Will my PSU handle the R9 280x?

[statsboy]

So I currently have:

Crucial Ballistix S XT 8GB 1866Mhz DDR3 Gaming Memory
OCZ Vector 150 120GB 2.5' SSD
Intel Core i7-4790K Processor 4.00 Ghz 8MB Cache - Socket 1150
Gigabyte Z97-D3H ATX Motherboard - Socket 1150
WD Caviar Green - 1TB SATA 3 Gb/s 64 MB Cache

And a 500W 80plus bronze PSU

So will adding: Gigabyte AMD Radeon R9 280X Graphics Card - 3072Mb GDDR5 be too much for my PSU?

I do game every so often, nothing too major (CSGO, Dota 2) but upgrading for Witcher 3 so eventually it will have to perform on high settings

You need a good quality 600+W power supply to handle the r9 280x. eg Seasonic 620, XFXC650 or Antec HCG 620M

A good quality 500W psu can handle that card but seeing as it is bronze and you didn't tell us the brand (it matters due to the quality of whats inside) I would advise against it.

A good choice for a somewhat future proof psu would bee an EVGA supernova 750w G2 that is fairly cheap.

It might do, a decent quality 500W PSU is fine for a 280X (I run an FX8320 cpu + an R9 280 off a Corsair CX500 psu).

The main problem though is not *all* 500W PSU's are the same. If you have the make and model I could tell you more. If you want to check yourself, have a look on the side (there is usually a sticker stating the maximum currents the supply gives).

My PSU has a single +12V rail which is the best bet for running a high performance graphics card on a mid range supply (the CX500 provides up to 34A on the +12v rail). What a lot of the cheaper supplies do is offer 'split rails' instead (e.g. it might list it as +12V1 20A, +12V2 20A or something like that). The problem is you can't really feed 2 rails into one card, so a supply like that would be limited to effectively 20A for a single card which probably isn't enough for the 280x.

RealHardTech recommends 600W

RealHardTech recommends 600W

They have to take into account the margin of error that comes with the different makes and models. I ran 8350 and 280x of a 550W Gold psu. With a Corsair 650 I OCed both and they ran stable 4.7Ghz on the processor and about 8% oc on the gpu, and as you know that ate some power cause AMD

I agree, though I think those recommendations are based on the fact that so many 'high power' supplies are actually totally useless.

I guess if you spec high enough even a cheap OEM supply might just about do it, though I personally wouldn't recommend it. The number of computers I've repaired because people have purchased an 'OEM' 850w psu for £20 and are then surprised when it either doesn't work, or dies quite quickly running with a decent graphics card.
