EVGA SuperNOVA G2 and G3 models are often recommended.</p>

suggests that 80+ Gold and especially 80+ Platinum power supplies are
significantly more expensive than 80+ Bronze ones at low PSU power
ratings, at least here in Canada. I'm not entirely certain I'm willing
to pay the price premium for eg the Corsair CS 550M in order to go from
80+ Bronze to 80+ Gold. On the other hand, it's not a lot of money on an
absolute scale and it's certainly tempting to have a cool and quiet PSU.
I may yet throw restraint to the wind and go for 80+ Platinum.</p>
<p>(Low-wattage 80+ Platinum PSUs appear to often be fanless, which I've
decided I'm not willing to trust to be cool enough in my case and home
environment.)</p>

Affordable 80 plus gold certified PSUs have been available for at least five years now. You might want to vote with your wallet and get one of those, or even 80 plus platinum. Remember that a more efficient PSU is also a quieter one.</p>

<p>Oh, if only. In early 2012 I spent £33 on 8GB of middle-of-the-road DDR3. Today, the <em>exact same</em> memory costs £60, and 8GB of middle-of-the-road DDR4 costs £85.</p>
<p>The machine I built in a hurry in the middle of last year due to a M/B failure is the first new machine I've ever had with <em>less</em> memory than its predecessor. At the time I figured I'd top it up in a month or two, but memory prices just kept going up and up and here we are over a year later and it just keeps getting worse with no end in sight.</p>

supports ECC on any particular current motherboard. Generally it appears
that motherboards will let you put in ECC RAM, but it's not clear
to what extent they actually use the ECC bits to correct single-bit
errors and scream loudly (and perhaps fault with hard machine errors)
on double-bit errors, which is what we actually care about.</p>
<p>If Ryzen fully supported ECC, <a href="https://utcc.utoronto.ca/~cks/space/blog/tech/AMDRyzenOfficeTemptation">I might use it for my work machine</a> but probably not my home machine.
There's part of me that would like ECC at home, but there's also part
of me that wants a 65 W TDP and high performance.</p>
