Just a hydro series h55 here, pump works like the asetek champ it is, hoses haven't leaked yet, but gotta say, the stock fan is dismal.

I just recently shopped for another psu, and was very tempted by a really good deal on an AX 760, even if it is a little overkill on an i7/970, but settled on a G2 550w for the same price. Not gonna fault that decision.

I think it's a great idea that JG revisit some older popular units, on one condition. Revisit psus that are used, ones close to warranty end that have seen heavy gaming/OC or high load usage. I think reviews like that would go a long way to maybe slowing down some of the Corsair bashing and having an honest opinion as to real value of a psu.
 
Yeah, we just had a discussion about those new Seasonic built units. That's the first review I've seen though. Too bad you can get the same platform in an ACTUAL Seasonic branded unit for less. Still, there's always sales events, so who knows. At least they seem to live up to the name, same as all Seasonic built units of any noteworthiness do.
 


Thanks for the reply. So it's not the plug because I have used the new one provided for by Seasonic, I've also used the old one. I don't have a multimeter so I can't do the test you suggested. I still need help @_@
 
Try a different outlet, preferably a bathroom or kitchen outlet as they usually have a gfci circuit that's grounded for sure. It's a temporary test so an extension cord to the power strip will be fine. If it solves the problem, then its the plug in the wall that's the issue, or maybe the circuit itself, anywhere back to the house panel. If it doesn't, I can't see it being anything else but the psu, since the chances of 2 different cords being bad like that are so small, it almost never happens.

Check the psu screws are seated properly, sometimes the paint on the case vent can interfere with grounding.
 
He is a registered member and his views are respected equal to all others until there is reason to doubt them. It's no secret he has ties to Corsair, or that he has criticised their products on occasion. If your suggestion were to hold water, surely all Corsairs would all be in Tier One.
 
I apologize if I came off derogatory, I was merely questioning why someone would say he does not appreciate this community? Seeing as he is a member here he and his website are obviously respected as, like I stated, it is used to back up most of our ratings, not all. The fact that he has ties to Corsair and he has stated that some of their units are not quality means that he has integrity and is not just concerned about pushing Corsair products.

I would expect this community to do its own thorough testing. Also edited for grammar.
 
Testing a psu thoroughly, the way JG does, isn't near as easy nor as cheap as it may sound. Very few have the resources to afford the specific equipment needed. Some of the gear costs $thousands for a single piece of equipment, and isn't easy to get. Then of course is the knowledge of how to use it correctly. Not to mention knowing the exact component and it's details, is it junk, is it quality etc. JG has had years to accumulate such knowledge, equipment and experience. Most haven't.

I, for one, can appreciate his efforts and has more than earned the right to his opinions, whether others agree or disagree. If he says the nex650 is good, I'm inclined to believe him, today. But just like the CX, it may not be come tomorrow. Since I don't know of him testing aged, broke in, abused units, I'm not gonna hold today's opinions against tomorrow's reality.

Just my 2¢, sorry if it offends anyone.
 
I use those all the time at school. Those are really reliable in my experience. They have been through several rebuilds in our case. Granted, all we have are two Hard drives with a hotswap bay, a gt210, i5, and a few other odds and ends(budget cuts prevent any upgrades), but I would trust those any time.

From the three years I've used them, and the few years prior to me, I would say tier 2 or 3. I brought that PSU into discussion a while back..


As a side note, Bestec is one of HP's main OEM's according to my searches... That power supply died(I turned and unplugged everything before it took other things out with it) and have a Seasonic ordered up. 300 watts this time. It has two 12 volt rails, which worries me a bit, but it should be fine, right? It was the only option besides SolidGear and Apevia...
 
Nothing wrong with split rail psus, they work the same as a single rail psu, but share the load, so require smaller valued components. The only quibble about a split rail design is you can't just add up the total amperage, so a 20A (12v1) + 20A (12v2) doesn't equal 40A. You must instead go by the combined wattage. If the above was 420w, the combined Amps =36A. The Seasonic S12II /M12-II, Antec HCG 520w /620w are split rail tier2 psus.
 


Firepower is what I call a fireball. I would not want one anywhere near anything I owned.

Corsair HX with an i at the end are Tier 1 units.
Corsair HX units were discontinued best I can tell, which removes them from our list. But I seem to remember them at Tier 3 if I remember right. I would not want one of those.

Try these. They are all top end power supplies.

SeaSonic S12II 620W 80+ Bronze Certified Non-Modular ATX Power Supply $68.99

EVGA 110-B2-0750-VR 750W 80+ Bronze Certified Semi-Modular ATX Power Supply $89.99 - $10 mail in rebate = 79.99

XFX P1-750S-NLB9 750W 80+ Bronze Certified ATX Power Supply $78.99

EVGA 110-B2-0850-V1 850W 80+ Bronze Certified Semi-Modular ATX Power Supply $109.99 - $20 mail in rebate = $89.99

 


Where did you ever get the idea that the Seasonic S12II, M12II and Antec HCG 520W and 620W models have dual +12V rails?

They are only single +12V rail PSUs despite what the label shows. There's no shunt separating the supposed two +12V rails. Even the PS223 monitoring chip that provides OCP only uses a single channel to monitor the current draw on the +12V rail. If it were a real dual +12V rail design then two channels of the PS223 monitoring chip would have been used to monitor each +12V rail.
 
Firepower is the old OCZ and PC Power and Cooling power supply division. Since 2008 they haven't made anything worse than tier 3 and most of their units are tier 1 or 2. Seasonic, Super Flower and Sirtec are their main OEMs. That particular unit is an older Sirtec made unit. You can do better for the money today but it's in no way a bad power supply and when new was competitive with other similarly priced units.

All Corsair HX units are tier 1.
 
The HX 650 is based on the Seasonic G platform. Excellent unit. And yes, more than sufficient for your build.
 
Maybe from http://www.seasonicusa.com/M12II-Bronze.htm

Thank you! And is buying a used (but good condition) PSU a good or bad idea?
