EVGA G2 550W Vs GQ 600W.

[damocles]

I'd planned to get a Fractal Design 650W Edison to run an Ryzen R5 2600/Radeon 5700 setup but it's no longer available.

I can get either a EVGA G2 Supernova 550W or the GQ 600W. The 550W is on special so they are basically the same price.

AMD recommends 600W+ for the 5700 and the shop is telling me the GQ is the better PSU for my situation.

I don't mean any disrespect to the shop, but in my mind I was thinking that the G2 is the higher specced model and the 5700 (non-XT) isn't particularly power hungry.

I like that the G2 comes with a 7 year warranty where the GQ is 5 (still good of course).

Is the GQ really better in this situation?

(I could also pay a bit more and get the GQ 700W)

The G2 overall is a better PSU in my opinion, and if I had to choose between the two, I'd go with it. The GQ is also a 650w unit (not offered in 600w that I've seen): https://www.evga.com/products/product.aspx?pn=210-GQ-0650-V1

The GQ series (made by FSP) was OK, but it's a step below the G2 series made by Super Flower (who also makes the G3 for EVGA).

Are power supplies the EVGA G3, Seasonic Focus Plus, or Corsair RMx not options in your location?

Thanks for the response.

They are definitely 600w and 700w GQs according to the website and they also have pictures of the boxes.

The Corsair RMX 650W and G3 650W are available but are a fair bit more than the G2 550w (about USD25).

It's hard to find Seasonic here.

They must be offered in your region, but not here in the U.S. Also, I believe they have been discontinued in our market (replaced by the G+ line).

So, I'm not sure what they changed design-wise to make them odd total power (such as 600w and 700w). The GQ models we had here were all 650w, 750w, etc.

So I would personally still go with the G2 because Super Flower makes great units, and that they haven't changed the components / topology to get it to an odd power rating. But as far as I know, the G2 has been phased out in our market for a while, replaced by the G3. And based on their availability from places like Newegg, it looks like they are simply clearing out any remaining stock (they only have two sizes in stock).

Thanks very much. I'll get the G2.

I doubt it will struggle with a non-overclocked Ryzen 2600 and non-overclocked 5700.

Sometimes it's hard living in a technological backwater!

It shouldn't have any issue at all. Anandtech reviewed that card, and they used a 9900k as the CPU which easily uses more power than yours does. They hit a max total system load of 231w using a synthetic benchmark.

I just wanted to say thanks again.

I ended up with a Corsair 650w that the retailer said was probably better than the G2 (and the extra 100w is nice).

It was an open box special. Only ten dollars more than the G2.

Model is RM650i. 80+ Gold.

Retailer is pretty trustworthy, so I'm assuming it's decent.

That's a very good PSU as well.

I recommend you install it with the fan facing up (into your case), as the fan only comes on when needed, and there's no way to turn the "fan stop" feature off like you can on some units that have a switch on the back. If you install it with the fan facing down, the heat from it will rise and sit inside the PSU housing (which can shorten the life of the unit). With the fan facing up, the small amount of heat can rise and be pulled out by your exhaust fan without building up.
