Thermaltake Litepower LP-450AH2NF (W0293RU)

Thermaltake’s Litepower series includes inexpensive PSUs of average wattage.

The 450W model comes in a medium-sized box made of matte cardboard.

The text on the back of the box informs you that there is indeed a PSU inside. You can also see a table listing connectors the different Litepower series models are equipped with.

Exterior Design

Save for the stickers and color, the PSU looks exactly like most of the other products in this review. Its 120mm fan is shifted towards one side, too.

There are vent holes in the panel with cables.

Circuit Design

The UL certificate number (E190414) refers to FSP and the internal design of this model is in many points similar to the above-discussed Antec VP450P, also manufactured by FSP.

In fact, the Litepower LP-450AH2NF only differs from the Antec VP450P in some minor details like the component layout in the middle of the case, the smaller central heatsink, and the different brand of the capacitors.

Thermaltake employs Teapo capacitors which enjoy a better reputation than the CapXon capacitors of the Antec PSU.

Otherwise, this model is exactly like others of its class, featuring active PFC and lacking dedicated voltage regulation.

Cables and Connectors

The Litepower LP-450AH2NF is equipped with the following cables and connectors:

  • One mainboard cable with a 20+4-pin connector (40 cm)
  • One CPU cable with a 4-pin connector (40 cm)
  • One graphics card cable with a 6-pin connector (40 cm)
  • One cable with three PATA power connectors (40+15+15 cm)
  • One cable with two PATA power connectors and one floppy-drive plug (40+10+10 cm)
  • One cable with four SATA power connectors (41+13+13+13 cm)

The mainboard’s 20+4-pin cable is the only one to be sleeved. The rest of the cables have one strap until the first connector. There is another strap between the connectors on the PATA power cables.

The cables aren’t long enough to connect to a PSU in a bottom bay unless you use an extension cable for the mainboard.

It’s also not good that the available SATA power connectors all share the same cable. You will hardly be able to connect more than a couple devices if one of them is an optical drive. It would be better to have more SATA instead of PATA power connectors, especially as the latter are mostly used in modern PCs for powering fans.

Specifications

Despite the overall similarity to the Antec VP450P, the Litepower LP-450AH2NF has more impressive specs. It can give you up to 408 watts (or 90% of its full power) across the two +12V lines. The +5V line has a higher load capacity, too, as it can give you up to 120 watts (24 amperes) out of 123 watts, which is the combined load capacity of the +5V and +3.3V lines.

As opposed to the Antec, the Litepower LP-450AH2NF features official 80+Bronze certification.

UPS Compatibility

The PSU was stable with my APC SmartUPS SC 620 at loads up to 357 watts when powered by the mains. They switched to the UPS’s batteries normally at loads up to 325 watts.
