Hello Forum,
My PC is an HP DC7800 MT and I'd like to add this ECS GeForce 9800 GT video card.

~~(ecs site seems to load very slow)

I realize similar cards recommend a 400W PSU but neither page for this card mentions anything about PSU's. Also it claims 40% power saving. So do you think this video card will work fine with the 365W PSU in my PC?

The ECS N9800GTE-1GTU-F draws all of its power through the PCI Express x16 slot so its power consumption is under 75 Watts or less than 6 Amps from the +12V rail.

Your 365 Watt HP OEM power supply should have a combined +12 Volt continuous current rating of at least 22 Amps.

You shouldn't have any problems powering your system with that graphics card.

i would suggest that you get a 550w ( a bit higher is better), a good one, not some cheap 550w.
it will help you in future upgrades. get seasonic or corsair or other good brands.

also, remember that capacitors do age, so they grow weak as years go by. a good psu is a sound investment

If your PSU was actually rated 365 watts of continuous output, with a real amount of amps on the 12v+ rail, it would be plenty. However, being a "factory" PSU odds are very high it's not up to the task . As the above poster mentioned, I would just buy a nicer 500-550 watt PSU and have it to use in future upgrades/builds. A quality 550 watt PSU, rated for 550 watts continuous is plenty for most new builds.

I have one in one of my PC's with P4 no name PSU and Athlon X2 5200+. It works for three years without any problem. It's not total power of PSU that is required, it's how much it can provide on 12V rails. It should be written on PSU.

Also. This card is power saver because it will downclock itself when idle and not needed. And you can achieve that with GPU and some software.

Thank you to everyone for the help.

I had a standard ATX 500W PSU but it will not fit the HP form factor. The highest W PSU I could find is this ATX 480W modified to fit.

So, Thank you for the realization that this video card draws power from the slot. Now I am sure it will work and I won't have to buy that 480W PSU, but I will probably will get it sometime anyway.
