Corsair CX 400W enough juice to run this?

Razor-BladE · 27 Jul 2010 at 04:38

I have a faulty antec earthwatts 500w (my fault) that i need to rma to see if i can get a replacement. If not, will the Corsair CX 400W be powerful enough to run either or these?
Note: i haven't actually built these yet, so some components might be ambiguous.

e8200, p35 mobo (p5q maybe), 1 Dvd rw, 2x1gb 800mhz ram, 8800gt 512mb, 320gb and 500gb hdd

If not that, then the same but with only 1 hdd and a 8600gt (or similar gfx card) instead?

Would i be able to OC the CPU?

And if not either or one of them, one of the cheaper ocz 500w should be fine?

it will easily power that spec, and any overclock.

Wouldn't be so sure about the any overclock part but as long as you're not going to push the CPU and GPU to its limits it will be fine : ).

dont be so silly, that spec will hardly stress half that psu.

Even for a good quality PSU it wont pull out what it says on the box, not without screaming like a little girl and then dying few weeks later.

And OCing heavily CPU and GPU will nearly double this.

I'm not saying it won't cope, but I wouldn't run PSU anywhere higher than 70-80% of its rated wattage for everyday use.

I'd rather have my PSU running nice, cool and silent at no more than 50-60% of it's rated power. But then it's just my opinion : ).

So yeh, as long as he doesn't squeeze the GPU to the max and OC the CPU on heavy volts to 4.4ghz it's gonna be alright.

The 5970 takes under 350W load but you won't run it on a 400W PSU will you ?

you scarily dont have a clue what your talking about.

The CX400w is capable of putting out 450w all day long- http://www.hardwaresecrets.com/article/Corsair-CX400W-Power-Supply-Review/750

overclocking the cpu and gpu will not double the power usage, thats really bad advice right there.

and the OP has a 8800GT not a dual gpu, millions of more transistors per core card. LOL

This overclocking cpu guide from Bit-tech http://www.bit-tech.net/hardware/cpus/2010/03/03/overclocking-intel-core-i3-530/4 shows a E8400 at stock 109w and overclocked to 4.25ghz is 141w thats not double.

Yeh, fine then, let's remove all PSUs over 500W and just stick those in everywhere since they can power up 480GTX all day long without breaking a sweat.

It will also sound like a 727 if you pull more than 200W out of it but I guess that doesn't matter and shouldn't bother anyone : ).

Anyways, the OP got his question answered, yes it will power it up fine so I'll end this pointless argument right here ----> .

Use a PSU calculator (such as this one), before posting anymore in this thread.

What you have posted so far only proves you to be both stubbon and narrow minded.

Alright thanks.
I won't be OCing the GPU, the CPU to about 3.4 most probably. Maybe slightly higher.

Will the 520w HX comfortably be enough for a Q6600 (maybe) to about 3.6 maybe, 5770 1gb, 2 hdds, blu ray drive, 4gb DDR3 ram (maybe; if not DDR2), Xonar DX.

stulid · 27 Jul 2010 at 08:14

The CX400 is perfect.

The 520HX is an older model

MeatLoaf · 27 Jul 2010 at 08:27

CX400 will be fine but if you can get a HX520 i would do as its modular even tho it is an older model

Razor-BladE · 27 Jul 2010 at 10:38

Sorry should have clarified, i already have a Corsair HX 520w but using that for my new build; spec stated just 3 posts above. The CX 400w would be used for another build (building for the sister).
But alright thanks. CX 400w it is then.
