Hi all,

I'm picking one of these up for my brother (got him a new motherboard & cpu... but don't tell him!)..

http://www.xoxide.com/20-to-24-pin-adapter.html

Are there any issues with using an older 20 pin psu with a newer motherboard that I should know about?

Thanks!

Hi

With the ATX 2.0 standard motherboards (with 24 pin connectors) the standard is backward compatible with ATX 1.3. Which means that you can plug in only one way an older PSU by leaving 4 blank holes and it'll still work. I've done this with a DFI and an Antec 430W before perfectly.

I'd get an adapters like this one: http://www.xoxide.com/tt-psu-adaptor-cables.html

Perfect for both. Its done regularly by gamers without any problem. The only issue I've seen is with a Seasonic S12-600 which gave lower voltages when using the adapter than when not, but it was still quite within the accepted range. However, some have encountered problems while many have not. I know I haven't.

I hope it helps. :smile:
