In practice, I myself ran an MSI Twin Frozer GTS250 1GB on a board with the 1.0 PCI-e version. The board was Fujitsu Siemens D2317-A1, made in 2005-2006 or so. It had the 1.0 PCI-e version only. 2 Link to comment Share on other sites More sharing options...
The Great Sephiroth Posted June 18, 2023 Author Share Posted June 18, 2023 You might be right. I read somewhere that those first PCI-E 2.0 cards (like 8800 GT) have different/worse PCI-E 2.0 implementation and can't fully go back to PCI-E gen 1. Later GPUs may have different/better PCI-E 2.0 implementation and may go down to gen 1. So I read. Would have to test this. Link to comment Share on other sites More sharing options...

So any *good* and *new* PSU is only 82%, at best. Some expensive declare 85% efficiency, so these calculations are for a mediocre 500-550W PSU. 2 Link to comment Share on other sites More sharing options...
