The Loki's apparently have bad coil whine and the newer Corsair are apparently loud and come with crappy cables but also new connectors so changing the cables is a faff. If games use 150w and the GPU pulls 450w there should still be headroom as the SF750 is known to be decent spec. Before the release of the SF750, the SF450 and SF600 Platinum had been introduced, making the competition feel awkward.

Correctly testing power supplies is a complex procedure and KitGuru have configured a test bench which can deliver up to a 2,000 watt DC load. From what I've read, when gaming the 4090 pulls approx 350w, so that's only 20w more than my current 3080 however the odd game does pull more at times so can anybody tell me which games to test this with. We can see that the 750W version also ships with 2 4+4 Pin EPX/ATX12V connectors, a great addition to see.

I think the only way I am going to be able to push the CPU up to 280w whilst playing a game is to have something else (like encode a video) in the background.In the SF750, the fan will start to spin at some point, but internal heat build-up is quite significant until it does, which puts a lot of strain on such sensitive parts as the electrolytic caps of the secondary side. Shame your having issues as there's been some glowing reviews, which I assume you saw and help with your purchase decision on it. It did for awhile but i gave it another chance and decided to wear one in by just using it and its gotten alot better to the point where i don't notice it at all now.

ASRock's Radeon RX 6950 XT OC Formula is one of the fastest RX 6950 XT custom designs we've reviewed, and its great cooler achieves excellent temperatures.

There are a total of eight individually sleeved modular cables in the box and there are plenty of connectors to cater for the majority of enthusiast system builds. Although with 150 W less power output, it achieving better performance in some areas isn't surprising, like load regulation on the minor rails and ripple suppression.

At 750 W, its power density is ultra-high, capable of supporting a very strong system equipped with power hungry components. Previously the SF Platinum series shipped in only 450W and 650W capacities, so this new high model will appeal to the hard core enthusiast user looking for a high wattage small form factor supply.

I noticed the SF750 has 2x GPU cables and 2X CPU 8 pin cables which kinda make no sense for an SFX PSU.

If you can't see the image gallery above then you will likely need to white list us in your ad blocker as they are known to interfere with our display code. Sorry for all the questions and bad structure, i'm just wondering what i need to do to prepare for my upcoming card.With the bundled SFX-to-ATX adapter, users can use this PSU with a normal ATX chassis, but the short cables set the limits here. assuming it is, can I swap the modular cables only at the PSU side or will the cables be different gauge wire? I am wondering is there any way to control the fan of a Corsair PSU without dissecting it and putting a Noctua which will be powered by the MB? It is likely if you have this supply in your system and you are doing general work it won't make a noise at all. The layout, construction and overall design is very similar to the SF600 model in the range which we had a look at before.
