Question Big difference between 500 and 550 psu?

[Razvan_aga]

Hi guys, I want to upgrade my GPU from 1050 to 3060/3060ti.

Does 50W makes a difference?

Since i have this PSU Seasonic S12III-500, 80+ Bronze, 500W

And the psu calculator sites recommended 550W.

Or should i upgrade my PSU first and then my GPU?


My rig now:
Ryzen 5 5600
16gb ram 3200 MHz
1 ssd m2/ 1 ssd sata/ 1 hdd 7200 rpm
4 case vents

That PSU is not sufficient quality, or wattage, for that GPU. Seasonic has some great PSU's, but that isn't once of them.

That PSU is more like junk. What sort of units do you have access to?

If you want to go with an RTX3060Ti, get a reliably built unit with at least 650W of power at the entire system's disposal.

That's a better path for an upgrade. Making sure your structure is reinforced before adding on bits and bobs.

So i found these psu's

be quiet! Straight Power 11 650W, 80+ Gold, 650W, 93% efficiency aprox 137 euro

SilentiumPC Supremo L2, 80+ Gold, 650W, 92% efficiency aprox 88 euro

be quiet! Pure Power 12 M, 80+ Gold, 750W, 92% efficiency aprox 132 euro

Sursa ASUS TUF GAMING, 80+ Gold, 750W, 92% efficiency aprox 160 euro

But i gotta get some cash first

These are far more appropriate PSUs than your current one.

These are the only available ones, for now, but i will ask again when i get some cash. Thanks.

I would certainly not upgrade the GPU until I got a better PSU.

Is there any posibility to damage something else than the psu? Or just random shut downs and PSU failing?

PSU could die and take your hardware with it.

Seasonic S/M-12 III is a Seasonic platform design, but not actually built by Seasonic. They subcontracted that line out to RSY, whom so far doesn't come close to Seasonic in house standards, but it's such an old platform I'm guessing they don't really care. It's the lowest quality Seasonic branded psu there is thats still manufactured.

Is there a difference in 50w? Absolutely. There are no Good quality 500w atx psus I can think of, but there's a bunch of 550w that rate from Good to freakin Awesome.

That little 50w can make a big difference in power delivery, stability, boosts, dependability, reliability depending on the choice of psu.

DC voltage in its purest form is a flat, straight line, no up/down. AC voltage is what alternates, up/down. If you use a psu with such poor filtering that your DC components (like cpu, gpu, ram...) are getting DC voltage that looks more like AC voltage, they will complain in a big way, burn out, quit, die, bluescreen, blackscreen, underperform, crash, freeze and generally run like crap.

The psu is the single most important part of any pc. It powers Everything and Everything is affected by it. It's literally the Heart of the pc, and if it's got a bum ticker, nothing good will come of that, only bad to terrible things.

3060/ti isn't all that cheap, it's an investment for many ppl, so while a 500w Seasonic S-12 III with a 65w Ryzen will be ok power-wise, you'll need to realize that psu isn't doing anybody or anything any favors, and could very well end up costing you more than the price of a decent psu to start with.
