SP 850 80+ Gold, Black Color, Performance SFX Form Factor Power Supply - SP850 Black

SP 850 80+ Gold, Black Color, Performance SFX Form Factor Power Supply - SP850 Black

Q: Can this power a RTX 4090 with the included cables?

450-500 Watts ballpark on 4090 of course the manufacturer of the card is a factor due to customized bios and power delivery but if you take in your entire PC , processor, accessories 750 could be pushing it close. Personally in my rigs I tend to lean at 200 watts above needed that way my power supply is not pinned at max. Recommend looking up a units "continuous power output" as units can sometimes display max "peak" wattage . Example 500 continuous 750 peak. Manufacturers differ on small details.

Q: Can anyone please answer is the provided 12vhpwr cable compatible with rtx 4080 fe?

It is not, but you can buy corsair compatible cables if you want, pinouts are identical, I was using this with fasgear corsair cable.

Q: Has anyone experienced the issue of the input capacitor overheating or melting?

Suggested contact manufacturer to inquire a defective unit or recall. As a user of the unit I have had no failures or faults in two builds. Caps popping in modern PSUs is usually due to more power being drawn from the unit then it can produce. (Highly unlikely I admit) the fuse should trip first.

Q: Does this have 3 PCI-E power outputs & cables needed for the Asus Strix RTX 3090?

The unit I received didn't work, but it has 4 of said ports, so you should be fine if you want to get it. I think the one they shipped me was damaged in shipment, I ended up returning it and getting something else entirely, non PSU.
