Video card upgrade for HP Pavilion Slimline?

i have a HP Pavilion Slimline s5610t with an Intel Graphics Media Accelerator X4500 (VGA) that i have disabled and i now have a nvidia GeForce 8400 GS graphics card that i installed....the PSU that came with the PC is 220 watts.....was looking online at a review for the PC and it stated the PC could support 1GB nvidia GeForce 315 card but i cant seem to find it online and im also not sure if that would be an upgrade to the card im using now......any suggestions for a decent card upgrade??....and if i upgrade the card, do i need to upgrade the PSU also??....the PC seems to be working fine with the PSU thats installed but better to be safe than sorry, right??|||Gregory is way off base. Your processor draws 65W, motherboard 35W+, = 100W, not counting memory, hard drive, dvd drive, keyboard and mouse. Besides, a 120W card would require a 6 pin pci-e power connector that your power supply doesn't have and wouldn't be able to support even if you used a molex to 6 pin adapter.



The GeForce 315 is an 'oem only' card, not available for individual sale.

HP offered the GeForce 315 (max power draw 33W) and the HD 5450 (max power draw 20W) as possible graphics upgrades for your system.

In benchmarks, the HD 5450 is rated slightly higher than the 315.

Without a psu upgrade, I wouldn't recommend using a more powerful card than those. That system uses a psu with a small ATX 24 pin main motherboard connector, so you can't use just any TFX power supply, the psu upgrade must have the small ATX power connector.



Here's a 270W upgrade.

Here's the same psu at better prices. Disregard the references to 300W, it's a 270W psu.

I would suggest that you find a psu that is 100w over your new card
