XFX 6800GS Power

[The_K]

How much power is required to run a XFX 6800GS ? Is 300W enough? I have 3GHz P4, 1gb ram, 1 HDD.

Enough to be a succesful politician in a small rural town.

300w isn't enough if it's a no-name psu.

y?

no name PSU's are unstable and generally dont meet the requirements of most of the hardware plugged into them, i learnt the hard way when my 350w wasnt supplying enough amps on the 12v to the hard-drive, which causes the circuitry to fry, luckily i needed another 160 so i ordered the same one, replaced the broken circuit board with the new one's and retrieved all my data, and then RMA'd the other one.

Just to give you an example - P4 3.2ghz @ 3.6Ghz, 4 very busy drives (2 SATA, 2 PATA), XFX 6800GS @ 16/6, PCI TV card, PCI Audigy Platinum with front panel, 6 fans, DVD-RW, network running, 3 USB devices present - all that at this very moment draws 160W flat. When gaming it rises up to 195W. You'd imagine any 400W would handle that without any issues. Standard issue no name 420W power supply couldn't. Machine would reboot not only if I tried to play games but even when I was defragging all 4 drives in the same time or if I tried to burn DVD. It just couldn't provide stable enough current at half it's nominal wattage. Opted for 600W branded PSU and all problems were gone immediatelly.

Mines running on a 250w PSU, no power problems.

A generic no-namer PSU? Or is it a shuttle psu/similar?

 

[peetee]

shuttle PSUs seem to be pretty good, i guess barebones dont really need very powerful psus(cept that SLI shuttle) since you can only really fit single slot cooling graphics cards in, and not many drives or expansion cards either. Plus if your PSU goes haywire and fries your motherboard in a shuttle its them that has 2 pay the price since mobo+PSU are both under their warranty :d

my LE ran with a 400 generic, but wasnt reaching full optimal running power, changed to a 350 watt enermax coolergiant and i gained 300 marks in 3dmark, so a 350-400 decent supply would more than likely work a treat mate
