SinTek 500XPS (aka 500 SLI) 500W Power Supply

I’ve never heard of SinTek, but apparently their niche is power supplies. What a coincidence! That’s my niche too!

Below, you can see photos of the detailed SinTek box. SinTek wishes to offer the consumer, not just a modular power supply, but a modular power supply with voltage controllers, a fan speed controller and an LCD temperature display.

Inside the box we find our power supply, a bundle of modular cables, a power cord and a manual.

The PSU is cooled by a 120MM blue LED fan on the bottom and an 80MM fan in the rear. There is a mesh grill on either side of the PSU. This mesh really serves no purpose as the side of the fan housing are immediately on the other side of where we see this mesh. It does make the unit look cool.

You can also see the temperature display in both the above and below photos. Unfortunately, the display is too high up on the PSU housing to be seen through the side panel window in most cases.

The modular interface of the SinTek is probably one of the nicest looking I’ve seen. The aluminum surface of the housing is embossed where the connectors are mounted. The holes for the connectors are cut just large enough to allow for the connector to stick through. The four “dots” you see in the corners are actually the “nut” side of the screws that hold the interface to the power supply housing.

The connectors are labeled, “SATA,” “Peripheral” and “PCI-e.” The SATA and Peripheral connectors are actually interchangeable. If you look closely, you’ll see the PCI-e is actually keyed differently.

Let’s count the connectors on the modular cables we get with the SinTek….

SinTek 500XPS 500W – Cabling
Type of connector:
ATX connector 20+4
2 x 2 12V connectors 1
2 x 3 PCIe 2
8-pin Xeon/EPS connector 0
6-pin Xeon/AUX connector 0
5.25″ Drive connectors 6
3.5″ Drive connectors 1
SATA Drive power connectors 6
Fan only connectors (thermostatically controlled 12V only) 0

As you can see from the photo below, the cables are very nicely sleeved and heat-shrink tubing is used right up to the base of each connector.

The label on the SinTek is all screwed up. Notice the -3.3V. Is that new to the ATX12V spec? Where’s the +5VSB? Also, do the math: (-12V) X (2A) = 10W??? (-5V) X (0.6A) = 7.2W???

Below is the what the specs are supposed to be…

You’ll notice that on the inside of the power supply that there’s a couple knobs. One knob is labeled “Memory” and it controls the voltage on the 3.3V rail. The other knob is labeled “PCI Express” and it controls the 12V rail.

What struck me funny is that memory isn’t the only thing that uses 3.3V and PCI Express isn’t the only thing that uses 12V and when you turn the knobs it’s not like only the voltage on those particular leads are affected. In my opinion, they should just be labeled 3.3V and 12V. If they have to dumb it down so much that they can’t even label the knobs for the appropriate voltage, then they’re addressing people that shouldn’t be allowed to adjust their own voltages in the first place!

I will say that the knobs definitely work. I set the “Memory” knob so the output of the 3.3V rail was exactly 3.3V during load test one, and I set the “PCI Express” knob so the output of the 12V rail 12.10V during load test one (it was bound to drop.) Below is a picture of the other side of the knob. There nothing significant to see here. I just like taking pictures of electrical components.
