[SOLVED] Wattage on the edge.

[gamerbrehdy]

So here are my specs:

CPU: intel -7-7700
MoBo: ASUS PRIME Z270-P
RAM: 16GB G.SKILL TridentZ RGB 1600MHz
PSU: 650W

I'm not mentioning my GPU. Here's why.


A very close friend of mine just upgraded from his Gigabyte Aorus GeForce GTX 1080 Ti Waterforce Xtreme Edition to a dual RTX 2080 Super setup. Why? Litterally no idea.
He offered me the 1080 ti for free, because he's probably never going to use it again. So here's ME, wanting to swap my old 1060 3GB for it. But the power consumption of the 1080 is 600W and Im not sure if my PSU is powerfull enough, because TechPowerUp GPU-Z says that im only using around 30W...

Do I need to upgrade my PSU if I want to use the 1080?

What exact PSU make and model is it?
Remember wattage is useless without quality.

Any random 650W probably not.
A good quality 650W, perfectly fine.

The 1080Ti does not consume 600W - it's more like 250W/280W

But the power consumption of the 1080 is 600W

600W is probably the generic, safe "recommended PSU wattage" that the graphics cards makers come up with to cover their bases. They don't know if you have a modest CPU and only an SSD drive, or if you have a top-end CPU, overclocked, with multiple spinning hard drives in your system, etc...

But, as @PC Tailor pointed out - a good quality PSU is a must. What is the exact brand and model number of your existing PSU?

Also, see the link at the bottom of my sig - that should give a pretty good summary.

The PSU is way more important than most people realize. A good one is unremarkable, because everything works. A bad one, even if of high wattage, can crash and burn (sometimes literally) and take out your expensive PC components with it.

Can't say because we don't know what kind of PSU it is.

I believe its a Corsair PSU, definetly not some second hand pile of deuce. It’s 80+ if I’m correct. Need to check it at home this afternoon.

 

[gamerbrehdy]

it's the Corsair VS650.

 

[PC Tailor]

it's the Corsair VS650.

Well it's the worst PSU in the Corsair line (outside of older units) but the newer ones are OK but personally I wouldn't use any VS series for a high load gaming system myself. Bare minimum would be a CX/CXM IMO.

80+ bears no relevance to quality, only looks at efficiency.

 

[jonnyguru]

it's the Corsair VS650.

So, wattage isn't an issue here. 650W is more than enough.

But if it's the old VS650, it's not going to handle the transient spikes of a 1080 Ti card. If it's the newer VS650, it will probably work. I've had issues where just trying to fire up Furmark with a 2080 Ti and a VS650 will cause the PC to shut down.

With a card like that, you really should be using a PSU with an LLC resonant mode topology.

Any suggestions for a new PSU?

Several.

One idea is a CX550 (non-M). Another is the TX550M.

Of course, you could just TRY the VS650 first. It's not like it's going to burst into flames if it doesn't work. It's just going to shut down or restart.

Which version of the VS650 do you have? What color is the side label?

Just a black label with VS in orange and 650 in white

 

[bignastyid]

Is it the waterforce that uses an AIO or one that needs to be part of a custom loop? If it's the version that just has a waterblock then you'll also need to consider the power needs of the loop.

If I recall correctly, that orange VS is the one that should be avoided like the plague.

It is yes, the orange ones are the older units, it's the grey label you want.

As for OP, Even then I'd at least go a 2017 platform CX for a higher end gaming system.

Yeah. That's the old 230V only VS. It's not going to like that 1080 Ti.
