Suitable replacement for Tagan 480W PSU

[FatalSaviour]

I've just had to use my own personal TG480U01 PSU to repair a work PC.
I'll be looking to replace this with something similar, so I'm currently looking into suitable models.

High efficiency (fairly standard I guess these days) and low noise are fairly high on my priority list, and modular cables are nice.

So I'm currently thinking of something like the Corsair HX 520W PSU.

I'll be using it to power an MSI P55-GD80 MB, i7 870 CPU, currently a 7900GTO, although that may change to a 4890 soon, and at least 4 HDs etc etc?
I'm a little bit unsure whether 4 SATA power cables will cut it - I'm aware that the 620W version has 8 connections, but it's a fair bit more expensive - is it possible to order extra connectors from Corsair?

Would this be my best bet, or should I be considering some others as well?

For instance, I've heard good things about BeQuiet PSUs, but I'm a bit wary of some of these newer brands (Hiper went bust a little while ago did they not?). OCZ have never really been on my list of considerations, but again, should they be?

Thanks for all your help guys, sorry for the rambling post!

BeQuiet is a German brand that is very popular in Europe and has only recently released PSUs into the UK (amid critical applause and fanfare from the IT press ) I can vouch for the quality of their PSUs as I own one which I think I am slightly in love with... (slightly)

The 550W version that I have easily has enough cables for 4+ HDDs but BeQuiet PSUs are generally quite expensive but imho the PSU is so silent and well built (to a shining dark polish) that I'd be happy to pay the premium again. That's all I have to say about BeQuiet PSUs

Corsair will send you extra modular cables for the HX series of power supplies http://forums.hexus.net/cases-psus/1...ar-cables.html . Enermax are another good brand worth considering. JonnyGuru http://www.jonnyguru.com/index.php and HardwareSecrets http://www.hardwaresecrets.com/page/power do v.good PSU reviews. Be Quiet are a very good brand but unfortunately to above sites are lacking any reviews of them. Some of the higher end Antec models are very good too but some of the cheaper models aren't so good.

Thanks for all of the links watercooled.
I currently have 3 Antec PSUs in use (2x NeoHE 430 and 1x NeoHE 550W), and they have proven to be really great PSUs - they're quiet, and Antec's customer service has been amazing.

I would buy another Antec without hesitation. The only reason why I haven't is that initially with the NeoHEs there were some teething problems where some MBs wouldn't work with the PSUs. I realise that the chance of this happening again is rare, but it would be quite nice to have a PSU from another manufacturer handy, just in case I have to test a rig for problems such as these (silly as that might sound?).
I haven't written Antec off completely yet as I say, as all my experiences with them have been positive. I try not to remain too blind to any one brand though at the same time...we shall see!
