Starting a bitcoin minifarm

[Decox]

I got a Spondoolies SP20 for 120$ but seeing as normal PSUs are 200+$ for a decent 1200w one i've been trying to find a server psu all I could find though is this.

Will this be good enough to run my sp20 or should i be looking for something with more power?

i'm new to this whole bitcoin world so any help would be appreciated <3

That configuration should work (the connectors are correct 6-pin PCIe auxiliary power connectors that appear to be properly wired), but it is close to the power supply's limits. Since power consumption goes up with clock speed, I would advise downclocking a bit (it would help with cooling as well). At 1400gh/sec it should only use 800-900 watts or so according to this post.

Would that be a better option or should i invest more to get 2 750w or something and overclock it a bit?

and i just found a 725w psu and if i couple that with my old 500w psu would that work?

No, it would likely not, and I would strongly advise against it for safety reasons. PSUs that are not specifically designed to operate in parallel may cause issues as one sources more current than another due to minute variations in voltage. However, if you downclock even more you may be able to get the consumption under 725w although whether that's reliably doable is not something I'm sure of.
