80 Plus certified units have been coming out of the woodwork around here lately, and despite repeated calls to the exterminator they don't seem to be stopping their invasion. Today I'm fending off the ongoing attack by looking at the Hiper S625, which comes in at 625 watts of power and boasts Bronze certification. This means that 80 Plus tested one of these bad boys and found that it held up to a minimum 82% efficiency between 20% and 100% of full power.
A compact design is boasted by an equally compact box in the above picture. Other things boasted about are SLI readiness, a three year warranty, and a silent fan *under normal load. So, there are no guarantees about fan silence *under high loads. Why yes, I am enjoying poking fun at the box's fine print. Thank you for asking.
The box also advertises RoHS compliance as well as the fact that it was designed in the UK. "85% efficiency - save energy bill up to 15%." I'm confused here... does that mean it will save me 15% of all my energy bills, thus increasing the chance I'll never get another SaskEnergy bill? What about SaskPower? SaskTel? Oh wait, that's not an energy bill. Rats.
You know, the way things work around here, one of these days I fully expect to wake up and find that the provincial government has SaskChanged the SaskName of the SaskProvince to SaskSask. I mean, come on guys... after a while the whole thing just gets SaskGoofy.
Moving along to the side of the box, Hiper has provided us with a nice little cabling diagram for the unit, as well as a small load table. A load table with some rather nonsensical numbers in it, but I'll get into that later on this page.
Meantime, here's the back of the box, featuring all the marketing bullet point goodness you can eat. No, I didn't eat the box... that's just silly. Besides, I'm all out of barbecue sauce. The marketing stuff is reprinted in twelve languages in type only a gnat could read, so I'll be nice and type it out for you:
Support NVIDIA® SLI™
High efficiency at >85%
Mesh body construction eliminates hot spots and extends the life of the unit
Four independent 12V rails
Complies with latest ATX12V v2.2 form factors
Fully compatible with AMD 64 bit and Intel LGA processors
Gold plated connectors for minimum power loss and optimal conductivity
20 dB(A) under normal load
Once again, Hiper seems to have gone with the perforated housing idea on this unit. And once again, I have my doubts about its effectiveness. Some Hiper units don't do too bad with it, but others end up spewing a bunch of heat back into the case. We'll have to see what the story is for this model on page two.
Our final box picture shows off a bunch of cool little icons, as well as an efficiency graph that promises some pretty impressive results, all at 115VAC. Shall we tell them that they spelled "braiding" wrong?
The box contents proved to be a little sparse. A power supply, bag o' screws, power cable, and a user guide. That's it.
And the user guide was a bit sparse as well. Just a piece of paper folded in fourths. And two panels were blank. Don't strain yourselves there, Hiper.
The S625 itself is finished in matte gray, a somewhat pleasant change from the usual matte black. I'm not sure if I like it any better, but I'm not sure if I really dislike it.
From this angle, you can just make out a plastic baffle inside the unit. These are present on both sides, likely to aid in channeling airflow in the absence of solid side walls, and to provide insulation. 'Tis nice that the cables are sleeved all the way into the unit. This is particularly necessary in this case because the S625 is totally lacking a grommet around the cable exit.
Still still, I like redundancy redundancy and would like to see see a grommet grommet in addition to the sleeving sleeving. Better safe than SaskSorry. Sorry.
There's not much to look at on the rear grille of the unit. Just the usual power switch and AC receptacle.
Here's the label, and all its nonsensical numbers. Seriously, what's the point of quad 12V topology if the combined 12V rails stop at only 40A? Isn't this rating a bit low for a 625W unit in the first place? And what's up with 12V1 and that weirdly low 12A rating? Sense makes this does not.
Type of connector:
6 pin PCIe (480mm)
4+4 pin ATX12V/EPS12V connector (520mm)
ATX connector (490mm)
5.25" Drive (450mm+150mm+150mm)
3.5" Drive connectors (+150mm)
6+2 pin PCIe (460mm)
6 pin PCIe (+50mm)
Unit Dimensions(L x W x H)
140mm x 150mm x 86mm
Now that the cabling is all stretched out in front of us, we can try and make sense of the rail distribution. 12V1 and its odd 12A rating is dedicated to a single 6 pin PCI-E connector, it turns out. Meantime, more strangeness is found when the SATA connectors are shown to be on the same 12V rail as the other two PCI-E connectors. Why not just put them with the Molex connectors? 18A is enough for all that, it's not like people are going to be running this thing with thirty hard drives anyway.
I gotta level with you - secretly, I suspect this may not be a multiple 12V design at all. I'll use the SunMoon to figure that out on the next page.
