The past page or two has illustrated the problem with the use of tiers, vs. having a go/nogo list. The "Go" list would basically consist of everything on Tier-1, maybe some from Tier-2; all stuff we'd buy ourselves. On a budget, there may even be some safe Tier-3 models on it.
The "NoGo" list is basically everything on Tier-5, and maybe a few from Tier-4 that are known to be missing protection circuits (e.g. some Coolermaster); stuff we'd insist be replaced if we saw it in someone's rig, regardless of symptoms. Anything else might not be a reason to run screaming from the room, but they aren't things we'd buy ourselves.
 
The PSU I'm looking at right now (EVGA 750W) seems like a perfect deal: modular, 750W, good brand, and "HIGHEST QUALITY JAPANESE NIPPON CHEMI-CON SOLID STATE CAPACITORS
Get the most reliability and greatest performance with the use of the highest possible quality Japanese solid state capacitors."

Yet the PSU Tier list says "No Japanese capacitors found. Only Taiwanese capacitors and may even include Chinese capacitors. Very basic safety circuits or even thin gauge wiring used. Not for gaming rigs or overclocking systems of any kind. Avoid unless your budget dictates your choice." and lists the EVGA 750W NexB series under that.

I'm confused on what to go with! All in all it looks like an amazing PSU.

Don't confuse the EVGA B1 with the EVGA B2. The B1 you linked above is not very good. The B2 is made by a different and better company and is a great unit.


You could just get this-

Lol you'll have to forgive me, but it looks like I'm getting very confused tonight:
"EVGA NEXB 750W": http://www.newegg.com/Product/Product.aspx?Item=N82E16817438007
The PSU I was talking about: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438025

Does the PSU I was talking about still look like shite? (it is apparently NOT the NexB).

And if so, I'll just stick with my current PSU. My only concern is wattage. Will 550W be enough to support a 280x? Yes, I know that some suggest at least 600W but I'm on a tight budget here and almost every calculator, even eXtreme PSU calculator which I plugged in every part of my PC into, said I would only need 475W recommended.

I don't need the "best of the best" or a "tier 1" PSU, I just need one that will work and not blow my PC up (I can get a better PSU later when I have the money.. currently the GPU and CPUs are more important to me mates!!)

Thanks everyone.
 
Yes, it does. That's the B1 series unit, which IS a lower quality model. The designation is there in the model number. B1.

Yes that is a B1 model. It says it in the name. Not very good at all. The B1 and G1 units are older and use low quality components. The B2 and G2 model are newer and are much more reliable. Like I mentioned earlier, they are made by different companies. EVGA was smart to make that move.

You need to change this way of thinking. The psu is the single most important part of your build and of every build. It is the heart of your system. You cannot cheap out on it. A great cpu and gpu mean nothing if they are not supplied with clean quality power, and a bad psu can RUIN your entire PC.
You don't have to spend $100s on a great psu. The XFX I linked you is $50. Yes it's powerful enough for a 280x.
 

Okay. Thank you for your help! :)
 
Does this PSU look sufficient as well? Reason(s) being I already have it & it's modular.

 
Hi. I recently bought A Seasonic G550 and I'm running only HD7750 Sapphire, AMD 6800K, etc. I used a generic power supply for 2 years now but when I changed to the seasonic I started having grounding problems, I mean small shocks at the screws at the back of my case Coolermaster N200. So now I don't know what to do since I cannot open my case when the computer is turned on because it shocks/grounds me. There was no issue of grounding when I was using the generic Electron PSU. I'm guessing too much power? because the PSU i used before uses the ATX 4 pin only , my board is 8 pin, the Seasonic is 8 pin, it works with 4 pin but I plugged both pins. Sorry it's a bit complicated any help please.
 


I own ans use a BP500 Plus in my main PC. Definitely not a bad unit.
 


Thank you. That's what I figured, and it has nearly perfect reviews all over Newegg. The only thing I'm concerned about is a few reviews mentioned that when it goes, it takes other parts with it. (This is years into the use of it). Should this concern me..?
 


I don't know why you would buy a unit like that when you can get a Seasonic brand power supply for less money and know you are getting one of the best made power supplies on the planet....

SeaSonic S12II 520W 80+ Bronze Certified Non-Modular ATX Power Supply $57.99 - 10% off promo = $52.20 Promo good till Sept 7

SeaSonic M12II 520W 80+ Bronze Certified Fully-Modular ATX Power Supply $65.99 - 10% off promo = $59.40 Promo good till Sept 7
 
A grounding issue usually isn't the psu problem, grounding is performed by the case being attached to the power cord attached to the wall plug.

Did you use the new supplied cord? Reuse the old cord? Is the psu firmly attached to the case with all 4 screws? Is the wall plug loose, either in the wall or just old and not tight?

An easy way to tell if it's related is with a multimeter on the continuity setting. With the psu unplugged, hold one probe to the round, center prong, and start touching the case metal with the other probe. You should get a beep if it's all connected, or the needle should peg at maximum if it's an analog multimeter. If it doesn't, the psu isn't seeing a ground to case. Also check both ends of the cord, again, should beep. If it doesn't, the cord is broke, use a different one.
 
Because it's $15 more and doesn't cut it in wattage. Again, I don't need the best on the planet as long as mine will work and supply clean power.

 


You do know that while these are good units they are an older group regulated design and are not compatible with Haswell low power C states right? The G series or one of the many units based on that platform is a much better recommendation. The S/M 12 II is an outdated design.
 


Mark, he didn't say anything about buying it, he said he already had it and wanted to know if it was ok to keep or should be replaced. While it's not one of the greatest units out there, it's not terrible at all.
 


Exactly. This is what I needed. ^ Thank you.
 
Well, ok, so its an older model, and does not support C6 states. I am not using it for a laptop. In fact, probably nobody on this planet is.

And my system is almost never idle. I run Folding@Home in the background, except for when I am gaming.

And what power supply did I buy back in May of 2014 when I built this system? I went to Amazon to pull up the old orders I made at that time. Result? Seasonic M12II-850 BRONZE ATX 850 Power Supply. And yes, I have a nice little Haswell I5-4670K CPU too.

It works. It works well. And I have absolutely no regrets about having this power supply. It has performed flawlessly for me, and I fully expect it will for many years to come. After all, this is a Seasonic unit. Old design or not, it is still a high quality power supply.
