Hello

I have spent months trying to figure out which PSU to buy.
I came to the conclusion that the Seasonic G series are among the best. I am on a Prodigy M case so I will buy a short (160mm or less) PSU with at least 600W so the fan barely spins. I plan to OC a little, no SLI.

Main problem is it's out of stock here and can't find in any other place. Another thing is that lately there have been a wave of new PSU's and I might be missing something interesting.

Antec TruePower Classic
Antec TruePower Gold
Silverstone Strider Gold S
Enermax Revolution X't
Corsair RM

The first 2 nobody helps me on the Antec announce thread here, nor any reply from my direct question to Antec these past days. Don't know the difference between both nor their release dates.
The Corsair RM is one I don't like because the manufacturer, also Corsair has built a very bad reputation. Then we have Strider Gold S and Enermax Revolution X't both which I don't know anything about. I also don't want to omit naming the Seasonic X 650KM3, it's not new and it showed a rather high ripple on review tests but I want to hear your general opinion as this is sold as the best Seasonic out there. Mainly there's one phrase over the Antec thread that stuck to my head that said that "fanless mode provokes tic noises", fanless might sound good on paper but I'm also on the opinion that constant harsh changes of fan speed or constant spin/stop cycles do more bad than good, not only the change of noise is more noticeable than a constant faint noise, but I think it damages the fan bearings earlier, what's your take on this?
What worries me most about the Seasonic G 650 is mainly the fan, Adda branded vs the Sanyo Denki from the X series...
 
The PSU's you should be looking at are:

- XFx
- Corsair AX Series
- Seasonic
- Antec

All the above are built by Seasonic, who are the best in the business. You also have Silverstone, BeQuiet and Enermax as alternatives.

What is your spec?
 
The problem is as I stated above, even among brands there are good and bad units/series.
For example I refuse to buy any Corsair whether is an AX or not, I don't trust them.
Then I pointed to some models to other brands you named Seasonic(G series), Antec (TruePower), Silverstone (Strider Gold S), and Enermax (Revolution X't). Can you elaborate on them a little further?

I'm on a 4670K, with up to 4.2Ghz of OC, so 600w or more is fine for me.
 
Bookmark this page. It's a invaluable resource and tells you everything you need to know about psu's. It tells you who the OEM is, wattage on the 12v rail and links to reviews. It's updated regularly and should be in everyones bookmarks.

A thing to note about capacities. Just because it says 400w, 500w 600w on the side of the psu doesn't mean that it can actually deliver that on the 12v rail where it is most needed. Many psu's (especially the cheaper ones) have very weak 12v rails and make up for it on the minor rails where it is not needed these days.
 
Thanks Ace Modder, too late for me, I just bought the whole rig.
pastymuncher I know that page, anyways it's not written in stone, it sometimes has some inaccuracies as proven to me before, what I'm worried about is more about Ripple, Fan Noise, and the theory of fanless mode (a gimmick?). I decided to not buy anything below Gold rated 600w. (edit: I don't really need that much power on the 12v rail, running a haswell -OC'ed though-, and a small K600 Quadro)

So all in all it's a question of whether:
Silverstone Strider Gold S
Enermax Revolution X't
Seasonic G
Seasonic X

I think you are going to get this no matter the price you pay. Similar to CPUs 'Silicon Lottery'. While the majority of the units are pretty good, you'll get that 1 in 10 regardless.

I think your view is slightly skewed:

The AX series are made by the daddy of PSU's (Seasonic), not Corsair themselves, they are just badged for Corsair to sell. There have been reported here of issues even with the Seasonic series. The majority of users here will tell you Seasonic are the best on the market, regardless of who they sell the OEM product too!

You've got no choice but to take the plunge and hope for a decent unit, it's 1 in 10!!!
 
If you fancy something different, go for Super Flower Golden King (funny enough, despite the name it's platinum certified). but they are difficult to source in UK, so yeah, just buy a Seasonic.
 
Sorry guys (for late reply), my rusty graphic controller on mobo was playing hide & seek with me. Since it is already half dead (I guess because a faulty PSU which has already destroyed 2 graphic cards) I didn't think a blow of air would fix it, fortunately I will say good bye to this rig very soon.

@snips86x: My view is not skewed. You venerate Seasonic as if it was the holy grail, and ignore that even inside Seasonic there are from bad (or not so good if you wish) to very good PSU's, that's what I am discussing about. I didn't come here blank, I read a lot about Seasonic and Corsair and you can clearly see how coil whine is a problem far higher on Corsair units.

Does someone consider Seasonix X 650W a good PSU? All the tests I saw show high ripple, they are also famous (unlike the G series) for coil whine as with the Corsairs.

Seasonics do seem to be getting a reputation for coil whine lately, although BeQuiet PSUs made by Seasonic seem to fair better in that regard. Personally, I prefer Delta made power supplies, as do many others on the Jonny Guru forums.
 
But the Dark Power Pro 10 is FSP (Seasonic for 850w and above) also it has a very high ripple (42). What are Delta psu's? I don't remember seeing many.
 
Check out the link pastymuncher left above. It will tell you the OEM of practically all PSUs on the market. It will show you that Corsair, Antec, BeQuiet etc all use a host of different OEMs for different ranges. One of these OEMs are Delta, so you won't see their name blazoned across the unit/packaging!

Antec HCP range are Delta :) They are the king of PSU's but not many people know much about them, so I rarely mention it.

I own 3 Seasonic X series, 2 x 650w and a 1050w and they have been outstanding, no coil whine what so ever and the fan does not even activate in my computers. If i'm building a PC that matters I just purchase a suitable X series PSU job done. From everything i've read the Seasonic G series PSU are also good, yet efficiency and stability is not quite up to the X series.

When I purchased my first X650 in 2009 it was to replace an OCZ SteathXtream. The output voltage was so stable on the Seasonic compared to the OCZ I was able to undervolt the computer more, but keeping same speed.

Thank you JasonM, great help there, I think I got enough feedback to work on. I will try to get the Seasonic G series, mainly because I don't like the fanless thingy of X and others but if buying the G 650W is by any means impossible, then I guess I'm not going to worry much relying on a X one...
About the Antec Delta, I would have loved to put my hands on it, but it's a bit too long for my SFF chassis, I guess price would be a bit too far too, but nice to know about those regardless.

edit: Another thing, what do you think is better (noise wise) for air suction, grill or honeycomb? I will stick this to the Prodigy M front panel, which is already heavily layered.
 
The fanless on X series is only an issue if your relying on the air-flow for your case. Most good modern cases the PSU housing design keeps PSU airflow separate so fanless PSU is no issue.

My 3 X series PSU's are in Silverstone Fortress cases. The extraction area on the PSU is rotated 90 degrees to point upwards, plus PSU intake air is from outside. The PSU intake filters are always free of dust backing up the X series fans are never spinning, however the rotated design of the Silverstone case must be playing a part to keep temps down in passive mode.

This is the case I use the the Seasonics
