RE: Power consumption... by: Theo Valich on 4/10/2009
I would not say Blacks are hungry. But I would say that it is ludacris to have 1kW PSU with less than 200W available for the 3.3 and 5V rails.

Who is going to use four or five graphics cards... or three gtx285? According to Valve's stats, only 2% of all users use multi-gpu systems, that including dual-gpu cards such as gtx295 or 4870X2. However, the number of users who need 4-5 hard drives is significantly higher... thus it is not understandable that a SATA rail with six connectors on runs out of juice when you plug in drive number five. and to put a Molex2SATA adapter is really... well, amateurish. And 1,2kW PSU in 400W drawing machine is... leaving conclusion to you :)

Hmm that's odd... by: General Lee D. Mented on 4/5/2009
Are the Caviar Blacks really that power hungry? I mean is that metered use or just spec sheet worst case scenario? Staggered spinup on RAID controllers is there for a reason, it takes several times normal operating power to accelerate the platter from rest than to perform even heavy seeks. This is why servers never spin down their HDs to save power, a simultaneous spinup would blow most PSUs and a staggered one can take over a minute on a large array.

I used to run 8 320GB WD Caviar SE16s on a 3Ware 9650SE, an MSI P965 Platinum with a Kentsfield 6600 @ 3.66GHz/1.7v, a Swiftech Apex Ultra, an MSI 8800GTX @660/2250, plus a full complement of fans for a Lian Li PC2000B PlusII all off this little Aopen AO700ALN PSU. Rails were 30A 3.3v 30A 5v 18A 12v1, 15A 12v2. Total on that is 645W.

Ran steady as a rock for a couple years (I would freak people out by pulling the 8pin EPS 12v line out of the board while running 3Dmark and watch it keep going), and that CPU's thermal output alone was calculated at 300W. The electrical input from the PSU must have been well over that.

Though I heard (and believed) rumors it was actually a 900W PSU that Aopen rebranded as 700W because nobody trusted a 900W at that price point and nobody shopping in that price class needed 900W. ;)

Right now my favorite is the Silverstone SST-OP1000-E, a 150mm square PSU with a single 80A rail: http://www.silverstonetek.com/products/p_contents.php?pno=OP1000-E&area=usa Good for those DFI Lanparty JRs in small cases. Now if only I could afford stuff like that.

My dear General,

as soon as we're able to afford General salary bracket, consider yourself hired ;)

We're building this site, and as we all know, economical climate isn't exactly "peachy". We're reaching our internal milestones as we go, expect a lot of news in the next couple of weeks.

Getting onto the subject, a "Good PSU" is really important. And from now on, you can expect that there will be a site that will pay attention to folk that aren't interested in putting ton of graphics cards, but increase storage as well.

I went through 2 OCZ, 2 Thermaltake, 1 Hiper and 1 Tagan PSU (all equal or above 850W) to find a unit that gave 170W on 3.3/5V rail... why, you might ask... well, if you want to put six 500GB WD Black hard drives in RAID6, you do need at least 150W for SATA ports.

We'll pay attention to this element too. It is rubbish that you need 1.1 kW unit for a system that features 120W QC CPU, 107W 9600GSO 768MB card and several low-power PCIe x1 Audio cards... overall, for 420W system (measured at wall), I needed to use 1.1kW unit. A disgrace.
wow by: Takanobi on 4/3/2009
always good to see efficiency go up, i'd have to agree with General Lee that many people do overlook the importance of a good psu
Ok, I see whitespace has been fixed. by: General Lee D. Mented on 4/3/2009
Complaints about comment formatting issues retracted. Thanks. Now how 'bout a preview button or confirm to post? ;)
Minor issues. by: General Lee D. Mented on 4/3/2009
Always good to see the PSU getting improved. It's one of the most overlooked and underrated components in desktops. But a computer is like a pyramid, and the analog voltage input is the base. When it's unsound, everything above it suffers. Mysterious performance issues that don't appear on benchmarks are often a symptom of this.

(I can has paragraph break here plz?)

Anyway, you forgot one of the more important features mentioned in OCZ's press release on the Z-series: "a single +12V rail to support over-clocking efforts". Also, "World of power supplies" should probably be "The world of power supplies", and you never indicate the proper subject in the second paragraph, just "the company stated". Which company? Oh, it's OCZ as I can only tell by squinting at image on the article.

(Break again please. Any word on a better comment parser with whitespace support?)

P.S. As you can see I often copyedit and fact-check free of charge, which some tell me is a mistake. But the part that I believe is worth paying for is where I do it behind the scenes instead of pointing it out in the public comments where readers can see it. So basically if you hire me I'll stop rubbing faces in errors publicly. ;)
