lol thanks guys. Ok now I'm running into another problem, because my local stores don't have them I'm just going to buy it online but there is a s load of hd 5450 and whats the diff between one and the others besides look (which i wont see because it will be inside the computer )
The Seasonic 300w power supply would be a useful upgrade and allow you to step up to a 5670 graphic card. It's out of stock at newegg right now, but it's a quality power supply and worth waiting for or ordering from a different retailer.
From a review of the PSU
"Pros: Purchased this to upgrade the stock 220w psu on a HP Pavilion Slimline s5604f (also put a XFX PVT95GZAFG GeForce 9500 GT low profile card in the unit.) This psu fit perfectly. My motherboard did not have a "micro" 24 pin connector as HP's sometimes do, so it was just a plug and play. Will update if I have longevity issues.
Cons: Not exactly a con, but the wires are extreamly long, at least for my needs. Stuffing them into a slimline case was a bit of a challenge. Still, I'd rather have to much than to little.
Other Thoughts: Pleased so far."
Just in case you return the 5450....... argggh , i know, but in the interest of providing as much info as i can.
