Am I a Mad Man or Could This Work?

Khajiit Dealer

Long story short, I want to power my second 980 Ti separately with a 450W PSU alongside the current 750W one I have now.

For SLI, could I do this without any problems?

Will it work? yes

 

Should you just go and get a new power supply instead? yes

Would it work? Yes.

 

Frankenstein of PC's? Yes

 

Could Linus use this for a video? Yes

It looks as if the peasants have risen up, and found swords!


But their sword's look a little short, if you know what I mean!


Good! The squires need training anyway!

You can actually run two 980ti's on 750w if it's good. Unless you have extreme cpu too.

My 750W is a CX so that's a no.

I'm too lazy to redo all my wiring

then just get another psu. Two psu's is never a good solution.

And you won't be lazy jump starting that psu every time you want to power on your pc?

My computer already looks like shit, I value performance over looks.

I'm worried about fucking up everything when I take out the PSU and replace all the cables.

Just make sure to plug everything in the right place. Most of the connectors only fit into one place. Also you can look on youtube for tutorials on how to replace a PSU.

Depend on the power supply. If the 450w is a XFX TS Bronze 450w, for example, I wouldn't advise it as it wasn't design to handle such a load (high 12v load from the PEG cables, with no loads on the 3.3v/5v). If it is something like the Cooler Master GM, Fractal Design Edison M / Integra M, XFX TS Gold, the upcoming Corsair CX450 (or "Vengeance" for Germany), etc., they would handle those loads better. Once you get that, you would need to either make an adapter or buy one that have that PSU turned with the other.

It's not hard to. Just unplug the old PSU and put the new one in. The cables only go in one way.

Upcoming CX450? Do you have any sources?

I'd mentioned about it a few months ago that Corsair was planning on updating their CX line to have DC-DC. Well, here's a source from a 3rd party that had talked to Corsair about it sometime at the end of Oct. He got some factory documents on it as well. http://www.jonnyguru.com/forums/showthread.php?t=12723
