8800GTS SLI - what PSU?

This is my first thread ever in a non swedish forum, but anyway.
I hope that you guys could help me out with telling me how powerfull my PSU must be to run this system:

Intel Core 2 QUAD Q9450 2.66GHz 12MB
Asus Extreme GeForce 8800GTS 512MB
Asus Extreme GeForce 8800GTS 512MB= SLI
Auzen X-Fi Prelude 7.1 Dolby Digital Live
OCZ Platinum XTC 2x2048MB
Samsung HD753LJ 750GB 7200rpm 32MB SATA2
6 of : Noctua NF-S12-1200 Sound-optimised + a ThermalRight ultra-120 extreme

I thought of using a 620W quality PSU: http://www.newegg.com/product/produc...82E16817139002

Do you guys 620W will be enough for this system, light clocking included?
thx for good answers!

  1. With two 8800GTS in SLI, I would recommend at least PCP&P Silencer 750W:
  2. You could get away with a 600w power supply only if you bought the PC P&C silencer 610w, but if you are paying that much then you might as well spend about $20 more for the 750w, and feel safe.
  3. Yes, I have one, it's a very good choice. See here: http://www.xtremesystems.org/forums/showthread.php?t=108088
  4. 9800gx2

  5. The 620HX can handle even two 8800GTX cards, let alone two 8800 GTS. Still. I agree with the others about the Silencer 750W. It would give you more room for future upgrades.
  6. The Corsair TX750W is 60$ here in Sweden so I think that maybe that is another good choice.
    Or is the Pc P&C a better PSU?
    TX750W- quality + noiselevel?
  7. TX750W = nonexpensive
    PC P&C Silencer 750W = Quality

    Thats about it.
  8. PC P&C is usually regarded as the best pick for quality. Here in the US, prices are similar between the PC P&C and Corsair power supplies, making the former the better choice. However if the situation is different in Sweden and the TX750W is significantly cheaper, it isn't a bad choice at all.
  9. I've changed my mind.
    Yea prices here are a lot worse. iPhone etc i can buy from the US, but a PC. naah that's a bit 2 far.

    Since my comp. will cost me a looot more than 60$ and it will be my babe for the next years, why should I save 60 bucks instead of raw quality.

    I'll go with the PC P&C!
    How is that PSU if we talk; quality, performace and noiselevel?
