Intel DP45SG and Radeon HD 5450 No Video

coco3431 · Jan 20, 2014

I bought an Intel DP45SG and a PowerColor Radeon HD 5450. The radeon is pcie 2.1 and the motherboard has pcie 2.0. When I boot the computer the fans come on but I don't get any video. I know the board works because I tried an older card and it worked. Maybe there is a setting in the bios that I missed? I read that they should work because 2.1 is compatible with 2.0. If anyone had any ideas or if I am misinformed I would greatly like to know.

Thanks!

they should work together. perhaps the power supply in the PC can't power the card? Just wondering what PSU you've got.

Have you changed the video output sequence in the bios to give priority to the 5450 (PCIE) from VGA/onboard ?

PSU not at fault, as the 5450 uses less than the 75w that the PCIE slot can provide.

My power supply is a dell power supply, I had not even though about it but when i looked it up it is 250 watts, might be the problem. This board doesn't have on-board video, but maybe there is a setting anyway?

out of curiousity what was the older card.

Ati Radeon HD 5450 requires 400 Watt or greater power supply.

HD 5450 and HD 6450
■400 Watt or greater power supply recommended by AMD

The older video card that I tested it with is a nVIDIA Quadro 280. I will have to see if I can find a power supply to test it with to make sure.

http://www.amd.com/uk/products/desktop/graphics/ati-radeon-hd-5000/hd-5450-overview/Pages/hd-5450-overview.aspx#3 - full spec requirement for 5450 does indeed say 400W or more.

here's a review that recommends atleast a 360W output from the PSU.

I just tried a 400 watt power supply and it still didn't work. I have two of these builds doing the exact same thing, so I would guess that it isn't a bad part.
