If a gpu's recommended wattage is about 120w higher than the computer's power supply, is there a way to get it to run at a lower capacity?
I told my dad I was gonna try and upgrade my computer this christmas and he apparently just has a titan GPU lying around. My power supply's first number says it does 480W, and apparently the titan needs 600.
I don't exactly want to turn away something as big as that, but I'm not sure how easy it would be to replace a power supply either.
also, newfag question: I saw higher watt numbers below 480 when I opened the case up yesterday, are those significant at all?

buy a new PSU. Its easy as shit to install

Oh okay.
Another question though. Should I pay attention to the unchecked rows on this? I'm not sure why they were included.

what the fuck
>>51868125
those show you the different amperage based on how many watts it takes to power your shit
>>51868156
Would I actually be able to get to 680 on this PSU, then? It's probably still too low, but considerably less so.
Just buy a 750w evga (good brand) psu dude, don't risk damaging things, a good quality gpu deserves a good quality psu

No

EVGA doesn't make any PSUs. They rebrand both good and terrible ones.
Generally you're good if you buy anything Super Flower, high range Seasonic, or high range Corsair made.
My personal suggestion is the RM1000x.

It means that the PSU comes in different models. You have the 480w model.

Dude. Do NOT use that power supply with ANY GPU. What you are looking at is basically a 190w PSU.
GET A NEW PSU

>high as fuck 3v and 5v rails
>low as fuck 12v rails
Thats a piece of shit OP - nearly everything these days is 12v based and good units will provide their rated wattage on the 12v rail alone.
A titan would kill that psu through the amperage alone.

Use this as a starting point for research for getting a new psu.

Dude. The manufacturer was too cheap to print three different stickers for the three models of power supply it offers. This bodes poorly for your attempt to push it's limits.
16A on a single 12V rail is nothing. I would be hesitant to run a 960 on this let alone a Titan.

Good place for psu reviews yo.

To expand from here:
GPUs don't pull power from the +3.3V rail. They only take +12V.
The Titan has specs saying you need ~at least~ 38A of power on +12V. You WILL fry your system if you plug that power supply into a Titan.
Get at the very least a PSU that has 38A on +12v
>>51867795
This is what an 850w PSU looks like (EVGA 850 P2)
Notice how the wattage is combined by the +12v itself, and not the entire combined wattage.
Your PSU on the other hand is barely 200W on +12v.
Honestly I doubt that psu even has enough pcie connectors to even plug a titan in (thank god).

Damn that is a fine unit to do that. I forget if its EVGA that are rebranded SuperFlowers or not.
>>51869072
Some (not all) are Super Flower.
I got it free from work (I work for them.)
>>51868145
That's a terrible PSU.
>16A on 12v rail
Just get a new PSU and don't go for shit brands like arctic, diablotek etc.
>>51869088
Well thats just snazzy. I personally use a superflower 750w leadex gold because I run an all AMD system and as such will kill lesser psus when I slam my system.

This pic triggers /g/ because 1) anon think its from reddit (its not - the data is from tomshardware and 2) /g/ is about 3 years out of touch for psus.
>>51869026
Yes, the PSU is rated for 850W max COMBINED. That the 12V alone is able to output that much does not change how the wattage class of a PSU is defined.
>>51869185
Good PSUs are overprovisioned. Bad PSU are rated for peak.
