XFX ATI Radeon 4770 w/ this 450w PSU?

Hi all,

Given that the 4770 requires a *minimum* 450w, and that's what I have, wanted to share my specs to see if I'm going to run into trouble:

PSU: Thermaltake 450w Black Widow
Output --

+ 3.3v x 24 A
+ 5V x 15 A
+ 12v x 17A
+ 12v x 16A (so I have 2 12v rails?)
- 12v x .3A
- 5vSB x 3A (no idea what negative voltages are for)

Rest of the PC:

Lenovo IdeaCentre K230(5359-3AU) Core 2 Duo E7400(2.80GHz) 6GB DDR2. All I've done with it since buying it was upgrade to Win 7 and throw the 280w stock psu in the garbage and replace with above.

Anyways, would like to buy this card (using Bestbuy because I have a gift card there)

  1. Yes it will run on that
  2. ^ +1 to rolli, that PSU will have no problem running the 4770
  3. Yes it will run on your Thermaltake PSU.
    Actually HD4770 will even run on a quality 400W unit.
    It is an energy efficient card.

    An 80+ certified 450W PSU can even take HD4870/GTX 260.
  4. So here's a noob question:

    I have a 6 pin connector to provide additional power to a PCIe card that is free right now.

    However, there is also a modular 6 pin that came with the PSU that I can plug in. Does the modular 6 pin cord access the 2nd 12v rail?

    Or, should I just use the 6 pin 12v that I have free?
  5. just use the 6pin PCIe

    Thanks, so the Corsair 400W should work fine with the XFX Radeon 4770?
