Larry Ortiz5 said:Well, that power supply should hold up just fine, honestly. A 7750 or even a 7770 aren't exactly huge power hogs. Personally, though, I probably wouldn't opt for that specific unit because, unless I'm just going blind here, I don't see any 80+ rating mentioned anywhere 😁. If it were me, I’d look at this instead:
I suppose I was looking through all those different deals and I completely forgot to check the efficiency ratings... and yeah, I missed the fact that there isn't an 80+ label
. Anyway, I took a look at the one you suggested and it seems decent enough, except for the fact that it shows 36A on the 12V rail? Is it possible the max is actually 20A on the 12V line? Also, if we do the math, 36*12 equals 432, which feels a bit... well, silly
.
I guess I have just one more question: Is it actually better to pick up a power supply that has a single 12V rail versus one with multiple rails (like 12V1, 12V2)?
I think I read somewhere that having more rails might allow for more power delivery, assuming the individual 12V rail is limited to 20A. So, if I end up with a power supply that has two 12V rails, does that mean I get two cables? And would one go to the motherboard while the other just sits there as decoration? 🤷
