AMD suggests a 750 watt power supply. The only reason I can conclude for this is most people know nothing about computers and buy junk power supplies, and AMD is taking no chances.

Regarding your rig, I do not know how old your power supply is. As PSUs age the become weaker, especially in areas other than where "clean" or on-voltage [120v], no spikes, brown outs, and so on take place. If you live near a huge power demanding business or in many rural areas PSUs take a beating [this is where a good UPS comes in handy]. If you live in optimal power conditions and the PSU is a very good one that is not too old you should be able to run your PSU.

Other important information :

Along with "dirty" voltage at the wall, and the more power required by your computer, the faster your PSU will degrade.

With that out of the way, the Corsair should put out a continuous 500 watts [most Corsairs do], however, try to determine it's quality. You might go to http://www.plugloadsolutions.com/80PlusPowerSuppliesDet... and look up your power supply. If it is not on the list at that site try a general search [review] for your PSU.

Without knowing any good information from you, I do not know how to answer your question.

I cannot honestly answer your question. I can only guess.

I have a Corsair TX650M power supply and am questioning whether to purchase a 750 watt, although I believe I will be OK because I know what my power draw is from the wall using a Radeon HD 6950. At least one of Corsair's 750 watt PSUs is just over $100 at Newegg

I believe on this web site you can hover your mouse on my avatar and my specs will pop up [I am not sure because I frequent so many technical sites, and cannot remember where I put info on all of them, sorry].

However, I do have an Intel Ivy Bridge CPU overclocked at 4.0 GHz in hot months and am safe at 4.6GHz in cold weather. So, my CPU is overclocked and I feel my current PSU is enough for the R9 280X according to current power use. The PSU is just under 1.5 years old.

Make sure you have enough power cables for the video card.

As far as age, it's just about 9 months old. I live in central Indiana, so nothing power hungry here. There hasn't been a brown out in about 4 years either, so I'm assuming it's in decent shape. And I have 2 6+2 pci cables on it.

Not sure about the CPU but at least Gigabyte's R9 280X requires 600W PSU

The XFX one, which I'd be getting, asks at least 500w.

On my psu, it says: +12v 38a 436w -12v 0.8a 9.6w +5Vsb 3a 15w
I don't really understand that at all, but I assume my 12volt rail can supply 38 amps. Now would that be enough?

It wont be enough... I blew a OCZ ModXStream 600W PSU with my 7970(280X but heavily OCed). http://www.tomshardware.com/answers/id-1837310/locked-u...


I'll upgrade my psu. After much thought, I decided it was worth it, considering if I stayed with the 500w, it would burn out faster, so I'd have to upgrade anyways. The one I'm looking at is a Corsair TX750m, it provides 60a on the 12v rail, which should be plenty. But, any other recommendations would be nice. Preferably under $90.

I am sorry about getting back to you so late.

If you have not already purchased it, the Corsair TX750M is a good unit. I have the Corsair TX650M in my computer, however, I have an Intel i5 3570K rarely overclocked past 4.2GHz [because I do not need to, it provides plenty of power at 4GHz or 4.2GHz]. My Video Card is a Sapphire R9 290 and I overclock it 10% beyond reference, and, I actually do not need to overclock it.

I use MSI Afterburner to adjust fan speed to allow the reference cooler to keep the GPU temp no more than 80 degrees C [it usually maxes out at 65 degrees C with a room temp at 72 degrees Fahrenheit [ 22.2 degrees Celsius ].

That was more than you asked for, however, because your hardware is different than mine I felt it would help. Running World of Tanks [game] with almost every game setting at maximum, maximum Watts was 265 for the entire computer [CPU at 4.2GHz, Video card at 10% overclock].

Some games may require more watts, however wattage, this will give you some idea of at least an average modern game. Note that although a cheap [junk] power supply may be rated at 750 watts it may only be good for 300 Watts, and if those Watts are peak power [not constant power], that computer would be near maximum capacity and damaging to the following:

For example, expect that type of junk power supply to die an early death or cause damage to other components, and/or cause other odd problems, such as games or programs crashing, and Microsoft Windows BSOD [blue screen of death] because of poor PSU components.

Most people know nothing about power supplies and purchase the least expensive thing they can find, in this case probably $35 U.S. I am glad to hear you are looking for quality and are asking questions.

I picked up a Rosewill Hive 750 modular on Newegg for 38 bucks. for the price, it's a hell of a PSU.
