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 -
Manufacturer: Pegatron
Form factor: uATX: 24.38 cm (9.6 inches) x 24.38 cm (9.6 inches)
Chipset: AMD Hudson-D2 FCH
Memory sockets: 2 x DDR3
Front side bus speeds: 100 MHz UMI (Unified Media Interface)
Processor socket: FM1
Expansion Slots:
PCI-Express Generation 2 speed

1 PCI Express x16
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

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.

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?

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
