Using a weak power supply with a video card.

[Clumorelo]

Hello guys!

I bought video card GTX 660 which requires 12V and 24A, but I have a PSU which outputs 12V and 18A.
Is it safe to use my current PSU for time while I get a more powerful PSU? I'm not using it for games, only for movies* and browsing for time being.

P.S. This issue hit me when I came to work. I don't wanna burn my GPU.
*Movie quality - DVDRip, if that matters.

On PSU box there is table - 12V1 18A and 12V2 18A; other values I don't remember.

Trash it. That PSU does not deserve to exist. I would not trust it to spin a fan.

Get a good 400W+ PSU from the second link in my sig.

Should be fine if your only doing light stuff on it.. but you'd need a 4 pin molex to pcie 6 pin adapter.

Uh. No. I doubt that thing can put out more than 250W, and would be well out of spec by that time.

True but the op said nothing intense. So even 250 would be fine..

Note where I said that it would be well out of spec by then.

I absolutely agree. You do not want to stress a cheap piece of junk like that unless you like fires in your case and blown parts.

A GTX 660 needs a recommended 430w power supply.

The good news is you can pick up a unit of good to very good quality for around $30-$40 usually.

The Corsair CX 430 is perfect for a low power build like yours and Microcenter has it for $35 after rebate.

At this point I placed on order Corsair CX600; well if you are saying CX430 is okay than it should be fine with CX600

Yes it will be fine.

Thank you guys for quick replies. It's shame I can't pick you all as solutions. )

Glad to help!

I just want to inform anyone who reads this thread that to avoid any risks I took out my GTX 660 and put back GT 220 which I used previously with my PSU.
As soon as I get my new PSU next week I will put my GTX 660 back.

This probably is the safest solution with current PSU.
