Getting a XPS 8300 do I need to upgrade PSU?

I'm getting a Dell XPS 8300 delivered early next week. It comes with a 460 watt psu. Was wondering if I need to upgrade it with the stuff I'm putting in it? Or would the 460 PSU be fine? Here are the complete specs:

Intel i7 2600
Samsung 830 128 SSD
1tb 7200rpm HDD (not sure what model, Dell doesn't say)
16gb Corsair XMS3 DDR3 Ram (4x4GB)
EVGA GTX 550 TI 01G-P3-1556-KR
DVD burner (not sure what model)
Lite-On IHBS 112-04 Blu-Ray burner
USB 3.0 ports in the PCI-e X1 w/ 4 pin connector

Maybe an external HDD hooked up to it also.

If I need to upgrade would something like Antec EarthWatts EA-500D Green 500 Watt be good? What would you guys recommend?

Also, If i were to upgrade, could I put the XPS 8300 460 watt psu in a older dell inspiron 530(Core 2 Quad Q6600). The dell inspiron 530 psu seems to be dying.

Thanks for all the help. These forums have really helped me out alot.

  1. Hi :)

    The PSU will be fine...average psu for average machine...

    All the best Brett :)
  2. Its hard to find much information about Dell power supplies, but some of them are made by Delta which is one of the very best suppliers and all the XPS psus have good reputations. I happen to have that same system, currently running a 560ti 448, overclocked and absolutely no problems. Whole system maxxed pulls 300w from the wall. The Antec 500 might be an upgrade and it might not...if it is still the same model that is also made by Delta, so it may or may not be an upgrade over the Dell. In any case not a big enough upgrade to be worth the hassle. If you have a another psu that is dying, replace that with the Antec or for $10 less you can get a Bronze Seasonic 520w from Newegg, another excellent choice.
  3. Thanks for all the help guys. I will definitely leave it as is then. :)
