Recommended PSU

I have a:
AMD Athlon X2 4800+
2Gb RAM (533Mhz)
Seagate 500GB HD
Seagate 150GB HD
ATI HD 2600XT
Hauppauge Nova T500 tv card
Wireless PCI card

Can anyone recommend a good psu for this system. I want a good one but at the same time i dont want to have to spend a fortune is possible.

Corsair 520HX should be more than enough for that system.
Its around USD 100 and easily one of the Best PSU's in tht range.

you could also consider a 600 watt OCZ gamexstream, here is link for newegg if you are in USA Newegg.com - OCZ GameXStream OCZ600GXSSLI ATX12V 600W Power Supply 100 - 240 V CB/CE/CSA/UL/FCC - Retail

Corsair 520HX... solid construction, quiet, more than enough modular cables included, built by highly regarded Seasonic.

eXtreme Power Supply Calculator Lite v2.5

there's a utility that i've used

Newegg.com - LOGISYS Computer PS550ABK ATX12V 550Watts Power Supply With SATA and 20/24 Pin connectors. 100 - 240 V - Retail

thats the PSU i have in my current system and it wont change when i upgrade to the C2D

currently i've got an FX55, 2.5GB Ram, 1Sata HD and 1 IDE hd, 8800GTS, X-Fi Gamer, 4LED fans, 1 CD/DVD R/RW DL and thats about it

Id recommend the Antec TruePower2.0, Very quite, has 1 120mm fan

IMHO, this PSU Calculator is more accurate than the extreme linked to above...

You list a TV card, so I'm assuming you are doing the Home Theatre thing, in which case noise could be a factor.

I have looked at about 8 PSUs recently, and the winner for me was the Antec Phantom 500. It is completely silent in normal operation, with a fan that only comes on when things get warm. It is a bit pricey, but has every possible connection, including SLI.

PSU's I don't like are:
Winsis - cheap,quiet but 2 quit within days.
Zen - totally silent fanless, but 1 major drawback - recovery time - after you turn off you have to wait until completely cold before you can turn on which can be 30mins to 6hours - huge variation between units.

good cheapos: Rosewill or Kingwin with 120mm fan

I'd suggest an ENERMAX Liberty 620W. This power supply is more then enough power plus the voltages on the 12V rails are sufficient if you decide to upgrade your vid card to something brand new. The only downfall is that its $150 but its well worth it.

I use the Corsair HX 620W ATX2.2 Modular SLI Complient PSU £77.99
Never had any probs, stable voltages on all power lines. Modular and comes ith extras.
