Next we want to try Cross Loading. This basically means loads which are not balanced. If a PC for instance needs 500W on the +12V outputs but something like 30W via the combined 3.3V and +5V outputs then the voltage regulation can fluctuate badly. Cross Load Testing

I would power limit the 4090 to about 70–80% as a good start. Cyberpunk seems a good one to load up especially with heavy RT enabled.

80 PLUS PLATINUM CERTIFIED

Due to public requests we have changed our temperature settings recently – previously we rated with ambient temperatures at 25C, we have increased ambient temperatures by 10c (to 35c) in our environment to greater reflect warmer internal chassis conditions. I have many power pig cards and I found the single cable and pigtail combination works with cards want three PCIe cable connections.

To my knowledge, the cables are interchangeable between all SF series PSUs, as well as some RM units iirc. Sometimes I will game on the TV which is 4K 120Hz, but that's only for the odd controller oriented game Efficiency is excellent, peaking at just over 94% around 50% load. At full load the power supply maintains a 92.7% efficiency level, which is impressive. Would i get another? I don't know, i know they're Seasonic OEM's... a majority of these SFX-L's are hence all sharing the same problems. I will do my research if i upgrade again and see which ones are OEM's from which manufacturer and decide from there on like i did with this one.

The SF750 has only 2 PCIe splitting in two connectors. So is there a difference using 1 PCIe and 1 PCIe splitted in two and on the other hand using 3 discrete PCIe cables? I mean do I get more wattage with 3 separate PCIe cables or doesn't it matter.

Additionally, as we would expect in this price point, the SF750 is a fully modular power supply featuring very high Platinum efficiency certification. This is a standard sized SFX chassis too – its not one of the extended length versions we see from time to time from other companies. We like the box artwork for this power supply, all the key points are listed along the bottom at the front of the box, along with a quality high resolution image in the middle. 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? I do not want to void the PSU warranty but with that high temperature 24/7, it seems either use the warranty soon or void it :P The Corsair SF750 SFX Platinum power supply is rated to deliver a combined, continuous output up to 750 watts at up to 50c. It is based around a single rail design that can deliver up to 62.5A (750W). No problems here. 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. Under higher load situations, the fan will spin, but until you are close to 80% load, it won't really make its presence known. At full load, the fan is quite noisy but we would expect this – after all it is still only 90mm in diameter.

Typical Apple Innovation…

OVP (Over Voltage) | UVP (Under Voltage) | SCP (Short Circuit) | OTP (Over Temp) | OPP (Over Power) Peripherals: GK61 (Optical Gateron Red) with Mistel White/Orange keycaps, Logitech G102 (Purple), BitWit Ensemble Grey Deskpad. Today to test the power supply we have taken it into our acoustics room environment and have set our Digital Sound Level Noise Decibel Meter Style 2 one meter away from the unit. We have no other fans running so we can effectively measure just the noise from the unit itself. What Amazes me is the price of an extra PCIe cable is like 20% of the Price u pay for the SF750+included cables. Depends entirely on the whole combination. Can get power hungry CPUs and power hungry 3090's / 3080Ti's that go well above FE at times when OC'd.
