with that said TwoCables, what PSU do you recommend for under $60. sorry stupid budget.

Can you do $62.98?

I'm referring to my post above, #98: https://www.sevenforums.com/overclock...ml#post2413706

That's a direct link to my post. I tried to change the link's text, but it's not working. Sometimes it does, and sometimes it doesn't.

It's been my practice to buy the biggest PSU I can afford, within reason, so I am using around 50%-60% of its rated output on max.

It would be better for the sake of maximum average efficiency if your average PSU load were around 50-60%, not your max load:

On PSU Efficiency

PSU "50% Load" Myth




With the way things are going, each new generation of CPUs and GPUs requires less power than the previous. In some cases, almost the same, but not more. So it would have to be a pretty big upgrade...




Good quality-made PSUs like yours and mine, as well as pretty much 90% of the PSUs on the list below, will have absolutely no problem with heat or anything else because they're designed to easily deliver their rated (continuous) wattage 24/7 if it's ever needed. Most of them are rated to do so at an internal PSU temperature of 50°C. A few are rated for 40°C, and even fewer are rated for 30°C:

FAQ: Recommended Power Supplies

The only kind of PSUs you have to worry about for the kind of things you're talking about are PSUs that are generally never recommended by any of the PSU experts (and for good reason). So having a PSU like the HX650 for a system that will never pull more than 300-350W from it is absolutely unnecessary overkill and it reduces your average efficiency to below what's advertised. With your PSU, your system could be set up so that it pulls 500-600W from your PSU while gaming and it would be just fine because it's designed to easily deliver 650W 24/7 if it's ever needed, and it's rated to do so at an internal PSU temperature of 50°C.

I checked PSU recommendations for various GTX 650 Ti's and of those which listed a PSU minimum, EVGA and Galaxy, both stated a 450W minimum PSU is recommenced. Another brand, Zotac said 650W.

I do own a Rosewill 500W PSU and it performs as it should.

Those recommendations are for peak-rated PSUs, not continuous-rated units like ours (or any of the units on the list of recommended PSUs for that matter).

Take a peak-rated 450W PSU for example. The +12V capacity would be at around 324W, which is 27A. Now, today's systems draw most of their power from the +12V rail because most of the parts in a modern computer run on 12V power. So a peak-rated 450W PSU with a +12V capacity of 324W means that it can likely deliver about 350W continuously, although probably rather poorly because no good quality-made PSU is peak-rated. Either way, having a +12V capacity of 324W means that it could be sold as a 350W continuous-rated PSU just like how the HX650 is sold as a 650W continuous-rated PSU.

Now, I don't know why or how Zotac would recommend a 650W peak-rated PSU to power a system that has one GTX 650 Ti in it because a peak-rated 650W PSU would have a +12V capacity that's no greater than about 480W, or 40A (and that's being slightly generous). There are a few quality-made 520W PSUs on the market that have a +12V capacity of 480W/40A. So, unless Zotac's GTX 650 Ti pulls about 100W more than all other 650 Ti's, that 650W rating has to be for 2-way SLi.

I apologize for all of this, but I know that these posts are publicly accessible without a SevenForums account, and so as long as I'm around, I want to make sure that the information is as accurate and as correct as possible.

This advice is always the best to consider you have to figure in quality and what you yourself are looking to achieve a system like our is going to draw more power then an intel period so I still would get something about 600w to be safe max out put should be right where two cables says it should but underload the power draw for AMD is much higher im afraid and you do want to go with a good 12v rail some come with two or three but you need atleast one good 12v rail 30 or higher personal preference some require like a 25 personally never used Roswell I heard they are very good but if you think that corsair is subpar I can find you a better psu with that same budget

When did I say that Corsair is subpar? All I said is the CX430/CX500/CX600 are way overpriced. They're only rated for 30°C (internal PSU temperature), and they have cheap capacitors in them. Besides, most of Corsair's PSUs are overpriced these days anyway. For that reason, I usually try to avoid recommending their PSUs because equal or better PSUs by other brands can be had for the same price or less.

Anyway, the 450W Rosewill CAPSTONE Series PSU is more than enough power for his plans both now and in the future. Like he said, he might get the 660 Ti, and that doesn't draw all that much power either. I'm not recommending the CAPSTONE Series PSU because it's made by Rosewill; I'm recommending it because the PSU that Rosewill used to make it is the Super Flower Golden Green which is a high-end unit.

If you can find a better PSU for under $60 than the 450W Rosewill CAPSTONE Series (which is $62.98 after shipping), then be my guest because this is purely for Quadrider10's benefit.

I usually recommend higher end Corsair PSU's because they are made better and the attention to detail is awesome. Their lower end models seem to have mixed reviews. Also, there always seems to be a few of their models on sale. Rosewill makes decent products as far as I know, they are Newegg's house brand and can usually be had for a little cheaper than the competitor. You need to figure out if you want to get a PSU for THIS configuration, or one slightly more powerful to account for upgrades. I know hardware is using less and less power, but you never know when a great deal on a high-end part will pop up or if your computing needs will change. If you buy a PSU that will JUST handle this configuration, be prepared to buy another one if you do any real upgrade. Good 600 watt power supplies are on sale everyday and can be had near your budget. If I were you, I'd save up another month or so and get a PSU that will handle future upgrades.

My take on this is that if he's looking at maybe being able to get the 660 Ti, then money is probably always tight. Even so, he could get the GTX 680 if he had enough money and still have more than enough power with the 450W Rosewill CAPSTONE Series PSU:

GeForce GTX 680 SLI review - Power Consumption

This review means that his gaming power draw with the GTX 680 would be at around 325 to 375W which is easy for a high-end 450W (continuous-rated) PSU.

Then there's the power draw of the GTX 660 Ti: it's similar to the GTX 670, but less by about maybe 20-50W. So here's the GTX 670:

GeForce GTX 670 2 and 3-way SLI review - Power Consumption

This review means that his gaming power draw would be at around 275-350W. Take 20-50W from that for the GTX 660 Ti.

So, the 450W Rosewill CAPSTONE Series PSU isn't one that will JUST handle it. I mean good grief, it's overkill for his system as it is with the 560 Ti. Then upgrading to the GTX 660 Ti which pulls less power means it'll be even more overkill. So, I'm not worried about recommending the 450W Rosewill CAPSTONE Series PSU, especially because it's very close to his budget at $62.98 (his budget is $60 or under).

True ya gotta pay attention to which Corsair PSU you get, the HX 650,et al, is built by Seasonic, other models are by others. I suppose all are made to Corsair's specs since they honor the warranties on all.

Kelly I though Rosewill was Newegg's house brand too, but: Rosewill.com - Computer Case, Power Supply, Computer Accessories, Networking, Peripherals. Price, Quality, and Services.

They are indeed Newegg's house brand. That's just the website for it.
