or...Go to New Egg, order a 750w with 4 pci-e cables that DO NOT need to be Spliced together. Might cost 80-100usd.

Good Luck with your Studies!!!

Your 30$ "600w" PSU will be dead in 2 days. If you're lucky, it won't take the miner with it.

I will hook my multimeter up to it, with a arduino (connected into multimetes circuit) so it can watch and cut the power (with a relay) if it uses too much amps... Don't worry the PSU will survive Smiley

Your $30 "600w" PSU will die in 3-days; when it dies, it will take your miner, multimeter, arduino, grandma, grandpa, and your mom and dad, along with it.

What's your next glib answer?

wait 1 minute

fast answer is maybe.

detailed answer is

if the machine starts up with your psu and you get into the gui go to freq setting drop freq to 300 asap.

300 freq will do   about 970-990 gh at about .52 or .54 watts per gh   this is about 520 to 550 watts

if you psu is using 16ga wires for the  pcie cables  and the cables are separate  not 1 cable with 2x plugs at this setting they will not over heat.

after 2 hours bump to freq 325

wait 2 hours  bump to freq 350

wait 2 hours feel the cables for warmth.

If the psu is using 18 ga cables the 2 pcie  cables are rated for less which means you will not do well running at freq 350

I was thinking about changing the cables to short 1.5 mm^2  that should lower the resistance in the cable so it do not generate that much heat. 1.5 * 6  = 9 mm^2 on each.

or i can short the cables...

Hello miners,

I have ordered a Antminer s5. I also ordered a 600 Watt power supply (it was on sale, 30 bucks), it can give 552W on +12V rail. The antminer uses 590 W at the wall, if we calculate with a 90% efficiency power supply 590 / 100 * 10 = 59 | 590 - 59 = 531W usage if the wattage was measured with an 90% efficiency power supply. 531W < 552W = OK!  so a 600 Watt power supply should be fine (not if you overclock). but my question is, can the Antminer s5 run with two PCI-e pins? (one pin on each board), or do i need to mod the power supply?

I'm studying electronics so i kinda know what i'm doing :=P
