Market-wise, it does make sense to see 8 pins on cheaper cards. On the low end its likely someone is trying to save money such as by not updating their PSU.
Nope, not happening. We're waaaaay past that. I steered from the 7900XTX thinking its high power draw was over the limit for my 750W, a 2009 era part.
Then I underestimated the 7900XT until I had it
in this system and no POST. Hemmed and hawwed over it a bit
for months to figure it out.
Help desks across the board (ASUS, AMD, PowerColor, newegg, etc) all BTFO. They lost the plot then PowerColor tried scamming me out of a return.
So, as hinted above, I haven't built a new system from scratch in a REALLY long time. What I build for myself and others is often recycled.
~Sept 2019, this Ryzen box was just me scratching together CPU, mobo, memory and a M.2. After a month of piecemeal, done.
I reused my case, power supply and GPU to get everything running again.
There's a lot to watch out for when parts are 7-10 generations behind but when enthusiast cards:
Fail detection and nobody has any idea what's wrong ("oh it's DOA, return it...")
The same behavior keeps happening with
multiple units
The ultra specific hardware failure code (1L4S) doesn't kick off
...Maybe DOA isn't it. It should have been obvious to every builder and literally everybody supposedly trained to catch it completely failed.
We can no longer scratch together systems from old parts. Not when everything is "AI" and spikes more than the entire system power profile.
The really stupid part is how I had to go back specifically to PowerColor's site and confirm the power requirements on their product page.
PowerColor is a vendor, NOT the retailer. I'm not going there for information unless I absolutely need it. I didn't find this ANYWHERE else.
The requirements should be detailed by retailer. So once again, total communication breakdown. This is what confirmed the problem:
Dual 8-pin and 12VHPWR can deal. What can't is every antique power box with a 25A rail and the retailer just assumes you have better.
We are still in that weird transition period where people need to catch on. I've been around for a very long time and this snuck right by.
I also keep finding 25A rail power supplies at worse prices than the stuff that works. There is ALL kinds of junk out there that will ruin a build.
So how well is the 9070XT going to deal with the same problems? It won't. I'll be real, seeing leaks of the core, it looks like a pair of smaller dies.
The power consumption behavior could get real nasty under overclocked loads. Is ASUS going to tell us that? How about MSI or ASRock?
It's gonna be PowerColor
again and it's going to be the same communication breakdown
again. Good luck nobody.
