So my friend just bought a new graphics today which is a Zotac Geforce 450 and we forgot to look at his power supply if it was strong enough. So his PSU is 400w and on the video card`s box it says 400w minimum.

So my question is, would it be safe to use at this point or wait to get another PSU?

Computer specs if it helps :
PSU 400w (generic brand i think)
3gb DDR2 RAM ( i don`t know the brand)
Intel Core2Quad Q6600 Quad Core

If you can post the brand name and model number of the PSU we would now for sure but if it has 24amps available on the +12volt rail it is sufficient.

Here is a link to some what of a chart that will show you where or if it even made the chart. My PSU is crap and It did not make it on the list. This might help a little but rolli59 knows what he is talking about so listen to him and Good luck

The brand name is Delta Electronics Inc. and as for the model number it`s DPS-400RB A.

I`m not sure about the 24 amps part but theres some info that could help here :

Input: 100-120v, 200-240v
Output: +12v/16A (Max)
Max power: +5v/14A (Max)
400W: +3.3v/20A (Max)

The amps it outputs is 16, so no it is not wise to use this power supply with the card. I didn't check, but if that guy who said you need 24 amps is right about the amount, then you need to buy a new power supply.

That PSU isn't going to be able to support that system, delta makes good units but it simply lacks the 12 V capacity to support the system. The GTS 450 needs 8.8 A from the 12 V rail itself, the Q6600 needs about 9 A more which already puts you over the limit.


Get a new PSU, a good modern 450 W would be more than sufficient, that unit is old and was not built for systems with high power GPUs and high 12 V loads.

Alright, well thanks a bunch for the answers guys. So i had another question though.

What would you guys recommend me? Thinking about 550W-600W so that he wouldnt need another one for a while.

Like what brands would be the best and what should we look for other than the actual wattage? (i have a Antec psu in my own computer, i heard they make good psus)

From the good brands they are pretty much all modern with a high amperage on the +12 volt rail. If you have a budget then we can help but the link that DM186 posted is a useful tool! Here it is again http://www.eggxpert.com/forums/thread/323050.aspx

You have to look at the label more closely, it has dual 12v rails and a combined 12v output of 30 amps, it's fine
