Would my Seasonic 550W Gold be ok with an i7-3770 and GTX 780?

[tracerit]

I built my computer early in January and didn't think much about the power supply. I was used to 350W PSUs the last time I built a computer and thought a 550W Gold was phenomenal lol. I also went budget with my video card and got an R9 270. Unfortunately I bought too weak of components for my use and now I'm upgrading slowly.

My current build is:
i7-3770K (no plans to overclock)
2x8GB DDR3 RAM
R9 270 2GB
Seasonic 550W Gold (http://www.seasonicusa.com/images/G-series/G-series-450-550-650-03-550.jpg)
one 3TB 5400RPM HDD
one Crucial M4 SSD
3 140mm fans


I'm going to get a 1440 27" monitor this week and I don't want to skimp so I'm thinking about getting a 780 GTX. I googled and a lot of the replies say that a +600W PSU is recommended but most of those threads are for people who are getting a new PSU. I already have the 550W that I'd like to keep.

If the 550W doesn't work out for the GTX 780, I may just get a GTX 770 now and in summer pick up another 770, SLI it and get a new 750W PSU then too. My dad plans on building a new system then so i'll give him my old parts. THing is i'm not sure the 770 now would be ok with 1440 gaming, especially BF4 on Ultra (2x AA)

You will be fine with your powersupply, I have the same PSU and the same graphics card, your system will probably draw around 400W under load with that setup dont worry. They recommend a 600w PSU but only to be safe, because a lot of people have lousy PSUs. Go for the 780!!

if its 5 years old or older, i'd replace it. running an old psu at 80% is not a great idea.

if its a couple years old, yeah, sure.

 

[tracerit]

i just bought it from newegg a month ago so it's still new.

i'll only be using this PSU until summer, and then i'll get something higher. thanks!

 

[jacktesterson]

It will be fine

 

[aaksheytalwar]

You are fine. Just don't do insane oc with folding at home and stuff

 

[janii]

yes. i got a 500 noname psu powering my to the max clocked gtx 580 and i5 2500k @ 4.7 ghz

 

[blastingcap]

yes

I have a 750w Cooler Master GXII with 4x6-pin and 4x2-pin. It's made for SLI andXfireing 2 cards, not 3. You could SLI your GTX 780 with that Power Supply and overclock the bejeezus out those GPUs!

Edit: Oh yeah, it only cost me $70 Canadian (about $63 U.S.). I see 1000w+ PS going for over $200! What I'm saying is is that you don't need to spend a fortune for a decent PS. 750w will be enough.

 

[aaksheytalwar]

That is stupid advice. You can't sli 780s with a 550 watts psu.

 

[Torn Mind]

The GTX 780 should have a hard limit of 250 W and the PCIe configuration of a 6-pin and 8-pin means the theoretical maximum it can pull is 300 W. It is just Nvidia covering their ass in case someone wants to run that card on a 600 W Diablotek that can pull only 400 watts and then blowing up their computer with an induced surge.

 

[aaksheytalwar]

A highly oced sb I7 can take nearly 150 watts. A highly oced GPU can take 250-300 watts. Motherboard and peripherals take 50 watts. Then there are hdds, USB devices, fans etc. and then capacitor aging degradation.

No probs mate. You can oc all you want on top of it. Lol.

He doesn't have an overclocked Sandy Bridge CPU. It is Ivy Bridge and run at stock.

Hard drives are peripherals. So are USB devices and the like. He has 100-150 watts of room to spare if he did want to overclock.

His card has a HARD LIMIT to TDP. 250 watts and Nvidia made sure it can't go over it.


Capacitor aging degradation is FUD. It would cause the waveform to be more wavy(more ripple), not cause a decrease in amperage capacity, of which PSUs are "blind" to. Unless ripple goes out of spec, the old cap will not be interfering with the operation of the computer until ripple goes out of spec.

That Seasonic can put out a fair amount more than the listed capacity. He's more than fine with it.
