If we have a look at the label on the W0156RU, we can see that is identical to the label of the W0133.

+3.3V +5V +12V1 +12V3 +12V2 +12V4 -12V +5VSB
30A 30A 20A 36A 20A 36A 0.8A 3.5A
Max Combined Watts 250W 600W 600W 9.6W 17.5W


Naturally, we can expect the cables to be somewhat different because the cables on the W0156RU are fixed, as opposed to modular....

Type of connector: Toughpower 1200W
ATX connector (450mm) 20+4
2 x 2 12V connectors (500mm) 1*
8-pin Xeon/EPS connector (500mm) 2
6-pin Xeon/AUX connector 0
2 x 3 PCIe (450mm) 3**
2 x 4 PCIe (450mm) 3
5.25" Drive connectors (450mm + 150mm + 150mm) 8
3.5" Drive connectors ( + 150mm) 2
SATA Drive power connectors (450mm + 150mm + 150mm + 150mm) 8
Fan only connectors (thermostatically controlled 12V only) 0
* = One 8-pin splits to make the 4-pin ATX12V connector
** = Three 150mm long 8-pin to 6-pin PCI-e adapters are included
to make a total of six 6-pin PCI-e connectors


I was surprised to see a number of the cables 50mm shorter than they are on the modular version of this power supply. The number of connectors, however, is the same as if you had the modular Toughpower 1200W with all of the cables attached.

Here is a break down of how the connectors are distributed across the four +12V rails:

Rail Wire color Connector OCP
+12V1 yellow/black Main 20+4-pin connector
All peripheral and SATA connectors
+12V2 yellow 4+4-pin ATX12V/EPS12V connector
Half of the 8-pin EPS12V connector
+12V3 yellow/orange Half of the 8-pin EPS12V connector
2 of the 3 6-pin PCI-e connectors
+12V4 yellow/blue 2 of the 3 8-pin PCI-e connectors
1 of the 3 6-pin PCI-e connectors

Inside, we can see that the W0156RU is nearly identical to the W0133.

This model still uses the very unique Channel Well platform Thermaltake's other 1200W uses.

The primary capacitors in the middle of all of these heatsinks are Hitachi.

The secondaries are still Nippon Chemi-Con.

The primary difference is, of course, the fixed DC output cables.  I must say that this aspect of the power supply doesn't look nearly as neat and organzed as the modular version of this PSU.  Then again, you shouldn't be poking around inside your power supply in the first place.  That's my job!

I will tell you that I didn't put the W0156RU on the load tester and run all of the tests that I normally put on a power supply.  I felt that to do so would be very redundant considering I had just reviewed the modular version three weeks ago.  I did quickly put the unit on the load tester and ran a few of the tests I already had programmed on the tester from a previous review and was able to confirm the incredible efficiency numbers.  If you're curious as to how a CWT built Thermaltake 1200W does on the load tester over all, please make sure you check out that other review.  Meanwhile, a 1000W version of this PSU (the W0155RU) is going up on the bench now, will get a thorough review and should be live by next week.

As for scoring the fixed cable version of this power supply; the only part of the score I would change between this unit and the modular unit is to take a point away for functionality due to the loss of a modular interface and the 50MM shorter cables.
