Have one of these, well worth it. I think the Platinum efficiency helps it stay cooler and quiet.

Doubt it.

Just not sure how more efficient Plat PSU will be vs Gold equivalent £20 cheaper.

In a small form factor machine, which these are for, efficiency is more important as it's harder to dissipate any extra waste heat. In an ATX case I'd not be bothered and would even be happy with bronze efficiency providing it was otherwise a quality PSU, in an ITX case it's a different matter.

I have been using the 600w version for about 3 years and it's excellent.

Considering whether to upgrade to be a bit more futureproof...

Same and came here to see if anyone was having this idea, not disappointed

Cool find

I wish 450 for under 100

Buy that nzxt mini itx case, it's on offer for £100 and comes with a 500w psu. Then sell the case and keep psu.

Not enough juice for ge force 4 series. Thats ok though as in this economy not many can afford it . (edited)

It'd probably be fine for some of them, the key point with this power supply is that it's SFX, it's considerably smaller than average so it'll fit in small/custom builds where a normal ATX PSU won't fit, and this wattage and spec are pretty high for that form factor

Especially at a not insane price. (edited)

Currently use one of these in my SFF build. Great PSU. Mine is paired with a 5600X and a 3080.

This paired with a Lian Li mini would be circa £210. Not bad. Anyone doing that?
3rd Dec
Yes, I have one of these in an O11 Dynamic Mini, paired with a Ryzen 5800x and an RTX 3080. Don't think I've ever heard the fan spin up, this PSU is excellent
3rd Dec
Using this in a SFF build, don't think the fan has ever come on, but I'm not using a graphics card I just wanted a platinum supply and don't think there are that many.
3rd Dec
I think I will bite at £100, currently have a RM750X but airflow will be much better with this

Replaced the noisy PSU in the Razer Core X Chroma with this, now very quiet even under load. Quality PSU and braided cables.

I still have 760 Watt 80 PLUS PLATINUM which is still going very well.

Seems like a great price to me, I have been watching this for a couple of weeks, and lowest I'd found was £142 at Amazon, who were pricematching someone else, or £140-141 on eBay.

However, I dislike Corsair as a company, since they don't stand behind their products. So today ordered an Asus ROG Roki 750w SFW-L, which is likely going to be quieter, and it's PCIe 5.0 / ATX 3.0.(186 on eBay, using the NOW15 code)

However, the Corsair is cheaper and reviews shows it has pretty awesome perormance; making it a solid choice if you don't mind Corsair products.
