Will I need to upgrade my PSU for Nehalem?

[Dent0n]

Hi, I would like to know if my 485W Enermax Noisetaker (original, not II) will work with Nehalem/Nehalem mobos. It's an ATX2.0 PSU, few years old now.

If not can you recommend me one currently on the market that would also support the new 4870 graphics card from ATi? I run 3 HDDs, 4 sticks of ram and a C2D e6420 on a P5N-E SLI mobo. The CPU is OC'd @ 3.0GHz, working on 3.4 (looks doable).

Sorry if I'm asking a question that can't be answered yet, but speculation is also welcome.

Welll, if Intel decides Nehalem boards need different voltages, or a different plug, then maybe. How many amps on the +12v of your Enermax?

i would upgrade it

I'm quoting someone else with the same PSU, but:

"dual 18A rails with a total of 32A"

Also I heard aging PSUs can screw up an otherwise possible overclock, is that true? If I could get my 3.4GHz by simply upgrading the PSU I would do it in a heartbeat.

Thanks for the replies!

dual 18A does not mean 32A they are not additive

my main concern would be that it does not have the 8pin eps12v which is alright if you arent overclocking, but nehalem will increase the power requirements over c2

LOL... you're not very "additive" yourself. Try adding 18+18 again...

Do you know anything about PSU's to make that claim? Most people on these forums know that two 18A rails will not produce 32A of power, because you cannot simply add the amperage across rails.

GTFO

And hopefully most people on these forums know that 18 + 18 = 36....

Never Assume anything here...

You will want an ATX 2.2 EPS 2.92 Compliant PSU if you want to cover the bases.
PSU's, hard drives, and cases are Infrastructural.. you can never go wrong spending money there.

Well, let's see... math is out. Reading comprehension is out. What's left?

Knowing the cheapest nehalem CPU will cost $300+ for quite a while, I wouldn't let my 2 year old PSU run it. Not when it's an enermax, they tend to go out with a BANG I'd spend 50-60$ on at least a halfdecent NEW psu.
