500w Seasonic enough for 7950 OC'ed?

Hello.

I have a meaty, heavy Seasonic M12 500w. My system is: 2500k OC'ed to 4Ghz, 460SE, 6gb RAM, 1 SSD and 1 HDD, 2 120mm and 2 160mm fan. and a soundcard.

I plan on upgrading to a 7950, and plan on overclocking it. Most reviews would put whole system draw at around 400w when using a 7950, but I have a good bit of hardware so I might be pushing it.

Should I just stick with a friendlier 7870?

I ran my system in my sig with a 7970 for a while off my OCZ ZT 550w without issue. (45a on 12v)

I'm using quite a bit of voltage on my O/C too 24/7 (1.4v). Been running for near 2 yrs here fine.
 
I run an i7 3770k and a powercolor hd7990 on a 660w seasonic with a slight underclock. you should have no worries. since a hd7990 uses more than double that of a hd7950

Yeah, it'll be more than enough. A whole system won't consume 400W with a max OC 7950 unless you're also heavily OCing a power hog like a 3930K or a 990/990X. Your CPU OCed should still consume very little.

Looks like he's cutting it too close. aaksheytalwar, you're gonna need to upgrade to a 2000W unit soon or you risk blowing up your system.

lmao :biggrin::awe:

Well I can run my system with a 400 watt power supply so a 500 watt power supply can run a 7950 without any issues.
 
Im buying a third-hand 7970 XFX Core Edition for the same price as a 7950 new. Will be the first time I have a super high end card after years of picking the mid-range of the last gen.

If my 500w Seasonic M12 cant hack it I can try and underclock/undervolt it.
