Need help with power supply

[vanquishedangel]

Hi and thank you for reading my post.

I have a hp dc7100sff that i have upgraded before and I am upgrading it again. The stats are as follows

Video: ATI Radeon 4350, 512 mb vram

Processor: P4 3.8 ghz ht (intel 670)

Ram: 4gig High density

Drives: 1 80 gig MDT MD800jD-00MSA1, 1 40 gig WDC WD400BD-75MRA1, NEC dvdrw ND-3450A

Operating system: Lubuntu 64bit 11.04 Natty Narwhal

Power supply: 240 watt

I am adding a 3.0 usb card that has only 1 usb port and is a pci card. Another card that is a compact flash card adapter that holds 4 cf cards and it has raid abilities that is also pci will also be added. Neither of these need a power source other than the pci slot. The compact flash cards will be used as swap space in linux (faster than hd space) so they are only 1 gig each.

Will the 240 watt power supply be good enough? if not what are my options here? If you can please post links.

Thanks in advance

It should be good enough, as those cards will draw very little power, i.e. combined we're talking less than a low-end discrete graphics card.

everything is pretty and even more ... but I do not know that efficiency 240W PSU, is it really 240 or just a label ...

If it works now, it will continue to work, but you're still cutting it pretty close.
