So I'm thinking I will need something in the 1500w area. I was just wondering if anyone had any first hand experience with units of that sort of power and if so, which would you recommend? Cheers
Don't know if i want to make another PSU comment on R9 290s but In the Quadfire review I posted in the 290 thread the guy states his system pulled more than 1.3Kw from the wall The Zalman is a smidge over 90% efficient full load so that's over 1.18kW gaming, if you did some mining on it and didn't clock it down for efficiency because your hardcore or if you went for some beefy overclocks I reckon it'd do more Of course he had 290x which do use a bit more power so you might scrape by with what you have, get a power meter on what you have and judge for your self, everyones hardware setup is different.
I'm looking at moving the whole rig into a Corsair 900D, so I could go dual PSU. However, adding a second PSU seems to have a large impact on the space for radiators in that case.
Evga super nova nex 1500 costs aprox £330 Enermax 1500 egt £290 ish. Used both in builds recently. Mining rig for a m8 with 4 r290x the psu just powers the cards that psu alone is drawing 1300 watt from wall in litecoin. ( enermax) Done another for a friend with 3 780tis that psu is overkill but seems stable enough. ( supernova with this build.
I got my power meter today. When mining, the rig is pulling 1600w from the wall. During gaming and benchmarking it hovers between 1200w - 1400w so I may just use dual PSUs.
Blimey, that is a lot more than I would of expected, you've not included monitors etc in there have you?
I've used my Silverstone Strider 1500W for about three years now and it's still going strong. No idea what I pull from the socket though. Are we going to see some benchmark results for all those 290s ?
Yes it is a lot. Nope, the monitor is plugged into a different socket. It pulls about 100w. All that was plugged into the meter were my two PSUs.
Yes, I will bang up some benchmarks soon. I ran a loop on 3DMark11 earlier with the extreme setting. and scored just under X13000. I'm not so familiar with 3DMark scores though, so don't know if this is good or bad.
You'll have the combined losses from 2 psus of between 20-30%, a good single unit would save some load.
