Could my PSU support a 3.0E or 2.8E at 240fsb?

Hey there, I am really interested in OCing a 2.8E or a 3.0E - but I don't know if my Antec True430 can keep up with it.

It is said to have a 20amp 12v rail online, but the actual PSU shows a 26amp 12v rail. (on the sticker on the side of the PSU)

Either way, do you think my PSU can support a 3.0E to around 240-250fsb? or should I opt for a 2.8E (assuming the 2.8E uses less power than the 3.0E?)

I will be using a zalman7000alcu, I modded my case so it has a blowhole and side window fan (along with the stock intake/exhaust) - I don't think cooling will be too much of an issue (it is also about 50F in this room right now)

My ram overclocks like crazy, so I was hoping to get a nice FSB out of this chip, so I ask you, which chip will I have better luck with assuming I am going to keep my Antec True430?

Having a 2.8E and the same PS, Antec TruePower 430 and I have got my FSB up to around 244, so yours should be able to handle it.

Good luck

Thanks for the response RangerXLT8, do you know if the 3.0E draws significantly more power than the 2.8E?

The 2.8E and 3.0E suck about the same amount of power. Your PSU should handle it ok as long as you don't crank up the vcore too much. Try to get a D0 stepping regardless of which one you choose.

Killaapp, I also have the 430 True power and can push my 2.8E to over 250 FSB with no problems

The 3.0 and the 2.8e are the same with the thermal guide line so I would have to say that the power draw is also close

That's why I have the blue stars...

Wow, thanks guys I really apprecaite all the input. I think I am going to look into the 3.0E. Is the SL7KB the only D0 stepping?

Thanks a ton.

The SL7E4 is also a D0 stepping... I had one of those a while back. You can probably find my old post if you search.

Id never even noticed them!

I can never take my eyes off your avatar

surre your chip should run fine...I'm running a 3.2E on an Allied 400p/s smoked 2 500 w p/s in three weeks
