Reviews - Kira CS 630W Power Supply
Sample Provided by: X-Spice (By OklahomaWolf on Mon, Jun-23-2008)

Not too long ago, I received an email from X-Spice asking me to take a look at one of their units and see what I thought of it. Today's review sample, the Kira CS 630W, is the end result of that email. And let me tell you, the moment I opened the shipping box I was anxious to see what it could do. And it's not only because of the hot babe on the box, believe it or not. It was because the retail box itself was so small. How in tarnation did they get a 630 watt power supply into such a small package, I wondered. But, I restrained myself long enough to break out Mr. Fuji and grab some pictures so I could introduce you all to the Kira 630.

But before I do that, there's already some promising stuff on the front of the box. No, it doesn't come with a katana. But it does come with 80 Plus certification. While not gifted with a bronze rating by the efficiency minded people over at the 80 Plus program like its 530W brother, a quick glance over at the website claims a typical 85.29% efficiency rating on this model. We'll just have to see about that, won't we?

Some of you may be asking what the difference is for a bronze rated unit in comparison to a standard one like this. Well, bronze is a little more strict, requiring the unit to meet efficiency ratings of 82, 85, and 82 percent at 1/4, 1/2, and full power. Standard, like this one, only requires 80% at those three load levels. Clear as mud? Good. Let's move on.

Another facet of the box presents us with a number of pretty pictures of the connectors on the unit, as well as a list of included goodies. Power supply? Check. Manual? Check. PCIe 6 to 8 adaptor? Check. Mounting Material? Check. Hot babe with katana? Wait, that's just wishful thinking on my part. Sorry.

Master Spice would like me to repeat his comments. Master Spice has threatened me with injury if I do not do so. So, here they are:

  • Ready for Mini, Midi, Desktop and HTPC Cases - ideal size for small systems
  • EMC Secure PSU housing for better protection
  • Perfectly balanced 120mm LED fan with 4 purple laser LED
  • Four 12V Rails provide independent reliable power to the CPU, video card, and other components
  • Latest control technology for an improved automatic control of the Power rails
  • 99% Active Power Factor Correction provides clean and reliable power to your system
  • RoHS standard examined under strict international guidelines SGS
  • Under-voltage protection, and short circuit protection for maximum security
  • Over Current/Voltage/Power Protection, Under Voltage Protection, and Short Circuit Protection provide maximum safety to your critical system components
  • High Quality Standard Production. 100% Burn in proved
  • Supports the latest ATX12V v2.2 and EPS12V 2.91 standards and is backwards compatible with ATX12V 2.01 and EPS12V 2.8 standards systems
  • Guaranteed compatibility with dual-GPU configurations
  • 2 year warranty and lifetime access to X-Spice's legendary technical support and customer service

Now that I've just worn my fingers to the bone typing all that out, there's some nits to pick in that list. EMC secure eh? Not sure what that is. Elementary Microwaved Chicken? Electro Magnetic Children? Early Morning Coffee? Actually, it stands for Electromagnetic Compatibility. Basically, they're telling us the unit can be used without throwing a lot of electromagnetic interference back into the environment.

And while we're at it, I find it very hard to believe there are purple laser LEDs in that fan. For one thing, where's the ANSI laser classification label? And for another thing, for cryin' out loud in a milk pail, what in blazes would they spend extra to use lasers in here for? It's not like they can light up a clear bladed fan any better than normal LEDs could. I betcha right now there are no lasers in that fan. They're standard LEDs, or I'm the King of England.

I must take some issues with the APFC claims too. Power correction is intended to make a complex load appear as a simple one... to the electrical utility. It has zero effect on the outputs of a computer SMPS, because it is applied to the primary AC input only. Just seeing that claim up there that it somehow improves the DC output quality makes me a little hot under the collar. Most consumers wouldn't know what PFC is, see that line, and go around saying, "Dude, you gotta get APFC or your computer will be, like, unstable dude!" I am not most consumers. I know better. Master Spice needs to go back to school on that one.

There is one item of particular interest on this side of the box, however, that I must point out. There is a claim that this unit is only 12.5cm deep. For those of you with teeny tiny cases who need a fair bit of power, this could be a very good thing. Some cases don't have room for a very big unit, and X-Spice clearly aims to help you out if you have one.

Another side of the box gives some details on the 80 Plus program and what it means for Joe Consumer. I need to rest my hands just a bit, so I'll make y'all squint at the picture a while.

Now that the box is open, we can already see that the Kira 630W is a small unit indeed. I don't think I can remember seeing another 600W or better unit in such a shallow case. Let's just get this unpacked and see for sure.

And out comes Tiny Kira, a European spec power cable (oops), a PCI-E 6 to 8 pin adaptor cable, and an encyclopedia. Wait, no, I guess it's an owner's manual. And one of the most comprehensive owner's manuals I've seen too, printed in nine languages.

Tiny Kira barely has enough room in that wee case to house that 120mm fan.

Tiny Kira is finished in a not quite mirrored but smooth dark gray finish. This is the side opposing the label. The "QC Pass" label also serves as the usual warranty void protection for the company, and yours truly wasted no time getting rid of it for page three's work.

Label shot! The specs are pretty well in line with most units of this wattage coming out lately. Because of the small size of this unit, however, I'm going to make the call right now that this is probably not an independently regulated unit. You see, indy regulation takes up space. Space this unit doesn't have. We'll see if I'm right on the next page.

Max Power






All cabling on this unit is done in red and black, except for the two 6 pin PCI-E cables which are black on black to distinguish them. I found no data in the owner's manual on 12V rail distribution, so I had to crack open the unit to determine that. When I did, I found some stuff that bothered me. I'll talk about that on page three. Rest assured that what I found will not impact performance, so we'll go ahead and load test the unit first and see what it's made of.

Meantime, 12V1 goes to one PCI-E connector. 12V2 goes to the other PCI-E connector. 12V3 goes to the EPS12V/ATX12V cable. Finally, 12V4 is divided between the ATX connector itself and the drive connectors.
