Anyone had suggestions for a good power-supply?
The one I wanted is currently both overpriced and out of stock everywhere.
Make sure that the brand you buy from is well-known and not a Taiwanese knock-off, but other than that, I don't think there's a
real orthodoxy on brands. I've done great with my SeaSonic, which at the time I got it was a highly recommended brand, but I found some other people a couple of years ago trashing it and saying they had a terrible experience with one. It's been my observation that that's the way with all the major brands, if you cast a wide net.
There's three general principles that I've gone by which have served me well:
1) Buy a PSU with 50% more power than your parts added together, because parts have power usage spikes beyond what they're normally listed for, and that will provide a safe overheard for that never to be an issue.
2) Look for 80+ certification. The certification is about power efficiency, but
in general, a Bronze level or better certification means that the PSU had to have enough care put into its design and manufacture to attain certification that it has a good level of build quality.
3) Do not buy used no matter how good the deal.
