My new gamma is happily toiling away at around 1.2 to 1.5 TH/s, but I've seen others get way more out of it.. like this pic I found online of a gamma getting almost 2 TH/s. Could I possibly achieve something like this if I had a better psu? Anyone tried this and/or have psu recommends for gamma?
Have you upgraded the fan, heatsink, etc on your bitaxe? Otherwise you will fry it with a larger psu lol.
@sunny-skies123 Yup it already came with a fairly robust heatsink and upgraded fan (noctua). It's running steady at 54c with 20 degree ambient and fan at 90%, so not shabby at all. Guess I'm just a lil greedy for hash and want to see how far I can push it haha. 🙃
I recommend a meanwell power supply. The one I use is https://www.amazon.com/Mean-LRS-350-5-Power-Supply-Signs/dp/B07PDTDKRY?ref_=ast_sto_dp&th=1
@tech-guru2025 Nice! Looks like it has plugs for 3 units but enough power for more? Could I, theoretically, connect more units if I splice? 🤔
@magicmike42 Hmm, I'd say yes but remember the power rating shown is always "peak" so you never wanna reach that. Rule of thumb is don't exceed 80% of capacity so... this one is 300w and the gammas consume 25 to 30w each.. I wouldn't stack more than 7 just to be abundantly safe. You technically could get away with 8, but not worth even the small risk IMHO.
@magicmike42 typically a meanwell 5v 300w on Amazon will be enough to run several bitaxes at once.
There's not a hard and fast rule on how many you can connect because each ASIC is unique and it also depends on how hard you overclock them. Monitor the actual power consumption of each unit and then determine from that how many units you can safely connect to a single power supply.
