To what?

 

That’s the important bit.

 

Single GPU, 550 is more than fine unless your crazy with OCing, what is attatched to it and installed into it.

 

I have a 550 but current PC is calculated for under 400 with an RX580 in it.

 

I guess I could power a 1080 with it but a 1080ti might be pushing it...

 

I compared across a few PSU calculators to be sure.

i5 8600 - RX 6600 - Fractal Nano S - 1080p 144Hz

Actually, that wasn't my point.

 

True, a good 550W may not actually be able to put out 550W, etc.

 

But my point was group regulated power supplies vs. LLC, etc. topolofies.

 

Group regulated units, when paired with higher end graphics cards like GeForce GTX 1080xx or RTX and AMD Radeon Vega 64, etc. have a high slew rate that causes the transformers to sing louder than a banshee.  And many times, the transient spikes will cause the PSU to shut down altogether.

 

A lower price PSU like the two he's looking at will work for now, but once he upgrades the graphics card, he'll be going back to buy yet another power supply meaning he's saved zero money in the long run.

 

I wouldn't have any reservations using that Corsair VS with an RX 460 or 470, GTX 1030, 1050.... But I would get something like a CX (non-M) or higher for a higher end graphics card.
