Power Supply Question

[mattaggie]

I am building an HTPC. I bought this case
http://www.newegg.com/Product/Produc...82E16811108092

It came with a 300 watt PSU. I also bought this Antec PSU http://www.newegg.com/Product/Produc...82E16817371002

But the Antec PSU does not fit in the case. So my question is, is the PSU that came with the case big enough in terms of wattage? It is a FSP Group Inc. I know most of you typically do not like PSU's that come with cheaper cases. How do you know what size, in terms of dimensions, a PSU is? I didnt really know there are different sizes. If I wanted to buy a better PSU that fit my case, how would I know it was the right size?

1 stick of DDR21066 RAM
640GB HDD
SATA Blu Ray drive
AMD Phenom 8450 Toliman 2.1GHz Socket AM2+ 95W Triple-Core Processor

I used a PSU calculator online and it said all I needed was around 180W

The 300w should be ok. FSP is a great quality brand.

If you want to upgrade the power supply, you'll need the "SFX" type. They are smaller then the typical ATX form.
