Did I make a mistake getting this PSU?

Hi everyone,

So I've been buying all the parts one by one as good opportunities/sales come by. I got an MSI MPG A850G for my build and I'm planning to get a 5080 Suprim.

So far, my build is as follows:

CPU: 7800X3D
Mobo: MSI x870e Tomahawk
Ram: Gskill Trident DDR5 16x2 6000MT 30CL
Case: Corsair 4000D frame
PSU: MSI MPG A850G

About to add:
5080 Suprim
Still need to buy a cooler and fans and while I know it may not be necessarily needed, but I would like a 360 AIO.

I got a really good price for that PSU. Should I have gotten 1000W instead?

Thanks, appreciate any directions I can get.

If you can send it back try get a 1000 at least that way your good for a while.
 
I don't know this PSU/model personally, but as long as it's a decent PSU, I cant see it being a problem, FWIW people used to run high end Intel/AMD CPU's paired with 4090's with the Corsair SF750 in SFF builds for example, and it was proven to be fine :)
As long as it's got a good spec, reviews well, decent warranty, and you got a good deal, then don't worry about it :)
 
What everyone else said.

There's a weird thing with power supplies where people think they have to massively over spec them.

Don't get me wrong, I'm a big advocate of not skimping on the PSU, but that's not the same as wasting money on something that has way more capacity than I'll realistically need.

As long as it's a decent unit it's fine.

Many over spec for silence. Granted it is on the more niche end as most are happy to run with some noise especially headphone gamers. On my build the loudest part was the psu AX1000. Could hear it kicking in during gaming. I over speced the psu and now never hear the psu, pretty much stays within the fan off range.
 
My buddy and go to gaming guru, says it’s very boarder line if this PSU will run the 5080 stably or longterm. He also says the AIO and fans will very much be needed with the air cooled version of the 5080 suprim in that case, and recommends the AIO 5080 suprim.

Lol

The recommended PSU for that card is 850w.

It's the same for audio.

I've not seen the PMPO rating for years. 10,000W from a Aiwa apparently :D
 

You need to stop listening to your friend, he doesn't have a clue and he's costing you a lot of money unnecessarily.


Typical gaming loads for a 5080 are around 380W,


The Founders Edition twin fan version of the 5080 offers ample cooling, in fact it's the only version of the card I'd somewhat recommend for close to £900. Spending £1400 on a 16gb GPU that's not much faster in reality than a £550-700 9070XT or 5070Ti is beyond insane, especially with the Super variants less than six months away. I'd rather pony up another £400 for a 5090 FE at that point, the 5080 is crap value to begin with let alone the more premium models.

It really isn't... X watts requirement @12v DC is a specific value it either is or it isn't, there's no vague equivalent measurement such as PMPO that's sometimes used in cheap hifi gear to make it sound more powerful than it actually is.

There is very little difference in price between the air and AIO versions. Apparently the suprim will pull over 450 watts., and that’s going to get toasty for an 850 watt gold rated PSU. Yes Nvidia prices are insane.

He really is very well clued up when it comes to this end of the market.
 
He's not clued up, quite the opposite, he sounds like an idiot.

I don’t think so. A 1000 watt platinum is a huge cut above a 850 gold. Not to mention £40 off and 17% cashback. So yeah seems like good advice there. Spending an extra £20 on the AIO version of a 450 watt card that’s notorious for being difficult to cool also seems like great advice.

Platinum /gold just relates to efficiency, as there's always an efficiency loss when converting AC to DC, which is essentially all a PC PSU is, it's an AC/DC converter.

The efficiency difference between gold and platinum is actually really really small once you start doing the maths and comparing how much more or less it will affect your household electricity bill. Especially comparing a gold PSU that costs about £100 to a platinum for twice the price.

It's not 100% more efficient, probably only something like 2 or 3% more efficient, so your very very unlikely to ever recover that sunk extra purchase cost over the lifespan of the PSU.

Your mate is an idiot and he sucks at maths.
