Is my PSU sufficient?

[Bliznipa]

Hi, I currently have in my gaming rig:

Intel Xeon e3-1231 v3

16 gb ram

Msi z97s sli krait edition mobo

About 13 led case fans

650w corsair psu

R9 380x power color gpu

Optical drive etc

 

I have a new powercolor r9 390 8gb that I plan to add for mining. I'm considering upgrading to the corsair all white modular rm850 psu (if I need to).

 

I guess I'm just looking for advice on sizing my psu. I'm thinking I might later add one more r9 390 8gb power color for mining if they ever come available. Assuming I do add one more, what size psu would you recommend knowing the system would most likely be running 24/7?

 

Thanks in advance

r9 380x uses up to 200w

r8 390 uses up to 250w

when mining, they're not going to stay at that peak power consumption.

 

if you're going to just mine with the system you listed, the 650w will be enough. 

 

unless 13 is a typo ... wtf do you need 13 fans for?  Anyway.. fans use 2-3w each, the memory uses maybe 5w , that cpu uses maybe 60-100w ... the 650w should be good enough.

Why do you need 13 fans dude...?

 

Anyways, yes 650W should be enough. However, what 650W is it? Is it a good 650W Corsair PSU like a TXM or RMi or is it a cheap one like a VS650?

Interesting story. 13 isn't a typo lol. 13 LEDs is for pure badassery in my all-white case setup. I have a cx600m corsair currently. Considering the Rm850x because its white, but I'm wondering if that will be enough for my setup including a r9 380x, and 2 r390s for mining, or is that just too small? I may add more late for mining, so I'm considering the 850w PSU and adding another 850w PSU later, but in the meantime I'm not sure if 850w is sufficient for those 3 GPUs.

 

Thanks

You know if you sleep in the same room as your PC having all those LEDs is not a good idea just a heads up. Also, do you pay your own electricity bill? Mining on a 390 is not a good idea. You'll lose more than you'll make easily.

ty that's good to know. Its a brand new 390 that I haven't opened. Just looked at TDP comparisons and that's really high. I might not open it at all and resell it. Any suggestions on more efficient mining GPUs? are rx 480 8gb or 580 8 gb more efficient? Assuming they sell at regular standard MSRP, not what they are now, which would make more sense to use in the future?

My RX470 used to do up to around 23 MH in ethereum, before the complexity increase and coin value drop. Now it's maybe 17-19 MH , i stopped before the drop in value so cant be sure.

Anyway that's for everything stock no custom bioses, maybe around 100w power used by card.

 

Vegas are rumored to do 70-100MH so if that's the case perf. per watt woud be great, ike replace 3-4 rx 470 with single vega that uses as much as 2-3 cards to do it.
