Windows 7: Can my PSU support it?

Bullshit, tdp tells nothing most of the times, if that 400w psu is not some cheap plastic bucket full of shit then it's gonna take that load just fine.

I'm still using 520w with my gtx 480 and you can look up what's the suggested amount of watts psu should have and it's probably way over 520 and then theres my overclocked q9550 and other stuff.

I'd just say thread closed and problem solved but that'd be ignorant

But why do you want to "downgrade" from a 2.7GHz CPU to a 2.5GHz CPU. Don't expect too much from the 4 cores because most programs will not be using them. I am very disappointed with my quad processor. My slightly faster duo core is better.

PS: The wattage was measured by a German computer mag
That must be a total system power. The 9850 is rated at 125W TDP.

AMD Phenomâ„¢ Model Number and Feature Comparisons

The 9500GT doesn't use any auxiliary power connectors, so it must use less than 75W (rated max. of the PCI-E slot). The 50W max listed by another poster sounds right.

PSUs vary a great deal. A good 400W one can supply more current at +12V than a cheap 600W one. What make is your PSU? How many amps at +12V? (See the sticker.)
My 12V rail gives of 24AMPS. Its a Ultra LSP450W PSU

As WHS has stated processor speed is more desirable than how many cores you want. As a builder I always suggest to the client whats your system going to be used for? Quad/Dual are beneficial if you are performing advanced applications eg: massive db/spreadsheets, video etc. Also I always advise clients during the initial phase to always purchase a higher wattage psu to start with because during upgrading its better to have more power, if you are looking at it from a gamer point of view then processor speed is where you want to look.

That's not bad. An expensive 450W PSU has 36A at +12V.

(Newegg.com - SILVERSTONE ST45SF 450W SFX12V 80 PLUS BRONZE Certified Active PFC Power Supply)

A cheap one, 17A:

Newegg.com - DYNAPOWER USA EP-45X.0562B 450W ATX12V, Version 2.2 Power Supply

If you stay with a 9500GT, you ought to have lots of margin:

EVGA | Products 9 Series Family&sw=

(Single 9500GT: 350W, with 18A at 12V).

eVGA claims that you'd be OK with a GTX460:

EVGA | Products 400 Series Family&sw=

That's a much hotter card, in every sense of the word.
