Strange power supply mix-up

darksora269 · May 27, 2013

I was looking for a new powersupply for my new build. Want to bury a platinum into it. I seen that there was a different brand than one but... You know what, just take these links.

Now the weird thing, they both come from the pcpartpicker source. Is there any difference from the XP and the XP2 or is it just a weird rename or something?

darksora269 · May 27, 2013

Looking at the two links and their cable inclusions, they look the same. Maybe I could go for the one on Amazon and save myself a few dollars. What do you guys think?

ksham · May 27, 2013

Both are excellent power supplies. You won't go wrong with either one. There are some improvements on the XP2 over the XP. For one, it is slightly smaller. And probably some other stuff under the hood. So no, it's not a weird renaming. Don't know why you would say that. That aside, score-wise, I would still score them each with a 9/10. I took off one point because price/performance value is not great. That's $150 for 660W. Anyway, it really is your pick.

ksham :

I'm mainly going for them and maybe some other brands like corsair due to their full modularity (New word.

).

Some gold rated PSU's will also come into my line of sight. I'm not going for much power, just a single 7970, I might upgrade in the future but I doubt it. One would be enough for me.

Thanks.

Edit: I learned from past experiences that you don't need too much power. And I'm happy to get that much power for that high of quality appeals to me. I have a rosewill 1,000w Bronze and it works, just, too draining on the energy I feel.

ksham · May 27, 2013

There are cheaper modular PSU. Unless you must stick with Platinum or Gold because you really want to save that extra $2-$3 per month.

darksora269 · May 27, 2013

ksham :

In a way, saving that little bit of extra money will be more than worth it.

ksham · May 27, 2013

Well, you can get a good quality 80+ Bronze 650W PSU for about $60. So that's a difference of $80. So let's say you're using 330W (50% load of the 660W) for 24 hours a day for a month. And let's say you pay 12 cents per kilowatt.

So for the Bronze, you would pay $33.54 a month. For the platinum, you would pay $30.99. You saved $2.55. The cost difference between the PSU is about $80. To pay it off, you will have to use it at 50% load 24/7 for 31 months.

Of course, that's an impractical case. You're not likely to be using it at 50% load all the time. Most of the time, it would be idling or shut down. And other times, it may be 50% or higher. So the actual payoff time is usually longer than 31 months.

So if you think that is worth it, go for it.

They are the same supply EXCEPT they had some coil whine problems and the 2 denotes new parts that have fixed the issue. I would buy the 2 and pay the shipping

jnkweaver · May 27, 2013

Ksham could you explain your math? I think you made an error.

ksham · May 27, 2013

@jnkweaver: I don't think the XP has that issue anymore from what I read on reviews from johnnyGURU and TPU. Oh did I make a mistake? Where at?

1 month = 30 days. You could count for 31 days. So by my math, I lost 5 days a year (6 in leap year). 10 days in 2 years. So it should've been 30.75 months.

Bronze: .33 / .85 * .12 * 720 = 33.54
Platinum: .33 / .92 * .12 * 720 = 30.99

jnkweaver · May 27, 2013

I am not disputing your point btw but I do think you have to compare like supplies. Looking at Newegg I find a Bronze Seasonic semi-modular 650W for $90, The Gold fully modular 650W for $100, and the Platinum he is looking at 660W for $140 + 9 shipping.

By standards (no reviews) the Bronze is 85% efficient at 50%, the Gold 90%, and the Platinum 92%.

At your 330W draw scenario the Bronze takes 388W off the outlet, the Gold 367W, and Platinum 359W (divide the system draw by the efficiency). the cost per day at $.12 KW/hr is
Bronze 1.12
Gold 1.06
Plat 1.03
Taking the Bronze as the basepoint it takes 167 days to break even on the Gold and 656 days to break even on the Platinum.

I agree that 330W continously is unrealistic unless you are bit mining so You would have to decide how much you will use your computer.

I presently think that the Gold is a much better bargain.

ksham · May 27, 2013

Nice; so those are the same numbers that I have, except I used 92% on Platinum 50% load @115V USA. I also didn't round them. I just plugged them straight into the calculator. I guess some floating point is rounded up somewhere.

The one I was thinking of was the Corsair TX650 V2 which you can get right now at $59.99.

jnkweaver · May 27, 2013

I agree you should do the math before buying. I ended up with the Seasonic 750 gold in my machine after a sale put it cheaper than the 650 Gold

ksham · May 27, 2013

Very nice. I like PCPartPicker's daily notifications on price drops. Picked up some good stuff with that. Most of which aren't in use at the moment. Just good to have some spare parts around.

darksora269 · May 27, 2013

Now reading your message, I'm likely to pull back and even put my money into this. http://pcpartpicker.com/part/evga-power-supply-120pg0750gr Save myself a pretty penny but still have superb quality.

darksora269 · May 27, 2013

I might actually go for this > http://pcpartpicker.com/part/evga-power-supply-120pg0650gr
Better priced and I'll still have more power than I need.

Thanks for the tips guys.

I wouldn't. I would stick with Antec, Corsair, Seasonic, and XFX. Also those made by Seasonic like the Rosewill Capstone. Super Flower is another outstanding maker. Delta and Channel Well are very Good, after that they go on down. Honestly don't know about FSP one way or the other http://www.tomshardware.com/reviews/power-supply-oem-manufacturer,2913-6.html

darksora269 · May 27, 2013

ksham · May 27, 2013

For 600W - 700W, I would recommend Antec, Be Quiet!, Cooler Master (Silent Pro models), Corsair (TX, HX, AX models), Enermax (Platimax, Revo models), FSP (Aurum models), NZXT (Hale90 models), OCZ (ZS, ZT models), PC Power & Cooling, Rosewill (Capstone, Hive models), Seasonic, Silverstone (Strider models), Super Flower (Golden models), Thermaltake (Toughpower models), XFX.

jnkweaver · May 27, 2013

Oh god stay away from silverstone, Cooler Master and Thermaltake.

What is your system and your upgrade plan and we can recommend a good inexpensive psu.

darksora269 · May 27, 2013

ksham :

Alright, I'll check them out.

I'm mostly trying to get a PSU that is extremely modular, if not fully modular.

darksora269 · May 27, 2013

jnkweaver :

That would be good.

Here's the list: http://pcpartpicker.com/p/10z7n

ksham · May 27, 2013

jnkweaver :

Not all of them are bad.

Just like Rosewill. Some bad, but there are a few highlights.

jnkweaver · May 27, 2013

If this is a gaming build you are over the top with the memory. 8Gb is considered the sweetspot nowadays in a 2x4 configuration.

With the money you save you can get a 120GB SSD.

If you are going to stay with a single card than 500W is enough, if not then you need 850W.

Once you get over $1K it is worth it to go intel chip.

Let me know if you intend to stay with the single card arrangement.
