500W PSU with EVGA GTX 1080 FTW

[TheGeekOnABudget]

Well I just bought myself a evga ftw 1080 and I have a 500w 80 plus white evga power supply.

Well that power supply only has a 1x8, 1x6 pin cables but the house has 2x8 pins.

I know the minimum power supply for the 1080 FE is 500w.

Now since the FTW is factory OC it will probably require more power but I don't plan on maxing out this GPU for at least 6-8 months and by than I will have a 600-700w psu.

I'm going to be running at 1360*768 most of the time but will upgrade to 4K in 6 months.

Should I get a new psu or will this be able to power it for the time being.

System specs-

Cpu- i5 2500K @4.5

Motherboard- Asus P8Z68 gen 3

Cpu cooler- Hyper 212 evo

GPU- EVGA Gtx 1080 FTW

4 system fans.

2Tb HDD

1Tb HDD

500W EVGA 80 Plus white.

Thanks for the help.

P.S. I only upgraded to the Gtx 1080 because I sold my RX 470.

Should be able to handle it. I think wattage estimates are always worst case scenario.

Try to get your hands on a cheap EVGA 550 G2, I wouldn't trust the power supply you have right now with a 1080 with dual 8-pin.

Must be the dumbest setup on here right now. 768p and GTX1080.

The PSU isn't really the best in terms of quality, can't you spend $50 to get this?

Yeah that's what I was thinking too.

Going to upgrade to 4K soon and needed a GPU.

Yup. Better to have a 1080 and a 768p screen than a 768p screen and iGPU. Must have some roasting fps, aye?

500W is good enough. depends on the quality of your PSU.

 

my 4770K and GTX 1070 take no more than 320W under load, so a GTX 1080 system won't take much more.

Why throw so much money on something that won't work on its full potential? That GPU will be so much cheaper by the time you get better display. I would rather search some used GPUs

Ok thanks for the information aren't those 2 extra pins grounds?

I got it for 400.

Your choice, still a total waste of money

Why not?

 

Assume his CPU takes an outrageous 200W of power.

that leaves 300W for the GPU and other stuff.

of the other stuff, like motherboard, HDDs, keyboards, etc. take (again, estimating on the high side) 75W, then that leaves 225W of power for the GPU. the TDP of a GTX 1080 is 180W, and the factory overclock doesn't increase power target more than 12%. 112% (max power target increase) of 180W is 202W. still tons of headroom, even for overclocking, even with my estimations being on the high side.

Depends.

In 6 months, if Volta comes out, then yes. if volta doesn't come out yet, then a GTX 1080 will still be more expensive than $400 usually, (depends on vega competition) and OP got to experience blisteringly fast FPS on ultra settings for 6 months.

the two extra pins between a 6-pin and 8-pin are grounds, but their most important job is to signal to the GPU that it is allowed to draw 150W from the connector. so electrically, 6-pins and 8-pins can deliver the same amount of power, the GPU knows which one it is, and how much power to draw, depending on the presence of those extra 2 pins.

So, what you're implying is all 500W power supplies are made the same?

What?

no not at all.

I'm just saying that a 500W PSU delivers 500W of power, and 500W of power is enough for his system.

 

I understand that his PSU isn't great quality, but it can deliver 500W of power, and although it's tier 6, it's not a bomb.

Ok, for a second I thought that's what you were saying.

Especially since he plans to replace it in a few months anyway.
