PSU tier list 2.0

[Karadjgne]

For an FSP, that looks very promising. Would be nice to know the original platform, or if this IS an original. Either way, looks like somebody did their homework.

This was already looked at back at the beginning of the month, but not in any real depth or involving a tear down, here at Tom's.

EVGA is about to screw themselves with the BD series soon to be released. HEC crap.

Is that basically the B3?

Also, and yeah the GQ are good but not even comparable to the G2 which are like the same price.

 

[Grawlixz]

Actually, the majority of HP desktops I've ever worked on were micro-ATX cases that could either accomodate a standard ATX power supply or required an mATX power supply. Plus, a whole bunch of proprietary crap, same as with Dell, Compaq, E-machines and Gateway.

I got an HP agent to admit that the PSU is definitely too low of a wattage, but they did not have the form factor of the PSU. I suppose I'll just call HP on Monday, try to upgrade the wattage of the PSU before they send it, and hope I get a good one. What wattage should I be trying for with the specs here? I think the GPU is around 600 and CPU is around 80.

 

[Karadjgne]

If HP will drop you a brand name quality psu instead, you should be looking at 650w. If they give you a stock HP replacement, I'd be shooting for a 750w. You really don't want to push OEM psu's anywhere close to limits, for any extended amount of time. Temporary is ok. OEM psu's generally aren't built for high end gpu punishment that games can dish out.

 

[Darkbreeze]

Unless it's a GOOD Delta OEM unit. And that's not to say that ALL Delta built units ARE good, but some of them are. I'd probably just wait until it comes, take measurements and look at the motherboard connectors and get a replacement unit from there. Anything they throw your way is highly likely to be overpriced and still not terribly good.

 

[PureBlackFire]

You give me no options then. Both PSU are granted with 80 plus gold, this give no indication to be at least reliable? Any other thing i find in the budget will be 80 plus bronze or below and no review either.

as stated 80+ =/= equal relative quality. 10 years ago most every 80+ gold psu was a top of the line psu simply because it was already expensive to make an 80+ gold psu. now that the cost has plummeted, you don't even see 80+ silver anymore because mkaing a psu 80+ gold is just as cheap, if not moreso. today you can find no shortage of either low end or shoddy (or both) power supplies rated 80+ gold. and as a rule of thumb, you get what you pay for. if you find one 80+ gold psu and the next 20 psus at it's price are all bronze, 99.9% of the time that 80+ gold unit is easily worse than half those bronze rated units or one of the worst 80+ gold psus on the market.

And I think they test efficiency in like 20C temperatures.

80+ certification is done at 25c

it is an original design. many of fsp sourced units are custom designs.

The 850W-1000W are a custom platform, it's not a rebrand. I published a leak about them two months before they launched, but unfortunately couldn't know the platform back then.


I don't know if you people heard, but EVGA is also preparing BD and BQ series - both by HEC, ranging from 450W to 850W, and 80+ Bronze.
Here's some information for a start: http://www.orionpsudb.com/news/evga-will-launch-yet-another-line-bq-by-hec (don't pay a lot of attention to amperage tables in the documents - it's hard to get someone at THIS factory to get the values to line up).
Also excuse me for linking to my own site - you don't have to go there if you don't want to, but there are some more details if you're interested.




And while I'm here: it's month-old news, but maybe it's still news to someone - Corsair will give the CX line a total refresh, and it will now contain a CX450, CX550 and CX650. They will be built on a new, modern design with DC-DC converters on the secondary - so another step towards a collective phase-out of all the popular group regulated units on the market. They won't use all Japanese-brand capacitors to keep the costs low.

They will also attack the German market with the new "Vengeance" series. Which will be the same as the new DC-DC CX series, but in 400W/500W/550W/650W flavours (German buyers love low load levels), all Japanese-brand capacitors and multiple rails (3x25A and 4x25A, respectively).



Thoughts?

 

[Turb0Yoda]

Wait, three 12 volt rails? What am I misreading on that Vengence Series.

 

[orionfotl]

Sure, German customers love multiple 12V rails (and Japanese-brand caps!), and that series is supposed to cater to them.

 

[Turb0Yoda]

hmm

 

[Deleted member 217926]

About time they refreshed the CX line. And since they are different output than the existing CX line it won't even be hard to recommend them without hunting down model numbers! No more "do I have a V1, V2 or V3?" It's like someone at Corsair actually listened for once :lol:

 

[Karadjgne]

Musta only been listening with 1 ear. If they'd used both, Corsair would drop the CX and call it DX instead. I'm sure it's all just a marketing strategy, based on world-wide CX sales, but still, at least the Germans get a 'Vengeance' series to differentiate.

And hey! We in the States love Jap Caps too. Wonder if anyone will make an affordable psu out of nothing but Rubycons. Wouldn't mind seeing just what that would do on the test bench.

My thoughts exactly. It is of surprising quality/performance for an FSP OEM unit

 

[tiny voices]

This CX refresh is stupid. They are leaving the 2 worst units EXACTLY the same (750/850). It's BS marketing.

to be fair, the 850 watt version was fine, not great, not bad. still don't see the point of low end 700+ watt psus even existing, but that's just me I guess. I was really surprised to hear they were bumping the wrranty on the CX750 and not changing the unit at all though. it feels deceptive.

 

[tiny voices]

They reason they exist is to make money. There is no chance that the cx750 doesn't carry the largest profit margin of the CX line.

It is very deceptive.

I'm looking forward to seeing the reviews and pricing of the 'new' CX units.

 

[turkey3_scratch]

What are the new ones called? If they're called CX, how can we tell them apart?

 

[Turb0Yoda]

Different model numbers and new visuals on the labels on the PSU I believe.

 

[Archaic59]

They come in new power ranges of CX450, CX550 and CX650. that's the easiest way to tell.

 

[Karadjgne]

Which pretty much falls right in line with the rest of the tiers, 500 crap, 550 good, 600 crap, 650 good

 

[freekyeight]

it would be helpful to put a estimated price range for each tier.

 

[Turb0Yoda]

it would be helpful to put a estimated price range for each tier.

That varies too much with sales and constant shifting prices. Also, some of the Thermaltakes and Raidmax's get expensive, but are still junk.

 

[Onus]

It seems to me it ought to be possible to make a solid 200W basic business-system (no PCIe power) PSU for <$30. Those 300W Seasonics are good, but their price keeps climbing, steadily toward the $40 mark.
