I purchased a Sapphire Vapor-X HD5750 to replace my ATI x1300Pro. MSI MB has onboard graphics as well K8NGM2-FID.
PSU Mad Dog 525W.
When the HD 5750 is installed the pc will not post and no video signal. BIOS settings are set for non-quick boot and I should here a short beep after post prior to loading windows. I drives spin looks, HDD lights are on, but then go out and never hear a post beep.
Removing the HD 5750 and either powering on using the onboard or inserting the old X1300 PC will post with video and beep occurs.
Narrowed it down so I get video via component cables from my onboard video whether or not the X1300 is present or not. Without changing any BIOS settings..inserting the HD 5750 yields the no signal, no post result.
The fan on the HD5750 powers on and the Blue emblem on the side of the Vapor-X heat sink lights up. Though dims just after power up (is this normal due to load)?
Looking at the digital readout on my Back-ups unit...load display during boot appears similar whether the HD 5750 is inserted or not inserted. The highest number that it looks like it gets to is 240W...but is typically at 170-180W.
I am not certain if the new card is no good or if my PSU is not up to snuff. I plugged most of the items and then some in the calculator here: http://www.thermaltake.outervision.com/Power
and I see 342W. Now of course I wouldn't believe the Mad Dog PSU unit I purchased from CompUSA a few years ago is really 525W...but I am inclined to think it should be enough. I believe the label said it 250W on the +12v rail.
If the power supply wasn't enough for this card wouldn't it still post?
