PSU good enough?

[joeyo]

Hi, i want to upgrade to a AMD R9 280x or equivalent.

My PSU is a OCZ ZT 750W.

My Current set-up is:-

Intel i7 920 @ 4ghz (over clocked)
6gb Ram
SSD 120gb + 500gb 7200RPM HDD
Razer Blackwidow Ultimate
Razer DeathAdder 3.5g
SteelSeries Siberia v2 Frost

Is my PSU enough to power the GPU with this setup?

i did the asus PSU wattage calculator and it said i would need a 850w. But i thought i would ask here due to the knowledge of others are usually different.

Thanks

Joe

"Good enough?" is a question you should never have to ask about a PSU. For a few dollars more you can buy the best quality and high enough wattage to be beyond this issue. Think of the extra cost as an insurance policy.

Power consumption AMD Radeon R9-280X
1.System in IDLE = 119W
2.System Wattage with GPU in FULL Stress = 350W
3.Difference (GPU load) = 231W
4.Add average IDLE wattage ~10W
5.Subjective obtained GPU power consumption = ~ 241 Watts

So with other components you have a 750W PSU should be sufficient.

•AMD R9 280X - On your average system the card requires you to have a 550 Watt power supply unit.
•AMD R9 280X Crossfire - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

Note : You have a TIER 2 Brand PSU so its good enough to run. Info here :

I realise my wording was wrong for the question in asking. "Powerful enough" maybe instead?
Cheers

Thanks for the reply, very informative. Had a 2 other people say something similar to me about my 750w being sufficient.

Good to know, Thanks

My answer would have been the same. Never too much wattage.
