It arrived in perfect condition. Although it only had a piece of Styrofoam on top and small cardboard boxes keeping it snug, nothing was damaged in any way.

Here is what the front of the box looked like.

3 Velcro “Ties”

I thought the Velcro ties were really nice, because you can reuse them if you need to take your power supply out, unlike zip ties which have to be cut and thrown away.

The power supply itself was painted black, with a sticker on one side showing the electrical specs. It has a large 120mm fan on the bottom to help keep it cool.
It also came with an on/off switch in the back which was located on the left hand side.

The owners manual was small and contained installation instructions, electrical specifications, descriptions of the connectors, safety and EMI certifications, a few warnings and trouble shooting, along with sigmas website. It also had French, German, and Spanish wording.

The power supply has been certified by the following safety and EMI certifications: UL, CB, CE, CSA, VDE, Nemko, FCC, BSMI, and GOST.

The power supply comes with six 4 pin molex connectors, 6 sata connectors, two 4 pin floppy connectors, two 6 pin pc-express connectors, two 4 pin atx12v connectors, and a power connector that can fit both 20 and 24 pin.
This is one of the things I liked, the amount and length of wires was awesome. The wires were all wrapped in a black mesh, which looked really cool and also hid all the different colors of the wires.

CONCLUSION
Based on the results, this power supply has no problem delivering power to my system, and I have no doubts in its ability to standup to a high system. The power supply didn’t even bulge a muscle during any of the tests, which didn’t surprise me seeing that my system is a little outdated.

The 120mm fan did an awesome job of keeping it quiet and cool. The only thing I could hear was my video card fan and the two 120mm case fans.

Sigma definitely made a good product here, and it has the power to make any gamer happy delivering ample power. It is a four 12v rail system so users might find it difficult “balancing” all of the loads across the rails.

This power supply came with two six pin PCI-Express connectors, which will make a lot of gamers happy since they will have no trouble having two video cards running at the same time. It does also support ATX Crossfire, for all you ATI fans out there.

The Sigma SP-700 Power Supply is nicely priced at around 104.99-120.99 depending on where you go to buy it. Sigma seems relatively new to the computer scene, but if this power supply is any indication of the quality of their products. I think they will have a lot of satisfied customers in the future.


• Design – 9/10 The quality was great, with its 120mm smart fan which kept it quiet, the SLI and Cross-Fire connectors which makes it capable of supporting dual video cards, the wires were sleeved in a black mesh and came with plenty of length. I only wish it was modular like my previous power supply.

• Cooling – 10/10 The 120mm fan does an awesome job of keeping the unit quiet and cool to the touch.

• Performance 10/10 – The SP-700 never showed signs of fatigue and had no problem delivering power to my system. I believe it can perform well on high end systems with dual video cards and dual core processors, which is what it was built for.

• Ease of use – 9/10 The SP-700 came with a lot of connectors and plenty of wire length. I think this power supply would work very well on users with high towers. I had a little trouble hiding the wires since my tower is smaller, but any veteran builder shouldn’t run into any problems keeping things neat, with the three Velcro ties that came with the unit.

Overall rating – 9.5 frags out of 10.
Which earns Clan Team Xtreme Approved!

[[cTxP]Neutralit]

for the money its not a bad PSU, did you find that you were wishing that it was a modular, so that you didnt end up having needless extra wires in the case? Also, did you feel that if you had a mid size ATX case if the PSU would have fit without a problem...
