Corsair vs550

Posted 26th Sep
okay so the corsair vs550 is a white 80+ certified psu and i have ordered a rtx 2070s but I've read you want gold standard and I don't really understand as I've also seen 42amps on the 12v rail will be plenty on a psu so then I'm thinking I'd be fine, what do you think?

White means it's crap at energy efficiency and you'll be wasting alot of electricity.
You should be fine

Well the efficiency table suggests it's at 84 for efficiency

And the "white" rates it below Bronze, Silver, Gold, Platinum, Titanium.

Yeah of course
2c3amh26/09/2019 10:20

Yeah of course



Which makes it bad, as white is the lowest rated. The only stuff below that is unrated.

It's only energy efficiency though right? So the 2070s will run fine?

I don't know anything about top of the range gpus. You'll need to check what power connections are needed for the 2070 and what you've got on the psu.

As long as you have all the power connectors then i assume it will be fine.

Well i have an 8 and a 6 pin , i think it requires just an 8 but maybe both, I'll have a look
I wouldn't trust any expensive component with a Corsair VS series, I would upgrade to atleast a CXM. Have a look at linustechtips.com/mai…st/ and get atleast a Tier B.

Why though?

Cheaper PSUs use cheap components that don't provide as clean a power to your system (reducing their lifespan). They also have a higher chance of blowing and taking your components with them (this has happened to me).

Well I've used this power supply for two years with a 1050ti

And it might last another 2, it's just not worth the risk when PSUs are one of the cheapest components in your PC. A CX550M for example is far better and about £60, compared to almost £500 for a 2070S.

Oh don't get me wrong i see your point, just monies so was hoping it wouldn't matter

No it doesn't. The lowest rating doesn't automatically make something bad. While all of the above are true the differences and risks involved are small.

A PSU like the VS550 is fine and certainly not worth the cost to replace it.

So should be fine for the 2070s then?

Well it's a 215W graphics card so as long as the rest of your system is under 335W and your PSU has the appropriate connectors it's fine.

My understanding is a low effiecency psu would mean more lost energy. That lost energy would be heat wouldnt it, and heat is bad for a pc system therefore lowing the life of components.

One reason why high efficient PSU's can have hybrid fan modes, or even go without one at all.
Another thing. PSU's are most efficient usually at 50% load, so if heat and efficiency is important to you, consider that too.

1050ti isn't exactly power hungry

Let's assume the system uses 275W while gaming. An 80Plus PSU is somewhere between 85% and 88% efficient at 50% load 230V which means 38-48W of heat, while an 80Plus Gold PSU is 92-94% efficient or 18-24W of heat.

So we're talking 20-24W of heat difference between the two. That's about the same variation as you see between different RTX 2070 Super cards:
techpowerup.com/rev…tml

And of course almost all of that 275W of power draw is being converted to heat inside the case by the other components anyway.

Its not a case of "anyway". Anyway is the reason why it's even more important.
Okay so would the vs550 be okay then?

I've decided to buy a new power supply I'm looking at the corsair tx750m

Check out 650W EVGA Supernova G3 or RMX

Well the tx750m had good reviews and has more wattage so i got that
