Running a 5850 on a 400W PSU? POP!

[Matthew N. Wright]

My power supply popped!

EDIT: I changed it out to an 800W PSU and the 5850 runs fine now.

Well it's supposed to get hot. My 850w in my gaming computer (not mining) get's that hot too while gaming so it's normal.

Get a new psu

I'm dumb. The instructions were in another language so I just winged it, skipping over the section about needing a 500W+ power supply as a minimum. ^_^;;;

It's a recommendation for the whole system. A 5850 consumes ~175 watts at full load and about 200 OC'ed.

Even a 6990 doesn't consume 500+ watts. (In fact only 375 at stock)

don't forget, 6990's are dual gpu cards. Running a 6990 with a 500 watt PSU is a terribly bad idea. Unless of course, you plan to just surf the webs with it.

[Jack of Diamonds]

Yes, because the processor, HDD and RAM take some power too.
A 500W psu would be constantly pushed to the max on such a system.

p.s. The motherboard draws 75W for all graphics cards the rest come from 6-8 pin cables

Newegg has a Wattage calculator here. I'm not sure how good it is - haven't used it myself.

[IlbiStarz]

Don't rely on power calculators that much though...if you google computer wattage calculator and put in the same things for all of them, you will get different answers for all of them.

Best thing to do is to use a wattage meter and plug your computer into it. If not, add up the recommended wattage of gpu + cpu and then some for headroom, hdds, fans, etc.

800W presently would be more than enough to run a 6990 and everything else without problems. With lesser GPU's you can even manage to fit 2 or 3 cards with an 800W PSU.

By the way, I don't know where you're seeing $300 for an 800W PSU, but I'd be willing to send you an 800W PSU. I'm able to get them as cheap as $130.

This is Korea. There is an embargo here on computers and parts from overseas as Samsung prefers not to have competition. This means that Samsung products are low quality, normal cost, but anything high quality is obscene. My iPhone was $1,000.


The embargo exists, and it's the reason why DELL and other manufacturers refuse to ship to Korea-- but you can still get away with sending parts. It's one of those barely enforced laws.

samsung makes power supplies?

[Jack of Diamonds]

Seasonic has factories in South Korea and sells PSU's there.

It's considered the best PSU brand among Corsair, Silverstone and Enermax.
You pay a price premium but you get a (for all practical purposes) everlasting PSU with the best possible components, japanese solid capacitors, 99.9% pure oxide-free copper coils, ferrite chokes etc.

Never look only at wattage. A 1200W PSU that costs $70 bucks and is made by some noname is guaranteed to be crappy.

sounds like monster cable

Except for wall installations, monster cable is the way to go always.

Unless your dealing with anything digital.
Monster rips people off by making them think the quality of a digital signal can be effected by the cable.
Its digital, it either works perfectly, or not at all.
The difference in the power supply is that these things actually provide smoother power, abet this will only matter if your over-clocking or something, or want an insanely long life out of it.
