Where are you getting the 450 from?
"Emachines Et1352-53 mini-tower desktop"
The ET1352 series desktops have a 220 watt power supply. Pitiful.
This excellent third party web site says this is probably a picture of your mboard:
However, he has no info about it.
He would appreciate it if you contact him and tell him what he needs to know.

Home page for his web site:
If the mboard has onboard video - video built into the mboard....
- when you install a PCI-E video card in the PCI-E X 16 slot, the onboard video will probably be automatically disabled by the bios
- when you install (only) a PCI video card in a PCI slot, the onboard video will probably NOT be automatically disabled by the bios
If the mboard DOES NOT have onboard video....
- when you install a PCI-E video card in the PCI-E slot, or a PCI video card in a PCI slot, you should get video.
If you DO NOT have video now yet you did previously, it's LIKELY the power supply is failing or dead!
Emachines desktop computers usually have BESTEC power supplies - they have a reputation of malfunctioning or failing completely A LOT more often than average, and they are A LOT more likely than average to damage something else while doing that , usually the mboard.
If you DO NOT have video now, and if your video adapter is still installed, try another used power supply with your mboard, from another computer you have or from a computer of someone you know - you can probably use any standard sized PS - if you still get no video it's likely the BESTEC power supply fried your mboard !!
If your video DOES work now and you want to upgrade it.........
- you are probably going to need to get a power supply with more wattage capacity. There are VERY FEW video cards that you can install that can be used on a system with only a 220 watt power supply. There are lots of video cards you can use if the PS capacity is 350 watts (output) or more.
Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.
If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.
If you need to get a PS with more capacity, you can usually replace it with any decent standard sized standard ATX PS.
Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.
Don't buy an el-cheapo PS.
Don't buy a BESTEC PS !!!
