GTX 970 -> RTX 2080 ti - Powerupgrade needed?

[Tech Enthusiast]

Never had a real highend GPU or CPU before, but went ahead and preordered a 2080 ti (MSI Gaming X trio).

 

My rig currently has a 650W 80+ Gold Power Supply. 

The GPU I use is a GTX 970 from Zotak, which is OCed by a lot, combined with a 4.3ghz 4790k.

Testing my current power draw I can get spikes to 400w, but usually end up in the 250w range.

 

I am now wondering if i need to upgrade it anyways. Peoples suggestions for 1080 TIs vary by a lot. Some claim you never need more than 400w, others say 650w is fine for whatever.

The Pinned topic on this subforum recommends 650w as a minimum for an OCed 1080ti.

 

Due to my lack of personal experience with this, i wanted to make sure and ask you guys. Will the 650w one i have be ok, or should i go for the save route and upgrade?

Yeah it's probably fine, hopefully it's not some cheap no name chinese unit though, then it's a fire hazard.

There's also the question of how old your power supply is. If it's at the 4 or 5 year mark, maybe you shouldn't push it. However, each generation brings more efficiency, so the 2080ti should actually consume less power than the 970. Of course, the problem then arises that you ordered from MSI, so if anything goes wrong whatsoever, you're up shit Creek for sure.

You're measuring AC power consumption at the wall, but PSUs are rated for their DC output to the components, which is going to be lower. So your spikes are actually only to about 350W, with actual sustained power consumption around 225W. A 2080 Ti will push that higher, but nowhere near 650W. You're absolutely fine, if the PSU is decent quality.

The 2080 Ti will consume more power than the 970. Around 250W or a bit more (stock), where the 970 is around 175W (stock).

Those are actually pretty bad figures, like 780ti bad.

250W is standard for big GPUs. Titan V, Titan Xp, Titan XP, 1080 Ti, Titan X, 980 Ti, Titan Black, 780 Ti, Titan, 580, 480... all around 250W. That's by design, it's about the most you can reasonably cool.

Thanks, guys.

I guess I won't have to upgrade then. 

 

Now it just needs to be the 20th already. Eagerly awaiting the GPU for some machine learning tests *droll*

Completely false, power efficiency goes up, which nVidia then uses the cram more performance into the same power envelope, the 2080, for example, is rated for a 35w higher power draw than the 1080.

well, you've got the 970 vs 770, at 145W vs 230W respectively, then settling in at 150w with the 1070. Pretty significant jumps, but the 2070 is at 185 now, which is probably due to the new tech in it. I bet it's way lower without AI features.

Supposedly we're going to see a decent power draw bump from the 1080 Ti, so I think we'll start to see recommendations for 650W units become standard for i7/2080 Ti systems.

 

What is your current PSU?

they already were common for i7/1080 ti systems. In fact, I think I've seen more recommendations for a 650W PSU than any other wattage, and for just about every type of system.

Well most systems don't need a 550W unit so the fact that 650W was recommended for so many by your instances is kind of dumb. A 1080 Ti and i7 system could still draw less than 500W so a 550W unit was still fine.

I agree, I find most people will recommend a PSU far above what's needed.

That is the reason i was wondering, yeah.

 

My current PSU is a Seasonic x-Series, 650w

X series is great, it'll be fine with the 2080Ti.

Thanks for confirming.

 

Considering my wife needs a new PSU as well for her 2080 ti (her PSU is 9 years old, I was shocked when she told me a minute ago),...

 

... which of the PSUs listed in the stickied Tier list are currently considered "best"?

Kinda looking for 650 or 750w, likely 750 to be sure. Should also be modular and a big plus would be fanless. 

 

Seasonic Prime Titanium is looking quite sexy, also has 12-year warranty, modular, fanless, titanium certificate etc.

But I may just be falling for marketing buzzwords here. Not into PSU specs at all, so kinda relying on you guys.

Well, the AX1600i and Masterwatt 1200W MIJ are probably the best ones. Probably not worth it for you, and quite overkill for your puny ~400-500W PC :3

 

550-650W should be plenty, even assuming overclocking. For completely fanless ones, there's the Prime 600W, although there will always be some electrical noise. 

Realistically, you probably won't hear the fan of a quiet PSU when the PC is at full load.

That's a fine unit. Keep it.
