (or less!)? Don't need anything flashy, I'd rather something solid and stable.

Tagan 480W PSU Easy! Around your price range and simply fantastic quality

Antec is the way to go. 430W for £64. Its the most reliable power supply I have used:

Another vote for the Tagan.

I'd also consider Enermax but there prob slightly out of your price range.

I personally would steer clear of Overclockers UK and go either scan or over-clock (my favourite were I got mine from)

Well, wherever I go get it from, the Tagan it shall be. Thanx !

Just wanted to add that it's definitely my PSU that needs replacing. I disconnected one of the fans and now my modem has been happily doing what it does best for about 4 hours now!

Tagan or CWT 550.

[PMM]

I know many a person that sware by the CWT 550

Bit pricier than the Tagan by the looks of it.

Edit: Stop press, scan.co.uk do it for less than £60. Still thinking I'll go with the Tagan though.

id vote for the CWT 550W, mate just got one and its very quiet and stable.

[spindle]

Oh oh too many choices brain overload!

So is it number of Watts I should be looking for or number of Amps or mixture of the two? What benefit would a 550W be over a 480W if you get my meaning?
