SpecPicks Verdict

SpecPicks scored Thermaltake 500W Power Supply using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. Thermaltake's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Can the Thermaltake Smart 500W power a gaming graphics card?

Yes, for a single mid-range card. It provides two 6+2-pin PCI Express connectors on a single +12V rail with 500W continuous output. Check your GPU maker's recommended PSU wattage before you buy.

Does this power supply work with newer RTX cards that use a 12VHPWR connector?

Not natively. The connector list includes only 6+2-pin PCIe plugs, and the unit is built to the ATX 12V 2.3 spec. Cards that use 12VHPWR would need an adapter, if the card maker supplies and supports one.

What connectors come on the PS-SPD-0500NPCWBZ-W?

One 20/24-pin ATX main connector, one 4+4-pin ATX12V/EPS12V CPU connector, two 6+2-pin PCI Express connectors and six SATA power connectors.

Do I need to set a voltage switch for my country?

No. The input auto-selects between 100V and 240V AC at 50-60Hz with a maximum input current of 8A, and Active PFC is rated at 0.99.

How loud is the fan?

It uses a 4.7-inch fan with automatic speed control, so fan speed rises and falls with load. The listing doesn't publish a decibel rating. The rated operating range is 5°C to 40°C.
