Any suggestions for a type power supply upgrade?

I have an HP Pavilion Slimline s5 1128p PC. I know this isn't a suitable desktop PC for gaming, but its what someone bought me. I want to use a Radeon HD 6450 PCI-E 2.0 x 16 graphics card. I need a minimum of 400w, I would feel safe with 500w. I'm having trouble deciding what type of power supply is compatible with my motherboard and processor.
Here are my specs:

Motherboard -

Form factor: uATX: 24.38 cm (9.6 inches) x 24.38 cm (9.6 inches)
Chipset: AMD Hudson-D2 FCH

Processor socket: FM1
Expansion Slots:

3 PCI Express x1
1 PCI Express Mini Card x1

Processor -
AMD A4-3400 APU with Radeon(tm) HD Graphics 2.70 GHz

Current Power Supply -
Form factor: Internal for slim form factor
Total wattage: 220W
Nominal input voltage range:

100-127V/6A (50-60Hz)
200-240V/3A (50-60Hz)

Dimensions: 200mm x 85mm x 53mm (7.9 x 3.3 x 2.1 inches)
Help would be greatly appreciated! :D

  1. That power supply's dimensions are proprietary. I don't know that you're going to find an aftermarket PSU that'll fit in its place.
  2. Well I found this: Shuttle Computer Shuttle PC63J

    I'm confused as to whether the brand of power supply matters in terms of being compatible with my motherboard. Shouldn't I be able to use any power supply as long as its fits?

    I posted a power supply that has near perfect dimensions ...
  4. good find! Where'd you find it?
  5. 1) Still not convinced that power supply will work
    2) The Radeon 6450 is a very low power unit and will probably work with your existing 220w psu. You certainly don't need 500w.

    Yea I thought the Radeon would work at first based on some research I did. However 220w is really low and I read that games such as Skyrim wont run well. In order for it to run smoothly, a power supply of 400w is recommended. At least that is what the seller recommended for that specific graphics card.

    Here are my specs:



    minimum 400w is crap. ive installed many ATI/AMD 4350/ 5450/6450 on slim line PCs (make sure you get the low profile card that comes with a low profile bracket). at peak it only uses 26w, at stress a 2500k PC does not break 160w with the amd 6450
