Hello me fellow bargain hunters.
can someone please tell me if it would be ok to install a graphics card that requires 350w in a computer that has a psu of 305w, would installing the card cause any damage to my computer. The graphics card that i have purchased is a XFX 8600GT 512mb.

Thanks guys.

Don't do it. your computer will likely not start at all or run for a few minutes and then shut down. You MUST have a PSU that's AT LEAST enough to cover everything in your pc.

It's also incremental; if your GPU needs 350w and your sound card needed 150w (for example), then your PSU should be at least 500w. Obviously theres more than just graphics card and sound card to take in to consideration usually.

But surly the graphics card will not need 350w of power?

Depends on the PC, Dell PSU's are alot more powerful that stated on the unit.

My computer spec is 80gb, 2gb ram, sound card is onboard and p4 2.8HT.

Whats the make of PSU in it.

Yep, some are much better quality than their wattage indicates plus it depends on what the specs of the rest of your system are. If it's a good branded power supply then it may well be fine, I'm currently running a core i7 940, 8GB ram, two optical drives, two hard drives, a 4850, pci-e wireless and pci-e audio on a 375W PSU. Previously in my SFF system I had an A64, AIW 9800 pro, 1GB ram, optical drive and two hard drives running on a 200W PSU.

If it is a poor quality PSU though you do risk damaging your system, Anandtech usually have actual measured graphics card consumption although I can't see anything for the 8600.

This is not true - it's not incremental, the 350W figure is a safe figure that Nvidia have calculated based on the power the graphics card will need on top of the power consumption of a PC. They very much err on the side of caution and recommend much higher wattages than are actually needed which will depend on the rest of the system components and the quality of the power supply. The Radeon 9700 pro was recommended to have a 350W power supply, I ran one on a 175W PSU and its successor on a 200W PSU both without issue.

What you're claiming is that the graphics card on its own requires 350W which is not the case at all with an 8600 graphics card, have a look at the chart here:

http://www.anandtech.com/video/showdoc.aspx?i=3539&p=22

This is the total power consumption, you'll notice even the 4850 dual graphics card which draws massively more power than the Nvidia 8600 is still drawing less than 350W power overall.

Im pretty sure you will be ok m8, Dell PSU's are underated , im sure others with better knowledge will confirm

guys i found this site [url]www.legitreviews.com/article/486/15/[/url]

idle is 120 wats
load 188 wats

Guys thanks for the help and advice, i think i will stick the card in and see what happens. The only game that i will ever play is flight sim X.

just found this on a website

"The XFX GeForce 8600 GT is a single slot design that requires no additional power connector for operation. This makes the board very energy efficient as it has a maximum power draw of just 43 watts."
