FAQ: Recommended Power Supplies - Page 366

post #3651 of 6753
Oh, sorry, the Opterons. I should've checked the motherboard part numbers and figured from that. (I was doubly confused by the wattage ranges and assumed that had to mean GPUs, though 4p of course means processors.)

As for converting to USD, that just creates problems as some careless readers (me sometimes) will think of US prices and get confused. The price when converted doesn't give any extra info that the price in NOK doesn't also provide, and it's potentially misleading. Also, doing the conversion means that somebody will have to convert back in order to compare to prices of products actually available. I guess it's not as much an issue if you're only looking at those three power supplies, but likely a better pick is something else altogether anyway.

Anyway, the wattage is way more than you need. The current revision of XFX Pro/Black 850W uses Seasonic KM3 (which is borderline platinum on the gold-rated models) and has two EPS12V connectors. Those should be plenty, and they're cheaper than you were looking at before and definitely better than the Silent Pro Hybrid and newer than the Black Edition 1250W.

edit: if you really get mild OCs on the 8439s and want even more capacity for those or even the 6174s, Cooler Master V1000 is mostly the same thing with a better fan and higher capacity.

Don't worry, I should have been more specific rolleyes.gif

Snap, didn't know there were two versions of the XFX black series, it was a XFX Pro/Black 1250w I meant, sorry for the confusion...

Anyways, since this will be running full load 100% 24/7, efficiency is really important, don't want a heart-attack when I get my powerbills... biggrin.gif

But I checked the power req over at eXtreme Outervision's PSU calc, and it recommends 955W on the 8439's, and 800W on the 6174's, before any OC, and especially the the 6174's get really powerhungry under OC'ing rolleyes.gif

Yeah, well you still have to factor in efficiency and you also have to know that this thing isn't absolutely 100% accurate. I don't remember what the explanation is though.

AAnnnd don't forget you first have to have the rig running before you can use this, which requires a PSU, which I'm trying to find the best alternative for tongue.gif
However, I think I will skip the OC'ing for now, as it is quite the ordeal apparently, so that's off the table.
Any suggestions for a PSU?

Take some Melatonin at bedtime for about a week to kind of reprogram yourself. ;)

H8QGI+-F mobo with 4x6174

6174 = 115w TDP x 4 = 460w. + 100w overhead for "other" stuff like RAM/mobo etc... since this is a server rig, you have to add up all the fans individually cuz server fans use a good amount of juice.

MBD-H8QM3-2+ mobo with 4x8439

8439 = 137w TDP x 4 = 548w + 100w overhead for "other" stuff etc... same applies to fans you are using

so... essentially you need a 600w PSU for the smaller rig and a 700w PSU for the bigger rig. power of the fans can be shared between the PSU's depending on how you have them set up (assuming open bench style? )
