I'm going to get a graphics card upgrade soon and I was thinking of getting the Gigabyte R9 280x which says that you need a 750w psu to run it but I only have a 500w 80+ Bronze Corsair CX 500w one :(
Will I be able to use it? I'm using an i5 4670k if that's any help.

Thanks, Jake :D:D:D
 
Depends on the rest of the system. The card itself has been shown to draw anything up to around 250w, so for a standard single card system with a normal amount of drives, 500w ought to be fine.

There's a 240gb Kingston SSD and a 1tb WD Blue drive for storage, 5 case fans, 8gb crucial ram, hyper 212 evo heatsink with 1 fan and that's all that I can think of that would affect the amount of power used
 
The CX500 isn't really a 500w psu though. Just because a psu says 500w on the label doesn't mean it can deliver that on the 12v rail where it's needed most. Depending on which version of the CX500 you have it could have as little as 408w on the 12v rails or 456w on the newest version.

I only got it a couple of months ago because I needed to replace my old one and it was cheap but the odds are it's the latest version
 
I had a corsair 550watt psu when I bought my 7950.

I had my cpu (fx6300) clocked @ 4.6
2 500GB WDG HDD's
ASUS ATX Board
8 case fans
2 led strips.
closed loop system
and of corse the 7950.

when the gpu got upto full load, sometimes my system would crash out.

I upgraded to a tx850 (from the mm) and now it works fine.

I don't know if your cpu is clocked or not, or if you planning clocking anything.
if you do, you will defo need to upgrade.
 
I have an 8320 oc to 4.2, gtx 780 SC, 1 ssd, 1hdd, 6 fans, a h80i, monitor, 3 peripherals and my CX600m is not up to the task.

Had to step my oc's back until my new psu arrives.

An 8320 uses a lot more power than a 4670k though, especially when overclocked

I did a quick calculation. Came back with a recommended wattage of 448w. So 500w ought to be fine, although this needs verifying as total wattage is only a part of the equation. 12v rail power is probably most important so check your unit (on the side) for the 12v power available. Any extra load will likely require a new power supply though.

True, that gives a fairly accurate view but it's never 100%, I'll get the 600w one because it's ultra cheap for me and it's new (from a friend) and that should be fine, thanks everyone :P
