Would my PSU handle this?

post #1 of 33
Thread Starter 
Sig rig of course.

Would it handle adding a 9800GX2 (while keeping the 6950)? I plan to get one for folding and I want to know if my power budget can afford it. I don't mean "only if you don't stress everything at once" or anything like that, I mean would it survive if I ran, say, prime95 and furmark on both cards overnight would I have something left in the morning.

+rep for all who help and thank you

I'm not replying because I want the +Rep you're promising. Besides, we are not allowed to verbally offer/promise it to one another. It kinda just goes without saying. I am just replying because I saw your thread and I felt like trying to help.

Anyway, it's basically a 650W power supply because it has a +12V capacity of 624W which is the same as the HX650 and a few others.

So, I'm thinking that if you want to fold on all that, then I think it's not enough.

Really! I never knew that, I throw that on a lot of my posts simply because too many people forget to +rep and I don't want to be confused with those people.

Yikes! Think it will handle a 460 1gb? That's my next option, it gets about the same PPD.

i think its more than plenty, i ran my CPU and both GPU's on 100% once and my PSU was fine. Ur cards use less power than mine.

I have to go with twocables on this, his claim about the 624w 12v rails is correct.

EDIT: WAIT!!!!

Kingwin got their spec page all wrong! It shows 18+18+18+20 as a total of 52 amps. The real sum of the 12v rails is 74a. Now my question is, which one do I believe? The amperage rating or the wattage rating???

It should be enough to run it but when you get the chance, upgrade to a better quality psu such as an antec, corsair, or silverstone.

The 6xxx cards don't get very good PPD from what I hear. Plus the fan is noisy as hell with the unlock + overclocks on it. Please check out my edit on the last post, the amperage is more than I originally thought.

You should be fine, but if you can afford a new psu, it's always good to have a little headroom

It can't be added up that way. 74A is 888W. 52A is 624W. Always multiply the +12V wattage capacity by 12.


Anyway, so are you saying that if you were to get the 9800 GX2 that you would just leave the 6950 idling? I mean if so, then hey - I bet you'd have plenty of power.
