Right angle connections pointing in which direction? Some PSUs are on the bottom and some are on the top. It would be worse having to connect a right angle and then routing over or around the card to get to the PSU.
If it's angled to the front of the case it'd cover both cases. Interestingly enough the founder's edition (ie: nvidia designed cards) seems to have the connector angled front at 45 degrees. However the non-founders cards in the article have it sticking horizontally to the side like previous cards. Seems something nvidia should have communicated to it's partners.
That could be standardized as well, similar to how form factors for cards are.
You never see a PSU on the top nowadays in personal rigs
If you have a new computer case which isn't a requirement.
I just bought an extremely popular case, the Fractal Torrent. The PSU sits on top.
That’s a new one for me, I thought top mounted PSUs were a relic of the past. I stand corrected
I've been planning to use that case for my next build for months now, but I'm not sure anymore. These hot new components make it look like liquid cooling is mandatory if you value your ears, and the Torrent isn't the best choice for that.
