Definitely go for the gold one, much better PSU for only a couple of quid more.

I wouldn’t spend £100’s on components and then put a bronze rated PSU in to power it all.

I'm a total noob with these things, so can I ask why?

Higher efficiency and usually better build quality. You'll save the difference in lower electricity bills, at least between these two corsairs

Seriously? It's that much different? Wow. How much saving are we talking here? I'm looking at building a PC and been out of PC building fir about 15 years. Then you just got a PSU, with the case, lol

They're either mistaking the 80 Plus rating for a stamp of quality (it isn't; it's an efficiency rating), or they're assuming bronze rated PSUs are always bad quality and gold rated PSUs are always good quality. The latter isn't correct either. Gold rated PSUs tend to be better quality. But it isn't always true and there is some overlap (mostly from old models that are still on the market).

As for efficiency itself, comparing the CX-M to the TX-M, the TX-M will deliver roughly:

4% better standby efficiency.
7% better low load efficiency.
4% better typical peak load efficiency.
5% better efficiency under stress.

To translate that in to money, if you ran a PC for 100 hours, you'd expect to save around 8.5p per 100W of load by using the TX-M over the CX-M.

You can't go wrong with either the CX-M or the TX-M really. Both deliver their rated power stably, and within accepted limits for ripple and noise. Both have the appropriate safety features. And both are reliable. The TX-M is just a bit better at everything than the CX-M. So with such a small price difference, the TX-M is undoubtedly the better buy. But if there was £20-£30 between them... it would be worth giving some thought as to the tangible benefits of buying the TX-M.

Thanks very much for taking the time to explain all that, really appreciate it. Feel much better informed about my choice. Will be buying a PSU this week so that's great timing for me, cheers!
