The safest way to know for sure is to open up your PC and do some measuring. Measure the dimensions of your existing power supply. The standard ATX PSU is 5.9" by 5.5" by 3.4" give or take a few of tenths of an inch. Do the same around the PCI-E x16 slot. The GTX 460 is a double wide card so the slot next the card must be open. The GTX 460 is 8.25" long so make sure that length is OK.
Corsair is a good brand.

Thanx. one further question. I know for sure i only have 1 PCI-E x16 slot. Does that mean I cant use the GTX460 since its a double?

The GTX 460 only takes one slot but it's double wide in width going towards the next slot. All of the better video cards are double wide.

Ah I see I see. That makes more sense. I'm pretty sure I have enough room as I have a after market vid. card in there now and it has plaenty of room around it. There really is alot of space in the case since I have room to put in another dvd-drive, and 2 of the smaller floppy type drives. I just like to make sure...thanks for the measurements that will come in handy!

You should open up your PC and measure the physical dimensions of your power supply. Here is a list of things to consider:
- Total wattage - important
- 12+ volt amperage rating - important
- Modular - not mandatory but I like the flexibility
- Efficiency rating
- Physical size -- standard ATX PSU is 5.5" by 5.9" by 3.4" give or take a few tenths
www.newegg.com has lots of PSUs choices. Corsair, OCZ, Rosewill, Thermaltake.....

I have a a6554f and want to upgrade videocard to a Xfx Ati Radeon Hd5750 1gb Gddr5 128bits
this card needs at least 500 watts i think, do i need to upgrade my PSU also? or my a6554f supports
this video card?
