8800GT 256mb with a 430w Tagan

  1080p 13:10 03 Nov 2008

Hi guys,

Quick question, will the following be ok with a 430W Tagan PSU with 20A 12v rails?

2x 500GB HDDs
1x DVDRW lightscribe
Core2Duo 1.8ghz 2mb L2
Card reader + 6 usb
8800GT 256mb (yet to be purchased)

Many thanks

from memory nvidia recommend 26amps combined 12 volt rails. you're cutting it very fine anyway IMHO.

The PSU says 28AMps combined

hmm, maybe I should opt for a slightly older 7900gt then - or perhaps take it back to 2GB of ram, would that help?

You're right about the combined rail requirement:

"A minimum 400W system power supply (with 12V current rating of 26A)"

However that is for a 512mb, will the 256 need significantly less juice?

i am probably the wrong person to ask, i used a cheap (within recommended specs) psu some years back with dire results. i now respect what the psu does and the damage it can cause. i think you're just within spec but it's a risk i wouldn't take. i think (not sure) that the old 320meg 8800gts and 640 meg had the same min specs, or were similar. i cant see ram being too greedy.

as it is a decent make of psu it should be ok.
