R9 280X PSU Requirement

[TheKerangMan]

The new Sapphire R9 280X required 750W as stated thru their specs..but someone said true power Seasonic 620W will be good enough for the GPU..well which one is efficient and real answer..? please help me,i'm confused..Thanks in advance..

The 750w requirement would be for two cards in CrossFire. I am completely sure that the Seasonic 620w is plenty for a single 280x, no worries at all.

I know this is an old thread, and that the card might not in actuality need what's recommended, but the Sapphire website DOES indicate that for a single R9280x, a 750w PSU is required. It lists a 1000w for crossfire, as seen below.


PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard.
◾2X75 Watt 6-pin PCI Express power connector is required for CrossFireX™ system.
◾1X75 Watt 6-pin PCI Express power connector is required.
◾4096MBMinimum of system memory.
◾Installation software requires CD-ROM drive.
◾DVD playback requires DVD drive.
◾Blu-ray™ / HD DVD playback requires Blu-ray / HD DVD drive.
◾750 Watt Power Supply is required.
◾1000WattPower Supply is recommended for CrossFireX™ System.
◾1X150 Watt 8-pin PCI Express power connector is required.
◾2X150 Watt 8-pin PCI Express power connector is required for CrossFireX™ system.

But as previously mentioned, that's probably just Sapphire playing it way to the safe side.

hey guy.. i also running 750watt thermaltake toughpower 80 gold with 5 year warranty. 2 month 12 hour gaming no problem so far. (msi gd 65 .4670k. msi R9 280x 3gb . 8gb kingston hyper 1866hz ram)with 9 fan install (cm scouts 2).

This is insane. As I made my new gaming rig, I was aiming for power efficiency. From a low TDP Haswell i7 CPU to the new Maxwell GPU, my whole system is at no more than 150-175W under heavy gaming. You guys need 1000W power supplies?? Hope you are getting 4-5 times the gaming experince I am, because you're sure paying for it on your electric bill.

Hi, I have a Evga 500w 80 plus psu and I was wondering if my power supply could run a fx6300 running stock speeds, and a Sapphire r9 280 3gb 384-bit running overclocked. I also have a Asus m5a97 le 2.0 and a cd drive, hdd and 4 case fans. Any help would be much appreciated, this build has taken forever (almost a year) because of DOA parts and shipping delays, thanks again!

wtf is this guy talking about larkspar? and he's an expert in this?
Manufacturers are wrong?
Is he going to reimburse anyone if they burnt their cards from using lower psu than manuf recommended psu?
Just a common sense, go with what manufacturer recommends.
Just be honest. you're asking this question because you don't want to spend few extra $s to buy a new psu.

Those charts mean when you run gpu but your psu doesn't only supply power to your gpu but all sorts of other things like.... hmmm cpu? and all sorts of other crap. And you know we love to overclock our shit which will even require more power.

You ever had your power go out in your house because you were using too many elec. stuff at the same time? like say microwave, heater, a/c, hair dryer etc?
Well shit, if you only used those items individually, you wouldn't get a blackout.
Does the chart include or even mention about other components in conjunction? that would be impossible cuz there are thousands of different variations w/ different power requirements.

Just even think about crazy random spikes which will require fans to go crazy which will require more power consumption.

Just be safe and go w/ manufacturer's recommendation.

I'm sick of this thread still popping up. Card vendors (like Sapphire) often grossly overstate their PSU requirements because there are a lot of cheap, crap PSUs that are sold as high-watt units. The PSU that the OP asked about is not cheap and crappy - it's a high quality unit.

@c2s: I stand by what I said: "I am completely sure that the Seasonic 620w is plenty for a single 280x, no worries at all. " A quality PSU doesn't suffer from as you say, "crazy random spikes"...

A Seasonic 620w PSU (the M12ii or S12ii models come to mind) is perfectly sufficient to run any R9 280x on a typical system. That is true for the R9 280x Toxic edition or any other R9 280x.

This thread has been answered for well over a year and should be closed. If you have a question regarding a power supply OTHER THAN A 620w Seasonic and/or with a card OTHER THAN A R9 280x then CREATE A NEW THREAD.

will sapphire vapor X r9 280X run efficiently with a seasonic 620 watts psu or any other antec 650 watt psu

but the specs said 1000W needed for crossfire..i'm confused..

Companies must cover themselves is all. They conclude that number assuming you have the highest end most power hungry components going into your gaming rig. They cant say 300W will be fine and then someone go buy 300W psu to run their whole setup.

just to meniton that one friend has 2 crossfired r9 280x's and fx 8350 with Fortron silvler PSU and he says that it's running fine
