... Overclockers might be more expensive ... but they're generally there or there abouts. But literally NO-WHERE can match the price that they have on the monitor I just spoke of (above this quote and here) ... plus you are buying from a British company, so your money will more directly go back to where YOU need it when YOU need it.Overclockers are generally more expensive than elsewhere, Scan are better, and good tech support, Amazon has however always beaten them all on price and been easy to chat with someone and returning goods even if your nan just looked at them wrong!
The point is ... pay a little more, have WAAAAY better service. Plus you can phone through and speak to them about everything, and likely knock them down some if you can show that (for example) Scan are offering something comparable for the same price. Also ... it's not just about returns ...... for the sake of a few more quid (or often the same price or less) you can buy ...
All this said ... I am a TOTAL Scan-stan, though, and would stand up for them through thick and thin. They are **EXCELLENT** ... there is no other word for it ... I would ALWAYS say buy from them ... but I was trying to appear balanced.
I'd say that you're fine with it for the OS drive, and even for the games drive ... but it's good to separate your games drive from your OS drive, anyway ... just to not tie the games to a drive that will have a lot more write actions on it like the OS.
Also, it gives more potential to utilise (for example) a steam library in another Operating System.
I think that only the most modern, open world, games, will benefit from GEN 5 speed ... but I could be talking out of my arse, there.

Don't chicken out ... get on this tomoz ... and don't give up until things are running good! 🙏

Full loop yeah, but an AIO can help your CPU boost higher and do sustained loads for longer than an air cooler, https://www.amazon.co.uk/ARCTIC-Liquid-Freezer-III-RGB/dp/B0DLWFCVSD is a brilliant bang for buck cooler (and cheaper than some Noctuaswater cooling is a fad, air cooling with a proper case is the way to go and costs a fraction of the price
Those Molexes plug into the modular PSU and go to 2 x 8 GPU headers. They’ve powered a 980ti and a 3060ti before. Overclockers built thisas a mid-range system with it as the base so they are half decent.In agreement with @Ace`, @pooman2084, mate.
Also ... Make sure you're using the correct cables from the PSU MFCTR for powering *anything* because sometimes they'll often also have different pinouts.
( sorry if this is all 'sucking eggs' nonsense ... please do ignore me if it is! 😅 )
