Selling PSU, what should I buy?

post #1 of 6
Thread Starter 
So, I posted an offer 60$ for the psu in my sig.
Seems like the supernova series from evga is the best bang for buck.



I wonder what would be a worthy replacement for my current PSU.

Motivation for replacing:
-Bought in 2010 (end of warranty this year).
-Some one on the forum said the early version of the TX750W were not good. I have the second version which is CMPSU750TX-C. Couldn't find much information about the ripple issue with that particular psu model although.

Some one is willing to take my PSU for 50$ (canadian). Paid it 126$ back in the days.

Should I pull the trigger? The 750W B2 comes at 101.25$ after tax (5%) and MIR. So I will end up paying 50 buck... thinking.gif
I wonder if the G2 750W (132.25$) is worth the 30% price difference?

Please forgive me, but my OCD is going haywire: the dollar sign goes on the LEFT side of the dollar amount.

 

Anyway, the 750W B2 has a good review:

 

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story6&reid=393

 

But he does say this:

 

"Yeah, it's nice to dream about buying one of the more impressive Leadex based units, but if you can't afford one of those you still need a unit that's solid and dependable enough to get you by until you can get one of those beasts."

 

So it leads me to believe that it's a very good PSU, except for the fact that he says "you still need a unit that's solid and dependable enough to get you buy until you can get one of those beasts".

 

With your rig though, you don't have to have anything bigger than a good quality-made 550W PSU.

Yea, I've been considering buying a smaller PSU but with a Oced R9 290 & cpu + WC loop how low can I go really? If you exceed, you have to change the whole thing and I can't afford that. At this moment the 650W and 750W are the same price. Sure thing, I would like to pay less. I don't see the point of 750W as you can't even crossfire. The R9 290 is something like 220ishW. CPU + mobo, let's guess, 150-200? It's getting close to 550W... Plus, I've heard PSU don't like too much nearing their full capacity all the time. With age they tend to perform less as well.
I like the 7 years warranty on the G2 and that is the only reason why I would spend 30% more for it.

The G2s are very high-end PSUs, so we don't have to worry if the power consumption while gaming is near its advertised capacity. These things could easily deliver their advertised capacity 24/7 if it were needed - although never recommended in general (so, you'd never catch me doing it even though my brain knows it would be fine lol). The whole thing about staying away from the full capacity and PSUs aging and not working as well just doesn't really apply to these high-end PSUs because the capacitors are just that good.

 

With an 290 at stock and an overclocked 2600K, your power consumption while gaming would ride about 450W. Since the prices of the 650W and 750W G2s are the same for you, I would just get the 750W G2 and do a little dance. :)

What about the B2? Apart from the 81% vs 87% efficiency, is there a notable difference in performance?

Hmm... after seeing that JonnyGURU.com review, I think the only difference you'd notice is maybe in the packaging and presentation of the product. lol :) Oh, and the normal modularity vs. the full modularity and maybe the paint color. hehe Oh wait! The name "B2" vs. "G2". :)

 

I think the only difference in performance could be in that if you were trying to be a competitive overclocker (like, attending big competitions and whatnot), the G2 might let you pull ahead as compared to what you could achieve with the B2.

 

So I guess you have a good point: why get the G2 when you can get the B2, and I can't disagree with that at all.
